  • Gluten-Free: Made with oat and almond flours, these blondies are safe for individuals with gluten sensitivities or celiac disease, ensuring everyone can enjoy a delightful treat.
  • No Added Sugar: The sweetness comes primarily from very ripe bananas, allowing you to enjoy a naturally sweet treat without the need for refined sugars or artificial sweeteners.
  • Only 5 Ingredients: Simplicity is key! With just five core ingredients, these blondies are incredibly approachable, even for novice bakers. Less shopping, less fuss.
  • Made in 1 Bowl: Streamlined preparation means minimal cleanup. All the mixing happens in a single bowl, making baking a breeze from start to finish.

The Wholesome Ingredients You’ll Need

The exact amounts for each ingredient are provided in the comprehensive recipe section at the end of this post. You can easily switch between US Customary (volume) and Metric (weights) measurements there.

Crafting these delectable blondies starts with a selection of wholesome, nourishing ingredients:

  • Almond Flour or Almond Meal: This provides a tender crumb and healthy fats, contributing to the moistness without added oil. Blanched almond flour will give a finer texture, while almond meal offers a slightly coarser, rustic feel.
  • Oat Flour: A fantastic gluten-free alternative that adds a lovely chewiness and depth of flavor. You can buy ready-made oat flour or easily make your own by blending rolled oats until fine. Remember to use certified gluten-free oat flour or oats if strict gluten-free is required.
  • Mashed, Very Ripe Bananas: The star ingredient! Overripe bananas with plenty of dark spots are crucial here. They provide natural sweetness, moisture, and a wonderful banana flavor, eliminating the need for added sugars. The riper the banana, the sweeter and more flavorful your blondies will be.
  • Smooth Nut Butter or Seed Butter: This acts as a binder, adds healthy fats, and contributes to the rich, tender texture, effectively replacing any oil. Options like almond butter, sunflower seed butter, or natural smooth peanut butter all work wonderfully. Choose a runny, smooth variety for best results.
  • Baking Soda: A critical leavening agent that helps the blondies rise slightly and achieve a desirable texture.
  • Optional: Semisweet Chocolate Chips: A classic addition that takes these blondies to the next level of indulgence. You’ll find more fantastic add-in suggestions below and within the recipe card!

The synergy of the natural fats found in almond flour and your chosen nut/seed butter, combined with the abundant moisture from mashed bananas, is what makes these blondies incredibly moist and tender, *without the addition of any oil*. This thoughtful ingredient combination is what makes them so uniquely healthy and satisfying.

Important Note: If maintaining a 100% gluten-free diet is essential, always opt for certified gluten-free oat flour, or ensure the rolled oats you use to make your own flour are certified gluten-free to avoid cross-contamination.

How to Craft Your Delicious Vegan Oil-Free Banana Blondies

Making these blondies is wonderfully simple, requiring just one bowl and a few easy steps. Let’s get baking!

Step One: Preheat Your Oven & Prepare Your Baking Pan

Begin by preheating your oven to 350°F (180°C). Next, prepare an 8-inch (20 cm) baking pan. You’ll want to coat the interior – both the bottom and sides – with a nonstick cooking spray or a light layer of oil/grease of your choice (such as coconut oil or avocado oil). For those who wish to keep the blondies 100% added oil-free, you can achieve this by using a nonstick baking pan or, more reliably, by lining the bottom and sides of the pan with parchment paper. This parchment paper method not only prevents sticking but also makes removing and cutting the chilled blondies much easier.

Step Two: Whisk Together the Dry Ingredients

In a large mixing bowl, combine the almond flour, oat flour, and baking soda. Whisk these dry ingredients together thoroughly until they are well blended and no lumps remain. This step is crucial for ensuring that the leavening agent (baking soda) and flours are evenly distributed throughout the batter, which contributes to a consistent texture in your final blondies.

Step Three: Incorporate the Wet Ingredients

Add the mashed, very ripe bananas and your chosen smooth nut or seed butter to the bowl containing the dry ingredients. Stir the mixture vigorously until all ingredients are completely combined and a uniform batter forms. Don’t worry about over-mixing the batter with this recipe! Since there is no gluten present (thanks to the oat and almond flours), you can stir with confidence and enthusiasm without the risk of making your blondies tough.

Optional: Stir in Your Favorite Add-ins

This is where you can truly personalize your blondies! If you desire, now is the time to fold in your optional semisweet chocolate chips or any other desired add-ins. Gently stir them into the batter until they are evenly distributed. This ensures every bite of your blondie is packed with your chosen flavor accents.

Step Four: Spread the Batter Evenly

Transfer the prepared batter into your greased or parchment-lined baking pan. Using a rubber spatula or the back of a spoon, carefully spread the batter into an even layer across the entire bottom of the pan. Take a moment to smooth the top of the batter. An even layer ensures consistent baking, preventing some parts from being overcooked while others are undercooked.

Step Five: Bake to Golden Perfection

Place the baking pan in your preheated oven and bake for approximately 25 to 30 minutes. The blondies are ready when they are set at the center (a toothpick inserted into the middle comes out clean or with moist crumbs) and the edges have turned a beautiful golden brown. Keep in mind that oven temperatures and environmental conditions can vary, so it’s always a good idea to check for doneness at the earliest suggested time. If needed, continue baking longer, even beyond the maximum time, until they reach perfection. A well-baked blondie will have a firm yet yielding center.

Step Six: Cool Completely and Chill for Best Results

Once baked, remove the pan from the oven and transfer it to a wire cooling rack. Allow the blondies to cool completely at room temperature. This is a crucial step for setting their structure. For optimal slicing and texture, transfer the entire pan to the refrigerator and chill for at least one hour. If you’re in a hurry, you can place the pan in the freezer for about 15 minutes. Chilling the bars solidifies them, making them much easier to remove from the baking dish and cut into clean, uniform pieces.

Once thoroughly chilled, carefully lift the blondie slab out of the pan (especially easy if you used parchment paper) and cut it into 16 bars or squares. Now, they’re ready to enjoy! Yum!

Frequently Asked Questions About Vegan Oil-Free Banana Blondies

How Do I Properly Store These Vegan Oil-Free Banana Bars?

To keep your delicious blondies fresh, store the cooled bars in an airtight container. They will remain fresh at cool room temperature for up to 1 day. For longer storage, refrigerate them for up to 1 week. For extended enjoyment, these blondies freeze beautifully for up to 3 months. When ready to eat from the freezer, simply thaw at room temperature or warm slightly.

What Can I Expect Regarding the Taste & Texture of These Bars?

These banana blondies offer a delightful balance of taste and texture. They are firm yet have a wonderfully tender and lightly moist crumb. The unique combination of almond flour and oat flour creates a texture that is robust but not dense, arguably even better than blondies made with traditional all-purpose flour. The almond flour, along with the nut or seed butter, contributes natural oils that provide a rich mouthfeel and a slightly chewy quality, all without the need for any added liquid oil. The natural sweetness from the ripe bananas shines through, making them a satisfying treat that doesn’t feel overly indulgent.

What Can I Substitute for Mashed Bananas?

If you don’t have ripe bananas on hand or prefer a different flavor profile, you can substitute an equal amount of unsweetened applesauce or pumpkin puree. While these alternatives will work well structurally, keep in mind that the blondies will be significantly less sweet, as bananas contribute a unique natural sweetness. If using applesauce or pumpkin, you might want to consider adding a small amount of an unrefined sweetener, such as coconut sugar or maple syrup, to taste. Start with 1-2 tablespoons and adjust according to your preference. Also, note that the flavor will subtly shift depending on your choice: applesauce provides a lighter, fruitier note, while pumpkin puree will impart a mild, earthy undertone.

Can I Substitute the Almond Flour with Another Type of Flour?

Yes, you can experiment with flour alternatives. An equal amount of DIY Sunflower Seed Flour is a promising substitute for almond flour in this recipe. While I haven’t personally tested it extensively, it should yield good results given its similar fat content and texture. However, a crucial modification is required: **if you use sunflower seed flour, replace the baking soda with 1 and 1/2 teaspoons of baking powder (ensure it’s certified gluten-free if needed).** This is vital because sunflower seed flour, when combined with baking soda, can cause baked goods to turn green – a completely harmless but visually surprising chemical reaction. Using baking powder will help prevent this discoloration.

Can I Make My Own Oat Flour from Rolled Oats?

Absolutely! Making your own oat flour is simple and cost-effective. To do so, place an equal weight of rolled oats (which is typically just under 1.25 cups for 1 cup of flour) into a high-speed blender. Process the oats until they are completely broken down into a fine, consistent flour-like powder. A food processor can be used as an alternative, but it’s generally not the best option for achieving a very fine texture; the results will likely be a bit coarser, more akin to finely ground oatmeal rather than a smooth flour. For the best results in these blondies, aim for as fine a grind as possible.

Does the Type of Nut or Seed Butter Affect the Blondies’ Quality?

Yes, the consistency of your chosen nut or seed butter plays a significant role in the final texture of these blondies. For the best results, these blondies are ideally made with a nut or seed butter that is naturally runny or loose. Whether you opt for cashew butter, almond butter, peanut butter, or sunflower seed butter, prioritize a brand or jar that has a smooth, pourable consistency. If your chosen butter is stiff or thick, gently heat it for a very brief period in a microwave (10-15 seconds at a time) or in a small saucepan over low heat until it loosens up and becomes more fluid. This ensures it mixes easily and evenly into the batter, contributing to the desired moist and tender texture.

Can I Infuse the Blondies with Additional Flavorings?

Yes, absolutely! The base recipe provides a delicious minimalist version, but these blondies are incredibly adaptable to various flavor enhancements. Feel free to unleash your creativity with additions such as:

  • Extracts: Enhance the aroma and flavor with a touch of vanilla extract (about 1 teaspoon for a classic note) or almond extract (a bolder flavor, so typically 1/2 teaspoon).
  • Spices: Introduce warmth and complexity with a small amount of ground cinnamon, cardamom, nutmeg, or ginger. These pair wonderfully with banana and can transform the blondies into a more festive treat.
  • Grated Zests: For a bright, fresh lift, add the finely grated zest of citrus fruits like lemon, lime, or orange. These natural oils impart a vibrant flavor without adding liquid.
  • Sweeteners: While designed to be naturally sugar-free, if you prefer a sweeter profile or are using banana alternatives, you can add a small amount of natural sweeteners like coconut sugar or maple syrup to taste.

Are There Other Excellent Add-In Suggestions (Beyond Chocolate Chips)?

Beyond the beloved chocolate chips, there are many fantastic ingredients you can fold into your blondie batter to create different textures and flavor combinations. Consider adding an equal amount (typically 1/2 cup, unless specified) of any of the following:

  • Dried Fruit: Add chewiness and natural sweetness with chopped dried cranberries, dried cherries, dried blueberries, or finely diced dried apricots.
  • Chopped Nuts or Seeds: Introduce a delightful crunch and extra nutrients with walnuts, pecans, sunflower seeds, or pepitas (pumpkin seeds).
  • Cacao Nibs: For a more intense, slightly bitter chocolate flavor and a fantastic crunchy texture, use 3 to 5 tablespoons of cacao nibs instead of a full 1/2 cup of chocolate chips.
  • Vegan White Chocolate Chips: If you enjoy a different kind of sweet contrast, vegan white chocolate chips can add a creamy, sweet note.

Happy Baking! We hope these incredibly versatile, healthy, and delicious banana blondies become a new favorite in your kitchen.

An oil-free vegan banana blondie with a bite taken out of it, showcasing its moist texture.

Ingredients

  • 1 cup almond flour
  • 1 cup oat flour (see notes for making your own)
  • 1/2 teaspoon baking soda
  • 1.33 cups mashed very ripe bananas (about 3-4 medium bananas)
  • 1/2 cup (128 g) smooth nut butter (e.g., almond butter, peanut butter), runny consistency preferred
  • Optional: 1/2 cup dark chocolate chips (see notes for more options)

Instructions

  1. Preheat the oven to 350°F (180°C). Coat the interior (bottom and sides) of an 8-inch (20 cm) baking pan with nonstick cooking spray. For an oil-free option, line the pan with parchment paper.
  2. In a large mixing bowl, whisk together the almond flour, oat flour, and baking soda until well blended.
  3. Add the mashed bananas and nut butter to the bowl with the dry ingredients. Stir thoroughly until completely combined. If adding chocolate chips or other mix-ins, stir them in now until evenly distributed.
  4. Spread the batter evenly into the prepared baking pan. Use a rubber spatula or the back of a spoon to smooth the top.
  5. Bake for 25 to 30 minutes, or until the center is set and the edges are golden brown. (Note: Baking times vary, so check for doneness at the earliest time and bake longer as needed.) Transfer the pan to a cooling rack and let cool completely.
  6. For easier removal and cleaner cuts, transfer the cooled pan to the refrigerator and chill for at least one hour (or in the freezer for 15 minutes).
  7. Once chilled, remove from the pan and cut into 16 bars or squares.

Notes

  • Storage: Store cooled bars in an airtight container at cool room temperature for 1 day, in the refrigerator for up to 1 week, or freeze for up to 3 months.
  • Make Your Own Oat Flour: Place an equal weight of rolled oats (just under 1.25 cups) in a blender and process until completely broken down into a fine flour.
  • Chocolate Chip Alternatives: For other delicious add-ins, consider 1/2 cup chopped dried fruit (cranberries, cherries, blueberries, apricots), 1/2 cup chopped nuts or seeds (walnuts, pecans, sunflower seeds, pepitas), or 1/4 to 1/3 cup cacao nibs.
  • Banana Alternatives: Unsweetened applesauce or pumpkin puree can replace bananas in equal amounts. If using, you may want to add 1-2 tablespoons of coconut sugar or maple syrup for sweetness, as these alternatives are less sweet than ripe bananas.
  • Almond Flour Alternative: An equal amount of DIY Sunflower Seed Flour can be used. If substituting, use 1.5 teaspoons of baking powder (certified gluten-free, if needed) instead of baking soda to prevent a harmless green discoloration.
  • Nonstick Pan Options: Instead of cooking spray, you can use a small amount of oil (e.g., coconut oil, avocado oil) to grease the pan. For 100% oil-free baking, use a nonstick pan or line with parchment paper.
