About the Oat Flour

You can easily find oat flour at most grocery stores. Alternatively, you can make your own by blending rolled oats in a high-speed blender until they’re finely ground. A food processor isn’t recommended because it won’t grind the oats fine enough. If you need gluten-free muffins, be sure to use certified gluten-free oats.

Step-by-Step Guide to Baking Applesauce Oat Flour Muffins

The complete, detailed directions are also provided in the recipe card below.

Step One: Preheat and Prepare the Muffin Pan

Start by preheating your oven to 375°F (190°C). Line a standard 12-count muffin tin with silicone liners for easy removal. If you’re not following an oil-free diet, you can lightly spray the muffin cups with nonstick cooking spray instead of using liners.

Step Two: Combine the Dry Ingredients

In a large mixing bowl, whisk together the oat flour, flaxseed meal, coconut sugar, baking powder, cinnamon, and salt. Make sure all the ingredients are fully combined to ensure even distribution of flavors and leavening.

Step Three: Add the Wet Ingredients

Add the unsweetened applesauce and water to the bowl with the dry ingredients. Stir until everything is completely blended and the batter is smooth. Don’t overmix, as this can make the muffins tough.

Step Four: Portion the Muffin Batter

Divide the muffin batter evenly among the 12 prepared muffin cups. Fill each cup almost to the top rim. This will give the muffins a nice, tall dome when they bake.

Step Five: Bake the Muffins

Bake the muffins in the preheated oven for 17–20 minutes, or until the tops are golden brown and a toothpick inserted into the center of a muffin comes out clean. Baking time may vary depending on your oven, so keep an eye on them.

Step Six: Cool the Muffins

Let the muffins cool in the muffin pan on a wire rack for about 15 minutes before removing them. Allow the muffins to cool completely for the best texture. They’re delicious warm, but their texture improves as they cool.

How to Store Your Applesauce Oat Flour Muffins

Store the cooled oat flour muffins in an airtight container at room temperature for up to 2 days. For longer storage, keep them in the refrigerator for up to 1 week, or freeze them for up to 6 months. To thaw frozen muffins, simply leave them overnight in the refrigerator or use the defrost setting on your microwave before serving. These muffins are a great make-ahead option for busy weeks!

Ingredient Substitutions for Applesauce Oat Flour Muffins

Need to make some changes? Here are a few simple substitutions you can try:

Sweetener Options: If you don’t have coconut sugar, you can use an equal amount of brown sugar, maple syrup, date syrup, agave nectar, brown rice syrup, or honey (if you’re not vegan). If you use a liquid sweetener, reduce the amount of water to 3 tablespoons instead of ⅓ cup.
Applesauce Substitute: In a pinch, you can use an equal amount of very ripe mashed banana instead of applesauce. This will add a slight banana flavor to the muffins.
Flaxseed Meal Substitute: Ground chia seeds can be used in place of flaxseed meal in equal amounts. They have similar binding properties.

Flavor Variations and Add-Ins for Your Muffins

These applesauce oat flour muffins are delicious on their own, but they’re also a great base for adding your favorite flavors and textures. Here are some ideas to get you started:

Extracts: Add 1 teaspoon of vanilla extract, ½ teaspoon of almond extract, or ½ teaspoon of orange extract to the batter for a subtle flavor boost.
Spice Variations: Experiment with different spices! Replace or combine the cinnamon with ground ginger, cardamom, nutmeg, allspice, or a pumpkin spice blend. You can also sprinkle the tops of the muffins with cinnamon sugar before baking.
Mix-Ins: Fold up to ½ cup of your favorite mix-ins into the batter just before portioning. Try mini chocolate chips (use dairy-free if needed), chopped nuts (such as walnuts, pecans, almonds, or hazelnuts), sunflower seeds, pumpkin seeds (pepitas), dried fruit (like dried cranberries, raisins, or chopped dried apples), or chopped dates.

Serving Suggestions for Applesauce Oat Flour Muffins

Enjoy these applesauce muffins for breakfast, a snack, or any time of day. They’re great plain, or you can dress them up with almond butter, sunflower seed butter, plant-based butter, or a spoonful of jam. They’re also delicious lightly toasted and drizzled with maple syrup or topped with a few slices of banana. Sturdy and not overly sweet, they pair perfectly with morning coffee or afternoon tea.
