Mint Chocolate Protein Cookies (10g Protein!)

Brownie-rich mint chocolate protein cookies deliver 10 grams of protein in every generously sized cookie. Made with flaxseed meal, plant-based protein powder, cocoa, and almond butter, they are vegan, gluten-free, and added oil-free—and the batter comes together in one bowl.

Introduction

When I want chocolate that feels like real comfort, a little piece of candy does not always do the job. I would much rather pull out a bowl and bake something deeply chocolatey—especially when the result is as straightforward and satisfying as these cookies.

Each generously sized cookie has a rich cocoa flavor, a cool touch of peppermint, plenty of miniature chocolate chips, and 10 grams of protein. The texture lands somewhere between a soft cookie and a brownie: thick, moist, and substantial rather than crisp or cakey.

I started with my 4-Ingredient 100% Flax Power Muffins as a very loose guide, then took the recipe in a decidedly more dessert-like direction with plant-based protein powder, cocoa, almond butter, peppermint, and chocolate chips. The cookies bake in ten cups of a standard muffin tin, which supports the thick batter and gives them their neat, round yet chunky shape.

If you have been searching formint chocolate protein powder recipesthat go beyond the usual shake, these cookies are a satisfying place to start. You do not need a mint-flavored powder, either: vanilla or chocolate rice protein powder plus peppermint extract creates the chocolate-mint flavor.

Why You’ll Love This Recipe

Ingredients

The exact amounts of each ingredient are indicated in the recipe card at the end of the post.Toggle betweenUS Customary(volume) andMetric(weights) for preferred measurement option.

• Flaxseed meal:Ground flaxseed gives the cookies structure and helps the thick, egg-free batter hold together. Use flaxseed meal rather than whole flaxseeds.
• Chocolate mint,vanilla or chocolate rice protein powder:Rice protein powder was used to test the recipe. It contributes protein and absorbs some of the liquid. Protein powders vary considerably, so the batter may need a small adjustment when another type or brand is used.
• Unsweetened cocoa powder:Provides the deep chocolate base. Use unsweetened cocoa, not a sweetened cocoa drink mix.
• Coconut flour:A small quantity absorbs moisture and helps create the dense, brownie-like texture. Measure carefully because coconut flour is especially absorbent.
• Fine sea salt:Sharpens the cocoa and chocolate flavors.
• Nondairy milk:Unsweetened almond milk, cashew, oat, or soy milk can be used. Keep a little extra nearby in case your protein powder makes the batter unusually dry.
• Smooth almond butter:Adds richness, moisture, and structure. A smooth, well-stirred almond butter will blend into the batter most easily. Any other smooth nut butter can be substituted.
• Pure peppermint extract:Gives the cookies their cool mint flavor. Even if you are using chocolate mint protein powder, you will want to add some extra mint. Peppermint extract is potent, so measure it carefully and adjust only according to taste. If you want less mint flavor, omit or use a tsp of vanilla extract.
• Miniature semisweet chocolate chips:Scatter over the tops for pockets of melted chocolate. Choose vegan and certified gluten-free chips when needed.

How to Make Mint Chocolate Protein Cookies

Note that the complete instructions are also in the recipe card below.

1. Prepare the oven and pan.Preheat the oven to 325°F (160°C). Grease or spray 10 cups of a standard muffin tin. For strictly oil-free cookies, line the cups with silicone or paper baking cups instead.
2. Whisk the dry ingredients.In a medium bowl, whisk the flaxseed meal, protein powder, cocoa powder, coconut flour, and salt until evenly combined.
3. Add the wet ingredients.Stir in the nondairy milk, almond butter, and peppermint extract until the batter is smooth and fully blended. It should be very thick and brownie-like, but still moist.
4. Fill the muffin cups.Divide the batter evenly among the 10 prepared cups and smooth the tops with eh back of a wet spoon. Sprinkle each portion with the miniature chocolate chips.
5. Bake the cookies.Bake for 19 to 22 minutes, until the centers are slightly puffed and the surfaces look dry apart from the melted chocolate chips.
6. Cool before removing.Place the pan on a wire rack and cool the cookies for at least 20 minutes. Run a knife around the edge of each cup, then gently lift out the cookies.

Taste and Texture

Chocolate leads, peppermint follows, and the miniature chips add little bursts of sweetness. The cookies are thick, soft, and brownie-like, with a moist, substantial crumb. They are not traditional crisp or chewy cookies; think of them as compact brownie cookies with enough structure to pick up and eat by hand.

Serving Suggestions

Serve a cookie with coffee, tea, or a cold glass of nondairy milk. The large size also makes one straightforward to pack as a substantial afternoon snack. For dessert, pair it with fresh berries, a spoonful of nondairy yogurt, or a small scoop of vegan ice cream.

Storage

Let the cookies cool completely before storing them in an airtight container. Keep them at cool room temperature for up to 2 days or refrigerate for up to 1 week. For longer storage, freeze the cookies for up to 3 months.

Tips for Success

The mixture should resemble thick, moist brownie batter. Protein powders absorb liquid differently, so add a little more nondairy milk if the batter looks dry or crumbly. If it looks too wet, stir in coconut flour a few teaspoons at a time.

The thick batter will not spread and level like conventional cookie dough. Smooth each portion in its muffin cup before adding the chocolate chips.

The recipe makes ten generously sized cookies. Dividing the batter into more cups will produce smaller cookies and may change the baking time.

Give the cookies the full 20-minute cooling time before lifting them out. The rest allows the egg-free cookies to set and makes them easier to remove intact.

Ingredient Substitutions

I tested the recipe with vanilla rice protein powder. Other vanilla or chocolate plant-based protein powders should work, but their absorbency varies. Adjust with a little more nondairy milk if the batter is too dry, or a few teaspoons of coconut flour if it is too wet. I do not recommend whey protein powder for this recipe.

Use another smooth nut or seed butter, such as peanut butter, cashew butter, sunflower seed butter, or tahini. Each will change the flavor slightly. Choose sunflower seed butter for a nut-free version, provided all of your other ingredients are also nut-free.

The flaxseed meal helps the cookies hold together. I have suggested ground chia seeds or about 2 teaspoons of whole psyllium husks as possible alternatives, but I have not tested either option in a full batch. Expect the texture to change.

Flavor Variations

Omit the peppermint extract and add about 1 teaspoon of espresso powder or 1 tablespoon of instant coffee powder.

Replace the peppermint extract with 1/2 to 1 teaspoon of orange extract, or add 1 teaspoon of finely grated orange zest.

Omit the peppermint and use 1/2 to 1 teaspoon of vanilla or almond extract. For a warm spiced version, add 1/2 to 1 teaspoon of cinnamon or cardamom.

Frequently Asked Questions

No. The tested recipe uses vanilla rice protein powder, although chocolate rice protein powder is also an option. Cocoa powder, peppermint extract, and chocolate chips create the mint chocolate flavor.

I have not tested the cookies with a mint chocolate protein powder. If you try one, use a plant-based powder and reduce or omit the peppermint extract according to the flavor of your powder. Check the batter consistency before baking because protein powders vary in absorbency.

The muffin cups support the thick, flourless batter and give the cookies their substantial round shape. I recommend using the muffin tin rather than transferring the batter to a flat baking sheet.

Line five muffin cups with silicone or paper baking cups instead of greasing or spraying the pan. Also check the labels on your protein powder and chocolate chips if avoiding added oil is important to you.

The original recipe contains almond butter and may use almond or cashew milk. For a nut-free version, use sunflower seed butter and a nut-free nondairy milk, and confirm that the protein powder and chocolate chips meet your needs.

Store the completely cooled cookies in an airtight container at cool room temperature for up to 2 days or in the refrigerator for up to 1 week. Freeze them for up to 3 months.
