How To Make Brownies With Protein Powder
It’s very easy to make a brownie with protein powder using a few basic pantry staples.
Let me share with you how to make egg-free protein brownies.
- Old-fashioned rolled oats – feel free to use gluten-free certified oats if desired.
- Chocolate protein powder – we tested the recipe with pea protein powder and almond protein powder, but any range works well. Keep in mind that every protein powder has different liquid absorbencies and therefore, the texture for the brownies will change based on the protein source you are using.
- Unsweetened cocoa powder
- Baking powder
- Liquid sweetener of choice – feel free to use your favorite refined sugar-free sweetener. The best option includes maple syrup, agave syrup, coconut nectar, rice syrup, or keto-friendly sugar-free maple-flavored syrup.
- Almond milk or any non-dairy milk you love.
- Yogurt – high-protein options are the best, like soy yogurt. Another option is to swap the yogurt for nut butter like almond butter, peanut butter, mashed bananas, or sweet potato puree.
- Dark chocolate chips – feel free to use a sugar-free vegan brand to decrease sugar.
- Vanilla extract
Making The Batter
All you need is a food processor or high-speed blender to make this recipe or ready-made homemade oat flour.
Add all the ingredients except the chocolate chips to the blender and blend on the high-speed setting for about 1 minute.
Add oats, cocoa powder, chocolate protein powder, baking powder, vanilla, yogurt, almond milk, and liquid sweetener.
Blend until all the ingredients come together into a smooth thick brownie batter.
You may have to stop the appliance a few times, scrape down the sides and repeat or use the tamper attachment of your blender to push down the food next to the blade.
Stop the blender, add chocolate chips, and use a wooden or silicone spatula to stir in the chocolate chips. Using a soft tool prevents damaging the blade, so don’t use a metallic spoon.
Transfer the brownie batter onto the prepared pan and spread evenly over the pan.
Preheat the oven to 350°F (180°C). Line a 9-inch square baking pan with parchment paper and lightly oil the paper with oil spray.
Bake in the center rack of the oven for 20-25 minutes.
These brownies dry out fast, so don’t overbake to avoid a dry crumb.
Watch the baking time closely after 20 minutes, inserting a pick in the center, and if clean, take out the brownie pan from the oven.
Cool the brownies down immediately on a cooling rack and wait until fully cooled down before frosting them.
I highly recommend my high-protein frosting recipe for this brownie. This adds up to 2 grams of plant-based protein per serving.
But, you can also use some of my other dairy-free frosting recipes below:
You can add some fruits, nuts, or more chocolate chips to this brownie batter. Simply stir in up to 1/2 cup of:
- Raspberries or chopped strawberries
- Vegan chocolate chips – you can also use vegan white chocolate chips or vegan milk chocolate chips for a change.
- Chopped pecans, walnuts
- Coconut flakes
This protein powder brownie recipe can be stored in the fridge in a cake box for up to 4 days.
You can freeze the brownie entirely, or by single serves, in zip bags for up to 3 months.

Frequently Asked Questions
Can I Use Coconut Sugar?
You can swap liquid sweetener with a granulated option, but the batter will be slightly thicker.
You may want to add 2 extra tablespoons of almond milk or yogurt to balance the texture and avoid a dry brownie.
Can I Increase The Protein Powder?
I don’t recommend adding more protein powder to the recipe, or the batter will be very dry.
Add the protein frosting on top of the brownie for added proteins.
Can I Use Chocolate Whey Protein Powder?
We only recommend plant-based protein powder for baking.
We don’t use animal-based products, but they should work if it’s what you prefer to use in your kitchen.
