How to Make Protein Brownies (Step-by-Step)

Preheat oven to 175°C / 350°F. Line an 8×8” baking pan with parchment paper.
In a bowl, mix wet ingredients: yogurt, peanut butter, maple syrup, egg, vanilla, and milk until smooth.
In another bowl, whisk dry ingredients: oat flour, protein powder, cocoa powder, baking powder, and salt.
Combine wet and dry until a thick batter forms. Fold in optional mix-ins.
Pour into the pan, smooth the top, and bake for 18–22 minutes, until just set.
Cool completely, slice into 9 brownies, and enjoy!

Tips for the Best Fudgy Texture

Getting that perfect fudgy texture is all about balance — the right ingredients, bake time, and a few insider tricks. Here’s how to make sure your protein brownies come out gooey, rich, and never dry:

Don’t overbake. The brownies should still be slightly soft in the center when you take them out. They’ll continue to set as they cool.
Use the right protein powder. Whey or a whey-casein blend works best for fudgy results. Plant-based powders can work too, but they may require a bit more liquid.
Add a little fat. A small amount of coconut oil, nut butter, or Greek yogurt helps lock in moisture and richness.
Let them cool completely. As tempting as it is to dig in right away, cooling allows the brownies to firm up and develop that perfect chewy bite.
Optional mix-ins. A few dark chocolate chips or a swirl of nut butter can elevate the texture even more.

Variations to Try

Want to switch things up? These fudgy protein brownies are super versatile, and there are plenty of ways to make them your own:

Peanut Butter Swirl: Drop spoonfuls of natural peanut butter on top before baking and swirl with a knife for a marbled effect.
Mocha Brownies: Add 1–2 tsp of instant coffee granules to the batter to enhance the chocolate flavor.
Vegan Option: Use a plant-based protein powder, flax eggs, and dairy-free milk/yogurt for a vegan-friendly version.
Double Chocolate: Stir in a handful of sugar-free chocolate chips or chunks for extra gooey bites.
Mint Chocolate: Add a dash of peppermint extract for a refreshing twist.
Zucchini Brownies: Sneak in some finely grated zucchini for added moisture and fiber—trust us, you won’t taste it.
