Peppermint Chocolate Protein Brownies Recipe
Yield: 16 thick brownies
Texture: Ultra fudgy with a peppermint-chocolate swirl of bliss
Ingredients
Dry Ingredients
- ½ cup chocolate whey or whey-casein protein powder
- ½ cup all-purpose flour
- ½ cup cocoa powder
- 1 cup sugar (or ¾ cup monk fruit classic sweetener for a lighter option)
- ½ teaspoon salt
- ½ teaspoon baking powder
Wet Ingredients
- ½ cup butter, melted
- ½ cup chocolate chips, melted with the butter
- 2 large eggs
- ¼ cup Greek yogurt
- 1 teaspoon vanilla extract
- 1 to 1½ teaspoons peppermint extract (adjust to taste)
Optional Mix-Ins & Toppings
- ½ cup chocolate chips
- ¼ cup crushed peppermint candies or candy canes
- Melted chocolate for drizzling over cooled brownies
Instructions
- Preheat your oven to 350°F and line an 8×8 baking pan with parchment paper.
- In a large bowl, whisk together all dry ingredients until evenly combined.
- In a separate bowl, whisk the eggs, Greek yogurt, vanilla extract, and peppermint extract.
- Stir in the melted butter and melted chocolate chips until the mixture looks glossy and smooth.
- Add the wet ingredients to the dry ingredients and gently fold until just combined.
- Fold in chocolate chips if using.
- Spread the thick, rich batter evenly into the prepared pan.
- Bake for 18–22 minutes, removing when the center is just set. Slight underbaking keeps the brownies fudgy.
- While warm, sprinkle crushed peppermint candies over the top.
- Allow brownies to cool fully for clean slices — or enjoy warm for extra gooey brownies.
Flavor & Texture Highlights
- A deep chocolate base paired with a cool peppermint finish
- Protein powder adds structure without overpowering flavor
- Butter and melted chocolate deliver classic brownie richness
- Peppermint topping adds crunch, sparkle, and holiday flair
These brownies are soft, rich, and satisfying; the kind you’d proudly serve to guests without mentioning they’re protein-boosted.
