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

1. Preheat your oven to 350°F and line an 8×8 baking pan with parchment paper.
2. In a large bowl, whisk together all dry ingredients until evenly combined.
3. In a separate bowl, whisk the eggs, Greek yogurt, vanilla extract, and peppermint extract.
4. Stir in the melted butter and melted chocolate chips until the mixture looks glossy and smooth.
5. Add the wet ingredients to the dry ingredients and gently fold until just combined.
6. Fold in chocolate chips if using.
7. Spread the thick, rich batter evenly into the prepared pan.
8. Bake for 18–22 minutes, removing when the center is just set. Slight underbaking keeps the brownies fudgy.
9. While warm, sprinkle crushed peppermint candies over the top.
10. Allow brownies to cool fully for clean slices — or enjoy warm for extra gooey brownies.
