- ½ cup Greek yogurt (thick)
- ¼ cup melted butter or coconut oil
- 2 eggs
- ⅓ cup maple syrup or sugar-free sweetener
- 1 scoop chocolate protein powder
- ⅓ cup unsweetened cocoa powder
- ½ cup oat flour (or almond flour)

Step-by-Step Instructions
Step 1: Prep
Preheat oven to 350°F (175°C).
Line an 8×8 baking pan with parchment.
Step 2: Make Brownie Layer
Whisk yogurt, butter, eggs, and sweetener.
Add protein powder, cocoa, flour, baking powder, and salt.
Spread evenly in pan.
Step 3: Make Cookie Layer
Mix almond flour, protein powder, egg, butter, sweetener, baking soda, and chocolate chips.
Spoon cookie dough over brownie layer and gently spread (doesn’t need to fully cover).
Step 4: Bake
Bake for 22–28 minutes.
Center should be slightly soft for fudgy texture.
Step 5: Cool
Cool completely before slicing for clean squares.
Chilling 30–60 minutes gives that thick bakery look.
Additional Notes
- Slight underbake = extra fudgy center
- Protein powder thickens texture naturally
- Use whey for best softness
