Ingredients (Makes 9 Large Brownies)

Dry Ingredients

1 cup chocolate or vanilla whey protein powder
½ cup unsweetened cocoa powder
½ cup oat flour (or almond flour for low carb)
½ teaspoon baking powder
¼ teaspoon salt

Wet Ingredients

½ cup natural peanut butter (or almond butter)
⅓ cup honey or maple syrup
2 large eggs
¼ cup Greek yogurt (plain)
¼ cup milk (any type)
1 teaspoon vanilla extract

Optional Add-Ins

¼ cup dark chocolate chips
2 tablespoons sugar-free chocolate chunks
Chopped walnuts
Swirl of peanut butter on top

Step-by-Step Instructions

Step 1: Preheat & Prepare

Preheat oven to 350°F (175°C).

Line an 8×8 inch baking pan with parchment paper.

Lightly grease.

Step 2: Mix Dry Ingredients

In a large bowl combine:

Protein powder
Cocoa powder
Oat flour
Baking powder
Salt

Whisk to remove lumps.

Step 3: Mix Wet Ingredients

In another bowl mix:

Peanut butter
Honey
Eggs
Greek yogurt
Milk
Vanilla

Whisk until smooth and creamy.

Step 4: Combine

Add wet ingredients into dry mixture.

Stir gently until fully combined.

Do not overmix.

Batter should be thick but spreadable.

If too thick, add 1–2 tablespoons milk.

Fold in chocolate chips if using.

Step 5: Bake

Pour batter into prepared pan.

Smooth top evenly.

Bake 18–22 minutes.

Center should look slightly soft but not wet.

Do not overbake — protein brownies dry quickly.

Step 6: Cool Completely

Let cool at least 20 minutes before slicing.

Cooling helps texture firm up.

Cut into 9 squares.

Why This Recipe Works

Protein Powder

Provides structure and boosts protein.

Peanut Butter

Adds moisture and richness.

Greek Yogurt

Prevents dryness and keeps brownies soft.

Eggs

Bind ingredients and improve texture.

Together, these create a fudgy interior instead of a dry protein brick.

Texture Tips

For Extra Fudgy:
Bake closer to 18 minutes.

For Cake-Like:
Bake full 22–24 minutes.

If brownies turn dry:
You likely overbaked or used too much protein powder.

Protein absorbs moisture quickly — measure carefully.

Storage Instructions

Refrigerator:
Store up to 5 days in airtight container.

Freezer:
Freeze individually wrapped brownies up to 2 months.

Reheat:
Microwave 10–15 seconds for warm, gooey texture.

3. Mocha Brownies

Add ¼ teaspoon peppermint extract.

5. Walnut Crunch
