Ingredients

Ingredient	Quantity
Creamy peanut butter	1 cup
Protein powder (vanilla or unflavored)	¾ cup
Maple syrup or honey	⅓ cup
Dark chocolate chips	½ cup

Instructions

Step 1

Line a small baking dish or loaf pan with parchment paper. In a mixing bowl, combine the peanut butter, protein powder, and maple syrup or honey until a thick dough forms.

Step 2

Press the mixture evenly into the prepared pan using a spatula or the back of a spoon so the base becomes compact and smooth.

Melt the dark chocolate chips in a microwave-safe bowl in short intervals, stirring until smooth.

Step 4

Spread the melted chocolate evenly over the pressed protein base. Refrigerate for about 1 hour until firm, then slice into bars before serving.
