Step 1: Prepare Your Pan - Line your 9x5 inch loaf pan with parchment paper, leaving some overhang for easy removal later.
Step 2: Mix the Wet Ingredients - In a mixing bowl, combine the soft peanut butter and the granulated sweetener. Stir until the mixture is smooth and creamy.
Step 3: Add Dry Ingredients - To the peanut butter mixture, add the coconut flour, protein powder, and cocoa powder. Stir until all ingredients are well combined.
Step 4: Shape the Bars - Transfer the mixture into the prepared loaf pan and press it down evenly.
Step 5: Chill in the Refrigerator - Cover the pan and refrigerate for at least an hour to firm up the bars.
Step 6: Cut and Serve - Once chilled, lift the bars out of the pan using the parchment overhang and cut into desired sizes.
