Step‑by‑Step Instructions for Homemade Peanut Butter Protein Bars

Step 1: Prepare Pan
Start by spraying or lining your 8×8 or 9×9 pan with parchment paper to prevent sticking. Ensure the paper overhangs the edges slightly, making it easier to lift out the bars later. This simple preparation step will save you time when you’re ready to cut and serve your delicious Homemade Peanut Butter Protein Bars.

Step 2: Melt Mixture
In a microwave-safe bowl, combine the creamy peanut butter, coconut oil, and honey. Microwave this mixture for 30–45 seconds until the coconut oil is melted and everything is warm. Stir until you achieve a smooth consistency, making sure there are no lumps remaining. This creates the luscious base for your chewy protein bars.

Step 3: Combine Ingredients
Once your mixture is smooth, add in the vanilla extract, salt, cinnamon, flax meal, protein powder, and old-fashioned oats. Stir vigorously until all ingredients are fully integrated, creating a sticky and cohesive mixture. This step ensures the nutrients and flavors meld together beautifully in your Homemade Peanut Butter Protein Bars.

Step 4: Fold in Extras
Gently fold in the coconut flakes and mini chocolate chips, being careful not to overmix. The extra ingredients should be evenly distributed throughout the mixture, adding delightful texture and richness. This is where the magic happens, transforming your bars into a treat that’s both nourishing and delicious!

Step 5: Shape Bars
Transfer the mixture into the prepared pan and press it down firmly with a spatula or your hands, smoothing the top for a neat finish. If desired, sprinkle extra chocolate chips and flaked salt over the surface for added appeal. Take a moment to admire the creamy, nutty texture of your Homemade Peanut Butter Protein Bars before moving on.

Step 6: Chill
Refrigerate your pressed mixture for 10–15 minutes, allowing the bars to set. This chilling time helps the ingredients bind together, providing a firmer structure for cutting. When ready, the top should feel slightly firm and hold its shape while still being slightly soft to the touch.

Step 7: Cut and Serve
Once your bars are chilled and firm, remove them from the pan using the parchment overhang. Place them on a cutting board and use a sharp knife to cut them into squares or rectangles. With their chewy texture and nutty flavor, these Homemade Peanut Butter Protein Bars are now ready to be enjoyed as a tasty snack or a post-workout boost!
