Ingredients

  • 1 cup natural peanut butter (smooth or crunchy based on preference)
  • 1/2 cup honey or maple syrup (for a vegan option, use maple syrup)
  • 1 1/2 cups rolled oats (gluten-free if needed)
  • 1/2 cup chocolate protein powder (whey or plant-based)
  • 1/4 cup unsweetened cocoa powder
  • 1/4 tsp salt
  • 1 tsp vanilla extract
  • 1/4 cup mini dark chocolate chips (optional but highly recommended)
  • 2-3 tbsp milk of choice (almond, oat, or cow’s milk)

Equipment

  • Mixing bowl
  • Measuring cups and spoons
  • Spatula or wooden spoon
  • 8×8 inch baking pan or square container
  • Parchment paper
  • Refrigerator
  • Knife (for slicing bars)

Instructions

  1. Prepare your pan: Line the 8×8 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later.
  2. Mix wet ingredients: In a large mixing bowl, combine the peanut butter, honey (or maple syrup), and vanilla extract. Stir well until smooth and fully incorporated.
  3. Add dry ingredients: Add the rolled oats, chocolate protein powder, cocoa powder, and salt to the wet mixture. Stir to combine. The mixture will be thick and slightly crumbly.
  4. Adjust consistency: Slowly add the milk, one tablespoon at a time, mixing after each addition until the mixture holds together but isn’t too sticky. You want a pliable dough-like texture.
  5. Fold in chocolate chips: Gently fold in the mini dark chocolate chips to distribute evenly.
  6. Press into pan: Transfer the mixture to your prepared pan. Using the back of a spatula or your hands, press down firmly and evenly to create a compact layer.
  7. Chill: Place the pan in the refrigerator for at least 2 hours to allow the bars to set firm.
  8. Slice and serve: Once set, lift the bars out of the pan using the parchment paper. Place on a cutting board and slice into 10-12 bars.
  9. Store: Store bars in an airtight container in the refrigerator for up to one week or freeze for longer storage.

Tips & Variations

“For a nuttier texture, try swapping half the oats with chopped nuts like almonds or walnuts.”

If you want to make the bars vegan, simply use maple syrup instead of honey and choose a plant-based protein powder. For added fiber and crunch, mix in chia seeds or flaxseeds along with the oats.

For a more decadent twist, drizzle melted dark chocolate over the top before chilling. If you prefer a sweeter bar, increase the sweetener by a tablespoon or two.

You can also swap peanut butter for almond butter for a different nutty flavor.

To boost the protein content even further, stir in some chopped roasted chickpeas or puffed quinoa before pressing the bars.
