These no-melt dark chocolate peanut butter protein bars are easy to make, packed with flavor, and perfect for on-the-go snacking or post-workout fuel. They stay firm even in warm conditions and combine rich dark chocolate with creamy peanut butter and protein-packed oats.

Ingredients

Scale
  • 1 cup (250 g) natural peanut butter (creamy or crunchy, unsweetened)
  • 1/3 cup (80 ml) honey or maple syrup
  • 2 tablespoons (30 ml) melted coconut oil
  • 1 teaspoon (5 ml) vanilla extract
  • 1 1/2 cups (135 g) old-fashioned rolled oats
  • 1/2 cup (45 g) whey or plant-based protein powder (vanilla or unflavored)
  • 1 tablespoon (15 g) chia seeds (optional)
  • Pinch of salt
  • 1/2 cup (90 g) dark chocolate chips (at least 70% cocoa)

Instructions

  1. Line an 8×8-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal.
  2. In a mixing bowl, combine peanut butter, honey or maple syrup, melted coconut oil, and vanilla extract. Stir until smooth and creamy. Microwave peanut butter for 15 seconds if too stiff.
  3. Add rolled oats, protein powder, chia seeds (if using), and salt to the wet mixture. Stir until evenly combined and thick but sticky.
  4. Gently fold in dark chocolate chips without overmixing.
  5. Transfer mixture to the prepared pan and press firmly and evenly using a spatula or lightly greased hands.
  6. Chill in the refrigerator for at least 2 hours until firm. 90 minutes may suffice but full chilling makes slicing easier.
  7. Lift the slab out using parchment overhang and cut into 10-12 bars with a sharp knife.
  8. Store bars in an airtight container in the fridge for up to a week or freeze for longer storage.

Notes

Press the mixture firmly into the pan to avoid crumbly bars. Use good quality protein powder for best taste and texture. Chilling is essential to set the bars and maintain the no-melt texture. For vegan or dairy-free options, use plant-based protein powder and maple syrup instead of honey. Adding a pinch of sea salt on top before chilling enhances flavor.
