Ingredients

  • 1 cup rolled oats (gluten-free if needed)
  • 1/2 cup vanilla or chocolate protein powder (whey or plant-based)
  • 1/2 cup natural peanut butter (or almond butter)
  • 1/4 cup honey or maple syrup
  • 1/2 cup mini marshmallows
  • 1/4 cup dark chocolate chips
  • 1/4 cup crushed graham crackers
  • 1 teaspoon vanilla extract
  • Pinch of salt

Equipment

  • Mixing bowl
  • Measuring cups and spoons
  • Spatula or wooden spoon
  • 8×8 inch baking pan or similar size
  • Parchment paper
  • Refrigerator
  • Knife for cutting bars

Instructions

  1. Prepare your baking pan: Line the 8×8 inch pan with parchment paper, leaving some overhang on the sides to easily lift the bars out later.
  2. Mix dry ingredients: In a large bowl, combine the rolled oats, protein powder, crushed graham crackers, and a pinch of salt. Stir until evenly mixed.
  3. Combine wet ingredients: In a microwave-safe bowl, gently warm the peanut butter and honey/maple syrup for about 20-30 seconds until smooth and easy to stir. Add vanilla extract and mix well.
  4. Mix wet and dry: Pour the peanut butter mixture over the dry ingredients. Use a spatula or wooden spoon to stir everything together until fully combined. The mixture should be sticky but manageable.
  5. Add marshmallows and chocolate chips: Fold in the mini marshmallows and chocolate chips carefully to avoid melting them.
  6. Press into pan: Transfer the mixture into the lined baking pan. Press firmly and evenly with the spatula or your hands (dampened slightly) to compact the bars well.
  7. Chill: Place the pan in the refrigerator for at least 2 hours to set. This helps the bars hold their shape when cut.
  8. Cut and serve: Once chilled, lift the bars out using the parchment paper overhang. Cut into 10-12 bars with a sharp knife. Store leftovers in an airtight container in the fridge.

Tips & Variations

For best results, use a high-quality protein powder that you enjoy the flavor of, as it really shines through in this recipe.

  • Vegan option: Use maple syrup instead of honey and choose a plant-based protein powder.
  • Add nuts or seeds: For extra texture and nutrition, mix in chopped almonds, walnuts, or pumpkin seeds.
  • Swap the chocolate: Try white chocolate chips or cacao nibs for a different flavor twist.
  • Make it nut-free: Use sunflower seed butter or tahini if you have nut allergies.
  • Toasting marshmallows: For an authentic campfire flavor, toast mini marshmallows lightly with a kitchen torch before folding them in.
