Ingredients
  

Base Mixture

  • 1 3/4 cups rolled oats
  • 2 tablespoons flaxseed meal
  • 2 tablespoons chia seeds
  • 1/2 cup protein powder (vanilla plant-based) works great
  • 3/4 cup natural “drippy” peanut butter no added oils or sugar
  • 1.5–2 tablespoons coconut oil adjust based on peanut butter consistency
  • 1/2 cup honey add more if you prefer sweeter bars

Chocolate Coating

  • 1/2 cup chocolate chips
  • 1/2 tablespoon coconut oil

Instructions
 

Preparation

  • Line an 8×8 baking pan with parchment paper and set aside.
  • In a large mixing bowl, stir together the dry ingredients: oats, flaxseed meal, chia seeds, and protein powder.
  • In a microwave-safe bowl, add the peanut butter, coconut oil, and honey. Microwave for 10–15 seconds, then stir until smooth and fully combined.
  • Pour the peanut butter mixture over the dry ingredients and stir gently until the mixture is thick and evenly coated.
  • Transfer the mixture to the prepared pan. Using your hands or a spatula, press it firmly and evenly into all corners.
  • Refrigerate for about 45 minutes, or freeze for 20 minutes, until firm.

Chocolate Coating

  • Melt chocolate chips and coconut oil in the microwave in 10-second intervals, stirring between each, until smooth.
  • Pour the melted chocolate over the chilled bars and spread evenly. Refrigerate again for about 15 minutes until the chocolate sets.
  • Slice into bars and enjoy.

Notes

For firmer bars, add a bit more oats or an extra tablespoon of flaxseed meal. Swap peanut butter for almond or cashew butter for a flavor change. Mix in chopped nuts or seeds for extra texture. Store in the refrigerator for up to 2 weeks or freeze for long-term meal prep.
