Ingredients

Scale

Dry Ingredients

  • ½ cup oat flour
  • 60 grams vanilla whey protein powder (about ½ cup + 2 tablespoons)
  • 1 tablespoon mini chocolate chips
  • ¼ cup mini M&M’s

Wet Ingredients

  • 1 cup creamy natural peanut butter (must be natural, with oil separating)
  • 5 tablespoons maple syrup
  • 1 teaspoon vanilla extract

Instructions

  1. Combine Ingredients: Add the peanut butter, maple syrup, vanilla extract, oat flour, and vanilla whey protein powder to a large bowl.
  2. Mix Thoroughly: Use an electric mixer or mix by hand with a silicone spatula until all ingredients are well combined and form a dough-like mixture.
  3. Add Chocolate and Candy: Fold in the mini chocolate chips and mini M&M’s evenly throughout the mixture.
  4. Press Into Pan: Line a loaf pan or meal prep container with parchment paper. Press the dough firmly into the container using your hands or a spoon, creating an even, thick base.
  5. Freeze to Set: Cover the container or loaf pan with plastic wrap and place it in the freezer for 1 hour, or until the mixture is firm.
  6. Cut Into Bars: Lift the parchment paper out of the container and cut the set dough into 6 to 8 bars using a knife.
  7. Store Properly: Wrap individual bars and store them in the fridge for up to 1 week or place in freezer bags and keep frozen for up to 2 months.

Notes

  • Oat flour can be made by grinding rolled oats in a food processor until fine.
  • Use natural peanut butter that has oil separation for best texture.
  • For a vegan option, substitute whey protein powder with a plant-based protein powder.
  • Bars can be customized by using different types of mini candies or chocolate chips.
  • If bars are too sticky after thawing, keep them chilled for easier handling.
