Ingredients

Scale

Main Ingredients

  • 1 cup creamy natural peanut butter (must be natural, with oil separating out)
  • 5 tablespoons maple syrup
  • 1 teaspoon vanilla extract
  • ½ cup oat flour
  • 60 grams vanilla whey protein powder (about 1/2 cup + 2 tablespoons)
  • 1 tablespoon mini chocolate chips
  • ¼ cup mini M&M’s

Instructions

  1. Combine Ingredients: Add the creamy natural peanut butter, maple syrup, vanilla extract, oat flour, and vanilla whey protein powder into a large mixing bowl.
  2. Mix the Base: Use an electric mixer or a silicone spatula to thoroughly mix the ingredients until the mixture is smooth and well combined.
  3. Add Mix-Ins: Fold in the mini chocolate chips and mini M&M’s evenly throughout the dough to distribute them well.
  4. Shape the Bars: Line a loaf pan or meal prep container with parchment paper. Press the mixture firmly and evenly into the container using your hands or a spoon to create a thick, compact base.
  5. Freeze to Set: Cover the container with plastic wrap and place it in the freezer for 1 hour or until the mixture is firm enough to cut.
  6. Cut into Bars: Remove the parchment paper from the container and slice the set mixture into 6-8 bars, depending on desired size.
  7. Store Properly: Wrap each bar individually. Store refrigerated for up to one week or freeze in freezer bags for up to two months to maintain freshness.

Notes

  • Use natural peanut butter with oil separation for best texture and flavor.
  • Oat flour can be homemade by blending rolled oats until fine.
  • Protein powder quantity can be adjusted based on dietary needs or preferences.
  • Bars can be customized by swapping mini M&M’s for other mix-ins like nuts or dried fruit.
  • Keep bars well wrapped to prevent drying out.
