Ingredients

Units Scale

For the Base

  • 3/4 cup natural peanut butter
  • 1/2 cup vanilla protein powder
  • 1/4 cup powdered peanut butter
  • 1/4 cup ground flaxseeds
  • 3 tbsp maple syrup
  • 1/2 tsp salt

For the Topping

  • 1/3 cup semi-sweet chocolate chips
  • 1 pinch flaky sea salt (for garnish)

Instructions

  1. Make the Protein Base: In a medium mixing bowl, combine the natural peanut butter, vanilla protein powder, powdered peanut butter, ground flaxseeds, maple syrup, and salt. Mix thoroughly until a thick and uniform dough forms. This mixture should easily hold together when pressed.
  2. Prepare the Baking Dish: Line a small baking dish (about 8×4 or 8×8 inches) with parchment paper, leaving extra overhang for easy removal. Press the peanut protein mixture firmly and evenly into the bottom of the pan to create a smooth, compact base.
  3. Melt the Chocolate: Place the chocolate chips in a microwave-safe bowl and heat in 20-second intervals, stirring between each interval, until completely melted and smooth.
  4. Add the Chocolate Layer: Pour the melted chocolate over the pressed protein base. Use a spatula to spread the chocolate in an even layer over the entire surface.
  5. Garnish and Chill: Immediately sprinkle a pinch of flaky sea salt over the melted chocolate. Transfer the baking dish to the refrigerator and chill for at least 1 hour, or until the bars are firm and the chocolate is set.
  6. Slice and Store: Once fully chilled, use the parchment paper to lift the bars out of the dish. Cut into 10 evenly-sized bars or squares. Store your homemade protein bars in an airtight container in the refrigerator for up to one week.

Notes

  • Use natural peanut butter (just peanuts and salt) for the best texture and flavor.
  • If the mixture is too dry, add a little more maple syrup or a splash of non-dairy milk.
  • Bar size can be adjusted based on your baking dish and preference—just keep thickness consistent.
  • Try swapping semi-sweet chocolate for dark chocolate for a richer flavor.
  • For a vegan option, ensure the chocolate chips and protein powder are plant-based.
  • These bars can also be frozen for longer storage—just thaw in the fridge before eating.
