Ingredients
  

  • ½ cup gluten-free oat flour
  • 2 tablespoons coconut flour
  • 1 to 2 tablespoons granulated sweetener of choice optional
  • ¼ teaspoon sea salt
  • ½ scoop protein powder about 16-17 grams, optional
  • 1½ teaspoons poppy seeds
  • 1 teaspoon lemon zest optional
  • 2 tablespoons nut butter of choice
  • 3 tablespoons pure maple syrup
  • ½ teaspoon lemon extract
  • 2 tablespoons or more milk of choice (dairy-free if necessary)
  • White chocolate chips to drizzle (optional)

Instructions
 

  • Mix Dry Ingredients: In a large mixing bowl, whisk together the oat flour, coconut flour, sweetener (if using), sea salt, protein powder, poppy seeds, and lemon zest. Set aside.
  • Prepare the Wet Mixture: In a microwave-safe bowl or a small pan over low heat, melt the nut butter with the maple syrup. Stir in the lemon extract.
  • Combine: Pour the warm nut butter mixture into the dry ingredients and stir until a crumbly dough forms. Gradually add the milk, one tablespoon at a time, mixing well after each addition. Continue until the mixture reaches a thick, dough-like consistency.
  • Shape and Chill: Transfer the dough into a parchment-lined 4-inch square or mini loaf pan. Press down evenly to create a smooth, compact layer. Refrigerate for about 30 minutes until firm.
  • Finish and Serve: Once firm, drizzle with white chocolate if desired. Slice into bars and enjoy!

Notes

Sweetener Adjustments: If the protein powder you use is already sweetened, you may not need additional sweetener. Adjust to taste.
Sugar-Free Option: Replace maple syrup with sugar-free syrup, but do not heat it with the nut butter. Instead, stir it into the batter at the end. If the dough is too soft, add a bit more coconut flour to firm it up.
Flour Swap: Substitute oat flour with fine-milled almond flour. If using almond flour, you may need to slightly increase the milk to reach the desired dough consistency.
Texture Tips: Bars can be stored in the freezer for a firmer texture or enjoyed straight from the fridge for a softer bite.
