Ingredients
  

For the Bars:
  • 1½ cups whole grain oat flour
  • ½ cup vanilla protein powder
  • ½ cup creamy cashew butter
  • 6 tbsp pure maple syrup
  • 1 whole lemon juiced and zested
  • 1 tsp pure vanilla extract
  • 1 cup unsweetened dried blueberries
  • 1 pinch fine sea salt
For the Lemon Glaze:
  • ¼ cup powdered sugar
  • 2 tsp fresh lemon juice
  • Extra lemon zest for topping

Method
 

Mix Dry:
  1. In a large mixing bowl, combine the oat flour, vanilla protein powder, sea salt, and the fresh lemon zest. Whisk thoroughly to combine.
Combine Wet:
  1. In a separate medium bowl, stir together the creamy cashew butter, pure maple syrup, fresh lemon juice, and vanilla extract until completely smooth.
Form Dough:
  1. Pour the wet mixture into the dry flour mixture. Stir with a firm spatula until a thick, cohesive dough forms. Gently fold in the dried blueberries until distributed evenly.
Press & Chill:
  1. Line an 8x8-inch pan with parchment paper. Firmly press the dough down into an even layer. Place in the refrigerator to chill for 1 hour until solid.
Glaze & Slice:
  1. Lift the chilled dough block out of the pan using the parchment edges. Whisk the powdered sugar and 2 teaspoons of lemon juice together, then drizzle over the top. Garnish with a final sprinkle of lemon zest and cut into 10 uniform rectangular bars.

Notes

  • Store bars in an airtight container inside the refrigerator for up to 10 days.
  • To keep the recipe fully gluten-free, ensure your oat flour package states certified gluten-free.
  • Using dried blueberries instead of fresh berries prevents the bars from becoming soggy during storage.
