Add 1/3 cup cashew butter, 1/3 cup oat flour, 1/2 cup chocolate protein powder, 2 tablespoons maple syrup, 2 tablespoons ground flaxseed, 3 tablespoons Greek yogurt, 1 tablespoon melted coconut oil, 1 tablespoon cocoa powder, 1 teaspoon vanilla extract, 1/2 teaspoon mint extract, and 1/4 teaspoon sea salt to a food processor or mixing bowl. Mix until a thick, uniform dough forms.Check the texture by rolling a small amount of dough into a ball. It should hold together without sticking to your fingers. Add a spoonful of yogurt if dry, or a light sprinkle of oat flour if sticky. Line a small loaf pan or square pan with parchment paper. Press the dough firmly and evenly into the pan. Sprinkle mini chocolate chips on top and gently press them in. Freeze for about 15 minutes, until firm enough to slice.
In a small bowl, stir in 1/4 teaspoon spirulina powder and 1/8 teaspoon turmeric for natural green coloring with melted coconut oil. Add 1/4 cup white chocolate chips and microwave in 25 second intervals, stirring in between, until smooth and melted.
Remove the bars from the freezer and lift out of the pan. Cut into desired size. Drizzle melted white chocolate over the top. Return to the fridge or freezer until firm and enjoy!
