In a mixing bowl or food processor, combine 1/3 cup cashew butter, 2 tablespoons maple syrup, 3 tablespoons Greek yogurt, 1 tablespoon coconut oil, 2 teaspoons vanilla extract, and 1/4 teaspoon almond extract. Mix until smooth, then add 1/3 cup oat flour, 1/2 cup vanilla protein powder, 2 tablespoons ground flaxseed, and 1/4 teaspoon sea salt. Mix until a thick dough forms. Gently fold in 2 tablespoons rainbow sprinkles, being careful not to overmix.
