This Oil-Free Vegan Cookie Dough Bark is one of the easiest no-bake sweet treats you can make. With simple ingredients like oat flour, maple syrup, and my favorite sunflower seed butter from Sunbutter, it comes together in no time with a chocolate layer that will also satisfy chocolate lovers—vegan, oil-free, nut-free, refined sugar-free, gluten-free, and simply delicious!
