Skip the fancy gluten-free flours and bake up this indulgent chocolate-peanut butter snack using our secret ingredient: quinoa! Thanks to its nutty flavor, this little seed is not only a gluten-free protein powerhouse, but also a great flavor match for chocolate and peanut butter. Because quinoa adds protein and fiber, this snack cake is an indulgent but reasonable afternoon treat for you or any picky eaters in your life. If you like to plan ahead, cook the quinoa in advance to save time. We’re flexible on the chocolate for this recipe--feel free to use chocolate chips or discs. If you prefer milk chocolate, go ahead and use that.
