The oatmeal gets infused overnight with sugar, shredded apples, cocoa powder, milk, eggs, and vanilla, then baked off in the afternoon before you plan on serving the dessert. If you want to save time on the day you serve these, slice the mangoes in advance, then cover and refrigerate until you’re ready to assemble the dessert. We like the mangoes sliced, but you can dice them if you'd like. Hang on to leftover bars for breakfast, because who doesn’t enjoy waking up to a little chocolate?
