Just because we must grow up, that doesn’t mean we have to put childish things away. These peanut butter and jelly bars have all the flavors of a childhood snack baked into a sophisticated dessert. If you’re craving the nostalgic comfort of a classic flavor combination, these are the treat for you. Feel free to put your own twist on the recipe by swapping in your favorite flavor of jam or jelly (Chef Alex thinks peach would be delicious).
