If you’ve never tried this style of cake, now is the time. Dump cake is fun to make—a lot like cobbler but so much easier to whip up. In fact, a dump cake is just about the simplest dessert you can bake, so named because you just toss the ingredients together and dump them into a baking dish.

Blueberries explode into sweet, fragrant, jammy goodness that infuses the cake with its bold flavor.
