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. The bounty of juicy summer fruit, combined with sweet, simple, golden brown cake and whipped cream is very special. Blueberries explode into sweet, fragrant, jammy goodness that infuses the cake with its bold flavor.

No matter how busy you are, you'll have time to make this quick and delicious dump cake. This is a great recipe to have at hand for those occasions when you need to fix up dessert in a hurry. Blueberry dump cake is made with just a few simple ingredients you probably already have in your pantry.

  • 1 (15-ounce) box yellow cake mix

  • 10 tablespoons (5 ounces) cold unsalted butter, plus more for the pan

  • 1 pound fresh blueberries

  • 1/2 cup buttermilk

  • 1 tablespoon pure vanilla extract

For the Whipped Cream:

  • 1 cup heavy whipping cream

  • 1/4 cup confectioners' sugar

  3. Put cake mix into a large bowl. Using a box grater, shred cold butter into dry ingredients. Toss to combine. Or cut butter into small pieces with a pastry blender or mash through tines of a fork. Work quickly to avoid melting butter.

  8. Prepare whipped cream while dump cake is cooling. In a large bowl, or in bowl of a stand mixer, whisk whipping cream and confectioners' sugar until past soft peak stage but not quite stiff.
