5-Ingredient Berry Cobble (aka Dump Cake)

Servings 8 servings
Prep Time 5 mins
Cook Time 1 hr


  • Cast Iron Skillet


  • 2 pounds fresh or frozen berries
  • 3 tablespoons cornstarch
  • 3 tablespoon sugar
  • 1 16 to 18 ounce box, vanilla cake mix
  • 12 tablespoons butter cubed


  • Stir 2 pounds of berries, 3 tablespoons sugar, and 3 tablespoons cornstarch together in a 12-inch cast iron skillet or 9X13 baking dish, or anything ovenproof with similar dimensions.
  • Pour 1 (16 to 18 ounce) box of cake mix evenly over top. Scatter 12 tablespoons of butter, cut into cubes, over the top.
  • Bake at 350°F for 50 minutes to an hour, until the cake turns light brown, but still very soft looking. No worries if there are a few dry spots, they’ll dissolve right in when you scoop it out.
  • Serve with Vanilla Ice Cream and/or whipped cream!
