Ingredients

  • 4 cups fresh or frozen blueberries
  • 3- ounce box raspberry jello
  • 1/3 cup granulated sugar
  • 1 15.25-ounce box white or yellow cake mix*
  • 1/2 cup salted butter melted
  • 2 cups cold water

Instructions

  1. Preheat the oven to 350 degrees. Lightly spray a 13- by 9-inch baking dish with cooking spray.
  2. Arrange the berries in an even layer in the bottom of the baking dish. Sprinkle the powdered jello over that, then top with the sugar.
  3. Sprinkle the cake mix powder over all of that, then top with the melted butter and the cold water.
  4. Bake for 45 minutes to an hour, until the top is lightly browned and the blueberry juices are bubbling.
  5. You can serve your cobbler warm but it’s MUCH easier to serve if you let it cool for at least a couple of hours so it can set up a bit. It tends to be soupy when it’s warm. I usually make it the night before and serve it cold the next day.

Recipe Notes

  • Uneaten cobbler can be stored in the fridge, covered, for 4 or 5 days or frozen (tightly wrapped) for up to 2 months.
  • *I used Betty Crocker Super Moist yellow cake mix but you can use whatever brand you prefer as long as it’s roughly 15.25 ounces.
  • If you like blueberry and lemon together, you can use lemon jello and lemon cake mix rather than raspberry jello and white/yellow cake mix.
    You’ll need about 15 to 16 ounces of berries to get 4 cups.
  • If you use frozen berries DO NOT defrost them first. Just layer the ingredients over them while they’re still frozen.
  • Depending on how sweet your berries are, you can add a little less sugar; if they’re really sweet I cut the sugar to 1/4 cup. If they’re sour you can add a little more sugar.
  • Be sure to use salted butter; it makes a big difference. If all you have is unsalted, you can mix a 1/2-teaspoon of salt into the butter after you melt it.
  • Sometimes when you make a cake mix cobbler like this you end up with a few pockets of dry cake mix on top; if that bothers you, stir the cake mix, water, and butter together in a bowl until smooth before pouring it over the berries/sugar/jello.
