Equipment

Ingredients

  • 24 ounces Frozen blueberries
  • 1 teaspoon Vanilla
  • 2/3 cup White sugar
  • 1 tablespoon Cornstarch
  • 15.25 ounces Yellow cake mix 1 box
  • 3/4 cup Unsalted butter melted

Instructions

  • Start by preheating your oven to 350℉.
  • Spread all of the blueberries into the bottom of your baking dish.
    24 ounces Frozen blueberries
  • Sprinkle the vanilla, sugar, and cornstarch on top, as evenly as possible.
    1 teaspoon Vanilla, 2/3 cup White sugar, 1 tablespoon Cornstarch
  • Then sprinkle the cake mix on top, ensuring all blueberries are completely covered.
    15.25 ounces Yellow cake mix
  • Drizzle the melted butter on top of the cake mix, covering as much of the dry ingredients as possible.
    3/4 cup Unsalted butter
  • Bake for about 50 minutes, or until the top starts to golden and there are barely any dry spots.
  • Allow to cool slightly, then enjoy with some vanilla ice cream!

Notes

  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 to 4 days. To reheat, microwave individual portions in 20 to 30 second increments until warm.
  • To freeze, let cool, then wrap tightly with plastic wrap and freeze for up to 2 months. Thaw overnight in the fridge and reheat in the microwave or in the oven at 325°F until warmed through.
  • After drizzling the melted butter on top, gently tilt the baking dish in different directions to help the butter spread and cover more of the dry cake mix. Don't worry about getting every inch covered.
  • Your cake is done when the top is golden brown around the edges with very few dry spots remaining. The center may still look slightly underdone, but it will continue to set as it cools.
  • You don't need to mix the sugar, cornstarch, and blueberries together before adding the cake mix.
