Equipment

Ingredients
  

  • 6 cups blueberries fresh or frozen
  • ½ cup granulated sugar
  • 2 tablespoons cornstarch
  • 2 tablespoons lemon juice
  • 1 box yellow cake mix
  • ¾ cup unsalted butter cut into ⅛-inch-thick slices
  • 2 tablespoons unsalted butter cut into ⅛-inch-thick slices
  • ¼ teaspoon ground cinnamon

Instructions
 

  • Preheat the oven to 350°F and grease a 9x13-inch baking dish with 2 tablespoons of butter.
  • Combine the blueberries, sugar, cornstarch and lemon juice in a medium-sized saucepan and cook over low heat until bubbly and thickened. About 8 minutes.
  • Spread the blueberry filling evenly in the greased baking dish.
  • Sprinkle the dry yellow cake mix evenly over the filling and arrange the butter slices evenly over the cake mix. Dust with ground cinnamon.
  • Bake for 35 to 40 minutes, until golden brown and bubbly.
  • Cool for 10 minutes before serving.

Notes

Chef Jenn’s Tips

  • Make sure to slice the butter thin so it melts evenly and covers the cake mix well.
  • If you’re using fresh berries, taste them first and adjust the sugar as needed.
  • You can swap yellow cake mix for white or butter cake mix depending on what you have on hand.
