Equipment

Ingredients
  

  • 6 cups blueberries frozen
  • ½ cup granulated sugar
  • 2 tablespoons corn starch
  • 2 tablespoons lemon juice
  • 15.25 ounces 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 your oven to 350°F. Lightly grease a 9x13-inch baking dish using 2 tablespoons of the butter.
  • Mix together the blueberries, sugar, cornstarch, and lemon juice in a medium saucepan. Cook over low heat for about 8 minutes, stirring occasionally, until the mixture thickens and starts to bubble.
  • Pour the blueberry mixture into the prepared baking dish, spreading it out in an even layer.
  • Evenly sprinkle the dry cake mix right on top of the fruit mixture—don’t stir. Arrange the butter slices over the cake mix, spacing them out to cover as much surface as possible. Finish with a light dusting of ground cinnamon.
  • Place the dish in the oven and bake for 35–40 minutes, or until the top is golden and the filling is bubbling around the edges.
  • Let it cool for about 10 minutes before serving. Best enjoyed warm, especially with a scoop of vanilla ice cream.

Notes

Chef Jenn's Tips

  • Thinly sliced butter helps it melt evenly and coat the cake mix properly.
  • Taste fresh berries if using, and adjust the sugar depending on their sweetness.
  • Yellow cake mix is great, but white or butter-flavored mixes also work well.
