  • 3 1/2 c blueberries
  • 2/3 c sugar
  • 1/2 c butter (plus 1-2 T more if needed)
  • 1 15.25 oz. cake mix (I used Betty Crocker super moist yellow)
  • 2 1/2 tsp lemon zest, separated


  • Preheat oven to 350°F. 
  • In a greased 9x13 baking pan, toss together sugar, blueberries and 1 tsp lemon zest. Spread out evenly into the pan. 
  • Pour cake mix over top of the berries to cover completely. Sprinkle the other 1 1/2 teaspoon of lemon zest (can always use a bit more if desired!) over top of the cake mix and using a spoon or your fingers try to gently incorporate it into the cake mix.
  • Slice the butter thin, into about 1/4 in thick pieces and spread evenly all over the cake mix. Place in the oven and bake for about 45-55 minutes or until bubbly and to the desired brown color.
  • Remove and allow to cool. Serve warm with a big scoop of vanilla ice cream. Refrigerate leftovers for 2-3 days.
