Cake:
non-stick cooking spray, for the cake pan
zest of 1 lemon
15.5 oz. box white cake mix, plus ingredients listed on the package to make the cake
Filling:
1 1/2 c. frozen blueberries
1/2 c. sweetened condensed milk
juice of 1 lemon
Topping:
1 1/2 c. cold heavy cream
4 oz. cream cheese, at room temperature
1/2 c. powdered sugar
zest of 1 lemon plus 1 thinly sliced lemon, for garnish
Cake:
Preheat the oven according to the package directions. Spray a 9x13 inch cake pan with non-stick cooking spray.
Fold the lemon zest into the cake mix batter; pour into the prepared pan.
Bake according to the package instructions. Typically at 350 degrees F for 34 - 38 minutes. When a wooden toothpick inserted into the cake comes out clean, it is done.
Remove from the oven. Let cool to room temperature, about 30 minutes.
Filling:
Meanwhile, add the blueberries, condensed milk and lemon juice to a bowl. Using a potato masher or whisk, mash the blueberries into the condensed milk until well combined and only a few whole berries remain.
Using the handle end of a wooden spoon, poke holes across the top of the cake. Pour the blueberry mixture over the top to the edges, spreading to fill all of the holes.
Chill 2 hours.
Topping:
Add the cold heavy cream, cream cheese, powdered sugar and lemon zest to large bowl. Using a hand mixer, whip until still peaks form.
Spread the topping over the cake. Decorate with lemon slices.
