Lemon Blueberry Sheet Cake
Lemon blueberry sheet cake is a crowd pleasing dessert made with boxed lemon cake mix and fresh blueberries baked and topped with a sweet lemon glaze.
Ingredients
- 1 Box Lemon Cake Mix (plus the ingredients to make it)
- 1 Cup Blueberries
- 1 Tbs Flour
- 1 Cup Powdered Sugar
- 2-3 Tbs Lemon Juice
- 1 Lemon, zested
Instructions
- In a large bowl, stir together the lemon cake mix and all of the ingredients to make it.
- In a small bowl, toss the blueberries in the little flour. This is supposed to help the blueberries from sinking to the bottom of the cake. Most of mine still sunk, but maybe you'll have better luck.
- Fold the blueberries into the cake batter.
- Line a 9 x 13" baking dish with parchment paper, leaving the sides long. That will make it easier to pull the cake out later.
- Pour the cake batter into the parchment paper lined baking dish and smooth it out so that it's flat and even.
- Bake it in the oven according to the directions on the back of the cake mix package.
- In the meantime, mix together the powdered sugar and lemon juice until it's evenly combined.
- Once the cake is fully baked and still warm, pour the lemon glaze on top. Using the back of a spoon, spread it out evenly.
- Garnish with more blueberries and lemon zest. Place it into the refrigerator to let it cool completely.
- Use the long pieces of parchment paper to pull the cake out of the baking dish.
- Finally, cut the cake into squares and enjoy!
