How to Make Lemon Blueberry Sheet Cake
Ingredients
- 3 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 1/4 teaspoon salt
- 1 cup butter (2 sticks), softened
- 1 1/2 cups granulated sugar
- Juice and zest of 2 lemons (about 1/4 cup lemon juice)
- 4 large eggs
- 1 cup buttermilk
- 2 teaspoons vanilla extract
- 1 1/2 cups fresh blueberries, tossed with 1 tablespoon flour
- 2 1/2 cups powdered sugar
- 1/3 cup lemon juice
Directions
- Preheat the oven to 350 degrees F. Grease a 9×13 baking dish and line it with parchment paper so there’s an overhang over the two long sides of the pan. This will make removing the cake much easier!
- In a medium mixing bowl, whisk together the dry ingredients: flour through salt. Set aside.
- In a stand mixer fitted with the paddle attachment (or a hand mixer), cream together the sugar and butter until light and fluffy.
- Add the eggs, vanilla, and buttermilk, and mix on low until everything is incorporated.
- Add the dry ingredients and mix until no streaks of flour remain. Mix in the lemon juice and zest.
- Gently stir in the blueberries with a spatula.
- Pour the cake batter into the prepared 9×13 baking dish and bake for about 40-45 minutes, or until a toothpick comes out with moist crumbs.
- Allow the cake to cool completely. You can lift the cake out of the pan before drizzling, or leave it in the dish to serve. Either way works!
- For the glaze: combine the powdered sugar and lemon juice, and pour over the cooled cake. Let the glaze harden, and then garnish with fresh fruit and serve!
