Ingredients
Easy, quick, delicious – and perfect for everything from summer BBQs to tasty snacks!
For the Cake
- 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 Tbs flour
For the Glaze
- 2 1/2 cups powdered sugar
- 1/3 cup lemon juice
How to Make Lemon Blueberry Sheet Cake
Step 1: Preheat the Oven
Preheat the oven to 350 degrees F. Grease a 9×13 baking dish and line it with parchment paper so there’s an overhang on the two long sides. This will make removing the cake much easier!
Step 2: Prepare the Batter
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 use a hand mixer), cream together the sugar and butter until light and fluffy.
Add in the eggs one at a time along with vanilla extract and buttermilk. Mix on low until everything is incorporated. Slowly add in the dry ingredients until no streaks of flour remain. Then mix in the lemon juice and zest. Gently stir in the blueberries using a spatula.
Step 3: Bake the Cake
Pour the batter into your prepared baking dish. Bake for about 40–45 minutes or until a toothpick inserted comes out with moist crumbs. Allow to cool completely before decorating.
Step 4: Add the Glaze
For the glaze, combine powdered sugar with lemon juice in a bowl until smooth. Pour over your cooled cake once it has cooled completely. Let it harden before garnishing with fresh fruit if desired.

How to Perfect Lemon Blueberry Sheet Cake
To achieve the best version of Lemon Blueberry Sheet Cake, follow these helpful tips. They will ensure your cake turns out moist and flavorful every time.
-
Use fresh blueberries: Fresh blueberries provide the best flavor and texture. Frozen ones can make the batter too wet.
-
Don’t overmix the batter: Mix just until combined; overmixing can lead to a tough cake.
-
Check doneness with a toothpick: Insert it into the center; it should come out clean or with a few moist crumbs, not wet batter.
-
Cool completely before glazing: Letting the cake cool allows the glaze to set properly and prevents it from sliding off.
-
Store properly: Keep leftovers in an airtight container at room temperature for up to three days for optimal freshness.
