Ingredients for Lemon Blueberry Sheet Cake
Here is what you will need to make this delicious Lemon Blueberry Sheet Cake:
Easy, quick, delicious – and perfect for everything from summer BBQs to tasty snacks!
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 Tbs flour
– 2 1/2 cups powdered sugar
– 1/3 cup lemon juice
Instructions:
1. Preheat the oven to 350 degrees F. Grease a 9×13 baking dish, and line with parchment paper so there’s an overhang over the two long sides of the pan. This will make removing the cake much easier!
2. 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 hand mixer), cream together the sugar and butter until light and fluffy. Add the eggs and vanilla, and buttermilk, and mix on low until 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.
3. 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 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!
4. 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!

FAQs About Lemon Blueberry Sheet Cake
What is Lemon Blueberry Sheet Cake?
Lemon Blueberry Sheet Cake is a moist and flavorful dessert made with fresh blueberries and bright lemon juice, baked in a sheet pan for easy serving. It’s ideal for gatherings, picnics, or as a sweet treat at home. The combination of tart lemons with sweet blueberries creates a refreshing flavor profile that appeals to many palates.
How can I ensure my cake comes out fluffy?
To achieve a fluffy texture in your Lemon Blueberry Sheet Cake, make sure your butter is softened before creaming it with sugar until light and airy. Incorporate eggs one at a time and avoid over-mixing once you add the dry ingredients. These steps help create air pockets that result in a light crumb.
Can I use frozen blueberries instead of fresh ones?
Yes, you can use frozen blueberries if fresh ones are not available. However, it’s best to toss them in flour before adding them to the batter to prevent sinking during baking. Keep in mind that frozen blueberries may release more moisture, so adjust baking time accordingly if needed.
What should I do if my glaze is too thick?
If your glaze for the Lemon Blueberry Sheet Cake turns out too thick, simply add a small amount of additional lemon juice or water incrementally until you reach your desired consistency. A thinner glaze will allow it to drizzle beautifully over the cake while still providing that delicious lemon flavor.
