Ingredients
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
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, then line it with parchment paper. Ensure there’s an overhang on the two long sides of the pan. 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 using a hand mixer), cream together the sugar and butter until light and fluffy.
Add the eggs, vanilla extract, and buttermilk; mix on low speed until fully incorporated. Gradually add the dry ingredients until no streaks of flour remain. Finally, mix in the lemon juice and zest. Gently fold in the blueberries using a spatula.
Step 3: Bake the Cake
Pour the cake batter into your prepared baking dish. Bake for about 40–45 minutes or until a toothpick inserted into the center comes out with moist crumbs. Allow it to cool completely. You can lift the cake out of the pan before glazing or leave it in the dish to serve.
Step 4: Add the Glaze
For the glaze, combine powdered sugar and lemon juice in a bowl until smooth. Pour over the cooled cake once it has set slightly. Let it harden before garnishing with fresh fruit if desired, then serve!

How to Perfect Lemon Blueberry Sheet Cake
To ensure your Lemon Blueberry Sheet Cake turns out perfectly every time, consider these helpful tips.
-
Room Temperature Ingredients: Use eggs and butter at room temperature for better mixing, which results in a fluffier cake.
-
Don’t Overmix: Mix just until combined when adding dry ingredients to prevent a dense texture.
-
Toss Blueberries in Flour: Coat blueberries in flour before adding them to the batter. This helps prevent them from sinking during baking.
-
Test for Doneness: Insert a toothpick into the center; it should come out with moist crumbs, not wet batter.
-
Cool Completely: Allow the cake to cool completely before applying the glaze for the best texture and flavor absorption.
-
Store Properly: Keep any leftovers in an airtight container at room temperature for up to three days to maintain freshness.
Best Side Dishes for Lemon Blueberry Sheet Cake
Pairing side dishes with your Lemon Blueberry Sheet Cake can enhance the overall experience. Here are some great options that complement its flavors well.
-
Fruit Salad: A mix of seasonal fruits such as strawberries, kiwi, and melons adds freshness.
-
Cheese Platter: Serve with a selection of soft cheeses like brie or goat cheese for a creamy contrast.
-
Popsicles: Homemade lemon or blueberry popsicles make for a fun, refreshing side.
-
Yogurt Parfait: Layer yogurt with granola and berries for a deliciously creamy accompaniment.
-
Savory Scones: Pair with lemon-infused scones for an unexpected savory touch.
-
Sparkling Water: Offer sparkling water with lemon slices as a light beverage option that enhances the citrus notes of the cake.
-
Chocolate-Covered Strawberries: These provide a sweet and slightly tart bite that complements the cake beautifully.
-
Mint Tea: A chilled mint tea can refresh your palate after enjoying this rich dessert.
Common Mistakes to Avoid
Baking a Lemon Blueberry Sheet Cake can be simple, but there are common pitfalls to watch out for. Here are some mistakes to avoid:
- Using cold ingredients: Always use room temperature eggs and butter. Cold ingredients can cause the batter to not mix evenly, affecting the cake’s texture.
- Overmixing the batter: Mixing too much can lead to a dense cake. Stop mixing as soon as you no longer see dry flour.
- Not measuring flour correctly: Use the spoon-and-level method for accurate flour measurement. Scooping directly from the bag can pack the flour and alter the recipe.
- Skipping the parchment paper: This makes removing the cake easier. If you skip it, your cake may stick to the pan, making it difficult to serve.
- Ignoring cooling time: Letting the cake cool completely before glazing is essential. Otherwise, the glaze will melt off instead of setting nicely.

Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- Keep the cake at room temperature for up to 2 days if covered.
Freezing Lemon Blueberry Sheet Cake
- Wrap tightly in plastic wrap and then in aluminum foil.
