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 your oven to 350 degrees F. Grease a 9×13 baking dish and line it with parchment paper. Make sure there’s an overhang on two long sides; this will help you lift the cake out easily later.
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together your dry ingredients: flour, baking powder, baking soda, and salt. Set aside while you prepare the wet mixture.
Step 3: Cream Butter and Sugar
In a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the granulated sugar and softened butter until it becomes light and fluffy.
Step 4: Add Wet Ingredients
Add in the eggs one at a time along with vanilla extract and buttermilk. Mix on low speed until everything is incorporated smoothly.
Step 5: Combine Mixtures
Gradually add your dry ingredients into the wet mixture. Mix until there are no streaks of flour left. Then mix in the lemon juice and zest before gently folding in the blueberries with a spatula.
Step 6: Bake
Pour your batter into the prepared baking dish. Bake for about 40-45 minutes or until a toothpick inserted comes out with moist crumbs attached. Allow it to cool completely once done.
Step 7: Prepare Glaze
For the glaze, combine powdered sugar with lemon juice in a bowl until smooth. Drizzle over your cooled cake. Let it set before garnishing with fresh fruit if desired.
Enjoy this delightful Lemon Blueberry Sheet Cake as an irresistible dessert that brings joy to every occasion!

How to Perfect Lemon Blueberry Sheet Cake
To ensure your Lemon Blueberry Sheet Cake turns out perfectly every time, consider these essential tips. A few adjustments can make all the difference in taste and texture.
-
Use room temperature ingredients – Make sure your butter, eggs, and buttermilk are at room temperature. This helps them blend more easily into the batter.
-
Don’t overmix the batter – Mix just until combined to avoid a dense cake. Gentle mixing keeps the cake light and fluffy.
-
Measure flour correctly – Spoon flour into your measuring cup without packing it down. This ensures you don’t use too much flour, which can lead to a dry cake.
-
Check doneness early – Start testing your cake at around 35 minutes. Every oven is different, so it’s best not to overbake.
-
Cool completely before glazing – Allowing the cake to cool fully prevents the glaze from melting away into the warm cake, ensuring it stays intact.
Best Side Dishes for Lemon Blueberry Sheet Cake
Pairing side dishes with your Lemon Blueberry Sheet Cake can enhance its enjoyment during any occasion. Here are some great options that complement its flavors beautifully.
- Lemon Sorbet – A light and refreshing dessert that pairs nicely with the lemony notes in the sheet cake.
- Coconut Macaroons – Chewy and sweet, these cookies provide a delightful contrast in texture.
- Minted Fruit Salad – A mix of seasonal fruits tossed with mint adds freshness and balances sweetness.
- Chocolate Mousse – Rich and creamy chocolate mousse creates an indulgent combination when served alongside the citrusy cake.
- Almond Biscotti – Crunchy and nutty biscotti offers a satisfying bite paired with coffee or tea after dessert.
- Pineapple Upside-Down Cake – For those who love layered flavors, this classic dessert provides another sweet option that’s still fruity.
- Cheese Platter – A selection of mild cheeses can balance the sweetness while providing savory contrasts.
Common Mistakes to Avoid
When making your Lemon Blueberry Sheet Cake, it’s easy to make a few common mistakes. Avoiding these can lead to a more successful baking experience.
- Not measuring ingredients correctly: Accurate measurements are key for baking. Use dry measuring cups for flour and sugar and liquid measuring cups for wet ingredients.
- Skipping the room temperature step: Cold butter and eggs can affect the cake’s texture. Let them sit out for about 30 minutes before starting your recipe.
- Overmixing the batter: Overmixing can lead to a dense cake. Mix just until combined to keep your Lemon Blueberry Sheet Cake light and fluffy.
- Not preparing the pan properly: Failing to grease and line your baking dish can result in sticking. Use parchment paper and non-stick spray for easy removal.
- Ignoring bake time: Ovens can vary in temperature. Start checking for doneness a few minutes early by inserting a toothpick into the center of the cake.

- Store leftover Lemon Blueberry Sheet Cake in an airtight container.
