Ingredients
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 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!
Step 2: Prepare the Batter
In a medium mixing bowl, whisk together the dry ingredients: flour, baking powder, baking soda, and salt. Set aside. In a stand mixer fitted with the paddle attachment (or use a hand mixer), cream together sugar and butter until light and fluffy. Add eggs, vanilla, and buttermilk, mixing on low until incorporated. Add the dry ingredients, mixing until no streaks of flour remain. Mix in lemon juice and zest. Gently stir in blueberries with a spatula.
Step 3: Bake
Pour the cake batter into the prepared baking dish. 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!
Step 4: Make the Glaze
For the glaze, combine powdered sugar and lemon juice. Pour over the cooled cake. Let the glaze harden before garnishing with fresh fruit and serving!

How to Perfect Lemon Blueberry Sheet Cake
To ensure your Lemon Blueberry Sheet Cake turns out perfectly every time, follow these helpful tips.
- Choose Fresh Blueberries: Using fresh blueberries enhances flavor and texture. Frozen berries can make the batter soggy.
- Room Temperature Ingredients: Let your butter, eggs, and buttermilk reach room temperature before mixing for better incorporation.
- Don’t Overmix: Mix until just combined; overmixing can lead to a dense cake. The batter should be slightly lumpy.
- Check Oven Temperature: Use an oven thermometer to confirm accurate temperatures. This helps achieve even baking.
- Cool Completely Before Glazing: Allow the cake to cool completely before adding glaze, preventing it from melting away.
- Experiment with Zest: Adjust the amount of lemon zest to suit your taste—more zest equals more flavor!
Best Side Dishes for Lemon Blueberry Sheet Cake
When serving Lemon Blueberry Sheet Cake, consider these delicious side dishes that pair well and enhance its flavors.
- Greek Yogurt Parfait: Layer Greek yogurt with granola and fruits for a creamy and crunchy side that complements the cake.
- Cucumber Salad: A light cucumber salad dressed in vinegar adds a refreshing crunch that balances sweetness.
- Pasta Salad: A cold pasta salad with herbs and veggies offers great texture contrast and makes for a hearty meal option.
- Caprese Skewers: Cherry tomatoes, mozzarella balls, and basil drizzled with balsamic reduction provide fresh bursts of flavor.
- Cheese Board: Include assorted cheeses and nuts for guests who enjoy savory bites alongside their sweet dessert.
- Berry Smoothie: Blend a berry smoothie as a refreshing beverage that echoes the flavors of the cake while cooling off guests.
Common Mistakes to Avoid
Avoiding common mistakes can make your Lemon Blueberry Sheet Cake even more delightful. Here are some pitfalls to watch out for:
- Overmixing the batter: Overmixing can lead to a dense cake. Mix just until the ingredients are combined for a light and fluffy texture.
- Using cold ingredients: Cold butter or eggs can affect how well they incorporate into the batter. Always use room temperature ingredients for best results.
- Not measuring flour correctly: Scooping flour directly from the bag can pack it down, leading to too much flour in the recipe. Use the spoon-and-level method for accurate measurement.
- Skipping the parchment paper: Not lining your baking dish with parchment paper can make it difficult to remove the cake later. Always line your pan for easy lifting and serving.
- Ignoring cooling time: Drizzling glaze on a warm cake can cause it to melt away. Ensure your cake is completely cool before adding any glaze.
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- Place parchment paper between layers if stacking to prevent sticking.
Freezing Lemon Blueberry Sheet Cake
- Wrap tightly in plastic wrap and then foil for up to 3 months.
- Thaw overnight in the refrigerator before serving.
Reheating Lemon Blueberry Sheet Cake
- Oven: Preheat to 350°F and warm slices wrapped in foil for about 10-15 minutes.
- Microwave: Heat individual slices for about 15-20 seconds until warm.
- Stovetop: Use a non-stick skillet over low heat, cover, and warm for about 5 minutes.
