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)

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 so there’s an overhang on the two long sides of the pan. This will make removing the cake much easier!
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together the dry ingredients—flour through salt. Set aside.
Step 3: Cream Butter and Sugar
In a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the sugar and butter until light and fluffy.
Step 4: Add Wet Ingredients
Add the eggs, vanilla, and buttermilk to the mixture. Mix on low until everything is well incorporated.
Step 5: Combine Dry Ingredients
Gradually add in the dry ingredients while mixing until no streaks of flour remain. Mix in lemon juice and zest until fully combined.
Step 6: Fold in Blueberries
Gently stir in the blueberries using a spatula to avoid crushing them.
Step 7: Bake
Pour the cake batter into your prepared baking dish. Bake for about 40-45 minutes or until a toothpick inserted comes out with moist crumbs. Allow cooling completely.
Step 8: Prepare the Glaze
For the glaze, combine powdered sugar with lemon juice. Pour over the cooled cake once it’s set.
Step 9: Serve
Let the glaze harden before garnishing with fresh fruit if desired. Slice into squares and serve!

How to Perfect Lemon Blueberry Sheet Cake
Getting your Lemon Blueberry Sheet Cake just right is easy with these helpful tips. Follow them for the best results every time!
- Use room temperature ingredients: Make sure your butter, eggs, and buttermilk are at room temperature for better mixing and texture.
- Don’t overmix: Gently fold in the dry ingredients and blueberries to maintain a tender crumb.
- Check for doneness: Insert a toothpick into the center; it should come out with moist crumbs, not wet batter.
- Cool completely before glazing: Letting the cake cool ensures that the glaze sets nicely without running off.
- Store properly: Keep leftovers in an airtight container at room temperature for up to three days to maintain freshness.
- Experiment with add-ins: Consider adding lemon zest or even poppy seeds for an exciting twist on this classic recipe.
Best Side Dishes for Lemon Blueberry Sheet Cake
Pairing side dishes with your Lemon Blueberry Sheet Cake can create a balanced meal or snack. Here are some great options:
- Yogurt Parfait: Layer Greek yogurt with granola and fresh berries for a creamy, crunchy contrast.
- Fruit Salad: A mix of seasonal fruits like melon, kiwi, and berries adds freshness to your dessert spread.
- Cheese Platter: Offer assorted cheeses, such as creamy brie or sharp cheddar, which pair surprisingly well with sweet cakes.
- Savory Scones: Serve savory herb scones on the side to balance the sweetness of the cake.
- Mixed Nuts: A bowl of spiced mixed nuts provides crunch and richness that complements the soft cake.
- Iced Tea or Lemonade: Refreshing beverages like iced tea or homemade lemonade enhance the lemony flavor profile beautifully.
- Whipped Cream: A dollop of freshly whipped cream can add lightness and softness to each bite.
- Chocolate Dipped Strawberries: These are always a hit and provide an elegant touch alongside your dessert!
Common Mistakes to Avoid
Making a Lemon Blueberry Sheet Cake can be simple, but there are a few common mistakes that can lead to less-than-perfect results.
- Using cold ingredients: Make sure your butter and eggs are at room temperature. This helps to create a smooth batter and ensures even baking.
- Overmixing the batter: Mixing too much after adding the flour can make your cake dense. Mix just until combined for a light and fluffy texture.
- Not measuring accurately: Use proper measuring tools for dry and wet ingredients. Too much flour or too little sugar can affect the flavor and texture.
- Skipping the lemon zest: The zest adds essential flavor. Don’t skip it; instead, use a microplane to get the most out of your lemons.
- Ignoring baking time: Every oven is different. Start checking your cake a few minutes early to avoid overbaking, which can lead to a dry cake.
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- If covered with glaze, it’s best consumed within 2-3 days for optimal freshness.
Freezing Lemon Blueberry Sheet Cake
- Wrap tightly in plastic wrap, then in aluminum foil for up to 3 months.
- For best results, freeze before glazing. Thaw in the refrigerator overnight before serving.
Reheating Lemon Blueberry Sheet Cake
- Oven: Preheat to 350°F, cover with foil, and heat for about 10-15 minutes until warmed through.
- Microwave: Heat individual slices on medium power for about 30 seconds or until warm.
- Stovetop: Place slices in a skillet over low heat, cover, and warm for about 5 minutes.
