Ingredients
Easy, quick, delicious – and perfect for everything from summer BBQs to tasty snacks!
Dry Ingredients
- 3 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 1/4 teaspoon salt
Wet Ingredients
- 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
Blueberries & Glaze
- 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 that 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 use a hand mixer), cream together the butter and sugar until light and fluffy. Add in the eggs one at a time along with vanilla extract and buttermilk; mix on low until incorporated. Gradually add dry ingredients until no streaks of flour remain. Finally, mix in lemon juice and zest before gently stirring in blueberries with a spatula.
Step 3: Bake the Cake
Pour the batter into your prepared baking dish. Bake for about 40-45 minutes or until a toothpick comes out with moist crumbs. Allow the cake to cool completely. You can lift it out of the pan before drizzling or leave it in the dish to serve.
Step 4: Prepare the Glaze
To make the glaze, combine powdered sugar with lemon juice in a bowl. Pour over the cooled cake once set. Let the glaze harden slightly before garnishing with fresh fruit.

How to Perfect Lemon Blueberry Sheet Cake
Perfecting your Lemon Blueberry Sheet Cake can elevate it to the next level. Here are some helpful tips to ensure success.
- Measure Ingredients Accurately: Precision in measuring flour and sugar helps achieve the right texture and flavor balance.
- Use Room Temperature Ingredients: Ensuring butter, eggs, and buttermilk are at room temperature aids in proper mixing and results in a fluffier cake.
- Don’t Overmix: Mix until the ingredients are just combined to avoid a dense cake. Overmixing can lead to gluten development.
- Check Oven Temperature: An oven thermometer ensures correct baking temperatures. An overly hot oven may cause uneven baking.
- Cool Completely Before Glazing: Allow the cake to cool fully before adding the glaze; this prevents melting and ensures a beautiful finish.
- Store Properly: Keep leftovers in an airtight container at room temperature or refrigerate to maintain freshness for several days.
Best Side Dishes for Lemon Blueberry Sheet Cake
When serving Lemon Blueberry Sheet Cake, consider pairing it with these delightful side dishes for an enhanced dining experience.
- Fruit Salad: A mix of seasonal fruits provides a refreshing contrast to the sweetness of the cake.
- Green Salad: A simple green salad with vinaigrette offers a nice balance of flavors and textures.
- Cheese Platter: A selection of mild cheeses pairs well with the cake’s bright flavors, offering savory bites alongside sweet ones.
- Yogurt Parfait: Layered yogurt with granola and fruit makes for an excellent breakfast option or light snack alongside dessert.
- Honeyed Nuts: Sweetened nuts add crunch and depth, making them an enjoyable complement to the moist cake.
- Chilled Tea: Iced herbal tea or mint tea enhances the refreshment factor while providing a soothing drink option.
Common Mistakes to Avoid
Baking a Lemon Blueberry Sheet Cake can be a delightful experience, but it’s easy to make mistakes. Here are some common pitfalls to watch out for:
- Using cold ingredients: Always ensure your butter and eggs are at room temperature for a smoother batter and better rise.
- Not measuring flour correctly: Use the spoon-and-level method to avoid adding too much flour, which can lead to a dense cake.
- Overmixing the batter: Mix just until combined. Overmixing can develop gluten and make the cake tough.
- Ignoring baking time: Check for doneness with a toothpick around the 40-minute mark; every oven is different, and this ensures a perfectly baked cake.
- Skipping the glaze: The lemon glaze adds moisture and flavor—don’t skip it!
