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, allowing some overhang on the two long sides. This will help you lift the cake out easily once it’s baked.
Step 2: Prepare the Batter
In a medium mixing bowl, whisk together the dry ingredients: flour through salt. Set aside. In your stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the sugar and butter until light and fluffy.
Next:
1. Add the eggs one at a time, mixing well after each addition.
2. Pour in the vanilla extract and buttermilk, mixing on low until fully incorporated.
3. Gradually add in the dry ingredient mixture until no streaks of flour remain.
4. Mix in the lemon juice and zest gently.
5. Finally, 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 comes out with moist crumbs. Allow the cake to cool completely; you can either lift it out of the pan before drizzling with glaze or leave it in the dish.
Step 4: Add the Glaze
For the glaze, combine powdered sugar and lemon juice until smooth. Drizzle over the cooled cake and let it harden slightly before garnishing with fresh fruit. Serve and enjoy!

Alongside Vanilla Ice Cream

Garnished with Extra Berries
- Add fresh blueberries or raspberries on top as a garnish. This not only looks appealing but also adds an extra burst of fruity flavor.

How to Perfect Lemon Blueberry Sheet Cake
To achieve the best results with your Lemon Blueberry Sheet Cake, keep these tips in mind.
-
Use fresh ingredients: Fresh lemons and blueberries enhance the flavor profile. Ensure they are ripe for optimal taste.
-
Don’t overmix the batter: Mix just until combined to keep the cake tender and fluffy. Overmixing can lead to a dense texture.
-
Check for doneness: Use a toothpick to test if the cake is done. Look for moist crumbs rather than wet batter to ensure it’s baked perfectly.
-
Cool completely before glazing: Allowing the cake to cool ensures that the glaze sets properly without melting into the cake.
-
Adjust sweetness as desired: If you prefer less sweetness, reduce the powdered sugar in the glaze slightly without compromising consistency.
-
Store properly: Keep leftover cake covered at room temperature or in the fridge for freshness, ensuring it stays moist and delicious.
Best Side Dishes for Lemon Blueberry Sheet Cake
Pairing side dishes with your Lemon Blueberry Sheet Cake can elevate your dessert experience. Here are some great options:
-
Citrus Salad: A light salad featuring mixed greens, oranges, and grapefruit segments creates a refreshing balance to the sweetness of the cake.
-
Charcuterie Board: Offer a selection of cheeses, nuts, and fruits alongside the cake for guests who enjoy savory flavors with their dessert.
-
Chocolate-Dipped Strawberries: The rich chocolate contrasts beautifully with the tartness of lemon, making this pairing delightful.
-
Lemon Sorbet: A chilled sorbet brings additional lemon flavor while cleansing the palate between bites of cake.
-
Fruit Compote: Serve a warm fruit compote made from seasonal fruits over each slice for added moisture and flavor enhancement.
-
Pistachio Muffins: These nutty muffins add texture and richness that complements the lightness of Lemon Blueberry Sheet Cake.

Common Mistakes to Avoid
When baking your Lemon Blueberry Sheet Cake, a few pitfalls can lead to less-than-perfect results. Here are some common mistakes and how to sidestep them.
-
measurement errors: Accurate measurements are crucial. Using too much flour or sugar can alter the cake’s texture. Always use measuring cups and spoons for precise measurements.
-
overmixing the batter: Mixing too much can make your cake tough. After adding the dry ingredients, mix until just combined for a light and fluffy texture.
-
skipping the parchment paper: Not lining your baking dish can result in a sticky situation. Always use parchment paper for easy removal of the cake after baking.
-
ignoring cooling time: Cutting into the cake before it cools can make it crumbly. Allow your Lemon Blueberry Sheet Cake to cool completely for the best results.
-
using stale ingredients: Fresh ingredients, especially baking powder and blueberries, are key. Check expiration dates to ensure your cake rises perfectly and tastes fresh.
