Ingredients

Easy, quick, delicious – and perfect for everything from summer BBQs to tasty snacks!

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 your oven to 350 degrees F. Grease a 9×13 baking dish and line it with parchment paper. Ensure there’s an overhang on the two long sides; this helps remove the cake easily later on.

Step 2: Prepare the Batter

In a medium mixing bowl:
Whisk together the dry ingredients—flour through salt—and set aside.
In a stand mixer fitted with the paddle attachment (or use a hand mixer):
Cream together the granulated sugar and softened butter until light and fluffy.
Add in the eggs, vanilla extract, and buttermilk. Mix on low speed until well incorporated.
Gradually add the dry ingredients. Mix until no streaks of flour remain.
Stir in lemon juice and zest before gently folding in the blueberries using a spatula.

Step 3: Bake Your Cake

Pour the batter into your prepared baking dish.
Bake for about 40-45 minutes or until a toothpick inserted comes out with moist crumbs.
Allow your cake to cool completely before serving. You can lift it out of the pan before drizzling glaze or leave it in the dish.

Step 4: Make and Add Glaze

For the glaze:
Combine powdered sugar with lemon juice until smooth.
Pour this mixture over your cooled cake. Let it set before garnishing with fresh fruit if desired.

Now you’re ready to enjoy your delightful Lemon Blueberry Sheet Cake, perfect for any gathering!

How to Serve Lemon Blueberry Sheet Cake

Lemon Blueberry Sheet Cake is a delightful dessert that can be enjoyed in various ways. Whether you’re at a summer picnic or hosting a family gathering, this cake is sure to impress. Here are some serving suggestions to elevate your cake experience.

Classic Slice

Serve generous slices of the cake on individual plates for a traditional presentation. Pair with a dollop of whipped cream for added richness.

Fresh Berries Topping

Top each piece with fresh blueberries or raspberries. This adds an extra burst of flavor and enhances the visual appeal.

Lemon Zest Garnish

Grate some lemon zest over each slice before serving. This will amplify the citrus flavor and provide a beautiful finish.

Ice Cream Delight

Serve warm slices with a scoop of vanilla ice cream. The cold ice cream complements the warmth of the cake perfectly.

Lemon Glaze Drizzle

For an extra zing, drizzle additional lemon glaze on top just before serving. It enhances the sweetness while keeping it refreshing.

Afternoon Tea Pairing

Cut the cake into smaller squares and serve alongside tea. This makes for a delightful afternoon treat.

How to Perfect Lemon Blueberry Sheet Cake

To ensure your Lemon Blueberry Sheet Cake turns out perfectly every time, consider these helpful tips.

Use Room Temperature Ingredients: Allow butter, eggs, and buttermilk to reach room temperature before mixing. This helps create a smoother batter and ensures even baking.
Don’t Overmix: When combining wet and dry ingredients, mix just until no flour streaks remain. Overmixing can lead to a dense cake texture.
Check Oven Temperature: Use an oven thermometer to ensure your oven is at the correct temperature. An inaccurate oven can lead to undercooked or burnt cake.
Cool Completely Before Glazing: Let the cake cool fully before adding the glaze. This prevents it from melting into the cake and ensures a nice finish.

Best Side Dishes for Lemon Blueberry Sheet Cake

Pairing side dishes with your Lemon Blueberry Sheet Cake can enhance your dessert experience. Here are some great options that complement its flavors well.

Citrus Salad: A light salad with mixed greens, oranges, and a citrus vinaigrette refreshes the palate.
Minted Fruit Salad: Combine seasonal fruits with fresh mint for a sweet, tangy side that balances the cake’s richness.
Yogurt Parfait: Layer yogurt with granola and more blueberries for a creamy contrast to the cake.
Cheese Platter: Offer an assortment of cheeses like brie or goat cheese that pair nicely with lemon flavors.
Herbed Couscous: A light couscous salad with herbs adds an interesting texture and flavor profile alongside your cake.
Pistachio Baklava: The nutty sweetness of baklava complements the bright lemon notes in your sheet cake beautifully.
Spiced Nuts: A bowl of spiced nuts provides crunchy contrast and balances out the sweetness of the dessert.
Chocolate Dipped Strawberries: These classic treats add decadence and work wonderfully alongside fruity desserts like this cake.

Common Mistakes to Avoid

Baking a Lemon Blueberry Sheet Cake can seem simple, but there are common pitfalls. Here are some mistakes to avoid:

Not Measuring Ingredients Accurately: Baking is a science. Use proper measuring cups and spoons to ensure you have the right quantities for a successful cake.
Overmixing the Batter: Mixing too much can lead to a dense cake. Mix just until combined to keep your cake light and airy.
Skipping the Lemon Zest: The zest adds essential flavor. Don’t skip it; it elevates the taste of your Lemon Blueberry Sheet Cake significantly.
Not Prepping Your Pan Properly: Greasing and lining your pan is crucial. Make sure to do this step well so that your cake comes out easily after baking.
