Step-by-Step Preparation of Lemon-Blueberry Sheet Cake
Baking a Lemon-Blueberry Sheet Cake is a delightful experience that fills your kitchen with an invigorating aroma, perfect for any gathering. Let’s break down the steps to ensure your cake comes out moist, flavorful, and utterly delicious.
Gather and prepare your ingredients
Before diving into the world of baking, it's essential to gather and prepare your ingredients. You’ll need the following:
- 2 ¾ cups all-purpose flour
- 2 tsp. baking powder
- ¼ tsp. baking soda
- ½ tsp. kosher salt
- 2 cups granulated sugar
- 2 Tbsp. grated lemon zest
- ⅓ cup fresh lemon juice (from about 2 to 3 lemons)
- 3 large eggs (at room temperature)
- 1 cup vegetable oil
- 2 tsp. vanilla extract
- ½ tsp. lemon extract
- ¾ cup buttermilk (at room temperature)
- Cooking spray for the pan
Make sure your eggs and buttermilk are at room temperature for a smoother batter. Lay all your ingredients out on the counter so you can grab them easily.
Mix the dry ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and kosher salt. It’s vital to aerate the flour and break up any lumps — this helps the cake rise beautifully. For more tips on mixing dry ingredients, check out this baking guide.
Combine the wet ingredients
In a large mixing bowl, combine your granulated sugar and lemon zest. Use your fingers to rub the zest into the sugar — this step releases the essential oils, intensifying the lemon flavor. Add the eggs and whisk until the mixture becomes foamy and light in color, which usually takes about 1 to 2 minutes. Then, mix in the vegetable oil, vanilla extract, lemon extract, and fresh lemon juice.
Create the batter and prepare the pan
Gradually stir in your dry ingredient mixture, alternating with the buttermilk. Mix well after each addition until you have a smooth, lump-free batter. Next, preheat your oven to 350°F and prepare a 13-by-18-inch rimmed baking sheet by spraying it with cooking spray. Pour the batter into the pan, ensuring an even spread.
Bake to perfection
Slide your cake into the preheated oven and bake for 16 to 18 minutes. It's essential to rotate the pan halfway through baking for even cooking. The cake is ready when it's lightly golden and a toothpick inserted into the center comes out clean. Allow it to cool completely in the pan on a rack for at least an hour.
Prepare the frosting while the cake cools
While the cake is cooling, it’s time to whip up the frosting. In a stand mixer, beat 2 sticks of room-temperature salted butter until it’s fluffy. You can add powdered sugar and lemon juice to create a tangy frosting that complements the cake beautifully.
Frost and let it set
Once your cake has cooled, spread the frosting over the top evenly. For an extra touch, sprinkle fresh blueberries on top or drizzle with additional lemon glaze. Let the frosting set for about 15 minutes before serving.
And there you have it — a beautiful Lemon-Blueberry Sheet Cake that's sure to impress your family and friends! Enjoy every delicious bite and revel in the fresh flavors!

Variations on Lemon-Blueberry Sheet Cake
Lemon-Blueberry with a Twist: Adding Herbs

Plus, herbs like basil or mint could pair beautifully with the citrus and berries, adding a refreshing contrast.
Gluten-Free Version
For those seeking a gluten-free option, fear not! You can easily substitute the all-purpose flour with a gluten-free flour blend, ensuring it’s one that includes xanthan gum for the right texture. Make sure to double-check your baking powder is also gluten-free. This way, you can enjoy a delicious slice of Lemon-Blueberry Sheet Cake without any worries.

Cooking Tips and Notes for Lemon-Blueberry Sheet Cake
Tips for achieving the perfect texture
For a moist and airy Lemon-Blueberry Sheet Cake, start with room-temperature eggs and buttermilk—it truly makes a difference! Ensure you don’t overmix once you combine the wet and dry ingredients; gentle folding retains that desired fluffiness. And don’t forget to rotate the baking sheet halfway through to ensure even baking.
Common mistakes to avoid
Avoid adding blueberries directly to the batter, as they can sink to the bottom. Instead, toss them in a bit of flour first to help them stay suspended throughout the cake. Be cautious with oven temperature; investing in an oven thermometer can ensure accurate baking—helpful for new bakers looking to achieve that perfect cake texture.
