Step‑by‑Step Instructions for Lemon Blueberry Sheet Cake
Step 1: Preheat the Oven and Prepare the Pan
Preheat your oven to 350°F (175°C) while you prepare a 9×13-inch sheet pan. Use cooking spray or line the pan with parchment paper, ensuring it covers the bottom and sides. This step is essential to prevent sticking and will give your Lemon Blueberry Sheet Cake a beautiful, clean edge when it’s finished baking.
Step 2: Prepare the Lemons
Zest two lemons using a microplane or a fine grater, collecting the bright, fragrant yellow zest in a small bowl. Then, roll the lemons on the countertop to release more juice, and juice them until you have ¼ cup of fresh lemon juice. Set both the zest and juice aside; they will add that zesty flavor to your cake.
Step 3: Coat the Blueberries
In a small bowl, toss the fresh blueberries with a tablespoon of flour until they are evenly coated. This simple technique helps to prevent the blueberries from sinking during baking, ensuring that your Lemon Blueberry Sheet Cake has pockets of delicious fruit throughout.
Step 4: Mix the Dry Ingredients
In a separate mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This step is crucial for evenly distributing the leavening agents throughout the flour, which will provide an even rise and fluffiness to your cake. Set the dry ingredients aside while you work on the wet mixture.
Step 5: Cream the Butter and Sugar
In your mixing bowl, add the softened butter and granulated sugar. Using an electric mixer, beat them together on medium speed for about 3-5 minutes until the mixture is light, fluffy, and pale in color. This step incorporates air into the batter, contributing to the moist texture of the Lemon Blueberry Sheet Cake.
Step 6: Add Eggs and Flavorings
With the mixer on low speed, add the eggs one at a time, allowing each to incorporate fully before adding the next. After the eggs, mix in the lemon zest and vanilla extract until just combined. This infusion of flavor is what will make your cake fragrant and delicious, enhancing the overall taste.
Step 7: Combine Dry Ingredients and Buttermilk
Gradually add the dry ingredient mixture to the butter mixture, alternating with the buttermilk. Start and end with the dry ingredients, mixing gently until just combined. Be careful not to overmix; you want a moist cake crumb for your Lemon Blueberry Sheet Cake, so it should still appear slightly lumpy.
Step 8: Fold in Blueberries
Using a rubber spatula, gently fold the flour-coated blueberries into the batter until evenly distributed. This step ensures that every bite of your Lemon Blueberry Sheet Cake is bursting with sweet blueberries while maintaining the integrity of the batter.
Step 9: Bake the Cake
Pour the batter into your prepared sheet pan, smoothing out the top with a spatula. Bake in the preheated oven for 35-40 minutes or until a toothpick inserted in the center comes out clean with a few moist crumbs. Keep an eye on the cake towards the end to avoid overbaking, which can dry it out.
Step 10: Cool Before Glazing
Once baked, remove the pan from the oven and let the Lemon Blueberry Sheet Cake cool in the pan for about 10-15 minutes. Then, carefully transfer it to a wire rack to cool completely before glazing. Cooling prevents the glaze from melting into the warm cake, ensuring a beautiful finish.
Step 11: Prepare the Lemon Glaze
In a mixing bowl, whisk together the powdered sugar and the remaining lemon juice until smooth and glossy. This glaze will be drizzled over the cooled cake, enhancing its flavor and providing that delightful citrus hit that makes your Lemon Blueberry Sheet Cake truly shine.
Step 12: Drizzle and Garnish
Once the cake is completely cool, drizzle the lemon glaze over the top evenly. For an extra touch, sprinkle some additional lemon zest on top. This final step not only elevates the visual appeal but also packs a punch of zesty flavor that complements the moist cake and bursts of blueberries perfectly.

Make Ahead Options
These Lemon Blueberry Sheet Cake are perfect for busy home cooks who appreciate meal prep!

How to Store and Freeze Lemon Blueberry Sheet Cake
Room Temperature: Keep the cake covered at room temperature for up to 2 days. This maintains its moisture and softness, allowing you to enjoy the fresh flavors.
Fridge: Store the cake in an airtight container in the fridge for up to 4 days. This method helps preserve the tangy flavors of the lemon while keeping the cake moist.
Reheating: If desired, lightly reheat individual slices in the microwave for about 10-15 seconds. This will warm the cake and restore that fresh-baked feel without compromising its texture.
Freezer: Avoid freezing the Lemon Blueberry Sheet Cake to prevent changes in texture. The delicate crumb may become dry and lose its moist quality once thawed.

Lemon Blueberry Sheet Cake Recipe FAQs
How do I select ripe blueberries for the cake?
Absolutely! When picking blueberries, look for those that are plump, firm, and have a deep blue hue. Avoid any berries with green or red spots, as they may be under-ripe. Fresh blueberries will also have a slight bloom on their skin, indicating they’re at their best. Always give them a gentle squeeze; if they yield slightly without being mushy, they’re perfect for your cake!
What is the best way to store leftover Lemon Blueberry Sheet Cake?
You can keep your cake covered at room temperature for up to 2 days to enjoy its maximum moisture. For longer storage, place it in an airtight container in the fridge, where it will last for up to 4 days. Just a little tip: if you want to maintain that wonderful texture, consider slightly reheating slices in the microwave for 10-15 seconds before serving!
Can I freeze Lemon Blueberry Sheet Cake?
Unfortunately, I recommend against freezing this particular cake to preserve its wonderfully moist texture. If you must freeze it, wrap individual slices tightly in plastic wrap and store in an airtight container or freezer bag. You can freeze it for up to 3 months, but be aware that thawing may affect the cake’s crumb and moisture balance. To defrost, place it in the refrigerator overnight and enjoy the next day!
What should I do if my cake is dense or dry?
Very importantly, avoid overmixing your batter once you’ve added the flour! This can lead to a denser cake. If you find that your cake is dry, ensure your oven temperature is accurate, or consider using room temperature eggs and softened butter for a fluffier consistency. If you need to adjust the baking time, start checking for doneness a few minutes early.
Are there any dietary considerations for this recipe?
If you’re cooking for someone with allergies, this cake contains eggs, butter, and wheat, so it’s important to adjust according to dietary needs. You can make it gluten-free by using a gluten-free flour blend, and for a dairy-free version, opt for almond milk with a splash of vinegar instead of buttermilk. This way, everyone can enjoy a slice of this delicious Lemon Blueberry Sheet Cake!
