• 1/2 cup milk: Brings moisture and helps create a tender crumb.
• 1/2 cup sour cream: Adds tang and extra moistness to the cake.
• 2 tablespoons lemon zest (divided): Infuses bright citrus flavor in both batter and glaze.
• 3 tablespoons fresh lemon juice (divided): Delivers fresh, tangy zip throughout.

How To Make Lemon Blueberry Sheet Cake with Lemon Glaze

This recipe comes together in a few simple stages—mixing dry ingredients, creaming butter and sugar, folding everything gently, and finishing with a bright glaze. It’s beginner-friendly, and each step sets you up for a cake that’s tender, flavorful, and dotted with plump blueberries.

1. Preheat the oven to 350°F and grease a 9×13-inch baking pan to prevent sticking.

2. In a medium bowl, whisk together the flour, baking powder, and salt; set this dry mix aside.

3. In a large bowl, cream the softened butter and sugar until the mixture is light and fluffy, about 2–3 minutes.

4. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next for even texture.

5. Stir in the milk, sour cream, 1 tablespoon lemon zest, 2 tablespoons lemon juice, and vanilla extract until just combined.

6. Gradually fold the dry ingredients into the wet mixture, stopping as soon as you see no streaks of flour.

7. Gently fold in the blueberries, then pour the batter into the prepared pan and smooth the top with a spatula.

8. Bake for 25–30 minutes until the cake is golden and a toothpick inserted into the center comes out clean.

9. While the cake bakes, whisk together the powdered sugar, remaining 1 tablespoon lemon juice, and remaining 1 tablespoon lemon zest until smooth to make the glaze.

10. Remove the cake from the oven and let it cool in the pan for 10 minutes before drizzling the lemon glaze over the top.

11. Allow the glaze to set for a few minutes before slicing and serving.

Tips For Perfect Lemon Blueberry Sheet Cake with Lemon Glaze

A few insider notes can take your sheet cake from “good” to “spectacular.” Keep these friendly tips in mind as you bake to ensure every bite is bursting with bright blueberry and zesty lemon goodness.

• Use fresh or frozen blueberries tossed in a little flour to help prevent sinking.
• Let the cake cool slightly before adding the glaze for the best texture.
• Store any leftovers covered in the refrigerator for up to 3 days.
• Room temperature ingredients help the batter combine more smoothly.

How To Store It

Preserving the cake’s moist crumb and shiny glaze is simple with the right storage methods. Whether you’ve got a full cake or a few leftover squares, these tips will keep every bite as delightful as day one.

• Refrigerate in pan: Cover the cooled cake tightly with plastic wrap and store in the fridge for up to 3 days.
• Airtight container: Slice the cake and arrange pieces in an airtight container, separating layers with parchment paper.
• Freeze slices: Wrap individual slices in plastic and freeze for up to 1 month—thaw overnight in the fridge.
• Room temperature: If consuming within 24 hours, keep the cake loosely covered on the counter away from direct sunlight.

Frequently Asked Questions

Here are answers to some common questions about this bright, fruity sheet cake:

• How long does it take to prepare and bake the Lemon Blueberry Sheet Cake with Lemon Glaze?

A: From start to finish, plan for about 15 minutes to prepare the batter and preheat the oven, 25–30 minutes to bake, plus 10 minutes for initial cooling and another 10–15 minutes for the glaze to set, for a total of roughly 60 minutes.

• Can I use frozen blueberries instead of fresh ones?

A: Yes, you can substitute frozen blueberries. To prevent them from sinking in the batter, gently toss the frozen berries with about a tablespoon of flour before folding them into the mixture. There’s no need to thaw them first.

• How can I tell when the cake is fully baked?

A: The cake is done when its top is light golden and a toothpick inserted into the center comes out clean or with just a few moist crumbs attached. Avoid overbaking to keep the crumb tender.

• What’s the best way to add the lemon glaze so it sets properly?

A: After removing the cake from the oven, let it cool in the pan for about 10 minutes until it’s warm but not hot. Drizzle the glaze evenly over the surface and allow it to sit for 10–15 minutes. This resting time helps the glaze firm up and creates a shiny finish.

• What can I use as a substitute for sour cream if I don’t have any on hand?

A: You can swap in an equal amount of plain Greek yogurt for similar tang and moisture. Alternatively, use a homemade buttermilk by stirring one tablespoon of vinegar or lemon juice into ½ cup of milk and letting it sit for 5 minutes before adding it to the batter.

• How should I store any leftover cake, and how long will it keep?

A: Once the glaze has set, cover the pan tightly with plastic wrap or transfer slices to an airtight container. Store in the refrigerator for up to 3 days. Bring slices to room temperature or warm gently in the microwave before serving for best texture.

• Why does the recipe call for room-temperature ingredients, and how does that affect the cake’s texture?

A: Using room-temperature butter, eggs, and dairy ensures they blend smoothly into a homogeneous batter. This helps trap air during creaming, yielding a light, fluffy crumb and even rise in the baked cake.
