Ingredients for Lemon Blueberry Sheet Cake

I like to keep my ingredients simple and pantry-friendly. Here’s what you’ll need:

For the Cake

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 tbsp flour

For the Lemon Glaze

2 1/2 cups powdered sugar
1/3 cup lemon juice

Tip: If you’re craving something richer, swap the glaze for cream cheese frosting and turn this into a lemon blueberry sheet cake with cream cheese frosting. My kids are team glaze, but my husband always votes cream cheese.

How to Make Lemon Blueberry Sheet Cake

This cake comes together in under an hour (plus cooling time). Here’s how I do it:

Prep the Pan
Preheat the oven to 350°F. Grease a 9×13 baking dish and line with parchment paper, leaving some overhang for easy removal. This step makes cleanup a breeze.
Mix Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Meanwhile, set your stand mixer up for the wet ingredients.
Cream Butter & Sugar
In a stand mixer (or with a hand mixer), beat butter and sugar until light and fluffy. This step is key because it creates the airy texture of the cake.
Add Wet Ingredients
Mix in eggs one at a time, then add vanilla, buttermilk, lemon juice, and lemon zest. At this point, the batter should smell amazing.
Combine
Slowly add the dry ingredients to the wet mixture. Mix until just combined—don’t overmix or the cake will be dense.
Add Blueberries
Toss blueberries with a little flour (to prevent sinking). After that, gently fold them into the batter.
Bake
Spread the batter into the prepared pan. Then bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean or with moist crumbs.
Cool & Glaze
Let the cake cool completely before drizzling with glaze. Finally, garnish with extra blueberries or lemon slices if you like.

Tips for the Best Lemon Blueberry Sheet Cake

Over the years, I’ve learned a few tricks that make this cake extra special:

Room temperature butter and eggs make the batter smoother.
Don’t skip the flour coating on the blueberries—it helps them stay suspended.
Fresh lemons only! Bottled lemon juice won’t give the same zing.
Check early – Ovens vary, so peek at 38 minutes to avoid overbaking.
Glaze on a cooled cake – Otherwise, the glaze melts into the cake instead of setting beautifully.

In addition, if you want to add extra flair, try garnishing with edible flowers or a dusting of powdered sugar before serving.

Can I Use Cake Mix Instead?

Yes! If you’re short on time, you can make a lemon blueberry sheet cake using cake mix. Just grab a yellow or lemon cake mix, add fresh lemon juice and zest for extra flavor, and fold in the blueberries. As a result, you get the same delicious cake with less effort.

FAQs About Lemon Blueberry Sheet Cake

Can I use frozen blueberries instead of fresh?
Yes! However, make sure to add them straight from the freezer so they don’t turn the batter purple.

How do I store Lemon Blueberry Sheet Cake?
Cover tightly and keep at room temperature for 2 days, or refrigerate for up to 5 days. In either case, it stays fresh and moist.

Can I make this cake ahead of time?
Definitely. You can bake the cake the night before, then glaze right before serving.

What frosting goes best with this cake?
Cream cheese frosting is my personal favorite when I want something richer than glaze. On the other hand, the lemon glaze keeps it light and refreshing.

How can I make this cake lighter or healthier?
Try using Greek yogurt in place of half the butter, or reduce the sugar slightly. As a result, you’ll have a lighter cake without losing much flavor.

Can I bake this in a different pan?
Yes! A bundt pan or cupcake tins both work—just adjust the bake time accordingly.

Why did my blueberries sink to the bottom?
They weren’t coated in flour, or your batter was too thin. Therefore, always toss them in flour before folding in.
