Essential Ingredients for Lemon Blueberry Sheet Cake
Fresh Blueberries: These little gems add juicy pops of sweetness and color to your Lemon Blueberry Sheet Cake. I always go for fresh ones in season for the best flavor, but frozen work too—just toss them in flour to prevent sinking. They pair so well with the lemon, creating that signature burst everyone loves.
Lemon Zest and Juice: The zest infuses bright citrus aroma, while the juice adds tangy moisture throughout the batter. In my experience, using both from the same lemons maximizes flavor without overpowering the cake. It’s what makes this Lemon Blueberry Sheet Cake stand out from ordinary fruit cakes.
All-Purpose Flour: This forms the tender base, giving your Lemon Blueberry Sheet Cake its light, fluffy crumb. Sifting it helps avoid lumps and ensures even rising. Combined with baking powder, it keeps everything airy and delightful.
How to Make Lemon Blueberry Sheet Cake
Prepare the Batter
Start by preheating your oven to 350°F and greasing a 9×13-inch sheet pan— this Lemon Blueberry Sheet Cake needs that space to spread evenly. In a large bowl, cream together softened butter and sugar until light and fluffy; it should take about 2 minutes with an electric mixer. Beat in eggs one at a time, then mix in vanilla, lemon zest, and juice for that fresh kick.
Here’s the thing: alternating dry ingredients like flour, baking powder, and salt with milk keeps the batter smooth and prevents overmixing, which could toughen the cake. Fold in the blueberries gently at the end so they stay whole and distribute beautifully. Pour everything into the pan and smooth the top—it’s ready for the oven in no time.
Bake to Perfection
Slide the pan into the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean with a few moist blueberry bits. The edges will turn golden, and the house will fill with that irresistible lemon scent—trust me, it’s heavenly. Don’t overbake; you want your Lemon Blueberry Sheet Cake moist, not dry.
While it bakes, the blueberries will soften and release their juices, creating little pockets of flavor. Let it cool in the pan on a wire rack for about 15 minutes before frosting, if using. This step ensures the cake holds its shape when sliced.
Add Finishing Touches
Once cooled, whip up a simple lemon glaze by mixing powdered sugar with fresh lemon juice until pourable. Drizzle it over the top of your Lemon Blueberry Sheet Cake for extra zing, or dust with powdered sugar for a lighter look. Slice into squares and serve—it’s that easy.
The glaze sets quickly but keeps the cake tender. In my experience, letting it sit for an hour after glazing allows flavors to meld even more. Now you have a stunning dessert ready to enjoy!

- 04 1 1/4 teaspoon salt
- 05 1 cup butter ((2 sticks), softened)
- 06 1 1/2 cup granulated sugar

- 12 2 1/2 cup powdered sugar
- 13 1/3 cup lemon juice
Instructions
Preheat the oven to 350 degrees F. Grease a 9×13 baking dish, and line with parchment paper so there’s an overhang over the two long sides of the pan. This will make removing the cake much easier!
In a medium mixing bowl, whisk together the dry ingredients, flour through salt. Set aside. In a stand mixer fitted with the paddle attachment (or hand mixer), cream together the sugar and butter until light and fluffy. Add the eggs and vanilla, and buttermilk, and mix on low until incorporated. Add the dry ingredients, and mix until no streaks of flour remain. Mix in the lemon juice and zest. Gently stir in the blueberries with a spatula.
Pour the cake batter into the prepared 9×13 baking dish, and bake for about 40-45 minutes, or until a toothpick comes out with moist crumbs. Allow to cool completely. You can lift the cake out of the pan before drizzling, or leave it in the dish to serve. Either way works!
For the glaze: combine the powdered sugar and lemon juice, and pour over the cooled cake. Let the glaze harden, and then garnish with fresh fruit and serve!
