Lemon Sheet Cake

Sheet cakes are some of my favorite treats to bake and eat. They’re incredibly simple, but they’re always crowd-pleasers.

And this recipe is no exception!

Whip it up for a summer party, or in the winter when you need something sunny.

There’s no wrong time for this stunning lemon sheet cake.

Ingredients

Don’t let the long ingredient list fool you! Other than fresh lemons, I bet you have everything you need in your pantry right now.

Here’s a quick breakdown:

• All-Purpose Flour: No fancy flour is needed here! All-purpose flour will deliver a perfect rise in the oven.

• Baking Powder and Baking Soda: This combo gives you just the right amount of rise.

• Salt: To draw out the natural flavors and balance the lemon and sugar.

• Granulated Sugar: A little sweetness to combat the tartness of citrus.

• Unsalted Butter: Softened butter brings richness and moisture to the sponge.

• Eggs: Another way to bring richness and moisture. But they also help the cake rise.

• Lemon Zest and Juice: For maximum citrusy goodness! You’ll need the juice in the cake and the glaze.

• Vanilla Extract: You could leave this out, but it adds a rounded depth of flavor that I adore.

• Sour Cream or Buttermilk: The lactic acid in sour cream or buttermilk breaks down the protein in the flour, creating a more tender, moist cake.

• Powdered Sugar: A simple blend of lemon juice and powdered sugar is all you need over this cake.

Recipe Tips and Variations

This lemon sheet cake is super simple, but there are a few things to keep in mind.

So, take your time, and be sure to check out these quick tips and variations!

• Use parchment paper and butter. This cake loves to stick to the pan. So, use a combo of butter (or cooking spray) with parchment paper to ensure it comes out without breaking.

• Beat that butter! Make sure it’s smooth and lump-free before adding the eggs. Generally, it takes about 3 minutes for the butter and sugar to turn a pale yellow and become light and fluffy.

• Alternate adding the flour and sour cream. This step seems finicky, but it makes a world of difference. Start with the flour, add some sour cream, and repeat. Be sure to end with the flour too.

• Cool the cake completely. If you pour the glaze over a warm cake, it will absorb all the sugar and vanish. So, make sure the cake is cold so it can set properly.

• Citrusy variations. Feel free to try this with orange, lime, or grapefruit!

How to Store

The best thing about sheet cake is there are always leftovers! Be sure to follow these storage tips so your cake stays as fresh as possible.

Note: you can freeze leftovers with the glaze, but it might thaw and turn watery. So it’s best to scrape it off and make the glaze fresh.

Lemon Sheet Cake With Lemon Glaze

This easy lemon sheet cake is bright, airy, and oh-so-lemony. If you are a lemon-head like me, you’ll love it.

Ingredients

• For the Cake

• 2 1/2 cups all-purpose flour

• 1 teaspoon baking powder

• 1/2 teaspoon baking soda

• 1/2 teaspoon salt

• 2 cups granulated sugar

• 1 cup unsalted butter, softened

• 4 large eggs

• 2 tablespoons lemon zest (about 2 large lemons)

• 1/2 cup freshly squeezed lemon juice (2-3 large lemons)

• 1 teaspoon vanilla extract

• 1 cup sour cream or buttermilk

• For the Lemon Glaze

• 3-4 cups powdered sugar, sifted

• 1/4 cup freshly squeezed lemon juice (1-2 large lemons)

• 1 tablespoon lemon zest for garnish, optional

Instructions

• Preheat the oven to 350 degrees Fahrenheit (175°C). Grease a 9×13-inch baking pan with butter or cooking spray, line it with parchment paper, and set aside.
• In a large bowl, whisk the flour, baking powder, baking soda, and salt until well blended.
• In a separate large bowl, beat the sugar and butter with an electric mixer until light and fluffy – about 5 minutes. Add the eggs one at a time, beating well after each addition until smooth. Finally, add the lemon zest, lemon juice, and vanilla, and stir to combine.
• Alternate adding the dry ingredients and sour cream, starting and ending with the flour. Stir by hand with a spatula until just combined and no streaks of flour are visible.
• Pour the batter into the prepared pan, smooth the top with a spatula, and bake for 30-35 minutes or until a toothpick inserted in the middle comes out clean. Remove from the oven and let cool on a wire rack.
• While the cake is cooling, add 3 cups of powdered sugar to a large bowl. Slowly whisk in the lemon juice until smooth and lump-free. Add more powdered sugar, as needed.
• Pour the glaze over the cooled cake and spread evenly over the surface. Garnish with lemon zest, if desired, and chill for 20-30 minutes or until the glaze is set. Then slice, serve, and enjoy!

Notes

• Use an 18×13-inch half-sheet tray for a thinner cake, or two 8×8 round pans. They will only need 20-25 minutes in the oven.
• After adding the lemon juice, the batter may appear curdled. That’s okay. It will smooth out when mixed with the flour.
