Ingredients You’ll Need

3 cups (354 g) all-purpose flour: This forms the base of your cake, providing the perfect structure. You can substitute with gluten-free flour if needed.
2 ½ teaspoons baking powder: A key leavening agent that helps the cake rise beautifully.
½ teaspoon baking soda: Complements the baking powder for a light cake texture.
½ teaspoon kosher salt: Enhances all the flavors in the cake.
1 cup (2 sticks / 227 g) unsalted butter (softened): Adds richness and moisture. Be sure to bring it to room temperature for easy creaming.
1 ¾ cups (350 g) granulated sugar: Sweetens the cake and helps create a tender crumb.
3 large eggs (room temperature): Gives structure and moisture. Eggs at room temperature mix more easily.
1 teaspoon vanilla extract: A classic flavor enhancer that complements the lemon.
1 cup (244 g) whole milk (room temperature): Adds moisture to the batter. Again, room temperature is key.
1 tablespoon lemon zest (about 2 lemons): Infuses that bright lemon flavor without too much tang.
⅓ cup freshly squeezed lemon juice (about 2 lemons): This provides the zesty kick that makes the cake so special!
1 cup (125 g) confectioners’ sugar: For the joyful glaze that gives a sweet finish.
1 tablespoon fresh lemon juice: Adds an extra burst of flavor to the glaze.
1 tablespoon whole milk: Helps to achieve the perfect spreadable consistency for the icing.

How to Make Lemon Sheet Cake

Preheat your Oven: Heat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan, or line it with parchment paper for easy removal later.
Mix Dry Ingredients: In a mixing bowl, whisk together the 3 cups all-purpose flour, 2 ½ teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon kosher salt until well combined.
Cream Butter and Sugar: In another large bowl, beat 1 cup (2 sticks) of softened unsalted butter with 1 ¾ cups granulated sugar using an electric mixer on medium speed until the mixture is light and fluffy—a good 3 minutes!
Add Eggs and Vanilla: Add 3 large eggs, one at a time, mixing well after each addition. Toss in 1 teaspoon of vanilla extract and mix until everything is well-blended.
Combine with Dry Ingredients: Slowly add the flour mixture to the wet ingredients, alternating with 1 cup (244 g) of room-temperature whole milk. Start and end with the flour mixture, mixing until just combined—don’t overmix!
Incorporate Citrus: Gently fold in 1 tablespoon of lemon zest and ⅓ cup of freshly squeezed lemon juice. The batter should be thick and vibrant!
Pour and Bake: Pour the batter into your prepared baking pan, smoothing out the top. Bake in the preheated oven for 28-30 minutes, or until a toothpick inserted into the center comes out clean. Let it cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
Prepare the Icing: In a small bowl, whisk together 1 cup confectioners’ sugar, 1 tablespoon of fresh lemon juice, and 1 tablespoon of whole milk until smooth. If the glaze is too thick, add a tiny bit more milk until you reach your desired consistency.
Finish Your Cake: Once the cake has cooled completely, drizzle the glaze generously over the top, allowing some to drip down the sides. Let it set before slicing into squares and serving.

Storing & Reheating

To keep your Lemon Sheet Cake fresh, store it at room temperature for 2-3 days in an airtight container. If you prefer a longer storage option, refrigerate it for up to a week. You can also freeze your Lemon Sheet Cake—just ensure it’s wrapped tightly in plastic wrap and foiled for up to 3 months. For serving, you can enjoy it straight from the fridge or pop it in the microwave for about 10-15 seconds for a warm slice, though be aware that some texture may change after freezing.

Chef’s Helpful Tips

Room Temperature Ingredients: Make sure your butter, eggs, and milk are at room temperature for the best emulsion and rise.
Don’t Overmix the Batter: This ensures a tender crumb; mix just until you see no dry flour.
Use Fresh Lemons: Fresh lemon juice and zest are essential for achieving that bright, vivid flavor—bottled versions just won’t cut it.
Let it Cool Completely: Don’t rush the cooling process; glazing a warm cake will cause the icing to melt away and disappear!
Experiment with Flavors: For a flavorful twist, consider adding poppy seeds or even a hint of lavender for a floral note.

This Lemon Sheet Cake is wonderfully light and refreshing, perfect for gatherings or a delightful treat just for you. With straightforward steps and a few simple ingredients, you can create a show-stopping dessert that impresses every time. I encourage you to try it—maybe even tweak the flavors to make it your own—and enjoy every crumb. Baking is a virtue, and there is nothing quite like sharing your creations with loved ones!

Recipe FAQs

Can I make this cake gluten-free?

Absolutely! You can swap out the all-purpose flour for a gluten-free flour blend. Just make sure your blend includes a binding agent, like xanthan gum, to maintain the cake’s structure.

How long does the cake stay fresh?

When stored properly in an airtight container, your Lemon Sheet Cake will stay delicious for about 2-3 days at room temperature. If you refrigerate it, it can last up to a week.

Can I add frosting instead of a glaze?

Of course! If you prefer a more traditional frosting, you can whip up a buttercream icing using powdered sugar, butter, and a splash of lemon juice or zest to give it that lemony flavor.

What’s the best way to slice the cake?

For neat slices, use a sharp knife that has been warmed under hot water and dried; this technique helps make clean cuts without tearing the soft cake.
