Ingredients You’ll Need

3 cups (354 g) all-purpose flour: This is the base for a soft and fluffy cake. You can substitute with a gluten-free blend, but make sure it’s designed for baking.
2 ½ teaspoons baking powder: This helps the cake rise perfectly. Don’t skip this to ensure a light texture.
½ teaspoon baking soda: Balances out acidity in the lemon juice and boosts the rise. It’s essential for achieving the perfect crumb.
½ teaspoon kosher salt: Enhances the flavors in your cake—a must-have!
1 cup (2 sticks / 227 g) unsalted butter, softened: Brings richness and moisture to the cake. For a dairy-free option, you can use a vegan butter substitute.
1 ¾ cups (350 g) granulated sugar: Sweetens the cake beautifully, helping to balance the tartness of the lemon.
3 large eggs, room temperature: Eggs provide structure. Ensure they are at room temperature for optimal mixing.
1 teaspoon vanilla extract: Adds depth to the flavor profile. You can use pure vanilla for a more natural taste.
1 cup (244 g) whole milk, room temperature: The milk keeps the cake moist. Feel free to substitute with almond milk for a dairy-free option.
1 tablespoon lemon zest, about 2 lemons: The zest gives an intense lemon flavor. Make sure to zest before juicing!
⅓ cup freshly squeezed lemon juice, about 2 lemons: Provides that signature brightness everyone loves.
1 cup (125 g) confectioners’ sugar: For the glaze, it adds sweetness without making it too heavy.
1 tablespoon fresh lemon juice: Enhances the lemony brightness in the frosting.
1 tablespoon whole milk: Ensures the glaze reaches the right consistency.

How to Make Lemon Sheet Cake

Preheat the oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13 inch sheet cake pan with butter or non-stick spray.
Combine dry ingredients: In a medium bowl, whisk together 3 cups all-purpose flour, 2 ½ teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon kosher salt. Set aside.
Cream butter and sugar: In a large mixing bowl, cream together 1 cup softened unsalted butter and 1 ¾ cups granulated sugar until light and fluffy, about 3-4 minutes.
Add eggs and vanilla: Beat in 3 large eggs, one at a time, then add 1 teaspoon vanilla extract. Mix until well combined.
Incorporate milk and lemon: Gradually alternate adding the flour mixture and 1 cup room temperature whole milk into the butter mixture. Mix until just combined. Gently fold in 1 tablespoon lemon zest and ⅓ cup freshly squeezed lemon juice until incorporated.
Bake the cake: Pour the batter into the prepared pan and smooth the top. Bake in the preheated oven for 28 minutes, or until the edges are golden, and a toothpick inserted in the center comes out clean.
Cool the cake: Once done baking, allow the cake to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely before icing.
Make the glaze: In a small bowl, whisk together 1 cup confectioners’ sugar, 1 tablespoon fresh lemon juice, and 1 tablespoon whole milk. Adjust the consistency with more milk or sugar, if needed.
Glaze the cake: Once cooled, pour the glaze over the top of the cake, spreading it evenly for maximum coverage.

Storing & Reheating

Store any leftover Lemon Sheet Cake at room temperature in an airtight container for up to 3 days. If you need to keep it longer, transfer to the refrigerator where it can last about a week. For freezing, wrap slices in plastic wrap and then place them in a resealable freezer bag. This will last for up to 3 months. When you’re ready to enjoy again, let it thaw at room temperature or warm briefly in the microwave until just heated through. Be aware that the glaze might lose some of its original texture when frozen, but a quick refresh with a drizzle of fresh lemon juice can bring it back to life.

Chef’s Helpful Tips

Make sure your butter is softened properly; it should be pliable but not melted.
Resist overmixing the batter once you add the flour; mixing just until combined helps maintain that cake’s tenderness.
Use fresh lemons for zest and juice; the flavor is far superior to bottled lemon juice.
If your cake sinks while baking, it could mean too much liquid was added or not enough baking powder was used. Always measure accurately!
Adding a bit of extra lemon zest to the icing can enhance that zesty flavor.
This cake can be made a day in advance and still tastes delicious, making it perfect for events.

A slice of this Lemon Sheet Cake is not just a dessert; it’s a moment of joy. It combines flavors that dance on your palate, and the cozy feeling it brings is unmistakable. Whether it’s the center of attention at a gathering or a happy treat just for you, don’t hesitate to give this recipe a try. It’s an easy and hearty way to bring a burst of sunshine into your life.

Recipe FAQs

Can I use frozen lemons for this cake?

Frozen lemons can be used, but fresh lemons will provide the best flavor and zest. If you use previously frozen lemons, make sure they are completely thawed before juicing or zesting.

Can this lemon sheet cake be made ahead of time?

Absolutely! You can bake the cake a day in advance, and it will keep its flavor and texture. Just store it covered at room temperature or in the refrigerator until ready to serve.

How can I make this dish gluten-free?

To make this cake gluten-free, substitute the all-purpose flour with a 1:1 gluten-free baking blend. Ensure that your other ingredients, like baking powder, are also gluten-free.

What should I do if my cake is dry?

If you find your cake turns out dry, it could be due to overbaking or incorrect measuring of flour. Always use the spoon-and-level method for measuring flour. If you do end up with a dry cake, serve with whipped cream or ice cream to add moisture and flavor.
