Ingredients You’ll Need

• 3 cups all-purpose flour: This provides the structure and base for your cake. If you’re gluten-free, feel free to substitute with a 1:1 gluten-free flour blend.
• 2 ½ teaspoons baking powder: This gives the cake its rise and fluffiness.
• ½ teaspoon baking soda: Helps to achieve a balanced lift and a moist texture.
• ½ teaspoon kosher salt: Enhances the overall flavors, balancing the sweetness.
• 1 cup (2 sticks) unsalted butter, softened: Richness comes from butter, making for a tender crumb. Make sure it’s softened for easy mixing!
• 1 ¾ cups granulated sugar: Adds sweetness and ensures a moist cake.
• 3 large eggs, room temperature: Aids in proper emulsification and adds structure. Room temperature eggs help to blend smoothly.
• 1 teaspoon vanilla extract: Offers a subtle depth of flavor that complements the lemon.
• 1 cup whole milk, room temperature: Keeps the batter moist and adds richness. If you’re trying to cut calories, you could use a low-fat version.
• 1 tablespoon lemon zest: This brightens up the cake with intense lemon flavor. Always use fresh zest for the best taste.
• ⅓ cup freshly squeezed lemon juice: Adds tartness; about two lemons should suffice for this measurement.
• 1 cup confectioners’ sugar: Used for the glaze, providing sweetness and a smooth texture.
• 1 tablespoon fresh lemon juice: Added to the glaze for an extra zing.
• 1 tablespoon whole milk: This helps achieve the correct consistency for the glaze.

How to Make Lemon Sheet Cake

1. Preheat the Oven: Begin by preheating your oven to 350°F. Line a 9×13-inch baking dish with parchment paper—leave some overhang for easy removal after baking.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this mixture aside to keep the dry ingredients well combined.
3. Cream Butter and Sugar: In a large bowl, use a handheld mixer or a stand mixer fitted with the paddle attachment to beat the softened butter (1 cup) and granulated sugar (1 ¾ cups) on high speed until it’s smooth and creamy—this will take about 3 minutes. Don’t forget to scrape down the sides of the bowl!
4. Add Eggs and Vanilla: Beat in the large eggs (3) and the vanilla extract (1 teaspoon) on high speed until everything is fully combined—around 2 minutes. Make sure to scrape the sides of the bowl again.
5. Combine Dry Ingredients: With the mixer on low speed, gradually add the dry ingredients to the wet mixture in three parts, mixing just until barely combined after each addition. Avoid overmixing, as this can lead to a tough cake.
6. Incorporate Wet Ingredients: Slowly pour in the room temperature whole milk (1 cup) and then mix in the lemon zest (1 tablespoon) along with the freshly squeezed lemon juice (⅓ cup). Blend just until everything is smoothly combined, and no large lumps remain—the batter will be slightly thick.
7. Pour and Spread: Now pour the luscious batter into the prepared baking dish, then spread it into an even layer using a spatula.
8. Bake: Place in the oven and bake for 28 to 35 minutes. The cake is done when a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. Start checking at the 28-minute mark to avoid over-baking—if the edges begin browning too quickly, loosely tent with foil.
9. Cool the Cake: Remove the cake from the oven and let it cool completely in the pan on a wire rack—a process that might take a bit, but it’s worth the wait!
10. Prepare the Glaze: In a medium bowl, whisk together the confectioners’ sugar (1 cup), lemon juice (1 tablespoon), and whole milk (1 tablespoon) until the mixture is smooth and glossy. If you’d like a thinner glaze, slowly add more lemon juice, a teaspoon at a time.
11. Glaze the Cake: Once the cake has completely cooled, pour the delightful glaze over the top, gently spreading it to the edges to create a glossy finish.
12. Set Before Serving: Allow the glaze to set at room temperature for about 20 to 30 minutes before slicing into squares and serving up this delicious lemon sheet cake.

Storing & Reheating

To keep your lemon sheet cake fresh, store it in an airtight container at room temperature for 1-2 days. If you want to keep it longer, you can refrigerate it for about a week. For even longer storage, wrap individual slices in plastic wrap and freeze them for up to 3 months. When ready to enjoy again, let the cake thaw in the fridge overnight or at room temperature for a few hours. The cake may lose a bit of its freshness, but you can revive some moisture by warming it slightly in the microwave for 10-15 seconds.

Chef’s Helpful Tips

• To avoid a dry cake, measure your flour correctly! Scoop and level rather than packing it into the measuring cup.
• Allow your eggs and milk to come to room temperature before mixing; this helps create an even batter and better rise.
• If you want to brighten the lemon flavor even more, try adding a teaspoon of lemon extract into the batter.
• For the best texture, be careful not to overmix once you add the flour; mix just until combined.
• If the edges of your cake brown too quickly, be sure to tent it with foil to prevent burning.

If you’re looking for a show-stopping dessert that’s both easy to make and wonderfully refreshing, lemon sheet cake checks all the boxes. It’s a delightful treat that balances sweetness with a funky twist from lemon, making it perfect for any gathering. But don’t be shy—feel free to experiment! You can infuse your own twist by adding fresh berries or even a dash of lavender to elevate it even further. Grab your whisk and get baking; your taste buds will be grateful!

Recipe FAQs

Can I use bottled lemon juice instead of fresh?

While bottled lemon juice can work in a pinch, fresh lemon juice offers brighter flavor and a natural aroma that just can’t be replicated. You’re better off using fresh lemons for this cake to really capture that tangy essence!

How can I prevent my cake from sticking to the pan?

To prevent sticking, be sure to line your baking dish with parchment paper. This not only makes removal much easier but protects the edges from over-baking as well.

What should I do if my glaze is too thick?

If your glaze ends up thicker than you’d like, simply add a teaspoon of lemon juice or milk at a time until you reach the desired consistency. A thinner glaze can beautifully drape over the cake and create that lovely, glossy finish!

Can I make this cake ahead of time?

Absolutely! This lemon sheet cake can be made up to 1 day in advance. Just keep it covered at room temperature to maintain its texture and flavor. It’s a great treat to bake ahead and have ready for any occasion!
