Ingredients Needed

For the lemon cake:

  • Sugar– This is key to not only sweetening your cake but also to tenderize it as well. I used granulated sugar.
  • Butter– I used salted butter, but unsalted butter will also work. Just add a pinch of salt.
  • EggsRoom-temperature eggs are a must so they blend in easily to your batter otherwise they will seize up the butter.
  • Milk–  I used whole milk for richness, but any milk will work.
  • Lemon Juice– You can use fresh lemon juice from a lemon or store-bought juice
  • Lemon Zest– You will need 1 whole lemon for the lemon zest.
  • Flour–  I used regular all purpose flour for this cake, which I think created the perfect texture for this cake. Make sure you are measuring your flour correctly so you don’t end up with a dense cake. I recommend weighing for best accuracy, or you can read more here about How To Measure Flour
  • Baking Powder– This is what will leaven your cake, or help it to rise. Be sure your baking powder is fresh, and hasn’t expired. To check it, put a teaspoon of it in a small bowl of hot water If it bubbles, you’re all set! If not, throw it out and get a new container.
  • Baking Soda– Baking Soda works with Lemon Juice to help the cake rise. Baking soda and baking powder are different, so do not mix them up!

For the buttercream:

  • Butter-  I used unsalted butter in my frosting so the frosting wasn’t too salty. Different brands will use varying amounts of salt in their salted butter, so it’s best to use unsalted butter so you can control the amount of salt.  You can read more here about Unsalted Butter Vs. Salted Butter In Baking.   Make sure you’re using softened butter before you begin. 
  • Confectioners Sugar- You need confectioners sugar (or powdered sugar) for the buttercream frosting. I don’t sift my sugar anymore but just make sure to whip it long enough. If you don’t have any powdered sugar, make some at home in your food processor with granulated sugar!
  • Heavy Cream– To thin out your frosting and add a bit of richness and creaminess. But milk or half and half also works!
  • Lemon Juice– Fresh lemon juice is best, but store-bought works fine too.
  • Vanilla Extract–  Again this helps to make for the perfect flavor. Pure vanilla is best for flavor but vanilla extract works too.

How to Make Lemon Sheet Cake

Preheat Oven and Prepare Baking Dish

Preheat the oven to 350°F (180oC). Grease a 9×13 inch cake pan with butter or nonstick cooking spray (or nonstick baking spray) and set aside. Or you can also line with parchment paper for easy removal.

Combine Butter and Sugar

Use an electric hand mixer to cream the butter and sugar together on medium speed until smooth and creamy, about 2 minutes. I like to use my stand mixer fitted with a paddle attachment but a hand mixer also work.

Add Eggs, Milk, and Lemon Juice.

Let the Cake Cool.

Let the cake cool completely in the prepared baking pan on a wire rack before frosting. 

For the Lemon Frosting:

Combine Butter and Lemon Zest.

To make the frosting, in a large bowl, with an electric mixer, beat together the butter and lemon zest together on medium speed for about 1-2 minutes.

Add Powdered Sugar.

Then add in the powdered sugar, with the mixer off 1/2 cup at a time. And the mix on low until combined.

Mix Thoroughly.

Then increase the speed for 2-3 minutes until light and fluffy.

Add Heavy Cream, Lemon Juice, and Vanilla.

Add the heavy cream, lemon juice, and vanilla. Mix on low until combined. It may curdle at this point but will smooth out during mixing.

Continue Mixing and Spread on Sheet Cake.

Mix for 8 minutes until light and fluffy. Top the lemon cake with the lemon frosting, slice, serve, and enjoy!

Recipe Tips

  • Be sure to measure your flour correctly. Over-measured flour can result in a tough dense lemon cake as apposed to the light and fluffy one that we want. So be sure to scoop and level the flour into your cup. For a full nerdy tutorial on measuring flour you can read this post.
  • Make sure your ingredients are at room temperature. Room-temperature ingredients will just play nicely together. You want everything incorporated into one smooth batter.
  • Check Those Leavening Agents. This cake relies on your baking powder for it to rise. So make sure your baking powder is fresh! If you are not sure, then test a teaspoon of it out into a bowl of warm water. It should bubble. If it doesn’t then it’s time to throw it out and buy some new stuff.
  • Do Not Overmix The Flour Mixture. Once you have added the dry ingredients to the bowl, you want to make sure to not mix the batter too much. The more you mix the ingredients at this point, the tougher the cake will be come in the end. So once the last of the flour mixture has been mixed in, stop mixing.
  • Cool cake completely. Make sure your cake is completely cooled before you frost, or your frosting will melt if you spread onto a warm cake.

Recipe Variations

  •  Add Lemon Slices to this Lemon Sheet Cake. You can add a sliced lemon or a bit of lemon zest as a fun garnish to this delicious cake.
  • Add More Lemon. For some extra flavor, you can add the lemon zest of two lemons instead of one to this sheet cake.
  • Make It Sweeter. This sheet cake is soft and moist with plenty of lemon flavor. If you want to add some sweetness to balance the zest of the lemon, you can use vanilla buttercream frosting instead of lemon frosting.
  • Serve with fresh berries. For a pop of color and sweetness, serve with some berries like raspberries, blueberries, or strawberries!
  • Add Lemon Curd – Spread on some lemon curd before frosting the cake for even more lemon flavor.
  • Serve with whipped cream – For a bit lighter bite, instead of the frosting, you could serve with a dollop of homemade whipped cream.
