Official spring may still be around the corner, but springtime has nonetheless started teasing us with its warmer temps and pops of green and flush of flowering. So what say we celebrate with a scrumptious, from-scratch, easy Lemon Sheet Cake?

Lemon Sheet Cake

Y'all know what Texas sheet cake is, right? Traditionally, it's a giant slab of chocolate cake baked in a nice, big sheet pan. The batter is stirred together in a pot on the stove and, once the cake comes out of the oven, a glorious warm frosting is poured right over the cake. It's extremely sweet, moist, and decadent...and it's always a hit.

Personally, however, I've always been a bigger fan of white cake than chocolate cake. So years ago, I started making Vanilla Texas Sheet Cake Cupcakes. Those eventually morphed into a White Texas Sheet Cake. And just last month, I decided to give my tried-and-true recipe a lemon twist.

WHY DID I NEVER THINK TO MAKE LEMON SHEET CAKE BEFORE?!?!

I adore lemon desserts, as evidenced by the fact that not too long ago I shared Lemon Fruit Dip. I've also previously shared one of my favorite lemon cake recipes, Lemon Pound Cake. But wow. This Lemon Sheet Cake is right up there as well!

The first time I ever made it, I took the remnants of this delicious Lemon Sheet Cake to a pool party, and it was met with rave reviews. Everyone loved it, and for good reason.

The cake itself is incredibly moist.

The lemon flavor is prominent but not overpowering.

And the tangy sweet glaze takes it over the top!

Ingredients

The ingredients for this Lemon Sheet Cake are pretty standard to most Texas sheet cakes. This version is simply infused with a big burst of lemon!

Labeled ingredients to make Lemon Sheet Cake, the best lemon cake recipe.

Here are a few notes on some of the most important ingredients in this recipe:

  • Butter. No need to soften it as it's going to be melted in a big ol' pot.
  • Water. To mix with the melted butter. I know it sounds weird, but 'tis the way of a Texas sheet cake.
  • Lemon juice + lemon zest. Two large, juicy lemons yield approximately ½ cup of lemon juice and 2 tablespoons lemon zest. So you'll probably need three large lemons for this recipe...but I'd buy at least four, just in case. And while fresh-squeezed juice is hard to beat, if you decide to save time and opt for a bottle of pure, all-natural lemon juice (as opposed to lemon juice with additives), your cake will still turn out great.
  • Flour, sugar, baking soda, + salt. The usual cake ingredients.
  • Sour cream + eggs. When you stir in the sour cream, it considerably cools down the warm batter. But just to be safe, I usually crack the eggs into a separate bowl and temper them (whisk them and then gradually stir in some of the warm batter). Then I scrape all of the tempered egg mixture into the pot and quickly stir it into the batter. This helps ensure that the eggs won't scramble when they hit the warm batter.
  • Vanilla extract + lemon extract. For an extra boost of flavor.

Lemon Glaze Ingredients

The metaphorical cherry on top of this Lemon Sheet Cake is its topping of tangy lemon glaze. The ingredients are simple!

  • Lemons. You already need lemon juice and lemon zest for the lemon cake recipe, and you'll need a bit more for the lemon glaze.

Tips, Tricks, & Equipment

  • The sheet pan used for this lemon cake recipe measures 18- by 13- inches with a 1-inch rim, commonly referred to a half sheet pan.
  • The key to avoiding an overly-thick batter is to allow the butter mixture to cool down before stirring in the flour. I like to use a big wooden spoon.
  • Pour the lemon glaze over the top of the cake and immediately spread it into an even layer (an offset spatula makes this job easier). The layer of glaze will be thin, but it's sweet and tangy enough that that's all the cake needs!
  • Cover any leftover Lemon Sheet Cake with plastic wrap (I prefer Press 'n Seal). Pull the plastic wrap taut and store the cake in the refrigerator. If you want to increase the odds that the plastic wrap doesn't stick to the glaze, use small pieces of lemon to garnish each slice of cake, as shown in the photos in this post. This will provide a higher "layer" that the plastic wrap can rest on without touching the glaze.
  • If you have leftover lemon juice after zesting and juicing your lemons, you can always freeze it in 1-tablespoon portions in ice cube trays. Once frozen, pop the cubes out of the tray and store in a plastic zip-top bag in the freezer. Thaw as needed for future recipes.

Ingredients

FOR THE CAKE:

FOR THE GLAZE:

  • 3 ½ cups powdered sugar
  • 6 tablespoons fresh lemon juice
  • 1 tablespoon lemon zest

Instructions

  • Adjust the rack to the center position of the oven and preheat the oven to 375°F. Grease a rimmed 18x13x1-inch half sheet pan with softened butter.
  • In a large pot set set over medium heat, melt the butter. Add the water and the lemon juice, increase the heat, and bring to a boil. Remove pot from the heat and allow to cool for at least 5 minutes. Then briskly stir in the flour until smooth, immediately followed by the sugar, sour cream, and lemon zest.
  • Temper the eggs by beating them in a separate bowl and then slowly and gradually whisking in spoonfuls of warm cake batter to bring up the temperature of the eggs. Then stir the tempered eggs into the pot of cake batter until fully incorporated. Mix in the vanilla and lemon extract. Finally, sprinkle the baking soda and salt over the top of the batter (make sure there are no lumps!) and stir them in until all ingredients are well blended.
  • Pour the batter into the prepared sheet pan and smooth the top. Bake for 15 to 18 minutes or until a toothpick inserted into the center of the cake comes out clean. Cool the cake completely before glazing.

FOR THE GLAZE:

  • Once the cake is cool, measure the powdered sugar into a bowl and stir in the lemon juice and zest until completely smooth. Add a bit more lemon juice if the glaze is too thick or a little more powdered sugar if it's too thin.
  • Pour the glaze over the cooled cake and immediately spread into a thin, even layer. If desired, garnish the cake with quarters of lemon slices. Chill (uncovered) for at least 30 minutes to allow the glaze to set before slicing. Cover tightly and refrigerate any leftovers.

Notes

  • The key to avoiding an overly-thick batter is to allow the butter mixture to cool down before stirring in the flour. I like to use a big wooden spoon.
  • The lemon glaze will be thin once it's spread over the cake, but it's so sweet and tangy that not much is required.
  • I prefer using Press 'n Seal to cover leftover Lemon Sheet Cake. Pull the plastic wrap taut and press it along the edges of the pan. If you want to increase the odds that the plastic wrap doesn't stick to the glaze, use small pieces of lemon to garnish each slice of cake, as shown in the photos in this post. This will provide a higher "layer" that the plastic wrap can rest on without touching the glaze.

    Curious as to why using water instead of milk in the batter? I like adding a bit more nutrition into my recipes when I can : )

    1. Hi Lili! I'm not sure of the reason, but Texas sheet cakes are traditionally made with water. 🙂 So I haven't tried substituting milk, but I don't see why it wouldn't work! Please come back and let us know how it turns out if you decide to give it a try.

    Would this cake be good if I ditched the lemon glaze and frosted it with whipped cream and fresh berries?

  3. It’s in the oven! I had to use 6 lemons to get the right amount of juice! You must have some monster lemons!🤪😊

  4. 5 stars
    Perfectly moist cake with lots of lemon flavor, just the right combination of sweet and sour. The glaze, as they say, "is the icing on the cake"!

  5. 5 stars
    This cake is absolutely delicious! I've made it twice now and every person that tried it was crazy about it! A definite winner and it will be a regular at our parties. Thanks for this gem of a recipe!

    1. Hi Nancy! I'm sorry, but I have not made this particular recipe as cupcakes. That being said, I converted my favorite vanilla sheet cake recipe to cupcakes, so you could probably use that recipe as a guide for converting this one (as far as baking time). The vanilla sheet cake cupcakes are a smaller scale recipe, however, so this lemon sheet cake batter will give you a few more cupcakes. Alternatively, you could just opt to make my favorite lemon cupcake recipe instead. Hope that helps! 🙂

  6. I only have a 12x17 pan. Don't know how much it rises and would overflow if I put all the batter in?

    1. Hi Dawn! This recipe was developed for a true 18x13x1" half sheet pan, so it would certainly overflow your pan. You could try baking some of the excess batter in a few muffin cups, but unfortunately, I can't advise on exactly how much batter to put in your specific pan to guarantee no overflowing. I wouldn't want you to end up with a mess in your oven if you accidentally put too much batter in your pan!

    I made this for a Pot Luck tonight and MANY friends asked for the recipe. It's a keeper! Thank you for sharing this...

    Ohhhhhh man was this cake delicious! I read a bunch of comments beforehand (as I do for any recipe to see if there's any tips, etc) and was thrown off by so many people saying the batter was "so thick" or like "cookie dough consistency." I'm a firm believer that if you follow the recipe to a T, it will come out. I did just that and it was absolutely perfect. I assume other people had not let the butter/water/lemon juice cool for at least 5 minutes before adding in the dry ingredients, but, if your read the recipe, it tells you to wait five minutes 🙃. It's rare that I take the time to bring out my measuring tape while baking to get the cuts of the cake perfect, but you bet your a$$ I did for this. I wanted each and every square cut to be beautiful! My boyfriend's grandparents send us a box of lemons from their Meyer lemon tree every year and this time, I made this cake with them. For the lemon garnish on top, I decided to cut the lemon wheels into sixths and sit between paper towels to absorb some of the moisture out of them before setting them on top of the slices. I brought the cake to a party and everyone loved it so much and I've had multiple people ask for the recipe already!

    WOW! I baked this for the first time today and it truly is a 5-star recipe! It came out better than expected and was super easy to assemble. I didn't change a thing. This cake will be a go-to from now on for gatherings and pot-lucks.
    Thank you so much for creating it❤️

    1. More baking time = further browning, but if the cake is already done, you don't want to overbake it and dry it out. I think it's fine if it doesn't brown as long as it tests done and tastes good. 🙂

    Made this for my lemon loving mama for Mother's Day 2021. She, my dad, my brother and I LOVED it! It's so moist and delicious...so much so that mom and dad had to help themselves to two pieces. Also, it's truly awesome that this doesn't take long to bake in the oven. Truly 5 stars and a recipe that we'll keep in our family for a long long time!! Thank you for sharing this recipe ♥

    I have now made this 3 times...and it's a keeper! So easy, so tangy and my family loves it. I don't have a half sheet pan so I use a 9X13 -- but I'm going to get a half sheet JUST for this recipe! Thanks for sharing!!!

  12. 5 stars
    I don't comment much, but I just had to on this recipe. I'm a sucker for anything lemon and this is one of the best cakes I have baked and tasted. It's WAY better than anything out of a box. I believe this will be the dessert that I take to funeral meals and potlucks. Thanks do much for sharing!

  13. Hi there made this cake and I think that it came out a little gummy on the bottom when I cut in in to squares maybe did not cook long enough but was in the oven 18 minutes and checked it toothpick come back clean?

    1. Hi Barbara! This is a very moist cake and definitely does not get dry on the bottom. But by what you're describing, yes, it may have needed another minute or two in the oven.
