Lemon Texas sheet cake is perfect for feeding a tasty dessert to a crowd. It is so easy to make and has just the right amount of lemon flavor. Take it to your next BBQ, family reunion or potluck!

This lovely sheet cake is bursting with lemony citrus flavor. It is perfect for feeding a crowd.
The batter is made in a saucepan just like the chocolate Texas sheet cake we all know and love. But this version is brighter and tastes so fresh. Make one and see for yourself!
Did you know that Texas Sheet Cakes can come in other flavors than chocolate? It’s true! I know that chocolate is the traditional version everyone knows and loves, but the possibilities don’t have to end there.
In fact there are a ton of flavors you could make. Now I do have a variety of jelly roll sheet cakes on the blog.
There’s the Elvis version. It features a banana sheet cake with peanut butter icing and optional bacon.
There’s the banana with salted caramel cream cheese frosting and both of those are amazing. But MiMi says they are NOT Texas sheet cakes.

You see she has rules for what qualifies and what doesn’t. In her world, obviously it has to be baked in the half sheet jelly roll pan to feed a Texas sized crowd.
You might think that’s the qualifier, but the rules according to MiMi don’t end there. No sirree!
In addition to the size, the batter also has to be made with the boiling water and butter. That is her favorite part of sheet cake recipes, not having to think ahead and letting things soften!


So with that in mind, this lemon sheet cake is a true Texas sheet cake.
That is if MiMi is the one that makes the rules.
And she normally is!

That is why she used that method to make her chocolate chip cookie dough sheet cake, one of her most popular original recipes! Honestly, the ease of putting these cakes together is a big draw.
The frosting is just as easy to make. Even better, pouring warm frosting over a warm cake means it practically frosts itself and keeps the cake so moist and delicious.

So go ahead and whip yourself up a lemon Texas sheet cake for your next party. Maybe make a white Texas sheet cake one too while you’re at it. I mean they are easy, delicious and fun to share!
What are your favorite Texas sheet cake flavors? Or maybe there’s a flavor you’d like to see made into a sheet cake? That might be a fun challenge!

Can I use full fat buttermilk instead of the sour cream, same amount?

I haven't tried it, but that should work well.

Made this cake today and just scraped it all into the trash. Way too much lemon extract...leaving a nasty aftertaste. Luckily I tried this before serving to our card club group...epic fail!

@Carlee, I used McCormick's Pure Lemon Extract. The aftertaste was truly terrible.

I am sorry you didn't like it. I've never heard that complaint before, so I am wondering what kind of lemon extract you used. A teaspoon each in the cake and icing isn't really that much for a cake this size.

I grew up on chocolate Texas sheet cake and my grandma's house so it is full of fond memories for me, but it is fun to switch it up every once in a while!
