Yellow Texas Sheet Cake with Peanut Butter Icing
There’s something I just love about a Texas sheet cake. Maybe it’s the way it feeds a crowd, or how it always feels welcome at potlucks, parties, and holidays. But one thing’s for sure: when you show up with a Yellow Texas Sheet Cake topped with rich peanut butter icing, you’re walking in with the unofficial dessert MVP.
This cake is tender, buttery, and deeply nostalgic. It bakes up fast in a big pan, gets slathered with warm, pourable peanut butter icing, and sets into a dreamy, fudgy topping that coats every inch of the cake.

What Makes a Sheet Cake “Texas Sheet Cake”?
Texas sheet cake is famous for its flat shape, quick baking time, and pour-on-while-warm icing. I LOVE a chocolate Texas sheet cake – it was something my mom made often growing up, and this yellow Texas sheet cake with peanut butter frosting is its golden cousin. It still follows the same principles: simple ingredients, big flavor, and a frosting that almost sinks into the top of the cake as it cools.

Supplies Needed for Yellow Texas Sheet Cake:
Butter Vanilla Baking Emulsion – You can easily substitute this with butter and vanilla extracts (or even just vanilla!) but this LorAnn Butter Vanilla emulsion is so sweet, butter, and delicious! It is a pantry staple that I always have on hand! In addition to ordering on Amazon, you can also find it at Hobby Lobby and Walmart (in the parry/cake supply aisle, not the baking aisle).
Jelly Roll Pan – This is a staple pan size for my kitchen. I love Texas Sheet Cakes and can’t wait to try other flavor variations!
Mixing Bowls – Any mixing bowls will do! But these Pyrex Essentials bowls are my favorite.
Preheat oven to 375 degrees. Lightly grease a 10×15 in jelly roll pan. Set aside.
In a medium saucepan, add salted butter and milk. Turn on medium-low heat. Heat until simmering.
While your butter and milk are coming to a simmer, mix flour, sugar, salt, and soda in a large mixing bowl.
Pour butter and milk over dry ingredients, whisk together until combined.
Add sour cream, eggs, and extract to cake batter. Mix until combined.
Pour cake batter into lightly greased pan. Bake for 15 minutes.
While cake is baking, make your fudgy peanut butter icing. Add butter, peanut butter, and milk to a saucepan and heat over medium-low heat until simmering, mixing frequently.
Ingredients for peanut butter icing
Once simmering, remove from heat. Whisk powdered sugar and extract into peanut butter mixture. Whisk vigorously until icing is fully combined, using electric beaters if necessary. All your powdered sugar should be combined with no clumps remaining.

This is amazing! I didn’t have the vanilla butter emulsion so I used vanilla extract and a little dash of rum extract. It tastes like a scotcharoo bar in cake form. I could use double the amount of frosting though as that is delectable 🥰
Thank you so much for that kind feedback! We love the icing too, and Rum extract sounds like an amazing substitute- We are going to have to try that!
