This easy peanut butter Texas cake is perfect for feeding a crowd. It is made in a half sheet pan, so you can cut plenty of pieces and the batter comes together in a saucepan.
This fun sheet cake is full of peanut butter flavor. It is made in the Texas sheet cake style where you boil the butter and water on the stove, so there is no need for creaming or fussing to get it together.
Plus it is a great size for sharing, but don’t worry it will disappear quickly. I made it as one of the treats at Little Dude’s second birthday and thought it was time to remake the recipe, shoot some quick pictures and update the post a bit.
For one of Little Dude’s birthday cakes, I thought it would be fun to do a sheet cake with one of his favorite flavors… peanut butter! I loved the idea of making a sheet cake.
The fact that the cake isn’t as thick as a traditional cake makes it so people could just have a little bit if they wanted or as much as they please.
Added bonus: I could pile it high with white chocolate buttercream! A few sprinkles around the side and a birthday cake is born.

As you can tell from the pictures, this cake is also great with peanut butter icing. That makes it more like a classic Texas sheet cake.
One of our favorite parts about baking sheet cakes is they don’t take any special equipment. Just a sauce pan, a couple of bowl and the sheet cake pan.
No need for the mixer, which is good because I only wanted to wash it so many times for this one party! Plus there is the added bonus that you don’t have to bring your ingredients to room temperature.
This cake has been a hit every time I have made it. This most recent time one of my brothers took a bite and said it tasted like Reese’s cereal. It kind of does! But in a much softer cakier kind of way!
So if you are half the peanut butter fans we are, you should definitely give this cake a go. The size makes it perfect for a potluck, BBQ or party and the fact that in can go from idea to coming out of the oven in less than 45 minutes is nice too. So, what are you waiting for?

We really enjoyed the combination of the peanut butter cake and white chocolate frosting! It is gong to be hard to not make it for every birthday from here on out!!
Sounds like the Peanut Butter Texas sheet cake, but you only state a greased sheet pan, what size pan do you use? Thanks!
It's just like a Texas sheet cake! Sorry I wasn't very clear. I used my half sheet pan which measures about 12 x 18 x 1.
What size pan? It just states greased sheet pan—jelly roll pan, 9×13? Thanks!
What size pan? It just states greased sheet pan—thanks!
Peanut butter is one of my favorite flavors too, this cake sounds wonderful! Thanks for sharing at What'd You Do This Weekend?!
I think I might have a slight addiction to peanut butter. I didn't keep it in the house pre-LD because I couldn't trust myself with it! Now I am slowly getting used to having it around.
Thank you! It was a really good combination, I think it might be making regular appearances around here!
Me too! This combo of peanut butter and white chocolate was so good!
I hope you love it! I can't wait to see what you filled your plate with tomorrow.
Thank you! It really was quite delicious. It was an exhausting but fun weekend here, I hope you had a great one as well.
Wow, that looks so good! I don't know why, but a peanut butter sheet cake is one of those things I never thought about doing. Sheet cakes are always white, chocolate, or marbled in my world. I can't wait to try this new take!
I hope you love it as much as we do! We are kind of addicted to peanut butter around here though!
