This easy and peanut buttery cake is perfect for feeding a crowd. It is made much like a Texas sheet cake and would be good with that chocolate icing, but we love it with white chocolate buttercream for an extra special treat!
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.
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. There’s no waiting for the butter to soften to be able to cream it!

For a fun sweet and salty treat, try making peanut butter pie with a chocolate covered pretzel crust. Peanut butter popcorn or peanut butter chocolate chip cookies would be wonderful as well.
For a healthier treat, we love the peanut butter and yogurt fruit dip and it really doesn’t get much easier than that to make either! What are your favorite peanut butter treats?
