Peanut Butter Oreo Cake – chocolate cake layers, with an Oreo cream filling and peanut butter Oreo buttercream.
Peanut Butter and Oreos
It became a well-know treat thanks to the 1998 version of the Parent Trap with Lindsay Lohan, but dipping Oreos in peanut butter has been a thing in my house long before that. Because for me, peanut butter goes with everything and I’d like to think I’ve succeed at trying it with just about everything!
Peanut butter and Oreos are about as good of a duo as peanut butter and jelly, if you ask me! They were made for each other.
Peanut Butter Oreo Cake
Putting the two in a cake together was a no-brainer and something I should have done a long time ago! We can all thank my friend, Rosanna, for not letting up on this request and getting me to finally whip it up.
The elements of this cake actually aren’t new, it’s the combination that is. For the cake layers and filling, we’re using my Cookies and Cream Cake. The one change I made to the filling recipe is that we’re using Peanut Butter Oreos instead of regular. The Peanut Butter Buttercream is also a favorite of mine and is one I use on many of my cakes.
You’ll also notice that this cake is HUGE! I wanted to make sure I got the cake, cream filling, and buttercream in every bite, so I made this a six layer cake with a double batch of cake batter.
However, you don’t have to make a double batch of cake if you don’t want to. You can stick with a single batch of cake and follow my Cookies and Cream Cake recipe. If you do a single batch of cake, you have two options:
- Option 1: Split the three cake layers in half to get six layers, but they’ll be thinner layers (about half the size of the ones pictured).
- Option 2: Don’t split your layers and just use the Oreo cream filling between the two layers and the buttercream on the outside. If you do this, use a single batch of buttercream from the Peanut Butter Dream Cake instead of the one provided (which is a 1.5x batch of my peanut butter buttercream).
If you’re using a stand mixer and the bowl is smaller than a 6 qt, I’d recommend splitting the recipe in half and making it in two batches. When you try to double batches of batter in a smaller bowl, like a 5 qt., you won’t have enough room in the bowl to mix the ingredients evenly. This can result in uneven cake layers as they bake and sunken centers.
