Chocolate Peanut Butter Cup Cake

So we like to do a lot of cakes around here. I mean A LOT! We have about 4 birthdays within a 2 month time frame with my kids. Now I like to do two different cakes usually for my older ones because they have a friends party and then a family party. So this mama usually has her work cut out for her, but you guy’s is it really work when you love what you do? I don’t think so, so let’s just call it fun.

Now if you remember this Stranger Things cake, that was my now 11 year olds friends party cake. This Chocolate Peanut Butter Cup Cake was for the family party. This cake is so moist and rich and flavorful, it is literally the chocolate and peanut butter lovers dream. I could eat this cake all day long and not get sick of it, but in reality I probably could do that for any cake, but let’s just keep that little bit a secret between you and I, okay?

I used the same chocolate cake recipe for this as I did for my Chocolate Cherry Amaretto Cake that we loved so much. We love that chocolate cake and like to use it over and over with a lot of different variations. This time being this Chocolate Peanut Butter Cup Cake.

If you love peanut butter cups then this cake is absolutely for you. It is stuffed and frosted with a delicious peanut butter buttercream and topped with a smooth and silky ganache. Then studded with peanut butter cups. I tried to get the illusion of an actual peanut butter cup for this cake with the ganache topping the peanut butter. I think it turned out really well actually!

Usually I’m more of a vanilla cake girl, but when you pair chocolate with peanut butter I’m a sucker. I mean who isn’t. There are people in this world I found out that don’t really like the two paired together….um, really?!?! I mean I’m not the hugest peanut butter fan when it’s all by itself. Like you won’t ever see me just eating a peanut butter sandwich or anything. But put the stuff in a dessert as a filling or a frosting and I’m sold.

So if you want that perfect birthday cake, holiday cake or just because cake (we all need a just because cake) then this Chocolate Peanut Butter Cup Cake needs to be on our must make list this year. I promise you it will not disappoint!
