Buckeye Cake

Do you know what a buckeye cake is?

Actually, let’s start a little smaller.

Do you know what buckeye candy is?

It’s essentially sweetened, buttered peanut butter (did you know you can butter peanut butter?) dipped in chocolate. I like to think of it as a cousin to the peanut butter cup.

So then, the buckeye cake?

Like a peanut butter cup, supersized, with the bottom layer of chocolate replaced with a dense chocolate cake.

I know. I’m excited too.

I actually first found this recipe around 5 years ago when I hadn’t been baking as a hobby for very long and never made it because it intimidated me. I was a girl of simple cookies, one bowl recipes, and if anything involved the stove? Nuh, uh, I wasn’t doing it. Also off limits were pie crusts, cheesecakes, and anything involving a thermometer.

I’ve learned a few things since then.

And I’m extremely happy I did. Because this cake is delicious. If you have any love, whatsoever, for the combination of peanut butter and chocolate, you need to get to know this cake.

Seriously. Time to make a new best friend.

  1. I am totally drooling all over myself right now. For real. That looks like the best cake ever! I mean, what beats peanut butter and chocolate? One question- how do you do the little “knots” in the icing? It looks so neat!

  2. JehanP & Julia – Thanks so much!

    Kathryn – The “knots” were actually a happy accident! I was going for having cute little dots on each spot where the piped lines crossed, but the melted peanut butter chips were thicker than I was expecting, so when I went in to pipe a dot, this trail of icing hung on from the top of the dot to the piping bag. To “cut” it off, I twisted the trailing bit around the dot, making sure not to add any additional pressure to the bag. It unintentionally made the cute little knot you see, so I continued doing it all over the cake! Glad you like it! :)
