This crazy delicious Chocolate Peanut Butter Earthquake Cake will seriously rock your world!
Here’s the deal with this cake – it ain’t purtty.
It’s meant to look like a peanut butter earthquake has come in and wreaked havoc on an innocent chocolate cake. All the while, tasting super rich, moist and delicious.
I found it tasted best when it was served warm, a-la-mode style.
The cake is actually super easy to make, and a riff on the classic earthquake cake.
Just grab a chocolate boxed cake mix, prepare it according to the box’s instructions and pour into your cake pan.
Then combine some butter, cream cheese, peanut butter and powdered sugar and blend until light and fluffy.
Scoop by tablespoons right on top of the cake batter.
Cover the whole cake in creamy peanut butter blobs.
Blobs… it’s such a fun word to say.
Let’s get crazy and throw in some extra chocolate and peanut butter… shall we??
A few (few?) chocolate chips and peanut butter cups for the road please.
The blobs will slowly sink to the bottom as the cake rises up while baking. It takes a little longer to bake than your average cake mix, so have patience.
You’re looking for a slightly jiggly center, nothing that wobbles too much.
The top will have cracks and creases…
Basically looking like an earthquake destroyed your cake.
Throw a little more chocolate peanut butter cups on top. Mmkay?
The peanut butter blobs form a creamy sweet layer that’s ribboned throughout the moist chocolate cake.
No frosting needed.

Loved this recipe, but didn’t have a deep enough plan and it cooked over :(.

Courtney @ Neighborfood
This is so much fun! My aunt used to make a coconut earthquake cake, but I have to say this chocolate peanut butter one looks even better. Especially with ice cream. Isn’t everything better with ice cream?

The name of this is so appropriate because this cake is seriously rocking my world! I’d never have thought to drop blogs (it IS a fun word to say!) of cheesecaky goodness into a cake so that it would fall to the bottom and form that glorious runny layer. And girl, your photos are ridiculously amazing. I want to grab your pan of cake and eat the entire thing, with plenty of scoops of vanilla ice cream of course!
