Chocolate and peanut butter is a delicious and classic flavor combination
This Chocolate Peanut Butter Pretzel Cake is nothing short of delicious. It features moist chocolate cake, peanut butter buttercream frosting all over, and slightly salty pretzel buttercream between layers.
Posting about this cake is long overdue
I actually made and photographed this cake more than a year ago: it was my birthday cake in May 2019. For no particular reason, I just let it sit around in my blog draft posts for a while. It's a shame, too, because the cake was 10/10 delicious.
My 33rd birthday came and went last month without much fanfare. I didn't make anything for myself. It's not that I wouldn't have liked to. But I found myself a little busier than usual, as we ended up bringing our newborn son home from the hospital on the day before my birthday.
Best. Birthday present. Ever.
Anyway, here we are. And it's time to share this cake with you all.
What inspired this recipe?
The recipes for the chocolate cake and and peanut butter buttercream come straight from Joy Wilson’s cookbook, Homemade Decadence: Irresistibly Sweet, Salty, Gooey, Sticky, Fluffy, Creamy, Crunchy Treats. The pretzel buttercream is based on Joy's buttercream recipe, too, but you won't find it verbatim in that cookbook.

Because who doesn't want more cake?
If we're talking about cake, we need to talk about this Double the Chocolate Cake. You don't want to pass it up.
However, if you're looking for something in a smaller size, check out these Hot Chocolate Cupcakes, Lemon Poppy Seed Cupcakes, and Beet Red Velvet Cupcakes! Double Chocolate Brownie Cupcakes are pretty great, too.
What about recipes featuring peanut butter + chocolate?
I have a Peanut Butter Marshmallow Pie with a pretzel crust that's really good that you should definitely check out. It's topped with chocolate chips, mini marshmallows, and salty peanuts. There's also a No-Bake Chocolate Peanut Butter Pie that's great. Both of these are frozen sweets.
And! Let's not forget about this crazy good Peanut Butter Cheesecake with Dark Chocolate Ganache!
