Chocolate and Peanut Butter Cake By Gemma Stafford

Hi Bold Bakers!

It’s official – chocolate and peanut butter are a thing. The baking world has taken the famed Reese’s Peanut Butter Cup and transformed the happy couple into a flavor combination as beloved as chocolate and coffee or chocolate and hazelnut. What better way to celebrate this salty-sweet combination than with a big and bold Chocolate and Peanut Butter Cake?!

Chocolate and Peanut Butter Cake

For those of you who don’t know me, hi! I’m Gemma Stafford, the baker behind Bigger Bolder Baking. As a professional chef and Bold Baker to the core, my passion is taking over-the-top sweets and baked goods and making them both accessible while holding on to all of that wow factor. I’m very proud to be an ambassador for GoodCook, since I love all of their baking essentials including many things you’ll want to make this treat. This cake is a perfect example of that and actually a favorite in my house. In fact, this Chocolate and Peanut Butter cake was requested by my husband, Kevin to celebrate his birthday this year!

This style of cake is my favorite – it’s freeform and rustic, decorated with fresh fruit and the most lovely swirled peanut butter buttercream (thanks to my OodleTip piping bag). Whether you’re making it for a special occasion or for a big birthday, your friends and family will literally swoon for this delicacy.

The cake inside of my Chocolate Peanut Butter Cake is one of my go-to recipes as it’s beyond moist and chocolatey, a nod to good quality cocoa powder and the addition of strong coffee. That being said, the best part of this cake is what happens when it’s introduced to my Crazy Peanut Butter Frosting. This frosting is salty, sweet, light as air and crazy rich. Just like a Reese’s Peanut Butter Cup, this cake packs a chocolate punch while being sweet and salty in all the right ways. To take it up that extra notch, I top this cake with fresh raspberries. Can you imagine anything more festive?!
