*These chocolate peanut butter cupcakes made with Reese’s peanut butter taste just like a Reese’s peanut butter cup! They even have a little peanut butter surprise inside!
Chocolate Peanut Butter Cupcakes
If you know my husband, you know that one of his favorite foods is peanut butter. Most of his favorite desserts include peanut butter so it was only fitting to make some Reese’s chocolate peanut butter cupcakes to celebrate his birthday.
These chocolate cupcakes are a variation of these peppermint mocha cupcakes, but I used less instant coffee. Using coffee in chocolate cupcakes enhances the chocolate flavor without giving it the taste of coffee.
The peanut butter frosting is a variation of my vanilla buttercream recipe. It’s super creamy and when you use Reese’s peanut butter, it tastes just like a Reese’s peanut butter cup! I typically use salted butter, but peanut butter is already salty, so I used unsalted. Also, make sure you use butter and not margarine. Margarine gives a weird, broken up consistency.
