These Chocolate Peanut Butter Cupcakes are drizzled with dark chocolate and topped with a peanut butter frosting. They’re perfect for when you’re in the mood for a decadent treat.
If you’ve been following Let’s Eat Cake, you know that we’re huge fans of the classic combination. We’ve made Chocolate Peanut Butter Fat Bombs and Chocolate Peanut Butter Overnight Oats before, but I thought it was about time we made something truly sweet!
There are a few things in this world that I simply can’t resist. Cotton candy, stopping to stare at the stars on clear nights, and the combination of chocolate and peanut butter.
What I also love about this recipe is that it’s so easy. The chocolate cupcake base just uses three bowls and you won’t need the electric mixer for the cake portion.
And, the peanut butter frosting has that super rich peanut butter flavor because it combines peanut butter with heavy cream, vanilla, powdered sugar, and a dash of salt. I did mention these were decadent, right?
What Type of Chocolate Is Best?
To make these cupcakes, I first created a rich chocolate cake base using Dutched cocoa and Private Selection 62% chocolate.
You can use any % of chocolate you want (including milk chocolate), but I prefer to choose a chocolate chip or chunk that has a higher cacao percentage. Since I’m already adding sugar to the recipe, I believe this helps the chocolate flavor stay front and center.
I’m a big fan of Private Selection chocolate – it’s always available at Ralphs, part of the Kroger Family of Stores, at a reasonable price and it tastes like the pricier Belgian chocolate chips that I have to special order. Quality and convenience makes it a win-win for me.
What Type of Cocoa Powder Should I Use?
No matter what chocolate chip percentage you choose, it’s imperative that you use Dutched cocoa powder. When you’re at the store (or hunting around in your pantry), look for cocoa powder that says Dutch-processed or processed with alkali. This is critical. Without it, your cupcakes will sink and be sad and you’ll be mad at me.
It happened to me. On repeat. I wasn’t paying attention and couldn’t figure out why my cupcake recipe was not working! Batch after batch of chocolate cupcakes rose in the oven and sank in the middle. Turns out it was the cocoa I had been using.
I didn’t realize when I had changed cocoa powders that I had started using a non-alkalized cocoa. This is the cocoa powder I used for this recipe. It combines both types, is great if you can’t find cocoa that’s entirely Dutch processed, and results in a darker, fudgier chocolate cupcake. Which just happens to go perfectly with peanut butter frosting.
Here are a couple quick tips on how to make these the best chocolate cupcakes ever!
- You all know how much I love my stand mixer, but you don’t actually need it for the chocolate cupcake base! Instead, you’ll need just three bowls: two medium or large bowls (one for dry and one for wet), and one small bowl (to mix together the chocolate and boiling water).
- Use Dutched cocoa powder or one that combines Dutched and non-Dutched. I don’t want your cupcakes to sink!
- For pretty piping, use a 1M Wilton tip or an 825 Ateco open star tip. I used the latter for these cupcakes.
- To apply the drizzle without making a giant mess, place the cupcakes on a baking sheet and wave a chocolate-filled spoon over the top.
- Bake your cupcakes until they bounce back just slightly when touched or when a toothpick inserted into the center comes out clean.
