Decadent Chocolate Cupcakes with Peanut Butter Frosting!

A moist chocolate cupcake with a creamy-peanut buttery frosting.

It appears that winter has finally arrived in our neck of the woods.  The temperatures are expected to drop into the single digits this weekend!!! As I write this post a wintry mix of sleet and snow has caused many of our local schools to close or be delayed.  The good news is, we’ve had plenty of time to prepare for the bad weather.


Michael has the shovels and snowblower ready. And me? Well, I’ve stocked up the freezers and pantry with plenty of ingredients for all the comfort foods we love when we are stuck indoors!

Like these Decadent Chocolate Cupcakes that I made yesterday morning!

A favorite of both Michael and I, especially with that creamy peanut butter frosting!


The recipe I use is actually for a cake. But several years ago I decided to change it up a bit and make cupcakes. They worked out so well, I never made the cake again!!! LOL!

Like most cakes, you start by creaming the butter and sugar together. Then add in the eggs, one at a time.

This recipe calls for regular cocoa but I’m a huge fan of dark chocolate so I use it instead.

**UPDATE: To enhance the chocolate flavor even more-substitute the water for coffee!

TIP: To avoid flour flying everywhere, I turn my stand mixer on low and then I alternate between adding in the wet and dry ingredients. 

As for the peanut butter frosting? Well, I use one of my FAVORITE Baking Guru’s recipe-Ina Gartens, and I’m not ashamed to admit it. It’s the perfect creaminess with just the right amount of peanut butter flavoring.

I hope you enjoy this recipe for Decadent Chocolate Cupcakes with Peanut Butter Frosting!

  1. Yum to Cupcakes these look great, that peanut butter frosting sounds amazing. But I have to say single digits burr, I would probably just go hide in the closet with a batch of those cupcakes and wait for spring to arrive. Can you guess I’m just not a fan of cold weather.

  2. I have been trying hard to eat healthy. These chocolate cupcakes looks so amazing. I am going to have to break down and give myself a treat. LOVE LOVE these cupcakes.

    1. I hear you, Diane! I started the new year off making a MAJOR goal to lose weight, and get healthy, but darn it if I make these treats for hubby and of course, have to sneak a bite!! Blessings to you, sweet friend!
