Peanut Butter Cupcakes with Banana Buttercream ~Sundays With Joy~

Before we get to today's Peanut Butter Cupcakes with Banana Buttercream... I need to announce the winner of the KitchenAid Hand Blender giveaway! Drum roll please.............................


Congrats Tammy email me at at your earliest convenience!

Now lets talk about Joy the Baker's Peanut Butter Cake.

I just could not justify making an entire 2 layer cake. My new unprocessed lifestyle is still going strong. I'm doing well with only a few slip ups here and there. Between that and going meatless. I've lost five lbs. My weight has been up and down 10lbs all year. I am determined to stay at this weight. And I'm sorry... peanut butter cake is not going to help the cause!

SO instead of a 2 layer cake, I opted to cut the recipe in half and make cupcakes instead. In my head I thought this would help me have more self control. Well let me tell you something. These cupcakes were just so gosh darn good. I couldn't. I had 2 right off. And I probably would have had another if my trouble making dingo dog didn't get to them first.... I have no idea how a 25-30lb dog can eat so much! 9 cupcakes she ate NINE! Why can't I have her metabolism?!

The cake was perfectly peanut buttery, dense, and moist. Joy paired her's with a  peanut butter cream cheese frosting. (Recipe can also be found in her book) I love peanut butter cream cheese frosting. I have made it for years.... and I am pretty sure peanut butter cream cheese frosting is why my husband married me! Every year I make him a chocolate cake with it for his birthday. It's also my mom's favorite!

Here is the sad part. I had no cream cheese and I was running low on peanut butter after making the cake. So what's a girl to do? First instinct was to make a chocolate frosting. Problem number two. I had no chocolate in the house. Can you tell I'm trying to loose weight?! NO chocolate!!!!!!

I had some overly ripe bananas waiting for me to make some pancakes, muffins, or a bread. It dawned on me peanut butter and banana are a match made in heaven.

Though I was unsure... can I make frosting out of a banana?? Why not?!

It worked perfectly! So so so so so good on top of these cupcakes.

 I made no adaptions to Joy's cake recipe other than cutting it in half and making cupcakes. So if you want to get that recipe..... you need to snag a copy of Joy the Baker Cookbook: 100 Simple and Comforting Recipes!

I think someone was trying to be patient why I had a cupcake photo shoot... the life of a blogger is hard on her kids...

Don't fret.... I am going to share my banana frosting recipe!

Banana Buttercream Frosting


1/4 a banana
4 tbs of room temperature butter
2-3 cups of powdered sugar
1/4 tsp vanilla bean paste
1/4 tsp salt


In the bowl of an electric mixer with your whisk attachment. Cream butter and banana together. Add in salt, and vanilla, mix on medium/ high. 

Slowly mix in sugar 1/2 cup at a time or until you get your desired texture/stiffness.   Pipe onto cooled cupcakes or cake. 

Makes enough frosting for 12 cupcakes or 1, 8 inch layer cake.

  1. Congratulations on your success with the unprocessed foods, Carrie! You are a MUCH stronger woman than I am. Living that structured lifestyle would be SO difficult for me.
    I'm all about portion control though, so your cupcake idea is awesomesauce!

    1. It's tough but I feel so much healthier. I'm not going super crazy, there are somethings I just can't live without!

  2. Yum, banana frosting, that sounds amazing. And congrats on the weight loss! You're amazing! I am having SO much trouble. :)

    1. There are just 10 pesky pounds that I need to keep at bay. Blogging does not help! LOL

  3. Look at those cupcakes... and that buttercream... I WANT!

  4. I'm SO happy to see this with real bananas! There's nothing I abhor more than "banana essence" I will definitely have to give this one a try!

    1. I know ! I bet people normally would have used an extract. The real banana makes it slightly lighter because you can cut the butter down. WIN!

  5. Carrie,

    Your cupcakes look fabulous, love the shot with your son waiting patiently, never taking is eye off the cupcake, too too adorable. I have to try your banana frosting!


  6. Can I use vanilla extract if I can't find vanilla paste? What's the difference?

    1. Yes you can I would use 1 tsp vanilla extract in it's place. I like the paste because it's filled with vanilla bean specs.

  7. Can I use vanilla extract if I can't find vanilla paste? What's the difference?
