Peanut Butter Cupcakes – peanut butter fans rejoice, these are the perfect cupcakes for you! They are soft, tender, and topped with a decadent peanut butter frosting.
Not going to lie, I simply can’t resist a good peanut butter treat. Reese’s Peanut Butter Cup Cookies and Peanut Butter Sheet Cake are two more treats I absolutely love!
Peanut butter is a staple at my house. We eat it on toast, on celery, on crackers, in PBJ’s, and sometimes by the spoonful. My boys will even eat it on carrots!
With our affinity for peanut butter, we of course love it in baked goods and treats. I finally got around to trying peanut butter in cupcakes, and I’m sure glad I did. These cupcakes were a huge hit with everyone in the family.
They start out moist and flavorful, but then they are topped with an incredible frosting. If you’ve never tried peanut butter frosting before, you are missing out! It is so yummy that you will want to eat by the spoonful. Just make sure you don’t eat too much – you want some left for the cupcakes!

What can I use instead of cake flour?
If you don’t have cake flour, you can make your own! Measure out a cup of all purpose flour, remove a tablespoon of it, and replace it with a tablespoon of cornstarch. That’s what I always do because I rarely have cake flour on hand.
What can I use instead of buttermilk?
If you don’t have buttermilk, you can substitute 1/2 cup of sour cream + 1/2 cup milk. Or you can make a substitute by adding a tablespoon of lemon juice or vinegar to a 1 cup measuring cup, and adding milk till you get a cup. Let it sit at room temperature for a few minutes till the milk curdles.
