PB Cupcakes
Today I’m sharing a recipe that will thrill peanut butter lovers everywhere. Peanut butter cupcakes with peanut butter frosting. Made from scratch with simple ingredients you already have in your pantry, these cupcakes are easy and scrumptious!
MY LATEST VIDEOS
One challenge with baking with peanut butter is that it tends to make baked goods dry. I made several tweaks to this recipe to avoid that. I used oil instead of butter, brown sugar instead of regular sugar, and used cake flour.
You can make your own cake flour by measuring out a cup of flour, removing a tablespoon, and replacing it with a tablespoon of cornstarch. That’s what I did.
When the cupcakes are done, they will have crinkly tops. They don’t raise up much, they stay flat (unless you overfill the liners). Perfect for adding frosting!
Peanut Butter Frosting
The creamy peanut butter frosting makes these cupcakes purely decadent. Honestly, I could have just eaten the frosting by the spoonful. It is so good! You just need 5 ingredients to make this amazing frosting:
- creamy peanut butter
- butter
- powdered sugar
- vanilla
- milk (or heavy whipping cream)
We always have these ingredients on hand, which may turn out to be dangerous!! I piped my frosting on using a large star tip, but you can just spread it on if you prefer.
If you love peanut butter, you should definitely add these cupcakes to your list!
