A PB Lover’s Dream
This recipe will thrill peanut butter lovers everywhere. Peanut butter cupcakes with peanut butter frosting is a peanut butter lovers dream! Made from scratch with simple ingredients you already have in your pantry, these cupcakes are easy and scrumptious!
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.
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!
How to make Peanut butter cupcakes
DRY INGREDIENTS. In a small bowl, whisk together the cake flour, baking powder, baking soda, and salt. Set aside.
WET INGREDIENTS. In a large mixing bowl, whisk the oil, peanut butter, and brown sugar till smooth. Add the eggs, buttermilk, and vanilla and whisk till well blended.
COMBINE. Stir in the dry ingredients just till combined. Don’t over-mix.
BAKE. Spoon batter into paper lined muffin pans, filling just over half full. Bake at 350° for about 15 minutes or till a toothpick comes out clean. Cool cupcakes completely, then frost.
