Peanut Butter Cupcakes with Peanut Butter Frosting
As you can tell by the title of these cupcakes, I like peanut butter. Both the cupcakes and the frosting are made with it to give you plenty of peanut butter flavor in every bite! The cupcakes are delicious on their own, with a moist crumb and a hint of peanut butter. But, the frosting adds that little extra flavor I expected in a peanut butter cupcake.
Peanut Butter Cupcakes Ingredients
Yes, it’s all about the peanut butter in this recipe. But, there are a couple of things to keep in mind with other ingredients.
Room Temperature Ingredients: Using room temperature ingredients (especially butter, eggs, and buttermilk) will help you get the best results when baking these cupcakes. Butter is at room temperature at 65°F. Don’t put it in the microwave to soften it; simply cut it up into small pieces and let it sit out if you forgot to take it out of the refrigerator.
Baking Powder: Double-check the date on your container of baking powder for freshness. Old baking powder can definitely affect baked goods.
Buttermilk: If you don’t have any on hand, make your own homemade buttermilk to use.
Confectioners’ Sugar: Also known as powdered sugar, you will notice that for the frosting, it should be sifted. Sifting the sugar breaks up any lumps there may be before mixing with other ingredients.
How to Make Cupcakes
Skip the boxed cupcake mixes at the grocery store and make your own, homemade cupcakes. It really does make a difference in the final product. And, making these cupcakes are not a lot of work! To get started, line muffin tins with cupcake liners. I was able to get 20 cupcakes made from this recipe. Set the lined tin(s) aside.
In a bowl, whisk together the flour and baking soda and set that aside. Using a hand mixer, cream the butter and sugar in a large bowl until fluffy. Next, beat in the peanut butter and vanilla. Add the eggs, one at a time. Finally, starting and ending with the flour mixture, alternately add the flour mixture and buttermilk.
Fill each cup of the muffin tin about 2/3 of the way full with batter. (I like to use a 1/4 cup ice cream scoop.) Unless you have a large muffin tin, you will probably need to use two tins. Bake the cupcakes for about 20 minutes, rotating the tins halfway through baking them (unless you are baking the cupcakes one muffin tin at a time). The cupcakes are done when an inserted toothpick comes out with a few crumbs, but no wet batter. Let the cupcakes cool before adding the frosting.
How to Make the Frosting
The peanut butter frosting really brings out the peanut butter flavor that one would expect from peanut butter cupcakes. To make the frosting, simply beat the sifted confectioners’ sugar, butter, peanut butter, heavy cream, vanilla, and salt. Beat on high speed until light and fluffy. Spread a thin layer of frosting on top of the cupcakes and enjoy! Store the frosted cupcakes in an airtight container for up to two days at room temperature.
