The classic peanut butter and jelly sandwich flavors in cupcake form! Peanut Butter and Jelly Cupcakes are a vanilla flavored cupcake with a jelly filling and creamy peanut butter frosting.
Preheat the oven to 350 degrees. Line a 12 muffin tin with paper cupcake liners.
In a large bowl, sift together the flour, baking powder, and salt, and set aside.In a separate bowl, cream together the butter, sugar, and vanilla with an electric hand mixer.
Add the eggs, one at a time, beating well after each addition, then add the milk.
Slowly add the dry ingredients to the wet ingredients and mix on low speed until the cupcake batter is uniform. Do not overmix.
Fill each cupcake liner halfway with batter. Drop a tablespoon of the jam in the center of the cupcake and then top with more batter so they are a little more than three-quarters full.
Bake for 20 minutes or until the cupcakes spring back when touched lightly. Let them cool completely before icing with Peanut Butter Frosting.
For the Frosting
In a large mixing bowl, use an electric mixer to whip the butter and peanut butter together.
Add the confectioners’ sugar, salt, and then the milk. Add additional tablespoons of milk or sugar to loosen or tighten the icing, respectively.
