Vanilla Buttermilk Cupcakes with peanut butter frosting

My husband just celebrated another birthday. He doesn't want me to discuss his age but all I can tell you is he is currently a couple years older than me. He doesn't think I'm funny and reminds me in a couple of months that he is now only one year older than him. My husband loves Superman but I didn't have any matching liners so we went with the next best thing....Spider-Man. He loved the cupcakes and frosting. I used this peanut butter frosting recipe with chopped fine pieces of peanut butter cups mixed into the frosting.

Vanilla Buttermilk Cupcakes
12 oz. unsalted butter, softened
1 cup sugar
1 large egg
2 egg whites
2 tsp vanilla extract
1 1/2 cups cake flour
3/4 tsp baking powder
1/2 tsp baking soda
1/2 tsp salt
3/4 cups buttermilk

Directions:

1. Preheat oven to 350 degrees F.
2. Line a muffin tin with cupcake liners.
3. In a large bowl, cream the butter and sugar until fluffy.
4. Scrap down the sides of the bowl before adding the egg. Mix until just combined.
5. Add the egg whites and mix until combined.
6. In a medium bowl, whisk together the cake flour, baking powder, baking soda, and salt. 
7. Add 1/3 cup of the flour mixture to the butter mixture and mix until incorporated.
8. Add 1/4 cup of buttermilk and mix.
9. Add another 1/3 cup of flour and mix before adding another 1/4 cup of buttermilk.
10. Add the remaining flour mixture and then the rest of the buttermilk. Mix until combined.
11. Fill the cupcake liners 3/4 full of batter.
12. Bake the cupcakes about 18 minutes or until golden brown.
13. Allow the cupcakes to cool before removing from pan and allowing to fully cool on a wire rack.
