Gourmet Peanut Butter Cupcakes

1 box (18 oz.) chocolate cake mix
1 cup Hellmann’s® or Best Foods® Real Mayonnaise
1 cup water
3 eggs
1 (12 oz bag) Reese’s miniature peanut butter cups, unwrapped
1 cup butter, softened
2 cups Creamy Peanut Butter
4 cups powdered sugar
6 Tablespoons milk, or more if needed

Preheat oven to 350. Line two 12-cup muffin pans with cupcake liners; set aside.
Beat cake mix, Hellmann’s® or Best Foods® Real Mayonnaise, water and eggs in large bowl with electric mixer on low speed 30 seconds. Beat on medium speed, scraping sides occasionally, 2 minutes. Scoop or spoon into prepared muffin cups.
Place one Reese’s peanut butter cup into the center of each cupcake.  Press the peanut butter cup into the batter so 2/3 of the peanut butter cup is covered with batter.  The peanut butter cup will sink further in the cupcakes as it cooks.

Add half the sugar and half the milk to the butter mixture.  Mix until blended.
Add the remaining sugar and milk.  Mix until blended and the beat with mixer for 3 minutes until nice and fluffy.  Add more milk if needed to received desired consistency.
Pipe frosting onto cooled cupcakes.  Cut remaining peanut butter cups in half.  Place 1 half on top of each cupcakes
