    Instructions

      Chocolate Cupcakes

      1. Preheat the oven to 400 degrees F. Line 2 standard cupcake pans with 18-20 liners. Set aside.
      2. In a mixer fitted with a paddle attachment, or using a hand mixer, cream butter until smooth. Add the sugars, eggs, and vanilla and mix until fluffy, about 3 minutes. Add the cocoa, baking soda and salt; mix well.
      3. Add one cup of flour, then half the sour cream and mix. Repeat with the remaining flour and sour cream. Slowly add the hot coffee and mix until smooth. The batter will be thin.
      4. Fill cupcake liners ⅔ of the way. Place tins in the oven and drop the temperature to 350 degrees F. Bake 15-18 minutes, checking at 15 for proper doming. Cupcakes are done when a clean toothpick inserted in the center comes out clean.
      5. Remove from oven and allow to cool in pan for 10 minutes, then move to cooling rack. When cool, use a cupcake corer or small knife to make a well in the center of each cupcake.

      Hot Fudge Sauce

      1. Heat the chocolate in the microwave in a microwave-safe bowl, whisking every 20 seconds, until melted and smooth, 1-3 minutes. Whisk in cocoa until combined. Set aside.
      2. In a small saucepan set over medium heat, combine corn syrup, sugar, cream, milk, and salt. Bring to a simmer, stirring frequently, until thickened, about 3 minutes.
      3. Remove from heat and whisk in butter and vanilla. Cool the mixture slightly (2 minutes or so,) then whisk in the melted chocolate mixture until smooth. Set aside.

      Peanut Butter Mousse

      1. In a chilled bowl, whisk the heavy cream until soft peaks form. Set aside in refrigerator until ready to use.
      2. Using a hand mixer, in a separate bowl, beat cream cheese and peanut butter until combined. Add milk and vanilla and mix until smooth. Add sifted powdered sugar and mix until combined and creamy, about 3 minutes.
      3. Fold half of the whipped cream into the peanut butter mixture until just combined, then add the rest and fold gently until combined and fluffy. Refrigerate at least 1 hour before using.

      Assembly

      1. Using a butter knife, "paint" the outer edge of each cupcake with some cooled hot fudge sauce. Dip the wet edges in sprinkles or chopped peanuts and set on a baking sheet to dry.
      2. Spoon hot fudge sauce into a piping bag and fill each cupcake to slightly overflowing.
      3. Fill a second piping bag (fitted with a star tip) with Peanut Butter Mousse and swirl on top of each cupcake, on the inside of the garnished edges.
      4. Top each cupcake with a drizzle of more hot fudge, sprinkles, peanuts, peanut butter cups, and a cherry. Serve with tall glasses of milk and enjoy!
