Milk Chocolate Glaze
1 cup (6 ounces) milk chocolate, chopped
1 tablespoon unsalted butter
1/4 cup heavy whipping cream
In medium microwave-safe bowl, heat chocolate and butter at 50% power until completely melted, about 2 minutes; stir to combine. In small bowl, heat cream for 10-15 seconds. Add cream to chocolate; stir slowly until completely smooth. Let glaze sit at room temperature for 5-10 minutes.
To glaze cupcakes, dip the top in warm glaze; shake off excess chocolate. Allow chocolate to set before serving. If desired, garnish with chopped peanuts.
