Fluffy Peanut Butter Frosting

I made this frosting for my sister-in-law's birthday cake and it was a big hit. For a finishing touch, I sprinkled pulverized Butterfingers over the top, followed by a variety of cut up mini-candy bars piled up in the center.

Ingredients

½ cup unsalted butter softened
1 cup creamy peanut butter
3 tbsp whole milk or as needed
2 cups confectioners' sugar aka powdered sugar

Instructions

Place the butter and peanut butter into a medium bowl and beat with an electric mixer.
Gradually mix in the sugar, and when it starts to get thick, incorporate milk, one tablespoon at a time until all of the sugar is mixed in and the frosting is thick and spreadable.
Beat for at least 3 minutes for it to get good and fluffy. (Don't skip this step)
HINT: Be sure your cake is cool before frosting.
