Equipment

  • Handheld Mixer
  • Rubber Spatula
  • Measuring Spoons

Ingredients

  • 8 ounces salted butter room temperature
  • 8 ounces unsalted butter room temperature
  • 1 14 oz can sweetened condensed milk
  • 1.5 tsp. vanilla bean paste or vanilla extract

Instructions

  • Combine the room temperature salted and unsalted butter into a mixing bowl.
  • Using the handheld mixer, whisk or beat the butter until it is whipped. The butter will look lighter in color and take up more room in the mixing bowl.
  • Add in the vanilla and mix for a few seconds, or until fully incorporated.
  • Fold in about a 1/3 of the can of sweetened condensed milk and whip until incorporated. Then, repeat with each third of the sweetened condensed milk until all of it is added into the frosting.
