Equipment

  • 1 Electric Hand Whisk or standalone mixer

Ingredients

  • ½ cup Butter - vegan, or use margarine, very soft
  • 2 cups Icing Sugar
  • ½ cup Peanut Butter
  • 2 tsp Vanilla Extract
  • Pinch Sea Salt

Instructions

  • Place the butter and peanut butter into a large mixing bowl and beat well until soft and creamy.
  • Sift over the icing sugar and very slowly mix. I like to start this step by hand because the icing sugar billows up into the air and then it's just a whole new clean up job!
  • Beat the icing into the butter mixture until thoroughly mixed. Add in the vanilla extract and pinch salt.
  • If the mixture isn't quite thick enough, add a little more icing sugar, ¼ cup at a time, until you reach the desired thickness.
  • Icing will set up on standing or when refrigerated, but is easily spreadable at this stage.
  • Will keep stored in the fridge, covered, for up to a week.

Please note that where the recipe asks for milk, butter or yogurt, this refers to any plant-based version that you prefer.
