How to Thicken Frosting With Cornstarch (5 Steps)

Holes in the icing on a cake could indicate you used a frosting that was too thin. Use cornstarch to thicken the leftover frosting for recovering the cake. Cornstarch is an effective thickening agent for cake frostings, but this starch cannot be used raw. To activate the cornstarch, you must heat it in liquid before adding it to your frosting. For cake frostings, opt for milk as the warming liquid for the cornstarch; the natural sweetness in the milk will enhance the flavor of the frosting.

Things You'll Need

  • Whisk
  • 1 cup milk
  • 2 tablespoons cornstarch
  • Saucepan
  • Bowl
  • Plastic wrap
  • Thin frosting
  • Mixer

Instructions

  1. Whisk together the milk and cornstarch in a saucepan over medium heat.

  2. Heat the mixture until it begins to boil and thicken, whisking the entire time.

  3. Remove the cornstarch and milk mixture from the heat and transfer it to a bowl.

  4. Cover the thickening mixture with plastic wrap directly in contact with the surface to prevent a skin from forming. Cool the mixture to room temperature.

  5. Beat with a mixer on medium-high speed the cornstarch mixture into the thin frosting in 1/4 cup increments until the frosting reaches the desired consistency.
