Penuche Frosting Recipe

The name of this heavenly frosting refers to the length of time that the ingredients must be beaten continuously over simmering water. This results in a thick, fluffy consistency. It’s also fat-free!

How To Make Penuche Frosting

A delightful frosting with Italian roots! A delectable blend of sugar, butter, and vanilla extract which results in a heavenly fudge-like consistency with a slightly nutty and sweet flavor profile. Best to top off those bare cupcakes to spruce up your next bake.

Prep: 30 mins
Total: 55 mins


  • 3 large egg whites
  • 1 ½ cup superfine sugar, or strained sugar, take regular and strain it
  • ½ tsp cream of tartar
  • cup water
  • 1 tbsp light corn syrup, makes frosting smooth
  • 1 ½ tsp vanilla extract


  1. Fill the bottom of a double boiler with 1-inch of water. Bring rapidly to a boil, then reduce heat to maintain a simmer.
  2. Place egg whites, sugar, cream of tarter and water in the top of the double boiler, stirring to blend the ingredients.
  3. Set over the bottom of a double boiler, cover and cook for 1 minute.
  4. Remove the lid and stir again briefly.
  5. Using a pastry brush, brush sides of saucepan with water to prevent crystals from forming, cover and heat 30 seconds longer.
  6. Using a hand-held electric mixer, beat over simmering water for a minimum of 7 minutes, or until thick and fluffy.
  7. Add the corn syrup and vanilla and beat on medium speed for 2 minutes longer.
  8. Remove from heat.
  9. Empty into a stand mixer and beat on medium speed until the frosting cools and is very thick.
  10. If frosting is too soft, refrigerate for 30 minutes, then beat again.
  11. Note: If the weather is very humid, additional beating time may be required.
  12. This frosting is best used the day it is made.
  13. Yield: about 4 cups, enough to fill and frost two 9-inch layers; three 8-inch layers; the tops and sides of a 9x13x2-inch oblong cake; or a 10-inch tube cake
