Seven-Minute Frosting for Quick Coconut Layer Cake


This frosting is used on our Coconut Layer Cake but it can be used with many different kinds of cake.

Source: Everyday Food, March 2005


  • 3 large egg whites
  • 2 teaspoons light corn syrup
  • 1/2 teaspoon cream of tartar
  • 1/3 cup cold water
  • 1 1/2 cups sugar


  1. In a medium saucepan, bring 2 inches of water to a simmer.

  2. In a large heatproof mixing bowl, combine reserved egg whites, light corn syrup, cream of tartar, water, and sugar.

  3. Place bowl over simmering water (it should not touch water); with a handheld mixer, beat on high speed until stiff peaks form, about 7 minutes.

  4. Remove bowl from heat; beat 3 to 5 minutes more to cool. Use immediately.

    I love this frosting! I made it to ice a coconut cake I made for a good friend for her birthday. It was such a hit! I won't buy pre-made icing again, this is so easy to make.

    Made a bunch of cupcakes for a dessert buffet party I was having and was literally down to the wire trying to make frosting and ice the cupcakes. This seven minute frosting saved the day - without it I would have never gotten everything done in time. See pictures and more here

    Mrsfrog, in answer to your question, NO, you only store this at room temperature. Never ever in the refrigerator.

    in response to "jumpygrouch's" comment. I believe I've figired it out! If you go back to the cake recipe this frosting is used w/you'll see this seven minute recipe has 1/4 cup store bought lemon curd, whisked into it. this is just my brain trying to make sense of less egg whites. But, if this is the case then this frosting recipe would be less confused if called "seven minute lemon tart frosting" or somthing more creativly Martha inspired.

    This frosting is quite different from the 7-minute frosting listed for the White Cake with lemon curd filling, and I'm wondering if there's a typo in one or the other, as I can't believe they'd be that different since all you do is add coconut shavings to it after you've made the cake. For example, in this one, for 3 egg whites you have 1 1/2 cups sugar, and in the other it's 6 egg whites with the same amount of sugar...
