Boiled Icing

I asked my mom to share some of her old recipes from her “black book” with me when I was writing my first cookbook. Sharon’s Boiled Cake Icing is what she gave me.

I remember her making this frosting when I was a kid. This frosting has a consistency, unlike any icing you will find in a grocery store.

Not that there is anything wrong with store-bought icing. There’s just something about homemade cake icing that tastes better.

This cake icing recipe is no different. And since it is boiled, the consistency is out of this world, almost like a meringue or melted marshmallow.

    This is my favourite icing to make. Very simple to make and is very much like marshmallow. I only make this recipe now instead of buying store bought icing.

    My mother made for every special occasion, an Angel Food cake with boiled icing
    or seven minute icing (tinted pink) She would leave the iced cake sitting out over night with no covering. It would have a very thin “crust” when she served it.
    How did she do this? I have tried for 15 years since she passed to copy this. I tried both recipes, heating the sugar water above 238 degrees, beating icing longer, etc. Can you help?

    1. Not sure what exactly you are asking. All I know is this recipe has been in my family for over 50 years and is delicious!

    Hi, will the corn syrup in this recipe prevent the icing from crusting? I’ve tried other boiled icing recipes without the corn syrup but they turn matte and crusts after a few hours of sitting at room temperature.

    1. It should stay fluffy for a couple of days. I recommend keeping the cake in the refrigerator.

  4. Donna says:

    One question please. Why the addition of corn syrup when making this kind of frosting? Thanks!

    1. To give it a thick consistency and a little flavor. This icing has a similar consistency to a melted marshmallow.
