Poured Fondant Icing

Poured Fondant Icing is an all purpose confection used to ice sweet-breads, cakes, petit fours and napoleons.

What is poured fondant icing?

Not to be confused with Rolled Fondant, the sugar dough used to cover cakes, Fondant Icing is pourable and is used to glaze cakes and pastries with a thin sheen of sweetness.

True Fondant is, in fact, more candy than icing. Fondant is what you find in the middle of my all-time favorite candy, a Peppermint Patty. Making true fondant is an unforgiving process of controlled crystallization.

This is where simple, powdered sugar fondant icing comes in…

Even though I will readily admit that this simple Fondant Icing is not really a true fondant, and it honestly doesn’t have the beautiful sheen of a real fondant icing, it is a good compromise for the home baker who wants to make Petit Fours, Napoleons or a glazed Bundt Cake.

It tastes great, it’s easy to make and it’s very easy to use.

  • The icing should be thick enough to coat the back of a spoon.
  • Add more sugar if it’s too thin or more water it it’s too thick.


  • Pour the icing into a bowl and sprinkle a few drops of water over the surface. This will prevent the surface from drying out and forming a crust. Cover the bowl with plastic wrap.
  • Poured fondant icing can be held at room temperature for 2-3 days, refrigerated for up to a week and frozen for up to 3 months.
  • Pour the water off the surface of the icing before using.

Fondant Icing is used to ice Classic Petit Fours, napoleons and donuts.

If you love this recipe as much as I do, I’d really appreciate a 5-star review.

Poured Fondant Icing Recipe

Fondant icing is the perfect topping for Napoleons, petit fours, donuts and other pastries.
Prep Time10 minutes
Bake Time5 minutes
Total Time15 minutes
36 servings


  • 4 oz water (½ cup)
  • 3 oz light corn syrup (¼ cup)
  • ½ tsp vanilla extract
  • tsp salt
  • 20 oz confectioner sugar (5 cups)


  • Combine the water, corn syrup, vanilla and salt in a medium sauce pan, bring to a boil.
    4 oz water, 3 oz light corn syrup, ½ tsp vanilla extract, ⅛ tsp salt
  • Remove the pan from the heat and gradually whisk in the sugar.
    20 oz confectioner sugar
  • The icing should be slightly warmer than body temperature and the consistency of thick cream. If you dip a spoon into the fondant it should cover with a slightly translucent finish. Use the fondant immediately or store in the refrigerator, well covered.
  • If the fondant cools below 100°F, rewarm gently. If the icing gets too thick add a few drop of water at a time until it's thinned to the proper consistency. If it gets too thin, add a little more sugar.

I think your measurement of the sugar is off - you say 20 Oz (5 cups). But 5 cups is actually 40 Oz. So which is it?

Confectioner's (powdered) sugar weighs half as much as granulated sugar for the same volume. A cup of powdered sugar weighs 4oz.

@Eileen Gray, would this icing on top of a cake make the cake soggy?

No, this is a pouring fondant. You want to use Rolled Fondant for making decorative pieces.

I am going to try this recipe. Was curious if i can use this recipe to frost donuts and would i be able to freeze them? Thankyou

The easiest frosting for donuts is a simple powdered sugar glaze. Combine 2 cups (8oz) of powdered sugar with about 3 tablespoons of liquid. Could be lemon juice, water, milk. You can add a little vanilla extract to flavor the glaze. It should be the texture of heavy cream. Dip the donuts while they're still warm. I would freeze the donuts prior to glazing. Reheat the donuts in a low oven then dip them while they're still warm. You could freeze them after glazing but the icing would likely melt as they donuts defrost.
