Splenda Icing and Frosting

Chocolate Icing

Many people are turning to Splenda to lower the sugar in their icing. Making icing with Splenda (sucralose) is an excellent way to decrease sugar and calories.

Splenda Frosting Recipes

Splenda cannot be directly substituted for powdered sugar in icings and glazes, because the texture will not be the same. The following recipes provide step-by-step instructions for making sucralose frosting.

Orange Glaze

This recipe creates a delicious glaze icing for Bundt and angel food cakes. It does not need to be refrigerated. It should be used immediately, and will keep on the cake for five or six days.


  • 1 1/2 cups Splenda granular sugar substitute
  • 1/4 cup cornstarch
  • 5 to 6 teaspoons fresh squeezed orange juice, strained
  • 1 teaspoon orange zest


  1. Combine Splenda and cornstarch in a blender.
  2. Blend on high speed until well-combined.
  3. Pour into a small bowl.
  4. Add orange juice and orange zest. Stir until well combined.
  5. Pour over cake.

Splenda Chocolate Frosting

This sugar-free chocolate frosting is perfect for cakes, brownies, and cupcakes. The frosting needs to be used right away to ice the cake. The cake should then be refrigerated, and will last three to four days.


  • 2 ounces unsweetened chocolate, melted and cooled
  • 1/3 cup heavy whipping cream
  • 1/2 cup unsalted butter (softened)
  • 4 tablespoons granulated Splenda
  • 1 teaspoon unsweetened cocoa powder
  • 1 teaspoon vanilla


  1. Place melted, cooled chocolate in a mixer bowl.

  3. Change to a paddle attachment. Add butter, Splenda, cocoa powder, and vanilla.
  4. Beat on medium speed until fluffy.

Splenda Cream Cheese Frosting

This cream cheese icing is perfect for carrot cake. Using Splenda reduces the sugar by half. The cream cheese frosting will keep in the refrigerator for about ten days; once frosted, keep the cake in the refrigerator until it's time to serve.


  • 1/2 cup granulated Splenda
  • 1 tablespoon plus 2 teaspoons cornstarch
  • 8 ounces reduced fat cream cheese, softened
  • 2 teaspoons vanilla
  • 1/2 cup powdered sugar, sifted

  2. Add all ingredients, including Splenda mixture, to a large bowl.
  3. Beat with an electric mixer until well combined.

How to Use Splenda in Your Own Recipes

Splenda is formulated to be used as a direct, 1:1 substitution for granulated sugar in your favorite recipes, including frostings, glazes, and icings.

Maximum Amount to Use

  • Due to Splenda's different weight and texture, it is recommended that it be used only up to 1 ¼ cups of sucralose in a single recipe; using greater amounts will create difficulties with the final results.
  • If a recipe calls for more than 1 ¼ cups of sugar, you can mix half Splenda and half sugar to still reduce the sugar and calories in the recipe but without as drastic a change in texture. For example, if a recipe calls for one cup of sugar, you can make the same recipe using one cup of Splenda instead. If a recipe requires two cups of sugar, however, it is better to use one cup of sugar and one cup of Splenda for a better texture in such a sweet recipe.

Replacing Powdered Sugar

  • Many icing recipes, however, call for powdered sugar rather than granulated sugar. To substitute Splenda for powdered or confectioner's sugar to create sugar free icing, add cornstarch to the blend and to process the Splenda to create the desired consistency, according to the company's website.
  • For every ¾ of a cup of Splenda, add two tablespoons of cornstarch and blend the mixture in a food processor until it is a fine powder, the same texture as regular powdered sugar. This should take approximately one minute of blending on a high setting. Once processed, the powdered Splenda can be substituted in recipes in the same 1:1 ratio as it is substituted for granulated sugar.
