Vegan Friendly Chocolate Mousse Frosting

Being that the frosting has a cooking stage it may seem to be more complicated, but fear not, it isn’t! And better – it has a lot less sugar than most frosting as well. More so it can be made with a soft tub spread and not stick spread, leaving it a bit better both fat wise and calories. If you are not concerned with it being vegan I would suggest a brand like Brummel and Brown, which has a nice tart flavor.

For this past Christmas Kirk bought me one of these for my Kitchenaid mixer, it has been great for batters and frosting: New Metro Design Beater Blade for 5-Quart KitchenAid Bowl Lift Mixers, White.

Spread on my recent Chocolate Cupcakes:

Chocolate Mousse Frosting


  • 1 Tbsp cornstarch
  • ½ cup light vanilla soy milk (used Silk brand)
  • ½ cup granulated sugar
  • ¼ cup unsweetened cocoa powder
  • ½ cup tub spread (preferably a heart healthy version/reduced fat)
  • 1 tsp pure vanilla extract
  • 2 Tbsp powdered sugar (see notes below)


  1. In a small saucepan whisk the cornstarch and milk together till smooth. Bring to a boil over medium heat, stirring constantly. Once boiling it will thicken quickly, take off the heat and scrape into a small bowl to cool.
  2. Sift the cocoa powder 2 to 3 times to remove any lumps.
  3. In a stand mixer add the sugar, cocoa and spread. Beat on low until combined, turn up to high and let beat for 5 minutes. Turn to low and add in the vanilla, then add in the thickened (cooled) mixture and let beat in till smooth, then turn back up to high and beat for 3 minutes more.
  4. Add in the powdered sugar and beat till mixed in.
  5. Let chill for an hour in the refrigerator and then spread on cupcakes or a single layer cake. Store the frosted items in the refrigerator covered without it touching the frosting.


Want to make homemade powdered sugar? Easy enough!

In a glass blender add 1 cup granulated sugar + 1 heaping Tablespoon cornstarch and process on high until the sugar is ground down finely – depending on your blender it will take a minute or two.
