A More Heat Resistant Frosting?

Because of the shortening in the recipe, this fluffy chocolate frosting is a bit more heat resistant than butter-based frostings. This is always going to be the case with frostings that contain shortening. This is especially helpful for summertime gatherings!

Some frostings contain no butter at all, and rely entirely on shortening. People have mixed feelings about this. Those who live in very hot or humid climates find it to be a necessity, although losing the butter means that you have to rely more on extracts for making up for the flavor lost from omitting the butter.

For me, I usually use an all-butter frosting or a recipe like this one that contains at least some butter.  


There is no such thing as Buttercream that will not melt

Please don't mistake heat resistant for heat-proof! ;0) Sadly, there is no such thing as a frosting that will not melt.

If you leave a frosted cake out in the heat or directly in the sun for an extended time, bad things are going to happen. If you have an outdoor event on a hot day, keep the cake cool until close to the time of serving.

However, it's nice to have an option that can withstand warmer temperatures a bit better. Plus, it is SO simple to make.

Enjoy the recipe!

A delicious, fluffy chocolate frosting, perfect for piping. The shortening in the recipe makes it a bit more heat resistant than an all-butter recipe.


  • 1 stick (113g) unsalted butter, softened
  • 1 ½ cups ( 285 grams) vegetable shortening
  • 7 cups (793 g) powdered sugar
  • 1 ¼ c. (86 grams) cocoa powder, loosely fill your measuring cup
  • ½ c. (114g) water or milk
  • 2 teaspoons vanilla


  1. Cream butter and shortening until creamy.
  2. Blend in the vanilla. Add powdered sugar, cocoa and most of the water. Mix throughly on medium speed for approximately 6 - 8 minutes until creamy and smooth.
  3. Add your remaining milk (or water) as necessary. Scrape the sides of the bowl occasionally during the mixing process.
  4. Recipe can be doubled
  5. This is a crusting buttercream, it pipes great, and works well with the viva paper towel method of smoothing (if you're going for that super smooth finish).

  1. Does this frosting has to be refrigerated? Does the cake has to be refrigerated after filling/crusted with this filling? Thanks

  2. Hi Claudia, I think it is fine to be out 3 days. I would keep it out of direct sunlight and in a cool area.

  3. This recipe is wonderful! I was using Wilton's chocolate recipe - and this is far superior in taste and the way it frosts! My go-to chocolate frosting recipe from now on!

  4. Just made this tonight - this frosting is the perfect amount of sweetness. I followed the advice above to decrease the milk to 1/4 cup plus 2-3 tbs, but this wasn't enough liquid. The frosting wasn't as smooth and a little too crusty, so next time I would use the full 1/2 cup of milk. I traditionally use hi-ratio shortening, butter, and white margarine in my frosting, but I love that this recipe leaves out margarine. Thumbs up from my daughter and husband as well. Thanks for the recipe!

  5. If I use this as a filling will it still crust? I won't need a crusting BC for the filling, but I don't want it too soft either because I want the filling to be a little on the thick side since I won't be icing the cake, just a think layer of ganache under fondant. What do you recommend as a chocolate filling that's a light chocolate taste?

  6. Used as a filling I don't think it will crust as it won't be in contact with the air. This recipe as well as our Classic Chocolate Frosting recipe has a light chocolate taste.
