Heat the heavy cream in a saucepan over medium-low heat or in the microwave until it is simmering. Make sure it does not boil!
1 ½ cups heavy cream
Pour the hot cream over the chopped chocolate and let sit for 5 minutes.
Stir the chocolate and cream mixture with a rubber spatula until completely smooth, then stir in the salt.
pinch salt
Let sit at room temperature for 2-3 hours until set. If it's too hot when you're making this you can place it in the fridge, but stir it every 15 minutes or so! If you don't whisk, you'll risk lumps in the ganache that will get stuck in the piping bag later.
Once the ganache has set and is firm but still soft, use a handheld electric mixer to whisk until light and fluffy.
Use a piping bag to pipe the whipped ganache frosting on the cupcakes and enjoy!
Notes
My recipes have been developed and tested in metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way. Salt: If you don’t have kosher salt, halve the amount of salt called for in the recipe. 1 teaspoon kosher salt = ½ teaspoon fine salt. Please note I am using Diamond Crystal Kosher Salt, not Morton Salt. Morton salt is too salty for this!Chocolate: Use a chocolate bar for the ganache which has between 50-60% cocoa. Amount: this makes enough frosting to generously frost 12 cupcakes or a 2 layer 8-inch cake. You can double the ingredients to make more frosting!
