In a stand mixer fitted with the paddle attachment, or in a large bowl with a hand held mixer, combine the room temperature butter with the confectioners' sugar on low speed. Once combined, increase the speed to medium-high and beat until light and fluffy
Increase the speed to medium-high and beat for 2-3 minutes, until light and fluffy.
If the frosting isn't as creamy as you would like, add in the heavy cream and beat on medium speed until spreadable. You might not need all of it!
¼ cup heavy cream
Notes
My recipes have been developed and tested in cups and metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way.I make sure that all of my ingredients are at room temperature before I start the recipe, so pull out all of the ingredients before you start baking.Butter: I use European style butter in my recipes. This will make your frosting much creamier and richer.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 and not Morton Salt, which is far too salty for this recipe. Amount of Frosting: This recipe makes enough to generously frost 14 cupcakes or thinly frost a two layer 8-inch cake. For a larger cake, I recommend doubling the ingredients.Freeze-Dried Raspberries: you want to use freeze-dried raspberries and not frozen or dried raspberries! Storage: Keep in an airtight container in the fridge for up to 5 days. Let it come to room temperature before eating.
