Ingredients

Quick Chocolate Frosting

  • 340 g powdered sugar icing sugar
  • 60 g Dutch processed cocoa powder sifted (see notes)
  • 1/2 tsp fine salt
  • 120 g unsalted butter softened (see notes)
  • 80 g hot milk
  • 1 tsp vanilla extract

Instructions
 

Quick Chocolate Frosting

  • Combine dry ingredients - Run the powdered sugar, cocoa powder and salt through a sieve into a large mixing bowl. Use a whisk to combine.
  • Mix in butter - Add the softened butter and use an electric hand mixer to beat on medium speed until it’s broken up a little and looks crumbly. About 2 minutes.
  • To finish the frosting - Add the hot milk and vanilla extract. I warmed mine up in the microwave until it was warmer than warm. Almost hot. Do this right before you add it so it doesn’t form a skin. Then mix until combined and it becomes a spreadable consistency.

Notes

Dutch processed cocoa powder - is an unsweetened cocoa powder which has been treated with alkaline and potassium carbonate to neutralize the acidity that is naturally found in cocoa powder. It’s darker in color and strong in chocolate flavor.
Softened butter - Your softened butter should be firm enough that it holds its shape but yield gentle pressure when pressed with your finger. You can soften your butter using one of two ways. Room temperature method: you can do this by taking your butter out of the fridge and cutting into cubes. Let it sit at room temperature for 1 hour before using. Microwave method (quicker): cut into cubes and place in a heatproof bowl or plate. Microwave for 10 seconds at a time until it’s soft but firm enough to hold its shape with some resistance.
Storage - This frosting can be stored in an airtight container, in the fridge for up to three days.
