1 1/2cupsunsalted butter - slightly cooler than room temperature
1teaspoonvanilla extract - you can leave this out but I love the vanilla undertone it gives
1/4teaspoonsalt
4cupspowdered sugar
2tablespoonscocoa powder
6tablespoonswhipping cream
1teaspooninstant espresso or pero
Instructions
Add egg yokes to a mixing bowl with a whisk attachment.
Heat sugar and water in a sauce pan with a candy thermometer attached to the side. Candy thermometers can be off so I always do the ice water test too, see instructions below.
Don't stir the mixture but allow to the mixture to come to a boil then stir.
Once mixture hits 238 F. or just below the soft ball stage remove from heat and turn on your mixer with a whisk attachment and pour the sugar into the side of the bowl with the egg yokes while it is mixing.
Whisk until smooth and cooled down to room temperature.
Add butter to mixture and blend until smooth.
Add vanilla, salt, powdered sugar, cream, cocoa powder, and instant espresso powder or pero and blend until mixture is soft and fluffy.
