Whisk together sugar and unsweetened cocoa powder in a medium pot - no heat.

Slowly mix in heavy cream and turn heat to medium-low, continue to mix. Once nice and hot, add butter (in chunks). Stir until smooth.

Once it's super warm, remove from heat and add 1 tablespoon of vanilla and dash of salt

Let cool 5 minutes in pan; use and store remaining in jar in the fridge!

Too warm up: take desired amount and warm for about 15-20 seconds
