Step 1

If using the coffee powder, add it to a small cup with the tablespoon of hot water and stir until dissolved.

Step 2

Combine the condensed milk, chocolate, vanilla, dissolved coffee, and salt in a glass bowl or 4-cup measure. Microwave for 45 seconds and stir for up to a minute to completely melt the chocolate (alternately, cook over a double boiler or low flame, stirring constantly, until chocolate is melted).

Step 3

Set aside to cool while whipping the cream.

Step 4

Whip the cream with a mixer until stiff peaks form. Add a portion of the whipped cream to the chocolate mixture and fold in. Then pour all the chocolate into the remaining whipped cream, folding with a spatula until mixed with very few white streaks left.

Step 5

Pour into a freezable container, cover, and freeze for at least 8 hours - overnight is better.
