With only 6 ingredients, you can make this smooth and creamy coffee creme brulee with caramelized sugar topping, the perfect dessert for coffee lovers!
In a saucepan, combine the heavy cream, vanilla bean, and instant coffee. Bring to a simmer over medium heat. Then remove the pot from the heat and let it cool for about 5-10 minutes (This will allow the vanilla to steep and extract flavor and also bring down the temperature a bit.)
In a medium mixing bowl, add the egg yolks, granulated sugar, and salt, and whisk until smooth. Then, slowly add the coffee cream mixture into the eggs, one ladle at a time while whisking constantly. Continue to do this until all of the coffee cream has been added.
Pour the coffee custard mixture equally into 4 ramekins, passing through a small strainer to get out any impurities (i.e. pieces of egg, film on cream, coffee particles). Place the ramekins into a glass baking dish and skim the bubbles off the top of each custard. Then, carefully add hot water to the baking dish, careful not to get any water in the ramekins. The water should come at least halfway up the sides of the ramekins.
Carefully place the baking dish in the oven and bake for about 40-45 minutes (or to an internal temperature of approximately 176 °F). Remove the ramekins from the water bath, let the custards cool to room temp, then wrap them in plastic wrap and refrigerate for at least 4 hours or overnight.
Place an even layer of superfine or granulated sugar on top of each chilled custard (about 2 teaspoons each, or enough to fully cover the top in a thin layer). Using a kitchen torch, run the flame over the sugar in sweeping motions until the sugar begins to turn golden brown.* Let sit for about 2 minutes before serving to allow to sugars to cool and create the crackly hard shell on top. Then serve!
Notes
If using whole coffee beans, allow the beans to steep longer (about 30 minutes) to fully extract the coffee flavor.

You can use the same recipe to make vanilla creme brulee, simply leave out the coffee. The method and other ingredients are all exactly the same.
