Special equipment: six heat-safe 5-ounce coffee mugs or oven-safe ramekins
Preheat the oven to 325 degrees F.
Combine the coconut milk, cream and coconut extract in a small saucepan over medium-high heat and bring to a boil. Once at a boil, remove from the heat.
Meanwhile, whisk together the eggs and 5 tablespoons sugar in a bowl until combined.
Slowly whisk the heated cream mixture into the eggs, stirring constantly.
Divide the mixture among six heat-safe 5-ounce coffee mugs or oven-safe ramekins, filling them about 3/4 of the way up. Put them in a baking dish and add enough warm water to the baking dish so that it comes halfway up the sides of the coffee mugs.
Bake until the center is nearly set. Baking time will depend on the height of your coffee mug or ramekin. Bake time is 10 minutes for every 1/2 inch of height. For a 1-inch vessel, bake the creme brulees about 20 minutes. For a 2-inch vessel, bake the creme brulees about 40 minutes. Remove from the oven and allow to completely cool in the water bath, then refrigerate 15 to 20 minutes before serving.
Before serving, sprinkle the tops with a heavy layer of sugar and brulee using a hand torch or heating under the broiler for 2 to 3 minutes.
