Make the coffee first. You may wish to make a full cup of coffee, allow it to cool, then remove the amount needed for the recipe. Turn on an oven and preheat it to 350 degrees. For each serving of custard, choose an oven-safe, 4-ounce ramekin, and spray it lightly with pan spray. Make the custard simply by whisking together all the ingredients listed (the coffee cannot be hot).
Step 2
Pour the batter into the ramekin, allowing any air bubbles to naturally rise to the top without tapping the dish. Set the ramekin inside another heat-safe, shallow dish, such as a cake pan or glass baking dish. Use an electric kettle or stovetop to bring some water to a boil. Once the water just reaches a boil, pour the water into the base of the larger dish until it rises to 1-inch high against the ramekin.
Step 3
Place the dish of water with the ramekin in your oven. Bake the custard for 30 minutes until done. You can pour additional water into your larger dish if the water level becomes too low while the custard is baking. To check for doneness, the custard will naturally pull away from the edges of the ramekin, it will have a slight wiggle to it (no liquid), and will have a clean toothpick test. Enjoy the custard warm or chilled.
