In a small saucepan, bring the water to a boil. Add the rolled oats and reduce the heat to medium-low. Cook for about 5 minutes, stirring occasionally, until the oats have absorbed most of the water and become creamy.
While the oats are cooking, brew a ½ cup of strong coffee using your preferred brewing method.
Once the oats are cooked, pour in the brewed coffee, milk, maple syrup (or sweetener), vanilla extract, and a pinch of salt. Stir well to combine.
Continue cooking the oatmeal for another 2-3 minutes, stirring occasionally, until it reaches your desired consistency. If it becomes too thick, you can add more milk to thin it out.
Remove the oatmeal from the heat and let it sit for a minute or two to cool slightly.
Serve the coffee oatmeal in bowls and garnish with your favorite toppings, such as sliced almonds, shredded coconut, chocolate chips, or fresh berries.
