In a mixing bowl, combine the instant coffee, dark brown sugar, and boiling water. Stir until everything is dissolved.
Using an electric mixer, beat the coffee mixture on high speed for about 2-4 minutes, or until it becomes light and fluffy.
Gently fold in the vanilla extract to enhance the flavor.
In a glass, add ice and pour the milk of choice over it, leaving some space at the top for the whipped coffee.
Drizzle maple syrup into the milk, adjusting the amount to your sweetness preference. Stir gently to combine.
Spoon the whipped coffee mixture over the milk and ice. Use a spatula to create a beautiful layer on top.
Before sipping, give your drink a gentle stir to mix the whipped coffee and milk. Enjoy!
