To make a homemade gingerbread latte, whisk everything except the coffee and vanilla extract in a small saucepan over low heat, just until hot. Alternatively, microwave for about forty seconds. If you have a cooking thermometer, it should reach 150 degrees Fahrenheit. Remove from the heat, add the vanilla, and use a milk frother or whisk for a few seconds. The steamed milk should form small bubbles. Pour this mixture over the coffee or espresso in a mug. Enjoy hot or cold over ice.View Nutrition Facts
