First of all, take the saucepan and put it on the medium heat stove. Add water and sugar in the saucepan and mix boil them together. Keep mixing the sugar until it is fully dissolved. Then, add ginger and cinnamon in the pan and keep whisking consistently. You will have to cook them for around 15 minutes or until the syrup becomes a little bit thickened. It is extremely important for you to keep stirring the mixture.
Now add the vanilla extract and allow the mixture to cool down by removing it from the stove. When it becomes cooler, store the syrup in a bottle or Tupperware. You will have to shake it well before using it.
Now, to make the gingerbread latte, pour the milk in the coffee mug and add the syrup in it. Place the mug in the microwave for around one minute. Then, add the brewed coffee in the mug. Before adding the coffee, make sure that the milk and syrup are hot otherwise you will not be able to get the desired taste of your gingerbread latte. Furthermore, it will be better for you to use 8 oz coffee. However, you can also use any other coffee if you want.
In the end, use the whipped cream as topping and sprinkle some ground cinnamon on your coffee. Serve along with biscuits or any other snacks and enjoy the Starbucks gingerbread latte.
