Brew the Coffee: Begin by brewing a strong coffee base using your preferred method, allowing it to cool to room temperature before proceeding.
Prepare the Frappe Mixture: In a blender, mix the cooled coffee with milk, molasses, brown sugar, ground ginger, cinnamon, and vanilla extract, blending briefly to combine without excessive frothing.
Add Ice for Texture: Incorporate ice into the mixture, adjusting the amount to achieve the desired thickness and chill, and blend until smooth.
Serve with Garnish: Pour the frappe into a glass, optionally topping with whipped cream and a sprinkle of cinnamon or ginger for a festive touch.
