1. Prepare the Homemade Pumpkin Spice Sauce: In a small saucepan, combine the pumpkin puree, granulated sugar, water, and pumpkin pie spice. Place the saucepan over medium heat. Stir constantly until the sugar dissolves and the mixture begins to simmer gently. Reduce the heat to low and continue to simmer for about 5-7 minutes, stirring occasionally, until the sauce thickens slightly. It should coat the back of a spoon. Remove from heat and stir in the vanilla extract. Let the sauce cool completely. For best results, you can transfer it to a jar and chill it in the refrigerator for at least 15 minutes. The sauce will thicken more as it cools.

2. Brew and Chill Your Coffee: If you haven’t already, brew a strong batch of your favorite coffee. Allow it to cool down to room temperature, then chill it in the refrigerator until it’s cold. This is crucial for an iced latte so your ice doesn’t melt too quickly and dilute the flavor.

3. Assemble the Latte Glass: Grab a tall glass and fill it about two-thirds of the way with ice cubes. The more ice, the colder your latte will be.

4. Add the Pumpkin Spice Sauce: Spoon 2 tablespoons of your homemade pumpkin spice sauce directly over the ice in the glass. You can adjust this amount based on your preference for sweetness and spice; add a little more for a bolder flavor, or a little less if you prefer it milder.

5. Pour in the Milk: Carefully pour 1 cup of your chosen milk into the glass, over the ice and sauce.

6. Add the Chilled Coffee: Gently pour 1 cup of the chilled strong brewed coffee into the glass.

7. Stir and Serve: Using a long spoon or a stirrer, mix all the ingredients thoroughly until the pumpkin spice sauce is fully incorporated and the latte has a uniform color. Taste and adjust if needed. If desired, top with a dollop of whipped cream and a sprinkle of ground cinnamon or pumpkin pie spice for an extra touch of indulgence. Serve immediately and enjoy!
