Add instant espresso powder to a glass and stir in warm water until fully dissolved.
Mix in the pumpkin sauce or syrup.
Fill the glass with ice, pour in the milk, and stir.
Top with whipped cream if you want to go extra cozy, then sip away.
Notes
Can this be made with classic espresso instead of instant espresso? Yes. Use a double shot of espresso in place of the instant espresso powder and water.How can I deepen the spiced flavors in the drink? Add 1/8 to 1/4 teaspoon of pumpkin pie spice or cinnamon, adjusting to taste. This creates a stronger spiced flavor, similar to an Iced Pumpkin Spice Latte.Can I make this hot? Yes. Omit the ice and warm the milk on the stove. Do not boil the milk—just heat until warm before mixing.Can this be made with cold brew? Yes. Substitute the espresso powder and warm water with 4 tablespoons of cold brew.
