Whisk water, apple juice and brown sugar together in a microwave-safe bowl. Microwave mixture for about two minutes until it starts to boil.
Take the simple syrup mixture out and add spices. Whisk together.
Put back in the microwave and watch until it boils again. Should take under one minute.
Remove and let rest until cool. Store in an airtight container in the refrigerator.
Spiced apple drizzle
Stir the apple brown sugar syrup and caramel sauce together in a small container until mixed.
Make the macchiato
Add the apple brown sugar syrup to the bottom of your cup.
Heat oat milk, or milk of your choice. If using the microwave heat to 150° F or very warm to the touch, about one minute.
Froth milk using a frothing tool or French press. Add milk on top of the syrup. Make sure there is at least a half inch of foam at the top. Leave enough room for the espresso shots to be added on top.
Gently pour the two ounces of espresso or double-strength coffee on top of the milk.
Add spiced apple drizzle on top.
Optional: Finish with a bit of cinnamon or apple pie spice sprinkled on top!
