Place small saucepan on medium-low heat. Whisk together 2 1/2 cups milk and pumpkin puree.
Add tea bags and simmer for 5 mins on low heat.
Remove tea bags and whisk in 2 tbsp maple syrup and pumpkin spice. Set aside.
In a microwave safe mason jar, add remaining milk, cover with lid and shake rigorously for 60 seconds. You should notice froth on top of the milk.
Remove lid and place jar in the microwave for 30 seconds. This will stabilize the froth.
Pour pumpkin mixture into your favourite cup. Top with milk froth from mason jar and garnish with cinnamon.
