Add chai tea concentrate to an ice-filled glass. Pour milk into the glass.

Top drink with pumpkin cream cold foam and sprinkle pumpkin pie spice over the top.

Mix milk, cream, vanilla syrup, and pumpkin spice sauce in a mason jar and shake to combine. Alternatively, stir all ingredients together in a bowl.

If not using right away, store in an airtight container in the fridge.

Turn the mixture into cold foam right before using by frothing with an electric frother, hand mixer, or blender until foamy.

In a medium saucepan over medium-low heat, combine condensed milk, pumpkin puree, pumpkin pie spice, and salt. Stir together and heat for about 5 minutes, until bubbling.

Remove from heat and stir in vanilla extract. Pour the mixture into a heat-proof jar or bowl and refrigerate to cool.
