Preheat the oven to 200 degrees and place a baking sheet with a chopped pumpkin for 40 minutes. After the time has passed, purge the pumpkin slices with a blender.
Combine the pumpkin puree with the rest of the ingredients needed to make the syrup, and put the mixture on a small fire for 12-15 minutes. Stir the syrup regularly.
Combine the syrup with the brewed coffee and half of the whole milk. The remainder of the milk is whipped into cream with cream and put a frothy cap over the drink.
