Continuously stir the mixture over medium-high heat for about 15-20 minutes to allow the mixture to thicken and the flavors to meld together. The pumpkin goes from bright orange to brownish-orange. Taste and adjust seasonings as desired, adding more spice or sweetness.
Remove the pumpkin butter from the heat, allow it to cool, then transfer it to a jar or serving dish.
Notes
Adjust the sweetness to taste. You can add more brown sugar, maple syrup, or honey to get the sweetness to your liking. You can omit the brown sugar and just use maple syrup if desired.You can also adjust the spices to your liking. Feel free to add a little ground ginger (1/4 tsp) or even apple cider to deepen the flavors. Be sure to cook off excess liquid so you're left with a thick, spreadable dip.Store the pumpkin butter in a sealed jar in your fridge for up to two weeks.
