If using pumpkin puree, you may wish to use the 4 Tbs. of maple syrup in the filling. Sweet potato puree is sweeter, and you could reduce it to 3 Tbs. If you prefer a very lightly sweetened filling, you could use even less sweetener and it is still delicious.
Coconut butter tends to harden if you have a cooler home or pantry. To liquify the coconut butter, place the jar in a saucepan of hot water, with water coming halfway up the jar. Once softened, stir to create a creamy consistency.
