I never have pie spice at the beginning of the baking season. I had every other ingredient for the Crustless Pumpkin Pie (which is amazing and you have to try it!), but no pie spice.
I found a recipe for the spice on food.com and here it is…
This spice is a blend of warm spices. Typically ingredients are: cinnamon, nutmeg, cloves, allspice and mace. Pumpkin pie spice adds a nice extra pumpkin taste to pumpkin pie.
Season: available year-round
Substitutions: 1/2 tsp ground cinnamon + 1/4 tsp ground ginger + 1/8 tsp ground allspice + 1/8 tsp ground nutmeg = 1 tsp pumpkin pie spice
