1 cup nonfat vanilla yogurt
1 cup pumpkin puree (canned pumpkin works great)
1 tablespoons granulated sugar
1 teaspoon pumpkin pie spice

Stir everything together in a large mixing bowl until completely combined (It’s best to stir by hand and not use a mixer). Churn the mixture in an ice cream maker* for a few minutes until it is a smooth, cool consistency.

If you do not have an ice cream maker, you can place the bowl in the freezer and stir mixture every half hour until it reaches desired consistency.

*Churn according to your ice cream maker’s instructions.
