- cooking spray
- 1 (9 inch) prepared pie dough, thawed if frozen
- 1/4 cup butter at room temperature
- 1 cup brown sugar
- 2 eggs
- 1 (15 ounce) can pumpkin puree
- 1 1/4 cups all-purpose flour
- 1 tablespoon pumpkin pie spice
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 (11 ounce) package butterscotch chips
- 1/2 (2.25 ounce) package chopped pecans (optional)
- 2 tablespoons confectioners' sugar, or to taste (optional)
- Preheat oven to 375 degrees F (190 degrees C). Prepare a 9×13-inch pan with cooking spray.
- Mold the pie crust to fit the pan. It may be thin in some spots; that's ok, just try to get it as even as possible.
- Beat butter and brown sugar together with an electric mixer in a large bowl until smooth. Beat 1 egg into the butter until completely blended; repeat with the second egg.
- Mix flour, pumpkin pie spice, baking soda, and salt together in a separate bowl. Add to pumpkin mixture and beat to combine. Fold butterscotch chips and pecans into the mixture; pour into the pie crust.
- Bake in preheated oven until a knife inserted in the center comes out clean, 25 to 35 minutes. Dust with confectioners' sugar.
