This has been my fave dish lately – I’ve already made it four times this month!

1 unbaked 9-inch pie crust
1 cup granulated sugar
1 cup brown sugar, packed
1 cup (2 sticks) unsalted butter, softened
2 large eggs
1 teaspoon vanilla extract
½ cup all-purpose flour
½ teaspoon baking powder
¼ teaspoon salt
1 ½ cups semi-sweet chocolate chips
1 cup chopped nuts (optional, such as walnuts or pecans)
