1 1/2 cups all-purpose flour

1 teaspoon baking soda

1/2 teaspoon salt

1/2 cup unsalted butter, melted

1/2 cup packed brown sugar

1/4 cup granulated sugar

1 large egg

1 teaspoon vanilla extract

1 cup chocolate chips

1/2 cup chopped walnuts (optional)

Preheat the oven to 350°F (175°C). Grease a 9-inch pie pan or deep-dish baking dish.
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large bowl, combine the melted butter, brown sugar, and granulated sugar. Stir until well combined.
Add the egg and vanilla extract to the sugar mixture, mixing until smooth.
Gradually add the dry ingredients to the wet ingredients, stirring until fully incorporated.
Fold in the chocolate chips and walnuts (if using).
Pour the dough into the prepared pie dish and spread it evenly.
Bake for 25-30 minutes, or until the edges are golden brown and the center is slightly set. The center will continue to firm up as it cools.
Allow the pie to cool for 10-15 minutes before slicing and serving.

Customize the pie with other mix-ins like white chocolate chips or peanut butter chips for a fun twist.

If you prefer a nut-free version, simply omit the walnuts or use another nut, like pecans or almonds.

To make it gluten-free, substitute the all-purpose flour with a gluten-free flour blend.
