- cooking spray
- 2/3 cup white sugar
- 1/2 cup butter, softened
- 2 teaspoons vanilla extract, divided
- 1 pinch salt
- 1 1/2 cups all-purpose flour
- 2/3 cup packed brown sugar
- 1/2 cup light corn syrup
- 3 eggs
- 1/4 teaspoon salt
- 1 cup chopped pecans
- 1/2 cup semisweet chocolate chips, or to taste
- Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13-inch baking dish with cooking spray.
- Beat white sugar, butter, 1 teaspoon vanilla extract, and pinch of salt together in a bowl until smooth; add flour and stir until dough forms. Press dough into the bottom of the prepared baking dish.
- Bake in the preheated oven until edges are lightly brown, 15 to 17 minutes. Cool crust completely.
- Whisk brown sugar, corn syrup, eggs, remaining vanilla extract, and 1/4 teaspoon salt together in a bowl; add pecans and stir to combine. Pour brown sugar mixture over cooled crust.
- Bake in the oven until golden brown and filling is set, 25 to 30 minutes. Cool to room temperature; cut into 36 bars. Place bars in refrigerator until cold, about 1 hour.
- Melt the chocolate chips in a microwave-safe glass or ceramic bowl in 30-second intervals, stirring after each melting, for 1 to 3 minutes (depending on your microwave). Set cold bars on waxed paper and drizzle melted chocolate over the top.
