ArcaMax

1/2 cup packed (3 1/2 ounces) dark brown sugar

1/4 cup (1 3/4 ounces) sugar

1 large egg

1 teaspoon vanilla extract

1/2 cup (3 ounces) chocolate chips

1. Adjust the oven rack to the upper-middle position and heat the oven to 375 degrees. Spray the inside bottom and sides of a 9-inch springform pan with vegetable oil spray.

2. In a medium bowl, whisk together flour, baking soda and salt. In a large bowl, whisk melted butter, brown sugar and sugar until well combined. Add egg and vanilla and whisk until smooth.

3. Add flour mixture to butter mixture and use a rubber spatula to stir until just combined and no dry flour is visible, about 1 minute. Add chocolate chips and stir until evenly distributed.

4. Use a rubber spatula to scrape cookie dough into a greased springform pan and spread the dough into an even layer covering bottom of pan. Bake until the cookie is golden brown, and the edges are set, 18 to 22 minutes.

5. Transfer the springform pan to a cooling rack and let the cookie cool in the pan for 30 minutes. Run a butter knife around the inside edge of the springform pan to loosen the edges of the cookie from the pan. Unlock and remove the side of the pan. Use an icing spatula or a wide metal spatula to loosen the bottom of the cookie from the pan and transfer the cookie to a cutting board. Cut the cookie into wedges and serve warm.
