1-Preheat your oven: preheat your oven to 350°F and lightly spray a 9-inch pie plate with non-stick baking spray.

2-Mix the wet ingredients: In a large bowl, beat the melted butter, light brown sugar, and granulated sugar until they’re well combined. This creates a smooth base for the flavors to shine. Next, add the large egg, 2 egg yolks, and vanilla extract; mix everything until it’s thoroughly incorporated for that rich taste.

3-Combine the dry ingredients and add mix-ins: Stir in the all-purpose flour, cornstarch, and salt until just combined don’t overmix to keep the texture light and chewy. Gently fold in the semi-sweet chocolate chips and toffee bits to distribute them evenly.

4-Bake the cookies: Spread the batter into your prepared pie plate, making sure it’s level for even baking. Bake for 35 to 40 minutes until the top is golden brown, the edges are set, and the center has a slight jiggle.

5-Cool and garnish: After baking, cool the pie on a wire rack for at least one hour before slicing to get those perfect wedges. For an extra touch, sprinkle on more toffee bits and chocolate chips right after pulling it from the oven.
