Prep: Cream the softened butter and packed brown sugar in a mixing bowl until they are well combined and fluffy, about 2-3 minutes.
Mix Wet Ingredients: Add the large egg, egg yolk, and vanilla extract to the butter mixture. Blend until everything is thoroughly combined.
Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt.
Combine: Gradually add the dry ingredients to the wet mixture, stirring gently until just incorporated.
Fold-in: Carefully fold in the mini semi-sweet chocolate chips.
Assemble: Spray a 9-inch pie plate with non-stick spray. Transfer the dough into the plate, pressing it evenly across the bottom and up the sides.
Bake: Place in a preheated oven at 350 degrees F and bake for 30-35 minutes.
Reshape: Once out of the oven, while the crust is still warm, gently press the bottom with a glass to reshape.
Cool: Allow the crust to cool completely on a wire rack.
Fill: Once cooled, fill it with your desired no-bake pie filling.
