Preheat oven to 375°F. Line a baking sheet with a precut Reynolds Cookie Baking Sheet. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, cream the butter with the sugar until smooth and fluffy.
½ cup unsalted butter, 1 cup granulated sugar
Pour in the applesauce and continue to beat until fully mixed.
1 cup cinnamon applesauce
Add in the baking soda, salt, vanilla extract, and 1 cup of the flour. Place the mixer on a lower setting and beat until combined. Add in the remaining cup of flour and beat until just mixed. You don't want to overmix the dough.
2 cups all-purpose flour, 1 teaspoon baking soda, ½ teaspoon kosher salt, 1 teaspoon pure vanilla extract
Use a spoon or spatula to fold in the chocolate chips.
1 cup milk chocolate chips, ½ cup semisweet chocolate chips
Use a cookie scoop to drop the cookies onto the baking sheet, about 1-2 inches apart.
Bake for 12-15 minutes, or until the cookies are just golden brown and baked through.
Repeat with the remaining dough.
Let the cookies cool on a wire rack to room temperature.
