Preheat the oven to 350℉/180℃ and line two trays with parchment paper. Melt and cool the butter.
In a medium bowl, add in flour, oats, cinnamon, baking powder, baking soda, and salt.
2 cups all-purpose flour, 1 cup rolled oats, 3/4 tsps baking soda, 1 tsp cinnamon, 3/4 tsps baking powder, 1/2 tsp salt
In a large bowl, whisk butter, brown sugar, and sugar. Add in vanilla, egg, and applesauce. Whisk until smooth.
1/2 cup butter, 1/3 cup brown sugar, 1/2 cup white sugar, 1 egg, 1 tbsp vanilla, 3/4 cups unsweetened applesauce
Add in the dry ingredients and mix until a soft cookie dough forms. Don't over-mix!
Add in the chocolate chips and mix in.
3/4 cups semi-sweet chocolate chips
Scoop 6 cookie dough balls and place on the prepared cookie sheet.
Bake for 13-16 minutes. Mine took 16 minutes. The cookies will be ready when the edges are a golden brown, but the inside will look very soft. Remove from oven, let the cookies cool on the hot pan for a few minutes before serving warm or cool completely and enjoy!
