- Preheat the oven to 350°F (176C) and line a cookie sheet with parchment paper 
- In a medium bowl mix the dry ingredients together. I use a whisk so they blend well until the mixture looks fluffier. 
- In a mixing bowl beat the butter and the sugar until light and fluffy. Medium high setting for approximately four minutes. Add the applesauce and vanilla and mix for two minutes. 
- Slowly add the flour to the butter mixture. I like to add ⅓ of the mix, blend, then another third, and so on. 
- When the flour is completely blended into the butter mixture stir the chocolate chips in by hand. Use a one quarter measuring cup to measure out each cookie. Roll the dough in a ball and flatten into a thin disc. You should be able to make twelve cookies for six sandwiches. 
- Bake for 14 to 15 minutes or until they begin to brown. Remove the pan from the oven and let the cookies rest for 2 minutes then transfer with a spatula to a cooling rack. 
- While the cookies are baking let the ice cream thaw slightly then cut six one inch disks with a serrated knife and peel off the paper container. Stack them with a square of parchment paper in-between and put them back in the freezer until you’re ready to assemble the sandwiches. 
- To assemble put one cookie bottom side up on a smooth surface then add the ice cream disk and top with a cookie bottom side down. 
- You can form individual cookies with the dough and layer with parchment paper in a freeze tight container and freeze until you’re ready to bake. 
- Baked cookies will keep in an air tight container in the freezer for one month.
