Step 1

Preheat oven to 350°F; line two baking sheets with parchment paper or use a silpat.

Step 2

In a medium bowl, whisk together flour, baking powder, baking soda, salt and cinnamon.

Step 3

In a large bowl, with a mixer, cream together the butter and the sugars on medium speed.

Step 4

Add the egg, followed by the applesauce and vanilla extract.

Step 5

Working by hand, stir in the flour mixture and the oats until just combined and no streaks of flour remain; stir in the chocolate chips.

Step 6

Drop heaping tablespoonfuls (approx 1 tbsp each) of the dough onto prepared baking sheets, flattening each cookie slightly (I forgot to do this).

Step 7

Bake for about 10-12 minutes, or until cookies become light brown at the edges.

Step 8

Let cool on baking sheet for 3 or 4 minutes, then transfer to a wire rack to cool completely.

Step 9

Store in an airtight container so you don't eat them all in one sitting!
