Chocolate cookies in a Jar

I made 3 different kinds of "cookie in a jar" recipes for my husbands co-workers for Christmas. The next day my children and I decided to try out one of the recipes and chose the Chocolate cookies (found on allrecipes.com). These have really great chocolate flavor and the first day they are crunchy on the outside and soft on the inside. But by the next day they were hard all the way through. They still had great flavor, but I think if I make them again I will under bake them a bit (I baked them for 12 min-may go for 9 or 10 min in the future). I followed the recipe with the exception of using 1/2 semi-sweet chocolate chips and 1/2 white chocolate chips. These have some of the best chocolate flavor I have made in a cookie-so for that reason I give them 4.5 out of 5 stars since they do harden too quickly. I wish I had taken a picture of these because my jars were adorable and they layered perfectly!

1 3/4 cups all-purpose flour

Directions
Combine all-purpose flour, baking powder, baking soda, and salt. Set aside.
In a 1 quart wide mouth canning jar, layer dark brown sugar, white sugar, cocoa, chopped pecans, and chocolate chips. Pack everything down firmly before you add flour mixture, it will be a snug fit.
