If you enjoyed my cookies (if you had any :P) this is the recipe I use for chocolate chip. You can scale it up if needed. For PAX what I usually do is double everything but the chocolate chips. I'll use one bag of mini chocolate chips instead of two since I find that they tend to spread through the dough very well and give lots of chocolately flavor. This is a slight variant of the Toll House recipe.
Mix together in a bowl and set aside: 2.5 Cups of AP Flour, 1 tsp baking soda, 0.5 tsp salt
In a stand mixer (or bowl that you will be mixing in) beat together: 1 stick of margarine, 1 stick of butter, 1.5 cups of granulated sugar, 3/4 tbls of molasses (you could probably get away with 1tbls), 1 tsp vanilla. Scrape down the bowl to ensure its creamed together well.
Beat in two eggs, one at a time, scraping down the bowl after each addition.
Stir in the flour mixture gradually, scraping down the bowl.
Stir in the chocolate chips.
Preheat oven to 375 degrees F and drop teaspoons of the dough onto cookie sheets and bake for about 10 minutes or until golden brown. Remove from cookie sheets and allow to cool.
I froze the dough and baked them on parchment paper, which worked amazingly (love parchment!).
If you find that your cookie is too dry/tough you can decrease the flour down to 2 and 1/4 cups of flour if needed.
Chocolate chip cookies! Simple but effective!
