I've made recipes from this great little cookbook before, but I think it deserves a revisiting. The original chocolate chip cookie recipe this is based off of is from Little Old Lady Recipes. It really is such a charming little book. Tried and true recipes from grandmothers are included alongside delightful portraits photos of grandmas. I made some adaptations and have included these below.
Side by Side Chocolate Chip Cookies, adapted from Little Old Lady Recipes
1 cup + 2 Tablespoons all purpose flour
3 Tablespoons Cocoa Powder
1/2 tsp baking soda
1/2 tsp fine sea salt
1/2 cup unsalted butter, room temp
1/3 cup granulated sugar
1/2 cup light brown sugar
1 large egg, room temp
3/4 tsp vanilla extract
3/4 cup chocolate chips
Preheat the oven to 325, and line two cookie sheets with parchment paper.
In the bowl of an electric mixer, cream together the butter and sugars. Add the egg and vanilla. Then, add baking soda, and salt. Add 1 cup of the flour and mix until just incorporated. Remove half of the dough from the bowl, and set aside. In the electric mixer, add the remaining 2 tablespoons flour and half of the chocolate chips. Mix until just incorporated, then drop by the tablespoon onto the prepared cookie sheets. Now, add the reserved half of the dough back into the stand mixer bowl. Add the cocoa powder and the remaining chocolate chips. Drop by the tablespoon onto the cookie sheet so that each standard chocolate chip cookie dough ball has a double chocolate chip cookie dough ball beside it. With your finger, make the two dough balls touch. Bake for 8 - 12 minutes or until cookies begin to brown at the edges. Remove to rack to cool.
