When Chocolate Chip Cookies are needed STAT!

The boys group Andy leads is doing their baking badge and the needed an easy cookie recipe that didn't require a whole lot of equipment. Last week they made cupcakes, next week cookies. The last time I let the boys use my mixer they started peeling my decals off of it... yes, my mixer is pimped out - are you surprised? you shouldn't be... it's been like that for almost 20 years. Anyway... something easier, but something quick. I found a no chill brown butter recipe which I converted into just a melted butter, modified ingredient amounts, then of course we needed a test. So, Friday after work I whipped up a batch of these cookies, they were gone by Sunday. So, you could say they were enjoyed, quickly.
So, if you need a quick batch of yummy soft cookies that get put together really quickly and even 5th and 6th grade boys can do it? These are great.

No Chill Chocolate Chip Cookie Recipe
1/4 cup unsalted butter
1/4 cup packed dark brown sugar
2 Tbsp granulated sugar
1/2 teaspoon pure vanilla extract
1 large cold egg
1/4 teaspoon baking soda
1/4 teaspoon salt
2/3 cup all-purpose flour
1/2 cup chocolate chips

Melt butter in microwave Add brown sugar, white sugar, and vanilla and whisk to blend. Add whole egg and whisk until incorporated. Then whisk in baking soda and salt.
Add the flour and fold it in until mostly combined, then fold in chocolate chunks.
Preheat your oven to 350°F. Line two large cookie sheets with parchment paper.
Use two spoons to scoop 14 pieces and roll into smooth balls. Place them onto prepared baking sheets, spacing them 3 inches apart. Flatten slightly and bake for 9-11 minutes until golden around the edges and still slightly gooey in the center (they will set as they cool). Let cookies cool for 1 minute on the baking sheet.
