Not sure where I originally found this recipe but it has been a staple in my household. Whenever we're in the mood for cookies I whip these up. They're very easy, bake quickly, and composed of ingredients that you likely already have on hand.
2Dice up the chocolate bars into smaller pieces. Set aside.
3Mix butter and sugar. Add the egg. Mix well.
Add in all dry ingredients & mix. This should be a really thick sticky batter. Add a dash of milk, to thin it out ever so slightly. Add in all the chocolate pieces, and stir to incorporate.
4Roll cookies into balls and place on a parchment lined cookie sheet. These cookies are meant to be big, but you can make them any size you'd like.
5Bake for EXACTLY 11 minutes. Baking time is crucial for this recipe. Note: They will not look done when you take them out. Remove from oven and allow to cool sufficiently. If the cookies are not properly cooled they will fall apart.
