**Note: 6 Jumbo cookies too much? This recipe is incredibly easy to reduce. Simply halve the ingredients- 2 tbsp butter, 1/8 cup brown sugar, 1 tbsp granulated sugar, 1 large egg yolk, 1/2 tsp vanilla, 1/3 cup flour, 1/4 tsp baking soda, 1/4 tsp salt, eyeball the chocolate. It’s also easy to double. Just sayin’. 😉
