Notes
Ingredient Substitution Notes
Salted Butter. unsalted butter & coconut oil are both good substitutes.
Granulated sugar. Use organic cane sugar if you'd like.
Light brown sugar. dark brown sugar or coconut sugar are great choices.
Mini chocolate chips. I prefer mini chips because they spread well throughout the dough so there's chocolate in every bite. You can use regular-sized chips, chopped chocolate bars, etc.
StoreIf you have leftovers, cover the top of the mug with plastic wrap and store it in the fridge for up to 3 days. Reheat in the microwave for a few seconds.
