The serving size for these homemade lactation brownies is 1 square, and you can eat them any time of day. You can enjoy one or two of these each day depending on your needs - and your sweet tooth! There are 16 servings in each batch so I recommend storing half in the freezer to stay fresh. If you want to eat more than 2 per day, I'd recommend cutting the sugar in this recipe by half so that you're not eating too much added sugar.
