Lactation cookies? When I eat them within a day my boobs are bursting. There's a recipe in the BB fact sheets. You need brewers yeast, rolled oats and linseed meal. You can add the brewers yeast to anything. I was sprinkling it in my oats for breakfast with a bit of linseed meal. You can add it to cakes, cookies, whatever you like. I usually add 2-4tbsp to my cookies.
