this is the recipe I use and (and have made notes about changes on it - printed for friends a few times) - I got this off here somewhere


Housepoet’s Famous Lactation Boosting Oatmeal, Chocolate Chip & Flaxseed cookies
Serves: 6 dozen cookies
Preparation time: 15 minutes
Ingredients:
• * 1 cup butter (~240g) or marg(~230g)
• * 1 cup sugar
• * 1 cup brown sugar
• * 4 tablespoons water
• * 2 tablespoons flaxseed meal (can be found at any local health food store) (also called Linseed meal)
• * 2 large eggs
• * 1 teaspoon vanilla
• * 2 cups flour
• * 1 teaspoon baking soda
• * 1 teaspoon salt
• * 3 cups oats, thick cut if you can get them
• * 1 cup or more chocolate chips
• * 2 tablespoons of brewers yeast (be generous) (IT MUST BE BREWERS YEAST, NO SUBSTITUTIONS)
Directions:
• * Preheat oven at 375 degrees F (190C).
• * Mix together 2 tablespoons of flaxseed meal and water, set aside for 3-5 minutes.
• * Cream (beat well) margarine and sugar. Add eggs one at a time, mix well.
• * Stir flaxseed mixture and add with vanilla to the margarine mix. Beat until blended.
• * Sift together dry ingredients include yeast, except oats and chips. Add to margarine mixture. Stir in oats then chips.
• * Scoop or drop onto baking sheet, preferably lined with parchment or silpat. The dough is a little crumbly, so it helps to use a scoop.
• * Bake 8-12 minutes, depending on size of cookies. (Approx 25 – 30 min for slice size)
I make mine into 2 slices, just make sure the slice is no thinker than a cookie. It’s quicker and easier that way, especially with kiddies running around

You don’t have to use choc chips – I’ve used a combination of choc chips & sultanas, choc chips & crushed nuts or straight choc chips, straight sultanas. You can use whatever you like instead of the choc chips.
