Just putting this recipe up again for all the BF mums on here, I'm having trouble with my supply atm and found this published by Deb back in 2010. (thanks Deb!

Lactation Boosting Oatmeal, Chocolate Chip & Linseed Cookies
1 cup butter or margarine
1 cup sugar
1 cup brown sugar
4 tablespoons water
2 tablespoons 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 I use a whole packet J) chocolate chips (milk or white chocolate both taste yummy)
2 tablespoons brewer’s yeast (be generous)
Preheat oven to 180c (fan forced) 200? (regular oven). Mix together 2 tbs of linseed meal and water. Set aside. Cream butter and sugar. Add eggs one at a time, mix well. Stir linseed mixture and add with vanilla to the butter mix. Beat until blended. Sift together dry ingredients, except oats and chips. Add to butter mixture. Stir in oats, then chips. Scoop or drop onto non stick baking sheet, or one lined with baking paper. Bake approximately 12 minutes.
Linseed meal can be found in the health food aisle of your supermarket or at health food stores. Brewer’s yeast can be found at health food stores. It MUST be brewer’s yeast - NO substitutions.
