Here's the recipe, from the More-with-Less Cookbook:
Bake at 350 for 10-12 minutes
1/2 cup margarine
1 cup sugar
Beat well. Sift together:
1 1/2 cup flour
1 tsp. baking powder
1/2 tsp. salt
1 tsp. baking soda
1 tsp. cinnamon
1/2 tsp. allspice
Add to creamed mixture alternately with:
1/2 cup milk
2 cups rolled oats
This is where you stir in any "add ins" you might want. The recipe calls for chopped dates, coconut, and walnuts, but growing up my mom always made it with raisins. I, of course, add chocolate chips. (Fair warning: I added a whole bag of chocolate chips, which overpowered the subtle cinnamon flavour. Next time I'll add no more than 1 cup).
The recipe is said to make 6 dozen, but I found that is only make 4 dozen. (Only should be in scare-quotes, 4 dozen is more than enough!) This would change with the size you make your cookies, but I'm pretty happy with the size these ones are.
These cookies are great anytime, but I especially love them for breakfast. (What? Chocolate's a breakfast food!)
