I never gave the name aggression cookies much thought but according to the many recipes posted online the name comes from the fact that one can get their aggressions and stress out while making these cookies, the longer you knead the better! Put some serious elbow grease into it. I remember it was fun as a child to get my hands all messy with the cookie dough and knead away.
1 cup butter (unsalted and softened)
1 cup white flour
1 cup brown sugar
2 sugar old fashioned oats (don't use quick cook oats)
1/2 teaspoon vanilla
1 teaspoon baking soda
Put all the ingredients in a bowl and mash with your hands until mixed very well. Roll into 1 inch balls and place on an ungreased cookie sheet 2 inches apart. Press the cookies flat with the back of a glass. Bake at 350 degrees for 10 minutes or until lightly golden in colour. Remove from heat and let cool COMPLETELY before removing from cookie sheet or else the cookies will crumble. This recipe makes anywhere from 20 - 60 cookies depending on how large you make your cookies.
