Big Batch Chip Chop Cookies

In a blender or food processor, gradually grind (chop!) the oatmeal into a coarse flour. Set aside. In a separate bowl, combine flour, baking powder, baking soda and salt. Set aside.
Cream together butter and sugars in a mixing bowl. Add eggs and vanilla and mix well. Gradually add flour mixture. Add ground oatmeal, You may need to begin stirring by hand at this point. Add chips and m&m bits. Sometimes I just throw out the whole batch out onto the counter and knead it together by hand. It is a very stiff dough. (Stiff dough = soft cookies.)
At this point, if desired you can drop rounded spoons of dough onto cookie sheets and bake in a preheated 350u0b0F degree oven for 7-9 minutes until lightly browned.
Or, on a sheet of plastic wrap, form dough into 2-inch (approximately) diameter logs. Roll plastic wrap around dough and fold over ends. Place logs in a freezer bag and place in freezer.
When ready to bake, remove log from freezer. Do not thaw. Preheat oven to 350-F degrees. Unwrap log and slice into 1/2 to 3/4 inch sections. Place sections on cookie sheet and bake for 12-14 minutes (times will vary according to the size of your cookie) or until cookies are lightly browned and centers are barely set. Do not over-bake. Allow to rest for a minute or two before removing to a cooling rack or a plate to serve warm.
