Oatmeal cookies aren't my favorite cookie. But, The Joy of Cooking has a great oatmeal cookie recipe. They are crispy but still have a cookie texture. The three and I recently made the cookies and shared them with friends and family.
I am learning how to do the cooking and baking stint with the children. One thing I've found helpful is to give each one of them their own utensil. This kept them happy and engaged. It also gives them something to lick when we are finished.
After we were finished, this mama was very happy when her son, completely unprompted, started wiping off our work area. A good cook is a good cleaner.
