My Mother's Shoo Fly Pie was always one of my favorite's growing up. This recipe was handed down to me many years ago. My adult twin sons still request Shoo Fly Pie for their birthday. My 3 year old Grandson also loves it. He likes to help me bake as my little helper. We now make them in a cupcake instead of a pie for him. He likes to put the crumbs on the top and then watch them grow in the oven. Such a simple recipe and such a joy to make!
