1/4 c. flour
Add brown sugar, cinnamon, nutmeg and ginger.
Stir in eggs and half and half.
Bake at 350 degrees for 30 minutes. While the pie is baking, make the streusel topping by combining the ingredients and mixing until it resembles crumbs. (I like to leave some larger chunks in mine)
Remove pie from oven and sprinkle with streusel topping. Continue baking for 20 minutes.
Serve with vanilla ice cream or whipped topping.
