1To make the crust, add together graham cracker crumbs, brown sugar and butter. Mix well.
Grease a 9 inch spring-form pan and press the crust mixture evenly over the bottom.
Bake 5 minutes at 350 degrees. Remove from oven and let cool.
2To make the filling, use a mixer to beat the cream cheese in a bowl. While continuously mixing, add the eggs (one at a time), the sugar (slowly), the pumpkin, the flour and the spices.
3Pour mixture onto the crust and bake at 350 degrees for approximately 1 hour or until the mixture has set and a toothpick comes out clean when inserted into the center of the cheesecake. Remove from oven and let cool.
