From http://bakingbites.com/2007/11/chocolate-pumpkin-pie/

3 large eggs, room temperature
1  15-oz. can pumpkin puree (about 1 1/2 cups)
1 cup brown sugar
1/4 cup unsweetened cocoa powder
1 tsp ground cinnamon (or pumpkin pie spice)
1/2 tsp ground allspice
1/4 tsp ground cloves
1/8 tsp freshly ground nutmeg
1/2 tsp salt
1/2 tsp vanilla extract
2/3 cup milk (low fat is fine)


For pie it would be 15 mins at 425 then 30 mins at 350.  So probably
50 mins at 350.
