Pumpkin Snickerdoodles

Just in time for Canadian Thanksgiving. Just discovered this recipe in Blogville and I've already made it twice. These are a soft, pillow-like cookie with just the right amount of pumpkin and spice.
I slightly underbaked them the first time, I made them and they turned out great.

Pumpkin Snickerdoodles
1/2 cup butter
1/2 cup shortening
1/2 cup brown sugar
1 cup white sugar
3/4 cup unsweetened pumpkin puree
1 large egg
3 1/4 cup all purpose flour
2 tsp baking powder
1 tsp baking soda
1/2 tsp cinnamon

Mix together first 6 ingredients. Mix dry ingredients and add to wet and mix well. Chill dough about 30 minutes. Roll into balls the size of small walnuts. In a separate bowl, mix 1/2 cup white sugar with 1 Tbsp. cinnamon and 1/2 tsp ground ginger. Roll ball in sugar mixture and bake at 375 F for 7-8 minutes until lightly browned but still soft.
