Pre-heat oven to 375F degrees.
Unroll 2-17.5 ounce cans cinnamon rolls on baking parchment. Reserve icing packs for later. Separate into 10 rolls. Cut each roll into 8 pieces; place in lightly buttered 13x9-inch (3 quart) glass or ceramic baking dish.
2 17.5 oz. cans refrigerator cinnamon rolls
In a medium bowl, beat eggs, pumpkin, pumpkin pie spice, brown sugar, evaporated milk and ginger until well blended. Pour evenly over cut rolls in dish. Sprinkle pecans over top.
4 large eggs, 1 cup canned pumpkin puree, 1 tsp pumpkin pie spice, ⅓ cup packed brown sugar, 1 5 oz. can evaporated milk, ⅓ cup crystallized ginger, ½ cup coarsely chopped pecans
Bake uncovered 30 minutes. After 30 minutes, cover baking dish with foil and bake covered 10 minutes longer (this prevents the top from over-browning but allows the bottom to continue to bake).
Remove from oven to cooling rack. Uncover; cool slightly, about 10 minutes. Meanwhile, whip 16 ounces cream with vanilla and sugar, to taste.
16 oz. whipping cream, Vanilla and sugar
Cut into individual servings and drizzle glaze over top (if making your own glaze, pour glaze into plastic sandwich bag, cut small hole in corner and squeeze over individual pieces).
Serve with dollop of whipped cream topped with grated crystallized ginger.
Additional crystallized ginger for grating over top of whipped cream
This recipe can be made a day ahead. Store at room temperature without the glaze or whipped cream for up to a day before serving.
