For the bread pudding: Blend the cream, pumpkin, granulated sugar, brown sugar, pumpkin pie spice, vanilla extract, eggs and vanilla bean until mixed well.

For the rum sauce: Blend the cornstarch with the water in a small saucepan. Add the cream, granulated sugar, butter and rum and cook over low heat, stirring occasionally, until thick. Serve the sauce with the bread pudding.
