Preheat oven to 325 degrees F.
Grease and lightly flour the Gingerbread House Bundt Pan. (I prefer to use Baker’s Joy because it’s much faster and my cases always release perfectly when I use it)
In a medium bowl whisk together dry ingredients: Flour, cornstarch, ginger, cinnamon, nutmeg, salt, and baking powder. Set aside.
Next cream your sugars (white and brown) together with the softened butter, using a hand or standing mixer, until light and fluffy.
Add eggs one at a time and beat in thoroughly after each addition. Make sure to scrape down the bowl as you go so all ingredients are combined well.
Next add ½ the dry ingredients to the batter and mix in on low, then ½ of the milk. Mix in and finish adding flour and milk alternately until combined. Be sure not to over mix.
Lastly, fold in vanilla (and molasses if using) until incorporated.
Spoon the batter into the prepared Gingerbread House Bundt Pan evenly. Place on a baking sheet and bake for 55-66 minutes until a toothpick inserted in the center comes out clean.
Cool upside down in bundt pan for 10-15 minutes. Place a platter or serving tray on the open part (bottom of the bundt pan) and flip over while holding so that the bundt pan is upright. Carefully lift the bundt pan off the gingerbread house so that it’s sitting upright on the platter of your choice.
Allow it to cool completely then cover with plastic wrap or decorate right away with icing, candies and powdered sugar.
