Instructions
Preheat the Oven: Preheat oven to 350°F. Grease and line a 9x13-inch baking dish with parchment paper.
Make the Gingerbread Cake: In a medium bowl, whisk together 1 1/4 cups all-purpose flour, 1 teaspoon baking soda, 1 tablespoon ground ginger, 1 teaspoon cinnamon, 1/4 teaspoon ground cloves and 1/4 teaspoon salt. In a large bowl, whisk melted 1/2 cup unsalted butter, 1/2 cup packed light brown sugar, 1/2 cup molasses, and 1 large egg until smooth. Stir in 1/2 cup hot water, then fold in dry ingredients just until combined. Spread batter evenly in the pan and bake for 15–18 minutes, or until a toothpick comes out clean. Cool completely, then trim into rectangular layers to fit your serving dish if needed.
Prepare the Molasses Mousse: In a large bowl, beat 1 (8-ounce) block cream cheese, softened, 1/3 cup powdered sugar, 1/3 cup packed light brown sugar, 1/4 cup molasses, 1 teaspoon pure vanilla extract, 1/2 teaspoon cinnamon, 1/4 teaspoon ground ginger, 1/4 teaspoon salt until smooth. In a separate chilled bowl, whip 1 3/4 cups heavy whipping cream until stiff peaks form. Gently fold whipped cream into the molasses mixture in two additions until fluffy and smooth.
Assemble the Layers: In a deep dish or loaf pan, alternate layers as follows:
Gingersnaps
Molasses mousse
Gingerbread cake
More mousse
Gingersnaps or another cake layer (if you have enough)
Drizzle with dulce de leche
Finish with a final mousse layer
Smooth the top, cover tightly with plastic wrap, and refrigerate for at least 6 hours or overnight.
Make the Whipped Topping: In a chilled bowl, whip 3/4 cup heavy cream with 2 tablespoons powdered sugar and 1/2 teaspoon pure vanilla extract until soft peaks form. Spread over the chilled cake and garnish with crushed gingersnaps, cinnamon, or caramel drizzle.
