These Frosted Gingerbread Brownies start with my beloved gingerbread brownie base and get a decadent upgrade with a creamy gingerbread ermine frosting. The brownies are soft, tender, and perfectly spiced, while the frosting adds a silky, sweet layer that melts in your mouth!
Preheat oven to 350°F. Line a 9×9-inch baking dish with parchment paper. Set aside.
In a large bowl, combine butter and brown sugar. Stir well.
Mix in eggs, molasses, and vanilla.
In a medium bowl, whisk together the flour, ginger, cinnamon, baking powder, and salt.
Gradually stir the flour mixture into the butter and egg mixture until completely combined.
Spread the batter evenly into the prepared pan. Bake for 28-33 minutes, or until the edges are set and the center is no longer jiggly.
Allow brownies to cool completely before adding the frosting.
Gingerbread Ermine Frosting
While brownies are cooling, prepare the Gingerbread Ermine Frosting. In a medium saucepan over medium heat, whisk together the milk and flour. Cook, whisking constantly, for 3-5 minutes, or until no lumps remain and the mixture thickens and resembles a very thick pudding. It should coat the back of a spoon.
Remove the pan from the heat and let the mixture cool to room temperature. (Cover with plastic wrap pressed directly on top to prevent a skin from forming.)
In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugar on medium speed until light and fluffy (2-3 minutes). Stop the mixer and use a rubber spatula to scrape down the sides of the bowl.
Add the cooled milk mixture and gingerbread spice mix to the bowl of the stand mixer. Beat on medium-high speed until the frosting is light and fluffy (2-3 minutes), pausing to scrape down the sides of the bowl as needed.
Switch to the whisk attachment. Add vanilla and mix on high for 7-8 minutes, or until the frosting is smooth and creamy.
Spread the frosting over the cooled gingerbread brownies, slice, and serve.
