Ingredients

Scale

Batter Ingredients

  • 1 cup (2 sticks / 227 g) unsalted butter, melted
  • 1 ½ cups (300 g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 2 tablespoons molasses
  • 1 teaspoon vanilla extract
  • 2 ½ cups (312.5 g) all-purpose flour
  • 1 tablespoon ground ginger
  • 2 teaspoons cinnamon
  • 1 teaspoon baking powder
  • ½ teaspoon kosher salt

Frosting Ingredients

  • 1 cup (245 g) whole milk
  • 5 tablespoons all-purpose flour
  • 1 cup (2 sticks / 227 g) unsalted butter, room temperature
  • 1 cup (200 g) light brown sugar, packed
  • 1 teaspoon gingerbread spice mix (typically a blend of cinnamon, ginger, cloves, nutmeg)
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven and prepare pan. Preheat the oven to 350°F (175°C). Line a 9×9-inch baking dish with parchment paper and set aside.
  2. Combine butter and sugar. In a large bowl, mix the melted butter with the packed light brown sugar until well combined.
  3. Add wet ingredients. Stir in the eggs one at a time, then add molasses and vanilla extract, mixing thoroughly after each addition.
  4. Mix dry ingredients. In a separate medium bowl, whisk together the flour, ground ginger, cinnamon, baking powder, and kosher salt until evenly combined.
  5. Combine wet and dry mixtures. Gradually add the dry ingredients to the wet mixture, stirring until the batter is fully incorporated and smooth.
  6. Bake the brownies. Pour the batter evenly into the prepared baking pan and bake for 28-33 minutes, or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs (center should not be jiggly).
  7. Cool the brownies. Remove from oven and allow the brownies to cool completely in the pan before frosting.
  8. Prepare the frosting base. While brownies cool, in a medium saucepan over medium heat, whisk together the milk and flour. Cook, whisking constantly for 3-5 minutes until the mixture thickens into a very thick pudding and is smooth with no lumps. It should coat the back of a spoon.
  9. Cool the milk mixture. Remove the saucepan from heat. Transfer the thickened milk mixture to a bowl, cover with plastic wrap pressed directly onto the surface to prevent skin formation, and let it cool to room temperature.
  10. Cream butter and sugar. In the bowl of a stand mixer fitted with the paddle attachment, cream the room temperature butter and packed brown sugar on medium speed for 2-3 minutes until light and fluffy. Scrape down the sides of the bowl.
  11. Combine frosting ingredients. Add the cooled milk mixture and gingerbread spice mix to the creamed butter and sugar. Beat on medium-high speed for 2-3 minutes until the frosting is light and fluffy, scraping down sides as needed.
  12. Add vanilla and whip frosting. Switch to the whisk attachment. Add vanilla extract and whip on high speed for 7-8 minutes until the frosting becomes smooth, creamy, and spreadable.
  13. Frost the brownies. Spread the frosting evenly over the cooled gingerbread brownies. Slice into squares and serve.

Notes

  • The gingerbread spice mix can typically be made by combining cinnamon, ground ginger, cloves, and nutmeg; adjust proportions to taste.
  • Ensure the milk and flour pudding mixture is cooled completely before adding to the butter to prevent melting and separation.
  • Line the baking pan with parchment to make removal and slicing easier.
  • Brownies continue to set as they cool; avoid overbaking to keep a moist center.
  • Store frosted brownies in an airtight container in the refrigerator for up to 4 days.
