Gingerbread Christmas Brownies with Eggnog Buttercream Recipe
Festive Christmas brownies strike the perfect balance between fudgy and chewy with a crackled top, rich chocolate flavor, and warm gingerbread spices. And for the icing on the cake, they're decorated with an easy 5-minute eggnog buttercream and holiday sprinkles!
Preheat the oven to 350F. Line an 8 by 8-inch baking pan with parchment paper so it hangs over all 4 sides.
Heat the butter in the microwave or a double boiler until very hot. Add the white sugar and brown sugar, and whisk until well-combined (about 2 minutes). Whisk in the vanilla, eggs, and egg yolk until smooth. Add the cocoa powder, flour, salt, instant espresso powder, ginger, cinnamon, allspice, cloves, and black pepper, and stir just until combined, being careful not to over-mix. Stir in the melted chocolate.
Transfer the batter to the prepared pan and spread it out evenly. Bake until the brownies are set along the outside and have puffed, about 25 to 30 minutes. Be careful not to over-bake. Cool to room temperature.
For the Eggnog Buttercream:
Once the brownies are cool, make the buttercream.
Add all ingredients to a large bowl and use a handheld electric mixer to beat until smooth and creamy. Transfer the buttercream to a piping bag fitted with whatever tip you like.
To Decorate the Brownies:
Cut the brownies into 16 pieces. Pipe a rosette of eggnog buttercream on top of each piece, and then decorate with festive sprinkles. Serve.
