Perfect your Christmas with our scrumptious Gingerbread Cake with Brown Butter Frosting, a cozy holiday treat of pure comfort and indulgence.
Preheat the oven to 350°F (180°C) and butter a 10-inch cast iron skillet. Set aside.
Add the egg and vanilla and beat until combined, then alternate adding the flour mixture and milk mixture, a little at a time, until just smooth and combined.
Spread evenly into the skillet and bake for 25-30 minutes, until a toothpick inserted in the center comes out clean. Let cool completely in the skillet.
Melt the butter medium saucepan over medium-low heat and let cook for 5-10 minutes, until the butter turns a toasty brown color and has a nutty aroma. (It will foam a lot so you can stir it a bit to check the color.)
