this is on my list to try; I find most ATK recipes quite good
Classic Gingerbread Cake
From America's Test Kitchen Season 12: Fall Classics
Makes one 8-inch square cake, serving 8 to 10
This cake packs potent yet well-balanced, fragrant, spicy heat. If you are particularly sensitive to spice, you can decrease the amount of dried ginger to 1 tablespoon. Guinness is the test kitchen's favorite brand of stout. Avoid opening the oven door until the minimum baking time has elapsed. If your cake pan has thin walls, you might want to wrap it with premade cake strips or make your own from cheesecloth and foil. This extra insulation will help ensure that the edges of the cake don't overbake. Serve the gingerbread plain or with lightly sweetened whipped cream. Leftovers can be wrapped in plastic wrap and stored at room temperature for 2 days.
INGREDIENTS
3/4cup stout (see note)
1/2teaspoon baking soda
2/3cup mild molasses
3/4cup (5 1/4 ounces) packed light brown sugar

INSTRUCTIONS
1. Adjust oven rack to middle position and heat oven to 350 degrees. Grease and flour 8-inch square baking pan.
2. Bring stout to boil in medium saucepan over medium heat, stirring occasionally. Remove from heat and stir in baking soda (mixture will foam vigorously). When foaming subsides, stir in molasses, brown sugar, and granulated sugar until dissolved; set mixture aside. Whisk flour, ground ginger, baking powder, salt, cinnamon, and pepper together in large bowl; set aside.
3. Transfer stout mixture to large bowl. Whisk in eggs, oil, and grated ginger until combined. Whisk wet mixture into flour mixture in thirds, stirring vigorously until completely smooth after each addition.
4. Transfer batter to prepared pan and gently tap pan against counter 3 or 4 times to dislodge any large air bubbles. Bake until top of cake is just firm to touch and toothpick inserted into center comes out clean, 35 to 45 minutes. Cool cake in pan on wire rack, about 11/2 hours. Cut into squares and serve warm or at room temperature.
