Moist and perfectly spiced old-fashioned gingerbread layer cake is frosted with mascarpone cream and decorated with lebkuchen cookies is simply out of this world. It makes a perfect Christmas cake.
Things to prepare before you start preparing the cake batter:
Mix milk with vinegar to make a "buttermilk". Let it sit for 5 minutes. You will see some small curds after that
Preheat the oven at 350 F (180 C) for a conventional oven. For convection oven, you may need to lower temperature by 15-20 degrees
You can bake this cake in 3 6-inch cake pan, or 2 6-inch cake pan, or one 6-inch cake pan. Oil your pan and then lightly flour them and shake off excess flour, for easier release later. You can also use a non-stick spray with flour
Please make sure the butter,eggs, and milk are at room temperature. Butter should be soft but not melty
Prepare the cake batter:
Mix all the dry ingredients and set aside
Place butter and sugar in a mixing bowl. I use a stand mixer fitted with a paddle attachment. Cream the butter and sugar until creamy and fluffy on medium speed. Add the molasses and vanilla and continue to beat for another 30 seconds and gradually add in eggs, in 4-5 addition. Make sure it's well-combined before adding more
Switch to a low speed and add 1/3 of the flour mixture and alternate with 1/3 of the homemade buttermilk. Stop the mixer. The batter won't be fully combined yet, but that's ok. Use a spatula and manually fold everything to combine. Take care not to overmix. As long as you don't see any more pockets of flour, the batter is ready
Divide the batter equally into the prepared pans if you use multiple pans. I recommend using a scale to weigh each pan after that to see if you divide the batter equally, if not, you can always transfer some batter around to make sure they have roughly the same amount. Smooth the batter after that and give them a few tap on the counter to pop any large bubbles inside the cake batter
Baking:
Place them on the middle rack and bake for 20-35 minutes if you bake in 3 pans, 40-45 minutes if you bake in two pans, and about 60 minutes if you bake in one pan or until a cake tester inserted into the cake comes out clean with no wet crumbs
Cooling down:
Let the cakes cool down in the pan for 15 minutes and then invert them out onto a cooling rack to let them cool down completely. If you are not assembling the cake on the same day, wrap each cake with cling wraps to prevent them from drying out. They can be kept at room temperature for no more than 2 days
Assembling:
Prepare simple syrup by dissolving sugar in hot water
Mascarpone is soft and doesn't need to be softened at room temperature. If you use cream cheese, it needs to be softened at room temperature
Add mascarpone, softened butter, icing sugar in a mixing bowl. Use a hand mixer or stand mixer to cream them until combined. Add the heavy cream and whip until just firm. Do not overbeat the heavy cream or it will turn grainy. Cover and keep in the fridge while you prepare other things
If you bake in one pan, trim off the dome top and then slice the cake horizontally into three slices, same thickness. Use a cake leveler to help you if you have one
Put a bit of the frosting on a cake stand or whatever you are using to display the cake. Put the first layer of cake. Brush the cake with some simple syrup. Spread some cream on top with an offset spatula and then top with the second layer and repeat the same step until you lay the third layer. Cover with some cream on top and the side of the cake. Use the offset spatula to "tidy up" the cream. I'm not fully frosting the entire cake to get that semi-naked look
Use the lebkuchen cookies to decorate the side of the cake. Transfer the remaining cream into a piping bag fitted with a nozzle of your choice and pipe around the edge of the cake. Sprinkle with desiccated coconut on the center of the cake. Chill in the fridge for about an hour before serving
