Gingerbread Cake Ingredients

The most important ingredient in your gingerbread cake is ginger! We're using freshly grated ginger and ground ginger for tons of ginger flavor. You can grate your own ginger or buy your own pre-made. But trust me, you don't want to leave it out. 

One of the reasons this cake is so moist is because it uses dark brown sugar, un-sulfured molasses, buttermilk, and a little bit of oil. I'm using canola oil which has the most neutral oil, but you could also use vegetable oil. 

Make sure your molasses is un-sulfured and not black-strap molasses which is very bitter and too strong of a flavor for baking. 

Another key ingredient of this recipe is buttermilk! Did you know that buttermilk is often used in baking because the acidity breaks down the gluten protein, resulting in a more tender cake? It's true. If you find that you do not have or cannot get access to buttermilk, you can make your own buttermilk substitute. 

How to Make Gingerbread Cake Step-By-Step

1. Preheat your oven to 335°F (170°C). Bring your buttermilk, eggs, and coffee to room temperature. Measure out all of your ingredients by weight with a food scale. I do not recommend converting this recipe to cups because you can accidentally add too much flour which will make your cake dry. 
2. In a large bowl, add your molasses, oil, coffee, vanilla, melted butter, eggs, freshly grated ginger, and buttermilk. Whisk everything together to break up the egg yolks and combine, and then set it aside.
3. In the bowl of your stand mixer, add the AP flour, brown sugar, cinnamon, powdered ginger, salt, and baking soda. Add the paddle attachment and mix on low for a few seconds to combine. I’m using my Bosch Universal Plus mixer, you can also use a hand mixer or even a whisk for this cake.
4. While mixing on low, add in your wet ingredient mixture and mix it until it's just combined (takes about 10-15 seconds). Mix with a spatula to make sure there are no pockets of flour.
5. Prepare three, 6″x2″ cake pans or two, 8″x2″ cake pans with cake goop or your preferred pan release.
6. Divide the batter into your greased cake pans. I like to weigh my pans with a scale to see if I divided the batter evenly.
7. Bake at 335°F (170°C) for 35-40 minutes (for 6″ pans, less for 8″ pans).
8. Remove your cakes from the oven once the tops are set and a toothpick comes out clean. Let your cakes rest in the pans for 10-15 minutes or until the pans are just barely warm.
9. Flip the cakes out onto a cooling rack. Wrap them in plastic wrap to cool at room temperature until you are ready to stack, or freeze the cakes for 30 minutes. Do NOT stack warm cakes. You can wrap and freeze these cakes for a few days before they lose too much moisture.

I made brown sugar Swiss meringue buttercream to go with this cake because I love how silky and smooth it is, but this cake would also go great with cream cheese frosting, whipped cream frosting, ermine buttercream, or my easy buttercream recipe.

How to Make Brown Sugar Swiss Meringue Buttercream

1. Bring two inches of water to a simmer over medium-high heat. Once it's simmering, reduce the heat to medium-low.
2. Place your egg whites and brown sugar together in the metal bowl of your stand mixer and whisk to combine.
3. Place the bowl on top of the simmering water and whisk continuously until the grains of sugar are dissolved. Don't walk away or you could accidentally cook your eggs. Pro-tip – (or oops I accidentally multi-tasked and got distracted tip) if you do walk away and see some bits of cooked egg, you can strain it out and then continue with your buttercream. It’s not ruined.
4. Once you cannot feel any grains of sugar, take the egg mixture off the heat and attach it to your stand mixer with the whisk attachment.
5. Turn the mixer onto high and let your eggs whip until you reach stiff, STIFF peaks. Stiff peaks is when the meringue stands straight up from the whisk. This can take 5-15 minutes depending on the strength of your mixer.
6. Because I'm impatient, I like to scoop out my meringue and place it onto a cookie sheet to cool down quickly in the fridge. You can stick the whole bowl in the fridge but it takes much longer. You can't whip in the butter until the meringue is cool or it will melt the butter and you'll be left with brown sugar soup!
7. After about 10-20 minutes, your meringue shouldn't feel warm anymore. Scoop it back into the bowl and start mixing on medium speed while adding in your chunks of room temperature butter. Some people have had issues with their buttercream becoming soupy cause the meringue was too warm.
8. Add in your salt, vanilla, and cinnamon.
9. Increase the speed to high and whip the buttercream until it's light and fluffy and doesn't taste like butter anymore.

Pro-Tip: If your buttercream is too cold and seems like it’s clinging to the sides of the bowl and whisk you can fix it. Remove about 1 cup of the buttercream and place it into a bowl. Microwave it until it’s barely melted. It took me about 30 seconds.

Pour the half-melted buttercream back into the bowl and continue mixing, it should get light and fluffy now. 

How to Make White Chocolate Water Ganache

1. Combine your chocolate and water together and microwave it for about 1 minute until the chocolate begins to melt. Stir until it’s smooth.
2. Add in 1 teaspoon of white food coloring so that the drip is nice and white and not transparent. Set the water ganache aside to cool to about 90ºF. Make sure your cake is cold and your water ganache is cooled, or it will drip too far down the side of the cake.

1. Place your first layer of cake onto a 6″ round cake board or directly onto your cake plate. Spread a thin layer of buttercream on top that is about ¼″ thick. 
2. Repeat with the second layer of cake. Try to keep your layers of buttercream an even thickness.
3. Cover the entire cake with a thin layer of buttercream. This is called the crumb coat. Then place the cake into the freezer for about 15 minutes to firm up the crumb coat.
4. Apply your final coat of buttercream and smooth out the sides and top with a bench scraper and an offset spatula.  
5. Place your cake back into the fridge to chill while you make your water ganache. 
6. Drip the water ganache down the sides of the cake and fill in the center with the leftover ganache. Smooth out any gaps with a spatula or spoon. 
7. Wait until the ganache sets or put the cake into the fridge for 10 minutes before adding your swirls of buttercream. I was not patient and the buttercream ended up pushing some of the ganache over the edges of the cake and ruined my drip a little.
8. I added these cute little gingerbread cookies to the top of my cake. The lines are just piped with melted white chocolate. Super easy and tasty!
