Honey Matcha Castella Cake

So back to my layer cake.I’m getting a little bored with just filling my cakes with buttercream or jam. It’s simple. It’s expected. And while it is great and easy if you don’t have a lot of time, it doesn’t add a ‘wow factor’ to the cake. So since I am trying to venture more and more into the world of French Entremets, I decided to make my layer cake a bit more of a fusion cake than it already was by adding a matcha mousse between the cake layers to give the cake height and flavor without overwhelming the eater with sugary sweetness.I don’t have much experience making mousses, so while the process is incredibly simple, I definitely had a moment of panic when things weren’t as I originally imagined them. There is a point where your mousse batter is incredibly liquid, and you know you only have a certain amount of time before the gelatin really kicks in…In the end what I did, since I don’t have any cake rings, I lined my 6″ cake pan with plastic wrap, put in my first layer of cake and firmly pressed it against the bottom of the pan before pouring in about a 1/2″ layer of the mousse. Since it was so liquid, I didn’t want to continue stacking my cake for fear that the next cake layer would sink through the mousse and cause a disaster, so I stuck the cake into the freezer for about 10 minutes to get the mousse just cold enough to support the next layer of cake. I ended up adding 4 layers of cake with 3 layers of mousse, which was the perfect amount to fit in my cake pan.

I did end up with about two cups of extra mousse, and loath to throw it out I filled one of my silicon molds with part of it and made mini parfaits with the rest of it to give to my family that evening.After leaving my cake in the freezer overnight, I woke up and sort of randomly threw things in my kitchenaid until I reached the frosting I was dreaming of, end then spent a very enjoyable hour frosting and taking pictures of my cake.

Honey Castella Cake Recipe (Adapted from The Sweet Spot Cookbook)

Ingredients:1/4 cup olive oil
1 1/2 cup flour
1/2 teaspoon salt
7 large eggs
3 large egg yolks
1 1/2 cups sugar
1/4 cup honeyDirections:1) Preheat your oven to 350 degrees and prepare four 6″ cake pans.
2) Sift the flour and salt into a bowl and set aside.
3) In a large bowl, whisk the eggs, yolks, sugar and honey, and set over a saucepan of simmering water. Whisk constantly until the sugar is dissolved and the mixture is warm to the touch–about 10 minutes.
4) Place the egg mixture into the bowl of a stand mixer and whip on medium-high speed for about 10 minutes, or until it is light and fluffy. Fold in the dry ingredients gently.
5) Place about 1 cup of the batter into a bowl and whisk with the oil until homogenous. Pour this into the rest of the batter and fold to combine.
6) Divide between the cake pans and place in the oven for about 10 minutes, before turning the heat down to 300 and cooking for another 15 minutes or so. Remove and cool completely.

Assembly:

1) Prepare the castella cake, let cool, then cut two of the 6″ cakes in half.
2) Prepare the matcha mousse.
3) Line a 6×3″ cake pan with plastic wrap and place one layer of cake in the bottom. Add in a layer of mousse and place int he freezer for about 10 minutes before adding on the next layer of cake.
4) When all four cake layers have been used, place in the freezer overnight.
5) Remove the cake from the pan, remove the plastic wrap, and frost with the buttercream.
6) Decorate as desired–I toasted some sliced almonds and sprinkled them on the bottom and top of the cake with some fresh raspberries.
