Instructions

Raspberry Curd

  1. Place a fine-mesh sieve over a heat-proof bowl.
  2. In a medium, heavy-bottomed saucepan, melt the butter over medium heat. Add the berries and any juices, sugar, lemon juice, egg yolks and salt.
  3. Cook over medium heat, stirring frequently and mashing the berries until thickened (5-10 minutes).
  4. Strain through the prepared sieve, mashing the berries with a spoon or rubber spatula.
  5. Discard the seeds and other solids.
  6. Give the curd in the bowl a stir, let cool slightly and press plastic wrap onto the surface to prevent it from forming a skin.
  7. Cover and refrigerate until completely cooled.

Cake

  1. Preheat oven to 325°F.  
  2. Finely chop chocolate and add it to a bowl with hot coffee or hot water. Let mixture stand, stirring occasionally, until chocolate is melted and mixture is smooth. Let cool.
  3. In a large bowl, sift together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
  4. In the bowl of a stand mixer, beat eggs until thickened slightly and lemon coloured (about 3 minutes). Add oil, yoghurt, vanilla, and cooled, melted chocolate mixture to eggs, beating until combined well. Add flour mixture and beat on medium speed until just combined.
  5. Spray two 8-inch round pans with baking spray containing flour (I use Bak-Klene). Line bottoms with rounds of parchment paper and spray the paper. Divide batter between the pans and bake in middle of oven until cake springs back when pressed in the center, (40-50 minutes).
  6. Cool layers in pans for 15 minutes on racks. Run a thin knife around edges of pans and invert layers onto wire racks. Carefully remove parchment paper and cool layers completely. Cake layers may be made 1 day ahead and kept, wrapped well in plastic wrap, at room temperature.

Assemble Cake:

  1. Torte each cake layer so you have four layers.
  2. Place a cake layer on a cake board on a turntable. Pipe with a layer of frosting, followed by a thin layer of raspberry curd. Repeat with other layers, finishing with a cake layer. Stick a few skewers down through the layers to hold them vertical. Refrigerate until firm (30-60 minutes).
  3. Crumb coat: frost the cake with a thin layer of frosting. You should be able to remove the skewers at this point. Refrigerate until firm (15-30 minutes).
  4. Tint 1/2 c of frosting to make soft pink (I used Americolor Burgundy), 1/8 c to dark burgundy (Americolor Burgundy – just use more) and 1/8 c soft brown/grey (I used Americolor Taupe). Attach a coupler to the bag for the pink frosting, tip #1 to the bag for the burgundy frosting and tip #3 to the bag for the brown/grey frosting. Add the respective frostings to the bags.  
  5. Make cherry blossoms: Cut up 30 2″ parchment squares; use one for each blossom, fixing the parchment to a turntable with a small dab of frosting. Using the pink frosting and tips #101, #102 and #103, pipe six #101 five-petal blossoms, four #102 blossoms and three #103 blossoms (the thick side of the tip goes toward the centre of the blossom). Add 1/2 c plain white frosting to the bag that is low largely empty of the pink frosting and repeat. This will provide a nice variety of pink & white blossoms. Use the dark burgundy frosting to dot the centre of each blossom. Freeze the flowers until ready to use.
  6. Frost the cake with the final layer of frosting, getting it as smooth as you can. Refrigerate until firm (15-30 minutes).
  7. Using the brown/grey frosting, pipe the branches on the side of the cake and score them with a toothpick to create realistic bark. You may want to sketch the approximate locations of the branches using the toothpick first. Attach the blossoms using a bit of the appropriately coloured icing. 

Swiss Meringue Buttercream

  1. Add egg whites, sugar and salt to the bowl of a stand mixer and whisk briefly. It’s important that the bowl be completely free of any fat, or your meringue won’t whip, so you may want to wipe it down first with a diluted mixture of vinegar or lemon juice and water before wiping it dry with paper towels.
  2. Place the bowl over a pan of simmering water, making sure the water does not touch the bowl.
  3. Whisk the egg whites occasionally until they warm up, then whisk constantly as the temperature rises. Heat the mixture until it reaches 160ºF or until it doesn’t feel grainy between your fingers. 
  4. Transfer the bowl to a stand mixer, and beat with a whisk attachment until you get glossy, room temperature peaks. Tip: hold a couple of bags of frozen peas or corn against the outside of the bowl to bring the temperature down.
  5. Switch to the paddle attachment. With the mixer running on low, add small dollops of room temperature butter, one at a time. Take your time with this –  let the butter incorporate fully before you add the next piece, which will take 10-15 minutes. Don’t panic if the mixture gets soupy. Just keep beating. You can’t overbeat it and it will come together in the end. 
  6. Add the vanilla extract.
