Ingredients

  • 1

    stick and 3 tablespoons of unsalted butter, softened

  • 1

    and 1/2 cups granulated sugar

  • 4

    large egg whites

  • 2

    teaspoons vanilla extract

  • 2

    cups unbleached all-purpose flour

  • 2

    and 1/2 teaspoons baking powder

  • 1/2

    scant teaspoon salt (I used fine sea salt.)

  • 2/3

    cup milk, at room temperature (I used 2 percent.)

  • 1/3

    cup coconut milk, at room temperature (I used Thai Kitchen brand.)

Directions

To make the cake layers: Preheat your oven to 350 degrees. Grease, or use baking spray on, two 9" round cake pans (I used the latter, generously). Line the bottom of the pans with rounds of parchment. Grease the parchment and flour the bottom and sides of the pan, or spray the parchment with baking spray. In a medium size bowl, sift the flour, baking powder, and salt together. Set aside. Stir together the milk and coconut milk in a small bowl. Set aside. In the large bowl of your mixer, using the paddle attachment on medium-high speed, cream the butter and sugar for a few minutes, until very light in color and fluffy. Pour in the egg whites gradually, mixing until they're completely combined, and stop to scrape as needed. Mix in the vanilla. On the lowest speed, add in the dry ingredients alternately with the milk and coconut milk, starting and ending with the dry (three portions of dry, and two portions of liquid). Beat only until the batter looks completely mixed. Divide the batter equally into the two prepared pans, and bake in a preheated oven for about 20 to 25 minutes, or until the top of the cakes no longer look wet and a toothpick inserted in the center comes out clean. Let the cakes cool in their pans on cooling racks for about five minutes then run a thin knife or metal spatula around the edges of the cakes, and invert the cakes out of their pans and onto racks to finish cooling. Peel off the parchment, slowly and carefully, while the cakes are still warm. To make the chocolate ganache: 6 ounces good quality dark chocolate, chopped into small pieces 6 ounces heavy cream Put the chopped chocolate into a bowl. In a small saucepan, gently heat the cream until it's hot but not boiling. Pour the cream into the bowl, over the chocolate. Let it sit undisturbed for a few minutes, then gently stir the cream completely into the chocolate. The ganache should look smooth and silky. Let it cool to room temperature, when it will be ready to use as a filling between the cooled cake layers. Don't cover it until it's at room temperature or cooler. Make the Swiss Meringue Buttercream To assemble and frost the cake, you'll need: 2 cake layers At least one cup of the ganache At least five cups of the buttercream 1 and 1/2 cups of sweetened, shredded coconut Place one cake layer upside down onto a cardboard/cake-board or onto the plate it will be served from. Spread a generous layer of room-temperature ganache on top. Add the second cake layer, placing its flattest surface facing up. Spread about a cup or so of buttercream on the top, and frost a generous layer on the sides. Because the cake will be covered with sweetened coconut, it's not really necessary to try and make the surface or sides of the cake completely smooth. To add the coconut, hold your cake, on its board/plate over a baking sheet. Gently press handfuls of coconut into the sides as you turn the cake until it's completely covered, and then sprinkle more on the top. Scoop up any coconut that falls onto the baking sheet and scatter it on as well. Swiss Meringue Buttercream Yield: ~ 10 cups of buttercream 10 large, fresh egg whites (300 g) 2-1/2 cups (500 g) sugar 3 cups (680 g) unsalted butter, cut into cubes and cool, but not cold 1 tablespoon + 1 teaspoon (20 ml) pure vanilla extract pinch of salt Instructions Wipe the bowl of an electric mixer with paper towel and lemon juice, to remove any trace of grease. Add egg whites and sugar, and simmer over a pot of water (not boiling), whisking constantly but gently, until temperature reaches 160°F, or if you don't have a candy thermometer, until the sugar has completely dissolved and the egg whites are hot. With whisk attachment of mixer, begin to whip until the meringue is thick, glossy, and the bottom of the bowl feels neutral to the touch (this can take up to 10 minutes or so). *Don't begin adding butter until the bottom of the bowl feels neutral, and not warm. Switch over to paddle attachment and, with mixer on low speed, add butter cubes, one at a time, until incorporated, and mix until it has reached a silky smooth texture (if curdles, keep mixing and it will come back to smooth). *If mixture is too runny, refrigerate for about 15 minutes and continue mixing with paddle attachment until it comes together. Add vanilla and salt, continuing to beat on low speed until well combined. Add additional flavours, purees, as desired. Notes: *Keep in airtight container in refrigerator for up to one week, leaving out at room temperature when needed, rewhipping in mixer for 5 minutes. **Can freeze for up to 6-8 weeks. To thaw, place on counter overnight, and rewhip for 5 minutes with paddle attachment in an electric mixer. ***If buttercream still doesn't have its satiny finish after rewhipping, microwave 1/3 of the buttercream for approximately 10 seconds and add to remaining buttercream in mixer bowl, beating for a few moments to incorporate. Notes on a few Variations: Chocolate Buttercream: Add 300 g (1 1/2 cups before melting) melted bittersweet high quality chocolate (the best you can get–I use Callebaut) for every 5 cups of vanilla Swiss Meringue Buttercream and beat until incorporated. Strawberry Buttercream (or any other berry version): Add fruit puree to taste (approximately 1/2 cup for 5 cups of SMB). Vanilla Bean Buttercream: Add 1 tablespoon of vanilla bean paste OR 1 vanilla bean, scraped for every 5 cups of SMB, and beat until incorporated. Lemon Buttercream: Eliminate vanilla extract and add 1 teaspoon of pure lemon extract for every 5 cups of SMB, or to taste, and beat until incorporated. You can also add liqueurs and other flavourings, as well as any food gel colours to achieve any desired colour.
