DIRECTIONS

Coconut Cake
1. Preheat the oven to 350°F. Butter 2 x 6 inch pans, line them with rounds of parchment paper, then dust with flour and tap out the excess.
2. Beat the butter and sugar with a mixer (a hand mixer or stand mixer will work perfectly) until light and fluffy, 3-5 minutes.
3. Crack the eggs into a small bowl then add to the mixing bowl one at a time while mixing on low speed. Scrape the sides of the bowl down and mix until incorporated.
4. Stir the vanilla extract and almond extract into the milk in a small bowl. Sift the flour, baking powder, baking soda and salt together in another bowl, then alternate adding the wet and dry ingredients to the butter mixture, beginning and ending with the dry ingredients. Mix just until combined after each addition. Add the coconut and mix by hand until evenly distributed.
5. Pour the batter into the pans, smoothing with the back of a spoon. Bake for 20 minutes, rotate the pans, then bake for an additional 3-5 minutes or until a toothpick inserted in the center of the cake comes out clean. Place on cooling racks for 10 minutes then run a knife around the edges of the cake to loosen them from the pans and turn out onto the racks to come to room temperature before icing. Can be made 1 day ahead, wrap tightly in plastic wrap and store at room temperature.
White Chocolate Buttercream
1. Using either a double boiler or a microwave, gently melt the white chocolate and set it aside to cool.
2. In a medium heavy-bottom saucepan, whisk the sugar and flour together. Add the milk and cream and cook over low to medium heat, whisking occasionally until the mixture begins to thicken then whisking constantly until it comes to a boil, about 20 minutes.
3. Transfer the mixture to the bowl of an electric mixer fitted with the paddle attachment. Beat on high speed until cool. Reduce the speed to low and add the butter a piece at a time; mix until thoroughly incorporated. Increase the speed to medium-high and beat until the frosting is light and fluffy.
4. Check the white chocolate to be sure it is still smooth (if your kitchen is freezing like mine you may have to warm it a little until it is smooth again) Add the vanilla extract, vanilla bean paste, salt and melted white chocolate and continue mixing until combined.
5. If the frosting is too soft, put the bowl in the refrigerator to chill slightly, then beat again until it is a spreadable consistency. If the frosting is too firm or if you find the white chocolate has given it a grainy texture, set the bowl over a pot of simmering water and beat with a wooden spoon until it is the proper consistency. Beat with the mixer until smooth. Can be made 3 days in advance, bring to room temperature and rewhip before using.
Lime and Matcha Curd
1. Bring about an inch of water in a large saucepan to boil, then reduce to low and simmer. Combine the lime juice, egg yolks, whole egg and sugar in a metal bowl that fits snugly into your saucepan. The bottom of the bowl should be above the water, not in it to prevent cooking the eggs.
2. Gently whisk until mixture reaches 170°F or until it has thickened and coats the back of a spoon, about 10 minutes. Remove from heat.
3. Stir in butter pieces until combined. Sift Matcha powder with a very fine sieve into the curd and stir well, then strain the mixture and stir in the lime zest. Allow the curd to cool then cover with a layer of plastic wrap directly on the surface of the curd to keep a skin from forming.
4. Curd will keep in the fridge for up to 5 days or frozen (in a ziplock or container) for 3 months.
Lime and Matcha Shortbread Crumbles
1. Place the butter and zest in the bowl of a stand mixer fitted with the paddle attachment. Cream on medium-low speed until smooth, about 3 minutes.
2. Add the sugar and salt and mix on medium-low speed for about 2 minutes or until fluffy. Scrape down the sides and bottom of the bowl.
3. Add the vanilla bean paste and mix on low speed for about 30 seconds to distribute evenly. Add the flour and Matcha in 2 additions, mixing on low speed for 15 to 30 seconds after each, or until just combined. Scrape the bottom of the bowl to incorporate any flour that may have settled there.
4. Preheat oven to 325°F. Line a cookie sheet with parchment paper and scatter crumble-size bits of the dough onto the cookie sheet. Bake for 5 minutes, then use a spatula to turn the crumbles so they don't brown on the bottoms. Bake for about 3 more minutes or until done, then place the pan on a cooling rack until the crumbles are at room temperature.
5. Break apart as needed and use to decorate the top of the cake. I used about ⅓ of the dough to make the crumbles (to save the chilling time) and made use of the rest to make cookies. If you're assembling the cake just before serving you could also sprinkle some crumbles between the cake layers for a little crunch.
