Please note: this chocolate cake recipe makes1 batch. You’ll need two batches of chocolate cake to make this 6 layered cake.All other ingredients in the recipe are measured up to make the full 6 layer cake.Preheat a fan-forced oven to 140°C / 280°F or 160°C /320°F for a conventional oven. Spray three 8” cake tins with oil spray and line the bottom with baking paper. Add the flour, sugar, cocoa powder, bicarb soda and salt to a large mixing bowl and mix together using a hand mixer to combine.
Next add the softened butter and mix on low speed until mixture reaches a crumbly sand like texture.
Add the eggs and milk and mix on low speed until no dry ingredients are showing. Scrape down the bowl and mix for another20 seconds.
Fill three 8” cake tins with batter. I find using an ice cream scooper to help me do this makes it easy to distribute the batter evenly so that everything bakes at the same time.
Bake for 50-60 min or until a toothpick inserted comes out clean. If the pick comes out with wet batter, bake for a further 10 min at a time until baked fully. Allow the tins to cool for 2 min and then carefully flip the cake tins over on to a cooling rack to cool completely before using. Chilling your cakes overnight before decorating means they’ll be easier to trim and decorate. So I bake my cakes the day before I trim them.
To trim your chilled cake use a cake leveler or large serrated knife to carefully trim the first layer of cake by trimming it in half. Then trim the crust off the second layer so that you end up with two layers from each baked cake. When trimming make sure you aim to get both layers of cake the same height. Keep that in mind when trimming the first layer so the next layer will still be the same height as the first when trimming the crust off. Once you’re done trimming your three baked cakes you should end up with 6 layers of cake altogether.
To prepare crumb coat, add a dab of chocolateSwiss meringue buttercream frosting onto an 10” cake board or serving plate. Add the first layer of cake. Pipe a ring of frosting around the first layer and fill the center of the cake with more frosting. Use a small offset spatula to spread around a little before adding some chopped mint slice cookies. Add the second layer of cake and repeat with the remaining layers. Add more frosting around and top of the cake. Use a your small spatula to smoothen out the top and bottom of the cake before using a cake scraper (otherwise known as a bench scraper) to smoothen out the frosting. Get it as neat as you can. This should just be a neat thin layer of frosting which is aimed at trapping any cake crumbs so that random bits of cake crumbs don’t show up on the outside of the cake. Chill for 2 hours or overnight.
Add a fresh layer of frosting using a small offset spatula. Use a cake scraper to smoothen out the frosting around the sides. Then smoothen out the top using the cake scraper.
Stick the chocolate bark all around the cake.
