Sharp edges on cakes are the recent trend. And yet, getting sharp edges on buttercream cakes can be a bit more challenging than with ganache. But, these two simple and easy methods will surprise you and give you the confidence you need.
Bake your favorite cake. When it's done, let it cool in the pan for 10 minutes. Then, invert it onto a cooling rack and let it cool completely before decorating.
Prepare simple syrup – cool completely before using.
Once cooled, cut the domes off the cake layers using a serrated knife. Brush each layer with the cooled simple syrup.
Fill the cake - Pipe a buttercream dam on the cake layer (see video). Top with a big dollop of the coconut cream filling. Then, spread evenly with an offset spatula or spoon within the piped buttercream dam/edge.
Next, top the second cake layer, followed by the buttercream dam and filling. Then, place the last cake layer on top.
Place the cake in the fridge to chill for 10 to 15 minutes.
Crumb coat - Spread more buttercream around and on top of the cake. (see video). Chill the cake for another 15 to 30 minutes.
Sharp edges
Once the crumb coat is chilled, add a big dollop of frosting on the top of the cake. Smooth around. Let it chill in the fridge for at least an hour to firm up.
Next, frost the sides of your cake, leaving a large lip of frosting on the top, as I have shown in the progress pictures. Smooth the sides as best you can. Then, chill the cake for an hour or more.
Next, use a sharp knife and hot water to cut the extra lip of frosting you created on the top flush with the top of the cake. This should give you a sharp edge.
Final touches - If necessary, add a thin layer of frosting to fill in any air pockets or uneven spaces.
Once the frosting is set, ensure you have a level cake. Use a bench scraper dipped in hot water to smooth the sides of the cake.
