2. If you’re making cake for a stacked, tiered wedding cake, put cake upside down on a cake board of same size, so the bottom becomes the top. A cake turntable will help give a professional finish. Otherwise, put the cake straight on to a cake stand or serving plate.
3. To stop crumbs being visible in the icing on the finished cake, first ice it with a crumb coat – a thin layer of icing that will seal in any stray crumbs. Spoon a third of buttercream into a separate bowl. This will stop crumbs tainting rest of icing. Dollop a large blob of icing on to the top of the cake and spread evenly over top, turning turntable all time. Once the top is covered, lightly hold the edge of the palette knife against the icing, turning the turntable slowly to scrape away a thin layer of icing and smooth the top flat. Scrape excess icing back into bowl and repeat process until top is flat.
4. Spread icing around the sides of the cake with the palette knife. Keep adding icing until sides are completely covered, with no gaps. Hold the edge of the palette knife against the side of the cake. Slowly turn the cake so that the knife takes off excess icing, without exposing the cake. Scrape excess icing back into bowl and continue until sides are smooth and even. Discard any remaining crumb coat icing. Chill cake for 2hr.
5. Repeat entire process with the remaining buttercream to add a second layer of icing, for a super-smooth finish.
