TO ASSEMBLE AND DECORATE THE CAKE
- If cakes are domed on top, even out with a knife or a cake leveler (Cold cakes work better here).
- Add a little bit of frosting on a cake board and place the first layer of cake over it. Use your hands to press down over the cake.
- Using a pastry bag, pipe the buttercream around the top of the first layer and smooth using a spatula, make a second layer of buttercream but only around the edge of the cake, so you make a “wall” around the edge. Make sure to do a thick border, otherwise the filling could spill out from the cake.
- Add some cooled jam into the gap and smooth using a spoon. Place the next cake layer on top.
- Spread some buttercream all over the cake, just for the crumb coat and then take off any excess with the spatula and place the cake inside the refrigerator about 30 minutes.
- Bring the cake back from the chiller and start covering with buttercream using an cake smoother. Begin frosting the cake and smoothing slowly. Be patient. Pay attention to get smooth surfaces. Leave an edge rising up around the top of the cake as shown in the pictures above.
- You will need 1 printed A4 sugar sheet to cover the cake. I’ve got the license of the image from here.
- Cut the sheet in two halves along the long side. Place each half around the cake directly on the frosting rubbing with your fingers to achieve a smooth surface. Cut out any excess of the sugar sheet.
- Decorate with some berries and icing sugar.
- Enjoy.
Tips using sugar sheets
- Applying the sheets on American buttercream frosting or ganache is highly recommended to avoid condensation.
- Once the cake is covered with the sugar sheet it should not be storage back in the fridge, as the humidity could create air bubbles or break the paper.
- keep the decorated cake in a fresh, cool and dry place for optimum results.
- The berries should not be in direct contact with the sugar sheet.
- If the sugar sheets is hard to release from the acetate film, place it into the freezer for 30 seconds and try to peel it off again.
- Avoid condensation.
