Cream butter and icing sugar using an electric whisk until smooth and well combined.
Add egg whites and beat thoroughly until fully incorporated.
Stir in flour gently until just combined. For chocolate pattern, replace part of the flour with cocoa powder.
Divide mixture into bowls and colour as desired.
Cut baking paper to fit your tray.
Pipe or spread decorative patterns onto the baking paper. The pattern can be traced over a picture or template. Use small icing cones with a tiny hole cut out. I generally pipe pattern on half side of the rectangular sheet as shown in picture. The plain side of the sponge is used as the second layer to form the sandwich with cream filled between the two layers.
When piping the pattern, use layering method, like for example pipe eye first, and the fine details which are then covered by the larger pattern.
Freeze the patterned sheet for 5 to 8 minutes or until firm.
Preheat oven to 200°C / 392°F.
Keep frozen pattern tray ready.
Separate egg whites and yolks.
Add ¼ cup sugar to yolks.
Add remaining ¼ cup sugar and cream of tartar to egg whites.
Whip egg whites until firm peaks form.
Using the same beaters, whip yolks with sugar until pale and thick.
Melt butter and keep it slightly warm.
Fold whipped egg whites into the yolk mixture in 3 batches.
Add half of the flour and butter and fold gently.
Add the remaining flour and butter and fold until no dry streaks remain. The batter should stay light and airy.
Pour sponge batter gently over the frozen pattern sheet.
Spread carefully to tray edges using a flat spatula.
Tap the tray lightly on the table to release air bubbles.
Bake in the centre of the oven for 7 minutes only.
Trim edges immediately while the cake is still hot using a serrated knife.
Cover with baking paper, place a chopping board over it, and flip.
Peel off the baking paper while still hot.
Boil sugar and water for the syrup, cool slightly, and add vanilla.
Brush the syrup lightly over the sponge once cooled.
Neatly cut the baked sponge into two halves. Spread whipped cream frosting over the plain half and place patterned side carefully over it. You can even use a thin layer of jam if you like. Your Ritu style Pattern Deco cake is ready!
