Whether you are celebrating a child's third birthday, a third wedding anniversary or the anniversary of a business, consider baking a cake shaped like the number three. While you can purchase a cake pan shaped like a three online or in speciality baking shops, you can also cut cakes yourself to create the number. Making a number three cake is not as difficult as it may seem.
Cover your two round cakes and place them in the refrigerator for about half an hour. This will help the cakes become firm and less likely to crumble when you cut and shape them.
Remove the cakes from the refrigerator and place them on a clean, flat surface.
Carve a shape that looks like the letter C out of the first cake. Use the outer curve of the cake as the outer curve of the letter. Use your serrated knife to score the cake before cutting into it to make sure you are happy with the design of the number. Use the serrated knife to carefully remove the inner section of the cake, leaving the C shape.
Repeat the step above with the second cake, leaving you with two C shapes.
Take a large cake platter and turn each cake upside down. Place the cakes on the cake platter, one above the other, creating the number three. If you need to, cut a few inches off of the area where the cakes meet, at the centre of the number, to make it shorter and to help the cakes come together better.
Frost the two cakes. Use a thicker layer of frosting on the area where the cakes meet so that the cut borders do not show.
Decorate the cake with assorted cake decorations, such as candies and sprinkles, so that it fits the occasion.
