Inspired by the famous Tokyo Banana, our homemade version uses a light vanilla sponge, with a delicious banana custard cream. This banana custard cream uses real bananas to get its consistency, and pairs amazingly with the light sponge for a wonderful treat — if you want to learn to make your own, this is the kit for you.

Every one of our recipes was created to use medium-sized eggs, as that is easily found in the supermarket. To make sure your eggs are the right-sized, get eggs that weigh 55g with shell. To determine that, follow the steps below when buying your next carton:

  • Check the label for the total weight of all the eggs.
  • Take that number and divide it by the total number of eggs in the carton
  • The answer should be ~55g.

Example: 

Carton of 10 eggs > Total weight = 550g > 550/10 = 55g
