Japanese cakes and snacks to buy online: how to choose without making a mistake

Fancy some Japanese cakes and snacks, but not sure which one is right for you? Online, many packets look appealing, yet the differences in flavour, storage, portion size and ingredients can be significant. A soft cake might need to be refrigerated, for example, while a similar baumkuchen is best kept at room temperature.

With this practical buying guide, you can compare Japanese castella, Japanese baumkuchen, dorayaki and other Asian sweet treats on the points that really matter in a British household.

Three common pitfalls with Japanese snacks

1. Relying only on the flavour name

“Strawberry”, “milk” or “chocolate” on the packet doesn’t automatically tell you how much of that ingredient is actually present. Always check the ingredients list. According to the product information, the Sakuraseika Amaou Strawberry Castella contains strawberry purée, among other things, but also egg, wheat flour, honey and vegetable oil. If you’re expecting a pronounced fruit flavour, it’s worth looking at the full list of ingredients.

2. Overlooking storage requirements

Not every cake is suitable for the cupboard. According to the product information, the Amaou Strawberry Castella and Sakuraseika Hokkaido Milk Cake need to be kept refrigerated. Other products, such as various baumkuchen and dorayaki, require a cool, dry place. So always check the label and the best-before date after you receive your order.

3. Ignoring allergens and portions

Many Japanese desserts contain wheat, egg, milk or soya. Some packets also mention possible traces of peanuts, nuts or sesame. Individually wrapped portions are handy for taking with you and for portion control, but the weight varies a lot: from 52 grams per cake to a box containing several pieces. So don’t just compare the price per packet, but also the weight per portion.

Which specifications should you check?

Texture and type of cake

  • Japanese castella: a soft, airy cake with a fine crumb. The strawberry and peach varieties are suitable as a snack, dessert or with tea.
  • Japanese baumkuchen: recognisable by its thin layers and often a soft, moist texture. Available in flavours including banana, milk, plain and chocolate.
  • Japanese dorayaki: two soft, round cake halves with a filling, often red bean paste. The mini version is practical for on the go.
  • Milk cake: generally a soft cake with a milky flavour. Pay close attention to milk ingredients and the recommended storage.

The phrase “no artificial colours or preservatives” should only be judged based on the product information and ingredients list. It doesn’t automatically say anything about nutritional value or suitability for every dietary preference.

Packaging and when to use it

Individually wrapped cakes are practical for work, school, visitors or a picnic. A packet with several pieces is better suited to a family or a tea-time with guests. For a gift, a box of six, such as a halal baumkuchen, can be more convenient than individual portions.

For halal products, check that the packaging actually shows a certification or a clear indication. For Taiyo products, this is stated in the product name as “Halal Certified”; check the current packaging if this is a deciding factor for your purchase.

Comparing nutritional information

The nutritional values in the product information are usually given per 100 grams. This makes comparison possible, but a portion may be smaller. For example, the Atom Japanese Banana Baum Cake contains 324 kcal per 80-gram portion, according to the stated table. So look at:

  1. the weight of one cake;
  2. the amount of sugar and fat per 100 grams;
  3. the actual portion size;
  4. allergens and any trace warnings.

Frequently asked questions about Japanese cakes and snacks

What is the difference between castella and baumkuchen?

Castella is usually a soft, airy sponge cake. Baumkuchen is recognisable by its structure of thin layers, often in a ring shape. The texture of baumkuchen is generally more compact and layered.

How should I store Japanese cakes after receiving them?

Always follow the packaging. Some varieties need to be refrigerated, such as certain castella and milk cakes. Other cakes will keep unopened in a cool, dry place. After opening, it’s important to seal them well to prevent drying out and loss of quality.

Are Japanese desserts suitable for people with an allergy?

That varies from product to product. In this category, wheat, egg, milk and soya are common. Read the ingredients and allergen information before purchasing. If you have a serious allergy, it’s also wise to check the warning for possible traces and, if in doubt, consult the manufacturer or seller.
