Vegan Korean Bento Cake

Vegan Korean Bento Cake

This Vegan Korean Bento Cake (also known as a lunchbox cake) is a miniature version of a regular sponge cake, filled with a homemade strawberry jam and topped with vegan white chocolate buttercream. Get the recipe below.

What are bento cakes?

Korean bento cakes, also known as lunchbox cakes, are adorable mini cakes designed to be enough to serve 1 or 2 people. They are usually between 2 and 4 inches. For my vegan bento cake I use a tin that is 4 inches wide.

They are often decorated with bright, pastel colours, sometimes with floral or fruit designs. Often they are round in shape but they can be heart shaped too – perfect for a Valentines Day gift!

As the name suggests they originated from South Korea.

How do you make a vegan Korean bento cake?

Baking a bento or lunchbox cake is the same as making a regular cake just miniature.

Vegan sponge cake

Making vegan sponge cakes doesn’t have to be hard. In fact making egg-free sponge cakes doesn’t require any weird and wonderful ingredients – just your store cupboard staples. This cake gets its lift from baking powder instead of eggs.

To make the sponge moist we mimic buttermilk by mixing yogurt and apple cider vinegar along with the other wet ingredients (oil, sugar and plant milk). This makes for a really tender crumb.

Vegan strawberry jam

The jam you buy in the supermarket should be vegan but just double check to be safe.

Alternatively make your own jam! Get my strawberry jam recipe here.

Vegan buttercream

Much like the cake, making dairy free buttercream is easy too! We’re so lucky that we have amazing vegan dairy substitutes these days. To make my butter cream I just sub butter for vegan butter…that simple. No other adjustments needed!

But the key to the best buttercream is beating it for longer than you think. You want it to be super pale, creamy and fluffy, not at all grainy.

What specialist items will I need?

To make this Vegan Korean Bento Cake you will need three things you might not already have:

  • A 4 inch cake tin or silicone mould
  • A 6 inch lunchbox container
  • Sandwich paper (though baking paper would also work)

What if I can’t find a 4 inch cake tin?

Your other option is to bake the sponge in a sheet pan then use a 4 inch cookie cutter to cut out the layers. You can find instructions on how to do that in my other miniature cake recipe.
