KOREAN LUNCHBOX CAKE INGREDIENTS

VANILLA EXTRACT

Vanilla extract adds a delightful flavor to your Korean lunchbox cake. This can be replaced with vanilla bean paste.

FLOUR

To have softer and fluffier lunchbox cakes, it is recommended to use cake flour as it has less gluten and is more fine that its counterparts. But if the cake flour is not available, you can still use the all purpose flour.

BAKING SODA

This ingredient serves as a raising agent in the cake batter. Make sure not substitute this ingredient with any homemade raising agents when preparing this lunch box cake recipe

SUGAR

Powdered sugar gives a sweet taste to your cute little cakes. Granulated sugar is the ideal option, but brown sugar can also be used if the former is not available.

EGGS

Eggs create structure and stability within a cake batter. They add moisture to your mini cake. For this Korean lunch box recipe, you’ll need large eggs. Make sure to leave them out at room temperature 2 hours in advance.

VEGETABLE OIL

To make your mini cake softer and extremely moist, use a non-flavored and odorless vegetable oil. This liquid gives the sensation of moistness far more reliably than its butter-based counterparts. 

You can opt for sunflower oil or canola oil.

MILK

Milk is one of the liquid ingredients that activates other cake batter ingredients such as baking soda or baking powder. It makes the texture of the batter lighter and stronger due to its protein and lactic acids contents.

You can use any kind of milk such as plant-based or lactose free milk.

SALT

The salt will enhance the flavor of the other ingredients in your lunchbox cakes. It provides a balance to the cake batters’ sweetness. For this recipe, it is ideal to use an extra fine salt.

INGREDIENTS FOR THE LUNCHBOX CAKE FILLING OR FROSTING

Fillings in between cake layers hold the layers together, give your cake flavor, and add height. Here are the ingredient you need to make the cake filling:

SUGAR

This ingredient makes your filling soft and moist. To have the smoothest frosting, use powdered sugar.

HEAVY WHIPPING CREAM

Heaving whipping cream gives a lighter consistency and lighter texture of the filling. Make sure to use a properly chilled whipping cream before making a filling and frosting for your bento cake.

CREAM CHEESE

The cream cheese helps keep bento cake filling moist and dense. It prevents the filling from drying out. 

VANILLA EXTRACT

The vanilla extract chemically adds more flavor to the filling and brings out the flavors of the fillings’ other ingredients.

For an exceptional and natural filling flavor, use vanilla bean paste.

JAM

This ingredient is optional. However, if you are up for extra flavor, you can use fruit jam with fruit chunks to add texture and more flavor to the entire cake. You can use raspberry, blackberry, blueberry, or strawberry jam.
