For the Sponge Cake

- 1 tablespoon cornstarch
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 2 tablespoons milk warm
- 2 tablespoons vegetable oil
For the Mango Cream Filling
- 1½ cups heavy whipping cream chilled
- 3 tablespoons powdered sugar
- 1 teaspoon vanilla extract
- 1½ cups diced fresh mango Ataulfo or Champagne mangoes work great

Step 1: Make the Sponge Cake
Preheat your oven to 350°F (175°C). Line your cake pan or sheet pan with parchment paper.
In a mixing bowl, beat the eggs and sugar using an electric mixer on high speed until light, pale, and tripled in volume—about 8–10 minutes.
Gently fold in the sifted flour, cornstarch, and salt using a rubber spatula. Take your time here—fold just until combined.
Mix the milk, vanilla, and oil in a small bowl, then add a small scoop of the batter into this liquid mix. Stir gently, then fold this mixture back into the main batter.
Pour into your prepared pan and tap gently to remove air bubbles. Bake for 18–20 minutes until golden and springy.
Let it cool completely. If using a sheet pan, use a 3–4 inch round cutter to make your mini cake layers.
Step 2: Make the Mango Whipped Cream
In a chilled bowl, beat heavy cream, powdered sugar, and vanilla until stiff peaks form. Be careful not to over-whip.
Gently fold in diced mango, reserving some for layering or decorating.
Step 3: Assemble Your Korean Lunch Box Cake
If you baked a full cake, slice it evenly into two or three layers using a serrated knife. If you used a sheet pan, stack cutouts for individual layers.
Place one sponge layer on your mini cake board or bento box lid. Add a generous scoop of mango cream and spread evenly.
Top with another sponge layer. Repeat if doing three layers.
Use an offset spatula to frost the entire cake with mango cream. Chill briefly (10–15 minutes) if cream is soft.
Decorate with thin mango slices, rosettes, or piped cream swirls. Add sprinkles for celebration flair.
Tip: These also make beautiful mini cakes birthday gifts—pop them into individual bento boxes for a personalized treat.

FAQs
1. Can I use boxed cake mix instead of making the sponge from scratch?
Absolutely. A light vanilla or white cake from box cake recipes can work well. Just make sure to bake it in a sheet pan for easy cutting.
2. What type of mango is best for this cake?
Ataulfo or Champagne mangoes are ideal—they’re sweet, non-fibrous, and easy to dice. Avoid overly ripe mangoes as they can make the cream soggy.
3. Can I use store-bought whipped topping?
Yes, if you're short on time. However, fresh whipped cream offers better flavor and texture.
4. Are these cakes freezer-friendly?
They’re best fresh, but you can freeze the sponge layers ahead of time. Assemble with cream and mango only before serving.
5. Is this suitable as a Christmas morning breakfast treat?
While it’s more of a dessert, this mango cake is light enough to be enjoyed in the morning—especially if you’re planning a festive brunch spread with a mix of Korean lunchbox cakes and savory bites.
