Ingredients

Scale
  • For the Cake:
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon baking powder
  • 1/4 cup granulated sugar
  • 1 egg
  • 2 tablespoons milk
  • 1 tablespoon vegetable oil
  • 1/4 teaspoon vanilla extract
  • For the Frosting:
  • 1/2 cup unsalted butter, softened
  • 2 cups powdered sugar
  • 2–3 tablespoons milk
  • 1/2 teaspoon vanilla extract
  • Gel food coloring (optional)
  • For Decoration:
  • Sprinkles, edible glitter, chocolate ganache, or any desired toppings

Instructions

  1. Baking the Cake
  2. Preheat your oven to 350Β°F (175Β°C). Grease and flour your 4-inch cake pan.
  3. In a mixing bowl, whisk together the flour and baking powder.
  4. In a separate bowl, beat the sugar, egg, milk, oil, and vanilla extract until well combined.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
  6. Pour the batter into the prepared cake pan and bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean.
  7. Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
  8. Preparing the Frosting
  9. In a large mixing bowl, beat the softened butter until smooth and creamy.
  10. Gradually add the powdered sugar, beating on low speed until combined.
  11. Add the milk and vanilla extract, then increase the speed and beat until the frosting is light and fluffy.
  12. If desired, add a small amount of gel food coloring to achieve your desired shade.
  13. Decorating the Bento Cake
  14. Once the cake is completely cool, use a serrated knife to level the top if necessary.
  15. Apply a generous layer of frosting over the entire cake. Smooth the frosting with a spatula or knife.
  16. Get creative with your decorations! Use sprinkles, edible glitter, or chocolate ganache to add visual appeal. You can use piping bags and tips to create intricate designs or write a personalized message.
  17. Final Touches
  18. Carefully place the decorated bento cake into a Japanese lunchbox or small container.
  19. Add a small spoon or fork for easy enjoyment.
  20. Refrigerate for at least 30 minutes to allow the frosting to set before serving.

Notes

  • Don’t Overmix: Overmixing the cake batter can result in a tough cake. Mix until just combined.
  • Cool Completely: Ensure the cake is completely cool before frosting to prevent the frosting from melting.
  • Use Quality Ingredients: Using high-quality ingredients will enhance the flavor of your mini cake.
  • Get Creative: Don’t be afraid to experiment with different flavors and decorations to create a unique cute cake.
  • Practice Piping: If you’re using piping bags for decoration, practice your designs on a piece of parchment paper first.
