Description

Create your own charming, small-batch Bento cakes featuring a light, airy Genoise sponge and a nostalgic Oreo-infused buttercream. These miniature delights are perfect for thoughtful gifting or celebrating life’s quiet, meaningful moments with a touch of sweetness.


Ingredients

  • 4 Large Eggs
  • 132g Granulated Sugar
  • 152g All-Purpose Flour
  • 1 Tablespoon Liquid Vanilla
  • Funcakes Buttercream Mix
  • Oreo Flavoring
  • 300g Butter (pommade consistency)


Instructions

  1. Whisk eggs and sugar together for 5 to 8 minutes until the mixture triples in volume and becomes thick and pale, then stir in the vanilla.
  2. Gently sift the flour over the mixture in three additions, folding carefully after each to maintain the air bubbles.
  3. Bake the batter in prepared pans at 350°F (180°C) for 12 to 15 minutes until golden and springy.
  4. Prepare the buttercream base with water, then beat in the softened butter and Oreo flavoring until light and fluffy.
  5. Cut the cooled cake into 4-inch circles and assemble with layers of frosting, finishing with a smooth outer coat.

Notes

For the smoothest finish, apply a thin crumb coat to your cake and chill it briefly before adding the final layer of Oreo buttercream. Ensure your sponge is completely cool before cutting or frosting to prevent the delicate layers from tearing or the butter from melting.
