Hamburger Cake

A hyper-realistic sculpted cake of a classic cheeseburger and fries — thick dark brown beef patty with bright yellow melted cheese and red ketchup, layered between pale green lettuce and red tomato slice, topped with a golden-brown sesame seed bun, all on a platter piled with golden-brown french fries.

Instructions

  • Bake a cake in the flavor of your choice. Carve four separate layers: the bottom area (for fries), the bottom bun, the burger patty, and the top bun. Cover all layers in chocolate ganache and refrigerate for 2 hours.
    A hand spreads chocolate ganache over a carved cake layer with an offset spatula.
  • Roll out beige fondant. Cover the bottom bun area. Trim excess and shape.
    Hands cover the bottom bun cake layer with rolled beige fondant.
  • Push five cake straws into the bottom bun through to the cake plate.

  • Brush the bottom bun layer with edible color.

  • Roll out yellow fondant very thin. Trim to look like a slice of cheese. Stack on the burger layer.
    Hands place a thin yellow fondant cheese slice onto the burger patty.
  • Roll out red fondant thickly for a tomato slice. Cut with a round cookie cutter. Carve out and shape the tomato interior with a cake tool. Detail with white edible paint.

Notes

• Fondant is a rolled icing made from sugar, water, corn syrup, and glycerin — it rolls out like dough, unlike buttercream.
• Cake straws provide crucial structural support, as cake is heavy and can be unstable.
• This is a forgiving project — unlike a wedding cake, your hamburger doesn't have to look perfect.
