9. Triple-Layer Protein Cake

If you want something dramatic, go for a triple-layer cake:

  • Bottom layer: tuna
  • Middle layer: chicken
  • Top layer: salmon

Stack them neatly using small round molds. Spread a thin layer of mashed potato between each for stability. Decorate with treat crumbs around the sides.

This layered look makes it feel like a real celebration cake — impressive and totally photo-worthy.
