Buy RS3 2/3 cake
The 2/3 cake is a food item in RuneScape 3. It is what a whole cake becomes after one bite is taken. It has two bites left, and each bite heals 333 life points. That means one 2/3 cake can restore up to 666 life points in total. After one more bite, it becomes a slice of cake.
Cake is a low cost food with light healing. It is not a strong pick for combat or player-killing, but it works well as a snack while training skills like Thieving or Agility. The 2/3 cake weighs 0.2 kg, so it is easy to carry in your inventory.
Players cannot buy or cook a cake in this partial form. A whole cake must be made with level 40 Cooking or stolen from a bakery stall, then eaten once to become a 2/3 cake. The 2/3 cake itself can be traded on the Grand Exchange, so it is a simple way to stock up on cheap healing food without making cakes from scratch.
