The Cake Core speaks in a slow, monotonous voice, and spends its time reciting a cake recipe, which often has or potentially ingredients. As it speaks, it will roll lazily around, seemingly entranced in recipe recitation.
The Cake Core is voiced by Ellen McLain.
The recipe he gives in LEGO Dimensions consists of "fish-shaped solid waste, a single banana, and a cup of lemonade." These are all included in the actual cake recipe.
- The Cake Core has three dots on each side, as it is the third core to be incinerated. This pattern is seen on all cores from Portal.
