Fair cake-cutting: Fair cake-cutting is a kind of fair division problem.  The problem involves a "heterogeneous" resource, such as a cake with different toppings, that is assumed to be "divisible" – it is possible to cut arbitrarily small pieces of it without destroying their value.  The resource has to be divided among several partners who have different preferences over different parts of the cake, i.e., some people prefer the chocolate toppings, some prefer the cherries, some just want as large a piece as possible.  The division should be subjectively fair, in that each person should receive a piece that he or she believes to be a fair share.

Heavy cake: Heavy cake or Hevva cake (Cornish: Hevva ) is a cake made from flour, lard, butter, milk, sugar and raisins that originated in Cornwall.

Wedding cake: A wedding cake is the traditional cake served at wedding receptions following dinner.  In some parts of England, the wedding cake is served at a wedding breakfast; the 'wedding breakfast' does not mean the meal will be held in the morning, but at a time following the ceremony on the same day.  In modern Western culture, the cake is usually on display and served to guests at the reception.  Traditionally, wedding cakes were made to bring good luck to all guests and the couple.  Modernly however, they are more of a centerpiece to the wedding and are not always even served to the guests.  Some cakes are built with only a single edible tier for the bride and groom to share, but this is rare since the cost difference between fake and real tiers is minimal.

Tres leches cake: A tres leches cake (Spanish: "pastel de tres leches" or "torta de tres leches"), also known as pan tres leches ("three milks bread"), is a sponge cake—in some recipes, a butter cake—soaked in three kinds of milk: evaporated milk, condensed milk, and heavy cream.

Envy-free cake-cutting: An envy-free cake-cutting is a kind of fair cake-cutting.  It is a division of a heterogeneous resource ("cake") that satisfies the envy-free criterion, namely, that every partner feels that their allocated share is at least as good as any other share, according to their own subjective valuation.
