Cucumber cake is a type of cake that is made with cucumbers. It is a unique and tasty treat since you don't usually think of putting cucumbers in a cake. The cake is made with cucumber purée, sugar, and some other ingredients like flour, butter and eggs. The purée is made by blending the cucumbers and then straining the juice from them. The purée is then mixed with the sugar and other ingredients to make a batter, which is poured into a cake pan and baked. The result is a moist and sweet cake with a crunchy texture and a hint of cucumber flavor. It's a great snack cake to serve at parties or to enjoy as a dessert.
