The term "icing cake" refers to the practice of covering a cake with a layer of sweet, creamy frosting. The process is widely used in baking and is an excellent way to enhance the flavor and texture of a cake. However, if you're looking to change things up a bit, there are plenty of antonyms for this practice. For instance, instead of using a thick layer of frosting, you could consider skipping the frosting altogether and instead adding fresh fruit, edible flowers, or a light dusting of powdered sugar. Alternatively, you might choose to drizzle a thin glaze of sweet syrup or melted chocolate over the top of the cake. The possibilities are endless!
