TopicHow many does a 3/4 sheet cake feed.
PostedThu, Sep 12th 2019 22:22 PM
It takes two 18-ounce boxes of cake mix to make a half sheet cake, measuring approximately 12-by-18 inches. A half sheet cake provides 36 to 108 servings, depending on how it is sliced. Commercially prepared half sheet cakes are often made by assembling two 9-by-13-inch cakes on a cake board.
During baking, check the cake at least a couple of times to determine if it is finished, taking into account a shorter baking time than a standard recipe. For easier handling when making layer cakes, place your baked sheet cake in the freezer or at least the fridge wrapped in plastic.
