Making a Brain cake is fun, cheap and great for Halloween parties or get-togethers. This is a basic instructable to show you how to make the details for this cake, the size and shape depends on your preferences. You can do similar designs for cupcakes or even flat cakes depending on what best fits your needs. This cake is made from two 8 inch pan cakes that were cut and assembled together to make a more realistic brain cake. The gore is also optional, although it does make the cake look more grusome and realistic.
