Everyone will be sure to choose the treat over the trick with this cake!

Make cake-shaping clay. Press the clay into the bottom of a 10-inch round pan, forming a layer of clay 3/4-inch deep. Remove a circle of the clay from the center of the pan, tapering the sides. Remove slightly more clay in the shape of the stem. Then add clay back in the shapes of the eyes, nose and mouth, smoothing the clay into the pan to form a seal. Pour cake batter over the clay and bake!
