Betty Crocker Ice Cream Cone Cakes ?

That's a stupid way to make them. I used to make them many years ago, when my girls were in school. Make up the cake mix batter; stand the cup cones in muffin (cupcake) tins; and fill the cones up about 2/3 way. Then bake them according to the box directions, but start checking them halfway through - the cones have a tendency to crack:) After they're cooled, swirl the tops of the cones in some soft frosting to look like ice cream; and put sprinkles on top..... The directions you gave aren't enough batter to fill the cones, and the bottom of them will be empty.....
