Personally, I have never had a problem with mine toppling over. I simply place one cone in each cupcake cavity and use a steady hand (preferably two steady hands) when filling the cones and when transferring them to and from the oven. If you're worried about your cones toppling, you can snuggly secure each one by wrapping a piece of crumpled foil around the base of each (pictured in bottom right corner of the overhead photo above).
