For those who want to bake sphere cakes have a range of ball shaped pans from which to choose, but you do not need a ball pan to make a 3D cake. The ingredients likely sit in your kitchen, and you can use your favorite cake mix or homemade recipe. This cake bakes in two halves at the same time in the oven. This sphere cake forms the basis for cakes resembling soccer or base balls, planets, round fruits or 3D happy faces. Once you bake your sphere cake, the possibilities for what to do with it will only be limited by your imagination.
Preheat the oven to 350 degrees F and spray the interior of both bowls with cooking spray. Apply a light dusting of flour over the cooking spray inside the bowls.
Divide the batter evenly between the two bowls. Place the bowls inside the round baking pans to maintain stability in the oven.
Set the baking pans holding the bowls of cake batter into the oven and bake at 350 degrees F for 35 to 45 minutes or until the cake springs when pressed in the center and a knife inserted into the middle comes out cleanly.
Leave the cakes in the bowls for 20 minutes after baking, then turn the cakes upside down onto a cooling rack to cool completely.
Trim the bottom one inch from the rounded portion of one of the cake halves to create a flat surface for the cake to stand.
Apply a small amount of icing to this cut portion of the cake and turn it onto a serving platter so the icing holds the cut part of the cake down, like a glue. You should now have one half of the cake, resembling an upright bowl in the center of the serving platter for the bottom half of your sphere cake.
Spread a layer of icing over the top of the bottom half of the sphere cake. Insert six or seven toothpicks halfway into the top of the cake in the shape of a circle to help hold the top half of the sphere.
Set the remaining cake upside down on top of the bottom half so you create a sphere with the two halves.
Spread the colored icing over the entire cake for a base of frosting and to cover the seam between the two cakes.
Fill the pastry bag with any remaining icing of a different color and use the decorator tips to write on the cake, make designs like a sports ball or create shapes.
Use only bowls made from oven-safe materials: stainless steel, stoneware, glass or ceramic.
Reduce the oven temperature to 325 degrees F and increase baking time by five to 10 minutes if using ceramic or glass bowls.
