This is one of my mom's favorites! However I cant for the life of me find the pic of it with the icing that actually goes with it. This pic I used just an orange glaze a bit thicker than normal because my daughter wanted the cake for a get together she was having and she doesnt like icings very much. When I find the right pic I will post it. Btw my children did the decorating : )
Lightly spray baking pan with cooking spray. and pre heat oven to 350
Combine the orange soda with the dry cake mix and eggs in a large mixing bowl. Mix together. Pour into prepared pan and bake for 20 to 30 minutes.
Remove cake from oven and poke several holes into the cake with a fork sprayed with cooking spray.
Mix hot water with one box of jello and in a bowl and stir until dissolved. Add cold water and stir well. Pour the jello mix over the cake so it runs down into the holes. Refrigerate cake for at least two hours.
Combine the other box of jello with pudding mix. Add milk and vanilla and mix well. Stir in cool whip. Use this to frost the cake.
