This is what we (the family) had for dessert tonight to go along with our BBQ. I had seen this on a few different blogs and have been dying to try it.
Just make a chocolate cake mix. Cut oranges in half and scoop out the middle. Pour the mix into the orange, wrap it up in tin foil. We stuck it on the grill since we were already BBQing, but I have seen it done in a camp fire and I am sure you could also bake them in the oven. My mom also made a glaze to put on top with the orange juice and some powdered sugar! It was the perfect topping.
You can eat it right out of the orange and its delicious!
