2. 2
   Whisk the butter and sugar together until white and fluffy then fold in the egg and sugar.
3. 3
   Cut the tops off of the oranges about 1/5 of the way down - KEEP the lids!
4. 4
   Scoop out the insides of the oranges with a spoon and either eat or discard.
5. 5
   fill the oranges with the sponge mixture, leaving a bit of room for the cake to rise.
6. 6
   Put the lid back on the orange and wrap up in a double layer of tinfoil.
7. 7
   Bake in the embers of the fire for about 15-20mins until the cake is cooked.
8. 8
   Eat out of the orange with a spoon - it might be an idea to let them cool a bit - especially if you're giving them to kids!
