Step #1
Slice the oranges in rounds (you can juice the off-cuts and use them as the orange juice for the cake).
Step #2
Put the oranges in a pot of boiling water on the stove and boil for 2-3 minutes. Repeat the process with clean water (we do this to reduce the bitterness from the orange skins). Place the oranges on a clean cloth or kitchen roll to pat dry. In a bowl, mix together the Orange Cake Mix, orange juice, water and oil and mix well.
Step #3
In three tins, place a greaseproof paper round, sprinkle the light brown sugar and place the orange slices on top. You can either do this for just the top layer, or for all layers.
Step #4
Place around 250g of the cake mix on top of each and spread evenly.
Step #5
Bake as per the suggested temperature on the BOP for 18-22 minutes (oven dependant). For the buttercream, combine the ingredients and mix until the buttercream is lighter in colour and smooth/fluffy.
Step #6
Once the cakes have cooled, layer the cakes with the buttercream between each layer. Feel free to add Orange jam inbetween too!
