Start this recipe by placing the orange juice, eggs, vanilla, caster sugar, and oil into a liquidizer and blitz for 3-4 minutes till pale and fluffy. Pour into a large bowl and sift in the flour, baking powder and salt. Add in the zest and fold together well but DO NOT OVERMIX. Pour into a well-greased bunt tin and bake in the oven at 180°C for 35-40 minutes. Allow to cool then mix together the icing sugar, orange juice and cream to make a glace icing. Drizzle over the bunt cake and decorate the top with sliced orange rind.
