Okay so I have a friend who needs me to do a sm. bridal shower cake. She would like the cake to be chocolate, heres where I need ideas. She doesn't want fondant but would like a buttercream with an orange glaze drizzled over it. She would also like a filling in an orange flavor. I could use any advice as to what or how you would do this. Thanks!!

Get some LorAnn candy flavoring or orange extract to flavor buttercream for the filling.
For the glaze, just melt some of that orange b'cream in the MicroWave oven and pour it over the crusted b'cream iced cake.

Have you heard of Terry's Chocolate Orange? Its orange flavoured chocolate, shaped into a orange. If you could find that, you could melt it down and drizzle it over the cake......
