This was a copy off another CC user. I say it wasn't easy! The bottom of the box is victoria sponge and the lid is lemon drizzle cake. I used an impression mat and then hand painted in the grooves. For anyone wanting to try, the biggest tip I can give is to only just leave a faint impression and free hand paint over it. That is so much easier than trying to fit even the thinnest of paintbrushes in the gaps.
