Having looked on the internet there is no really good solution to fill a 10cm gap or 2x5cm gaps. Just leave a 10cm gap & use it to store trays etc. or have a re-think & get a 60cm. cooker.

Get a bit of veneered MDF cut it to 100mm width. Fix a few L shaped brackets to the appropriate end and screw the board to the wall or adjacent unit, as appropriate.
Then sort the top out.
BTW maybe you can get a matching 100mm with unit instead.
