long long, Rose has always been an advocate of the Sharp countertop microwave oven with convection.  the turntable is around 16” wide and you can fit up to 2 12-inch layer cakes, stacked with the grill rack.  I have a similar one, Panasonic, and works very very well.  It is recommended to turn off the convection fan, however nowadays, Rose recipes seem to be moister, so keeping the fan on is just fine, specially for the bundt aluminum and the silicone pans.

what is your experience?

i am eying for the sanyo one, it is smaller and seems perfect for most cakes we do.  much friendlier than turning the big oven on.  what do you think?  seems that turning the fan off isn’t an option.

Hector did you receive any more information on this. I have thought about a Sharp convection oven but would have imagined it was too hot for cakes??

Has Rose used them?

Rose has two Sharp convection microwave ovens, these are about 20 years old, 1.5 to 2.0 cu ft and made in Japan.  These came out when full size microwave ovens were on demand.  I have a very similar one, Panasonic Genious oven.

The Sanyo oven I listed above is a much smaller unit and I believe it does not have the option to turn off the fan which is something undesirable for layer cakes.  Cuisinart makes a similar unit.  I haven’t tested these yet, but look promising.
