Proofing pizza dough with an electric oven I used to make pizza dough effortlessly when I had a gas oven.  The pilot was enough to keep a warm temperature.
My last two ovens have been electric ovens.  I have tried many approaches, including keeping a hot water bath in the oven with the dough, and leaving the light on.  But have had no success in getting a good raised proof.
Are there any surefire methods to proof pizza dough with an electric oven?
No, an electric oven is not especially well suited as a device for speeding up dough proofing.
The closest you can get is by turning the oven on at the lowest level, without preheating, and babysitting it. Provided that you have a standard, large oven, it is unlikely that you kill the yeast - but you really have to pay attention to it, so it is labor-intensive, and not actually surefire.
If you insist on a warm proof, you will have to buy or construct a separate proof device.
