Baking Powder instead of soda error
Baking powder is baking soda ($\ce{NaHCO3}$) plus a mild acid salt or dry acid, such as $\ce{Ca(H2PO4)2}$ or tartaric acid. These ingredients should pose no hazard in a stove unless there is remaining powder blocking a vent hole or gas nozzle. In that case, just use a paper clip or other tool to open the vent.

Tartaric acid is theoretically flammable, but the amount you might have left is so small as to be innocuous. You've probably cleaned the stove about as well as baking soda would, once you remove all obvious deposits of the white powder. Bon appétit!
