depends on the power used by the oven and the time it is turned on.

eg, if the oven is 5 kW and you turn it on for 2 hours, that is 10 kW-hr

$0.15/k-Wh x 10 kW-hr = $1.50

Is it a gas oven?

? · Answer

For a 5 kW oven operating for 12 minutes (one batch),
cost = 5kW * (1/5 h) * $0.15/kWh = $0.15 ◄ a

If you do ten batches of cookies, that takes two hours, and
cost = 5kW * 2h * $0.15/kWh = $1.50 ◄ b
