Easy bake oven

Remembering when my lil' sister got easy bake for Christmas, approx' 50 years ago. Heater was incandescent light bulb. 100 watt maybe?
Mom was working for Borden Milk and ice cream too. We already had kids coming around for ice cream. Now we really partying. Our collected coins, soda bottles deposit return, spent on cake mixes. Even the dog gained weight. Then came the half baked cake. We had already caught some flack about the oil and eggs we were using so a new light bulb didn't come quickly.
