For stay at home working moms, how do you keep your toddlers busy while you work and no one is available to look after them?

I let my lo play with my baking set like spatula and a bowl. He will put his fruits and vegetables toys to cook as well. Sometimes I will have him involved in my baking, let him beat the eggs. He is very happy that he can work together with me. Recently I made a D.I.Y Play doh for him to play around which helps on his creativity and art works while I'm working next to him.
