hmm, cookies is a good idea...
Cookies don't use yeast, they use baking powder.
I suggest you go to your local Goodwill/Salvation Army and find a bread machine. When I've been at Goodwill there always seems to be three of them for like $5 or $10 each, though I suppose covid may have changed that. But if you find one, you can make bread and dough as easy as measuring out some water, flour, oil, salt, and yeast, and hit start. It mixes, rises, and bakes all by itself. Hardly any work. Our favorite thing to do with our bread machine is make pizza dough. Just throw in the ingredients, hit go, 55 minutes later dough is ready. Roll out, top with sauce and desired toppings, through on a preheated pizza stone in your oven at 500 °F for ten minutes and you've got yourself the best pizza you've ever had at home.
If you insist on making a beverage with it I'd suggest cider. Do you have an airlock and a standard stopper? Go buy a gallon jug of apple juice. Pour off two cups of juice. Recap and shake jug vigorously for 30 seconds. Open, throw in a teaspoon of yeast, then put the stopper and airlock on the bottle. Place in a basement or the most temp stable cool (~65-70 °F) place in your house. It should start foaming up in a day or two. Make sure it doesn't foam up through the airlock, then when the foam starts dying down forget about it for a month. After a month go pop the airlock off and enjoy your hard cider.
This is essentially exactly how I've made cider to date, except I sanitize the airlock and stopper with Star San (can also be boiled for a couple minutes in water) and I'm normally making 5.5 gallon batches in a carboy. I also take SG readings at the start and end to calculate ABV, and take notes to hopefully improve my process over time. And I use brewing yeast, I save my baking yeast for the aforementioned bread and pizza dough. The closest I got to my outlined proceedure was my yeast comparison, where I took 4 different yeasts and fermented directly in a half gallon jug of juice I poured a cup of juice out of.
