You can just melt the butter. It makes the cookies a little chewier, but works just fine.

Just make some basic chocolate chip cookies - you don’t need all that extra

Stand mixer is someone standing with a fork they spin around. A silicon baking sheet costs fourteen bucks and prevents uneven heat transfer to avoid burning the edges. Name one recipe that calls for crystallized yak butter. 🧑🏼‍🍳

I make cookies all the time and I don't own any of that. Especially no yak🤣

I was always taught to cream butter and sugar with a wooden spoon and “elbow grease”🥴. Still makes the best cookies! Never used a mixer in my life!

As a pastry chef I will say ....check king Arthur Flour website. They have marvelous recipes from simple to very complex. Best of luck with your cookies!

Get a basic cookbook. Betty Crocker or Good Housekeeping. They won't ask for exotic ingredients.
