Tips
Softened butter -- NOT melted!
I've said it before and I'll say it again: DON'T melt your butter. Either leave it at room temp for a couple hours, or chop it into smaller pieces and microwave for 10 second intervals until SOFT, not melted. If you melt your butter the cookies will not hold their shape in the oven.
Refrigerate it
Another thing I live by: refrigerating/freezing my cookie dough before baking. It solidifies the butter again before you bake them. It makes them better. Just do it.
Bake time
My cookies still seemed a little underbaked when I took them out. Their tops weren't set, but they firmed up as they cooled down. If the edges of your cookies are browned, it's time to take them out. The tops will need to cool before you can pick them up.
Calories
Baked goods are often high in sugar, fat, and carbs. As someone who bakes often, I have to watch how much I eat. I love to eat. I do. I also love to have a healthy body. That being said, I appreciate when a recipe states a calorie count. So I've decided to provide that for you.
Total calories: 2,017
Divide that by how many cookies you baked. I made 8, so each cookie is 252 calories. If you used different ingredients, your calories will be different.
Photos!

See how the butter isn't melted? Cream it with the sugar, the add egg and vanilla.

Add flour, baking powder, tartar, and salt.

Chill your dough!

Roll your dough balls in sugar+cinnamon and set them on a cookie sheet.

Golden and beautiful!

If made mine very thick!
Snickerdoodles are a classic. There's something very distinct about them; I assume it's the cream of tartar. And, of course, that cinnamon+sugar combo that you just can't beat. This is a relatively small batch (makes 8), so feel free to double it for more. Mine were gone in one night. Enjoy!
