Made these snickerdoodles on the weekend. I actually made some last weekend but I halved the recipe and the biscuits didn't come out quite right, they spread out too much and joined up and I got really cross (and I ran out of cinnamon, the key ingredient). I WILL NOT BE DEFEATED BY BISCUITS. I AM THE BISCUIT QUEEN.
So I made them again. With the full recipe, which makes 80 biscuits, but you can freeze the dough once it's rolled into biscuits. They turned out really well this time, so well I ate about 12 yesterday.

The recipe is from a book called 'Biscotti' produced by the American Academy in Rome. It is hands down the best biscuit book I own, it has mainly Italian biscuits, with a few American recipes (like these snickerdoodles) and even a recipe for anzacs. The Academy employs special chefs and makes lots of biscuits for the residents, unlike the British Academy where I usually stay. They are such good biscuits I am vaguely considering becoming American so I can stay there. Or maybe even ask to be a biscuit fellow rather than an art history fellow...
Anyway here is the recipe, makes 80.
350g caster sugar
340g unsalted butter
vanilla extract
2tsp ground cinnamon
2 eggs
400g flour
2tsp cream of tartar
1tsp baking soda
3/4 tsp salt
Coating
3 tsp cinnamon
1/4 cup of caster sugar
Cream butter and sugar until fluffy, then add vanilla and cinnamon and mix briefly again. Add the eggs one ata time and mix till all well combined.
Sift together flour, cream of tartar, baking soda and salt.
Add the dry ingredients to the butter mixture and mix until combined. Cover bowl and cool mixture in the fridge for 30mins at least (or remove from bowl and wrap in clingfilm/greaseproof).
Remove dough and form into small balls (about 80) At this point you can freeze balls if you want and bake later.
Preheat oven to 190 celsius.
Combine sugar and cinnamon in a bowl and roll biscuit balls to coat and then place them on a tray lined with greaseproof paper. Space them out quite a bit as they will spread, 5-10cm between each depending on the size of the balls.
Bake for 10-12mins, until lightly browned.
Eat.
