perfect sugar cookie

2 sticks unsalted butter, grated & kept cold (use European butter if you can, makes all the diff)
1 cup granulated sugar
3/4 cup packed light brown sugar
2 large eggs
1 TB pure vanilla extract
2 ½ cups all purpose flour (13 ½ oz)
1 ts sea salt
1 and ¼ ts baking powder
1/2 ts baking soda 

course sprinkling sugars in various colors

In a bowl mix the flour, baking soda, baking powder and salt, set aside.
In a mixing bowl, mix butter and both sugars until just mixed. It won’t be creamy because butter is so cold—that’s ok. Add the egg and vanilla, mix till just incorporated.

Add in the dry to the wet and mix till just incorporated—never over mix. The dough should be a little dry. We want to mix as little as possible as we don’t want the butter to get too warm nor do we want gluten to start forming—this will give us a nice light, airy, crispy cookie. Place bowl in fridge to chill/firm up. At least an hour, longer if its warm weather.

When ready to bake preheat oven to 375 degrees. You can divide dough how ever you like; I wanted large cookie so I made “almost” golfball sized balls and kept them round as they will spread when baking. Roll the balls in the sugar sprinkles on one side (or both if you desire). Place onto parchment lined cookie trays or non stick cookie trays.  Do not press flat.  Bake for 18-22 minutes—all depending on your oven.  Look for almost golden brown edges.
I got about 15-17 large cookies; if you make them smaller maybe you will get about 30 cookies, I don't know haven't made them small yet.
