I'm not joking. Here we go:
Blue Ribbon Chocolate Chip Cookies
Here's what you need:
1/2 cup (1 stick) unsalted butter
1/4 cup shortening
Of course you can just use 3/4 cup butter if you don't have any shortening, but shortening improves the consistency and makes them taste better.)
1 cup packed brown sugar (I use light brown.)
1/2 cup white sugar
1 TB vanilla extract
1 egg
1 egg yolk
