Printable Recipe

3/4 cup (1  1/2 sticks) butter, melted and cooled
1/2 cup granulated sugar
1 cup brown sugar
1 egg
1 egg yolk
1 tbsp vanilla (yes, 1 tbsp!)
2 cups flour
1/2 tsp baking soda
1/2 tsp salt
2 cups semi sweet chocolate chips
plain M&Ms, optional

Cream the melted and cooled butter, sugar, and brown sugar until light and fluffy. Add the egg and egg yolk, one at a time, beating well. Add the vanilla and beat well. In a separate bowl, combine the flour, soda  and salt. Stir in the flour mixture just until combined. Stir in the chocolate chips. Drop by spoonfuls on cookie sheets and bake 325 degrees for 10 - 12 minutes, or until lightly golden brown. Cool on cookie sheets a few minutes before removing to cool on a wire rack.

I like to top these with plain M&Ms before baking. I also will form some dough into a log and wrap it in parchment paper, and then freeze it for up to a month. When ready to bake, simply cut the log into slices, about 1/2" thick and bake. You don't really even need to thaw out the dough first.
