I used butterscotch chips - which i HATE but, my very handsome cookie eater loves them, so...needless to say, i was happy to use them. Also, i've seen this recipe a million places but i've adapted this one from allrecipes.com. Here ya go!
2 cups all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
3/4 cup unsalted butter, melted
3/4 cup packed brown sugar
1/2 cup white sugar
1 tablespoon vanilla extract
1 egg yolk
1 cups semisweet chocolate chips
1 cups butterscotch chips
1.Preheat the oven to 325 degrees F (165 degrees C). Grease cookie sheets or line with parchment paper.
2.Sift together the flour, baking soda and salt; set aside.
3. Melt the butter in a heavy stainless steel saucepan.
4. In a medium bowl, cream together the melted butter, brown sugar and white sugar until well blended. Beat in the vanilla, egg, and egg yolk until light and creamy. Mix in the sifted ingredients until just blended. Stir in the chocolate chips by hand using a wooden spoon.
5. Chill the dough for at least 30 minutes.
6. Drop heaping soup spoons of cookie dough onto the prepared cookie sheets. ( I fit about 6 cookies per sheet) Cookies should be about 3 inches apart.
7 .Bake for 15 to 17 minutes in the preheated oven, or until the edges are lightly toasted. Cool on baking sheets for a few minutes before transferring to wire racks to cool completely.
Now! If you have too much batter for one baking (which i did), simply arrange dollops onto a cookie sheet, like you would to bake them, stick the cookie sheet in the freezer for 5 minutes. Take them out of the freezer and pack them into a container, separating the layers with parchment paper, and stick them in the freezer. This way, you can have fresh cookies anytime you want! Impressive or what!!!!!!! Ha!
