I made a big batch of cookie dough last week (with some oatmeal subbed for flour, and butterscotch chips, white chocolate chunks, and dark chocolate chunks subbed for regular chocolate chips.). I haven't yet made actual cookies with it because I like eating dough so much.
So I put white chocolate chunks and dark chocolate chunks in a ramekin and microwaved them for about a minute.
Then I put chunks of cookie dough on top of the melted chocolate.
Chomp! It turned out gooooood :)
