ice cream & cookie sandwiches

One of my favorite combos would be cookies and ice cream, so to make a sandwich with them is just fabulous. Whoever thought of the ice cream sandwich gets a gold star in my book!
We made the cookies from scratch, using the first chocolate chip cookie recipe ever, Nestle Tollhouse.

We then used Ben & Jerry's Chocolate Fudge Brownie ice cream. It was a good flavor combo, but I like the classic vanilla ice cream in the middle of my chocolate chip cookies. What about making cookie sandwiches with chocolate cookie dough ice cream? or is that going too far? There are so many different cookie flavors and ice cream flavors, the possibilities are endless!
