This cookie is bananas. Half chocolate chip, half brownie cookie. Now that I know how easy it is to make two different doughs and roll them together into one perfect cookie, I think the possibilities are endless, don't you? WHAT UP, CHRISTMAS COOKIES?! I'M TALKING TO YOU, BOO. Sorry I don't know what that was. I used this recipe but I cut the chocolate chip cookie dough in half. I've written the word "cookie" way too many times in this post. Cookie.
