This is one of the best desserts ever! I've been making a lot of cakes lately, so my husband decided that he wanted something else for his birthday. He requested chocolate chip cookies and brownies with ice cream. So, I put the cookie dough in the bottom of a 9 x 13 inch pan, and then poured the brownie batter on top! I baked it about 30 minutes at 300 degrees (although my oven cooks hot, so that would be 350 in a normal oven). It's amazing! We served it with ice cream too, yum!
