There is a video here on betty crocker.com. I used the Betty Crocker line of GF chocolate Chip cookies and Brownie. They are great. I LOVE the brownies with cream cheese frosting! The cakes are great too. The best part of them (besides being good and fast to make) is that if you dont have a GF kitchen, but want to make something GF for someone or for one event, then it is great because you dont have to buy a lot of ingredients. you just need butter, eggs, and the mix.
In seperate bowls, following directions on boxes make the brownies and the cookies.
With a spoon or a cookie dough baller place the cookies in the pan (I used an 8x10 pan)
Fill in the blanks with the brownie mix
Bake in a 350 degree oven for 30 minutes.
