Deep Dark Chocolate Sour Cream Bars

READY IN: 50mins
Recipe by mary winecoff

These cookies come from Camilla Saulsbury's Cake Mix Cookies book. My son (age 9) actually made these and they are VERY rich. Kinda a cross between a chocolate cake and a brownie. Perfect for your chocolate lover and very easy to do. Uses a chocolate cake mix.

Thank you for posting these, Mary! They are rich, gooey and delicious! I didn't have a metal pan, so I used my glass one and they came out great! They are hard to cut though, because they are so chocolately, but delicious none the less. Big hit with my family! Easy too! P.S. I'm eating one right now for breakfast...ssshhhhh!
