I found this all natural brownie mix at Target Stores and it's delicious! Just add YOGURT! I added plain yougurt and works fine! For me was the most delicious brownie that I ever had and it's made with cane sugar, wheat four, cocoa, egg whites, natural vanilla flavor, baking soda, salt & corn starch.
There's 1 with brazilian coffe that it's delicious too! Call Cappuccino or something like that....I forgot.
