This idea had been churning in my head for quite some time. The first time I heard about baking with diet soda was through Hungry Girl. Lately, I've been seeing many different cake ideas using soda, even "cakes for one", so I decided to give it a GO!
One day, I was rummaging through my pantry when I found a Costco box of Ghirardelli Brownie Mix that was given to us. When we first received it we thought we'd just donate it to the food pantry because, "we didn't need it." However, that day I found it, skinny personal brownies came to mind. So I tried it out using the 3-2-1 method, and it worked like a charm!!
Skinny Brownie (for One):
Baker's Joy (or PAM)
In a small glass prep bowl, mix 3 tablespoons of brownie mix with 2 tablespoons of diet soda. After it fizzes, mix till combined. Pour into another small glass prep bowl, that has been sprayed with Baker's Joy or PAM. Microwave for 1 minute and enjoy!
NOTE: You can skip using two bowls and just mix, then microwave. But to get the glass to come out clean, use a nonstick spray.
