I picked up a bag of brownie brittle at the grocery store and loved it, but at $3.99 for 5oz it was not going to be a regular thing. I Googled a few recipes and made my own from a mix. Crispy, chocolaty and crunchy, YUM.
1 box brownie mix that fits a 9X13 pan
1/4C water and oil
1 egg
Nuts or chocolate chips optional I used 1C of chips
Mix together then spread as thin as possible in a parchment lined cookie sheet
Bake at 350 30-40 minutes until the edges start to feel crisp. Turn off the oven and let the pan sit in there for 2-3 hours. Remove from parchment and break into chunks. At 1 Carb for 1 oz and 120 calories it makes a great snack, unless you crumble it on ice cream then it goes higher. Store in an air tight bag.
