Add dry ingredients and start mixing. I recommend using an electric hand mixer.
Spoon into a pan and smooth it out. For best results use a cupcake pan.
I baked it at 350 degrees for 15 minutes.
For maximum freshness, put each "meal" worth into a bag and refrigerate the bag. My guess is that it will keep just like the brownies you are familiar with. Out of the fridge they should be good for 1-3 days.
