We tested our brownie mix over and over and over. My kids ate brownies three to four times a week for over a month and they kept saying keep working on it. I finally figured out that they loved the mix and they just wanted brownies everyday. Kids!
You just need to add 1/2 cup melted butter, 2 eggs and 1tsp vanilla to our mix and you are well on your way to having some of the best tasting brownies. Don't believe me? Ask the kids, they probably ate over 300 brownies each during testing.
