If you're wondering how to make box brownies better, you came to the right place! With just a few little tweaks, you can make boxed brownie mix taste homemade!
Line a 9x9 pan with parchment paper and set aside.In a medium sized bowl, fold together the brownie mix, melted butter, heavy cream and egg yolks until combined. avoid over mixing.
Fold in the chopped chocolate/chocolate chips. Reserve some extra for the top, if desired.
Pour the brownie batter into the 9x9 pan and bake at 350° for 35-45 minutes until a toothpick is inserted and a few moist crumbs are left on the toothpick. If the toothpick comes out completely clean, the brownies will be over baked. The brownies will still be very soft and still jiggle slightly when they come out of the oven.
Allow the brownies to cool completely in the pan prior to cutting and serving.
Store in an airtight container for up to 3 days.
Notes
All brownie mixes are different, please see the back of your brownie box to confirm ingredient amounts. Substitute melted butter for the oil, and heavy cream for the water. Then double the eggs, but use only the yolks.
