Learn how to elevate your box mix brownies with one ingredient and bring them to a whole new level. I love brownies! But I don’t always want to make them from scratch; sometimes I am just too busy, so it is nice to have a box mix or two handy in the pantry. After trying this simple method, you will never want to make box mix brownies any other way.
Ingredients

To make box mix brownies even better all you need are a few simple ingredients. You won’t be following the instructions on the back of the box or the ingredients listed there, except for the eggs:
- Your favorite brownie mix
- Eggs
- Sweetened condensed milk

Equipment/Tools
- Large bowl
- 8×8 to 13×9 baking pan
- Parchment paper, optional
- Sturdy spoon
- Mixer is optional
How to elevate your box mix brownies with this ingredient

Preheat the oven to 325°F or 162°C.
Add the eggs and the sweetened condensed milk to a large bowl and mix until well combined.

Now add the brownie box mix dry ingredients, about half of it at a time, and mix until well incorporated. If you would like to add chocolate chips of nuts, you can do so now.
Pour the brownie batter into an 8×8-inch pan that is lined with parchment paper or sprayed with cooking spray. If you want thinner brownies, use a larger pan, up to a 13×9-inch pan. Spread the batter evenly. Then bake for 45 to 55 minutes until a toothpick comes out nearly clean.

Allow the baked brownies to cool for about 30 minutes, then you can cut them into squares. A little trick to cutting the brownies easily is to use a plastic serrated knife. Enjoy!
Can I substitute the eggs?
Yes, you can. If you don’t want to use eggs, try using 1/2 cup of applesauce.
How long do box mix brownies last?
They will last up to a week if stored in an airtight container. Freeze them after that.
