1- Start with good brownie mix!

This first tip sounds like a given, but I can’t tell you how many times I have gotten the wrong brownie mix and ended up with something that tasted like chemicals and despair.

One of my favorite brownie mixes to start with will have to be the Ghirardelli double or triple chocolate brownie mix or the Ghirardelli chocolate supreme.

Using a good brownie mix to start will make your final doctored up brownies taste even better!

2- Use butter instead of oil

Butter, butter, butter. My number one love when it comes to baking. Most brownie mix boxes suggest that you use oil but to add more richness to your brownie mix brownies, opt for melted butter.

Bonus points if it’s really good quality butter!

3- Use egg yolks instead of a whole egg

As a rule of thumb, you should know that 2 egg yolks make a whole egg. I love using 2 egg yolks instead of one whole egg in my boxed brownie recipe because it increases the fat content of the brownies and keeps them way more fudgy.

This is a simple swap that will yield amazing results! For those extra egg white you can make some meringue cookies

4- Use milk or heavy cream instead of water

When it comes to making brownies fudgy, you want to increase the fat of the brownie batter and that’s where the milk or heavy cream comes in to play.

If you think about it, adding in water to your brownie mix is boring. It doesn’t add anything special to the recipe while the milk or heavy cream both add some depth, some richness, and extra fat for the perfect ooey gooey brownie slice.

5- Use hot brewed coffee instead of water

You know what’s a match made in heaven? Coffee and chocolate! Many chocolate cake recipes require you to add hot brewed coffee into the cake mix to give it that intense chocolate flavor.

Same for these brownie mix brownies, using coffee instead of plain old water will help intensify the chocolate flavor and make them even better.

6- Add some vanilla extract

Adding vanilla might seem a bit odd especially since we are talking about chocolate brownies. But trust me, the vanilla extract will add an extra depth of flavor that will also enhance the other ingredients in the brownie, AKA the chocolate!!

7- Add s little salt to the boxed brownie batter, and sprinkle some more on top while you’re at it!

If you have ready my recipes before, you will notice that I always add some salt to my baked goods to balance out the sweetness of whatever I am baking.

Same goes for these boxed brownies. Adding a little bit of salt to the batter will add an interesting deep chocolate flavor without being too sweet.

Bonus points if you sprinkle some sea salt on top because you were feeling fancy!

8- Add in Espresso powder or instant coffee

This brownie mix hack is very similar to the one where you can add hot coffee instead of water. But I especially like this one because it allows you to add coffee to get that depth of flavor while also adding milk as the liquid to add richness and extra fat to make your boxed brownies more fudgy.

To use this hack, add 1-2 tsp of espresso powder or instant coffee to your brownie mix batter and enjoy that intense chocolate flavor!

9- Avoid over-mixing your boxed brownie mix batter

This is a tip that I live by when it comes to cakes and cookies but surprisingly enough, it applies to brownies too!

Over mixing your brownie batter will result in a dense and not fudgy brownie so mix just until the dry mixture disappears, transfer to your baking pan and bake right away.

10- Change up the baking directions for low and slow bake. This yields an extremely fudgy brownie.

Not all boxed brownie mix are created equal, and many of them have different baking instructions. My favorite way to bake boxed brownie mix is to lower the heat to 325F and bake the brownies for 40 minutes or until a toothpick inserted about an inch from the edge comes out clean or with a few dry crumbs.

Extra tips on how to make boxed brownies better!

How many eggs should I put in box brownies?

The back fo the brownie mix box usually asks for 2 eggs and that’s what I like to stick with because I prefer a fudgy brownie. You can also use 2 eggs and an egg yolk to increase the fat amount in the brownie which will then result in a fudgy brownie.

Make sure to use room temperature eggs though to allow everything to get incorporated together better.

What pan should I bake my brownies in?

I have baked my brownies in a glass pan as well as a metal pan. I personally prefer my USA Pan because it is lighter in color and gives me the perfect sharp edges.

If you are baking in a glass pan, add about 4-5 minutes of bake time because it takes a little longer to heat up.

Also, try and bake in a lighter colored pan because it will distribute heat more evenly. If you don’t have anything that’s lighter, reduce your baking time by a few minutes.

How to cut brownies

How to cut brownies cleanly?

This one is one of my favorite bets kept secrets ever! The biggest thing when it comes to cutting brownie slices just like food bloggers is to chill your brownies in the fridge for an hour or more before slicing into them.

Then use a long knife to cut into the brownies, making sure to wipe the knife down with a damp towel between each slice! This is super important especially if your brownie is more on the fudgy side.

How to freeze boxed brownies?

This all depends on if you want to freeze your brownies before or after slicing into them.

If you want to freeze the brownie whole, wrap it tightly in aluminum foil then place it in an airtight container and freeze for up to 3 months.

If you want to freeze the sliced brownies, wrap each one individually in aluminum foil then place them all in an airtight container and back in the freezer for up to 3 months.

Once you’re ready to enjoy them, pull them out of the freezer and let them thaw in the fridge overnight! I always like to pop them in the microwave for a few seconds for that extra fudgy texture!
