8 of the best ways to upgrade a box of brownie mix, from a professional baker

Try using milk or cream in place of water when mixing the batter.

This will still check the liquid off the ingredient list while creating a richer, fudgier, moister brownie.

A plain brownie batter is calling for mix-ins, and the possibilities are endless. Consider adding chocolate chips or dark-chocolate chunks.

Crushed Oreo cookies, M&M's, Reese's Pieces, chopped walnuts or hazelnuts are excellent options as well.

Fold them in once the batter is prepped, and then transfer to the baking pan to bake as directed.

Switch up the flavor of boxed brownies with just a few drops of an extract. Even just a teaspoon of vanilla extract can go a long way in enhancing the flavor of this treat.

You can also play around — adding peppermint extract will offer a chocolate-mint combo that's wonderful for the holiday season.

Coconut extract is another great pairing to try, maybe even paired with shredded coconut folded into the batter.

Most brownie mixes call for a few tablespoons of water on the back of the box. To enhance your brownies, swap that water out for strong brewed coffee. This can add a more complex depth of flavor.

For an even more pronounced coffee flavor, add a teaspoon of instant espresso powder to the dry ingredients as well.

Once the brownies are baked, the sky's the limit.

You could serve them as-is, or dress them up further. Consider adding frosting to the top, whether you want double-chocolate brownies with mint frosting or peanut-butter icing.

Chocolate ganache or salted-caramel sauce are excellent toppers, too.

To upgrade your brownies and curb their sweetness, try adding some of your other favorite snack foods to them.

Opt for salty mix-ins, like crushed pretzels or salted peanuts. You can also crumble up ridged potato chips or kettle chips and sprinkle them over the batter before baking.

Combine two beloved desserts in one with this trick.

Make the brownie batter according to the instructions on the box. Then, combine one block of softened cream cheese, 1/3 cup granulated sugar, one egg, and one teaspoon of vanilla extract. For best results, use a hand mixer or stand mixer.

Dollop the cream-cheese mixture over the brownie butter and use the back of a spoon or a butter knife to swirl the top. Bake the brownies as directed, and you'll end up with dreamy cheesecake brownies.

This sounds wildly simple, but it can make a huge difference. Just a touch of flaky sea salt will not make brownies look pretty and enhance their flavor tenfold.

Before the brownies go into the oven, sprinkle flaked sea salt on top. Then, bake as directed.
