I’m a former pastry cook. Here are 6 of my favorite easy ways to upgrade a box of brownie mix.

Most boxed brownies call for a metal or glass baking pan, but there’s some room for variation.

If you bake your brownie in a great cast-iron skillet, it’ll develop crispy edges and a gooey center that everyone can fight over.

To make perfectly portioned, single-serving brownies, use a muffin pan. These are great for on-the-go treats — even if you’re just going to the couch.

No matter what pan you use, though, be sure to grease it with nonstick spray.

If you’re baking brownies, you probably have a hankering for chocolate. Lean into this craving and chop up a bar of your favorite chocolate to toss into the batter.

Even if your mix already has chocolate chips, add in the chopped bits anyway.

Chocolate chips contain stabilizers that help them maintain their shape, but chopped chocolate will create beautiful melted pockets in the brownies.

Any time I can add a savory element to my desserts, I will.

Salty snacks such as kettle chips, pretzels, almonds, or Ritz crackers are a great way to balance out the sweetness in brownies while adding an extra bit of texture.

Plus, you can satisfy your sweet and savory cravings in one fell swoop.

Premade brownie mixes probably already contain vanilla, but you can amp up the flavor with an extra splash of your own vanilla extract. It’s a small bit of effort that can make a world of difference.

You can also switch up the flavor profile with peppermint extract for a festive spin or almond extract for a birthday-cake-like taste.

For an extra kick of richness and a bit of flair, dollop teaspoons of nut butter on top of your unbaked brownies, then swirl it into the batter with a chopstick or butter knife.

I prefer to use unsweetened, salted peanut butter, but you can try almond or pistachio butter. If you have a nut allergy or sensitivity, try swirling in some sunflower seed or granola butter.

The marbled effect of swirling the nut butter into the batter bakes up beautifully and takes only a few extra seconds.

Chocolate and coffee are a dynamic duo.

If you want a subtle way to enhance the chocolate flavor of your brownies, add a teaspoon or two of espresso powder to the batter.

If you’re going for more of a mocha moment, replace the water in the box’s directions with brewed coffee.

Hot tip: Use decaf if you’re craving brownies late at night.
