If you love sweet and salty desserts, you're going to love these salted caramel pretzel brownies from brownie mix.
They start with a boxed brownie mix, then get topped with crunchy pretzels and homemade caramel sauce for that perfect mix of fudgy, gooey, and salty in every bite.
This is one of my favorite ways to upgrade boxed brownies when I need something quick but still looks impressive - great for parties, bake sales, or even just when a chocolate craving hits.
And the best part? You don't need fancy ingredients or special baking skills.

Notes and Substitutions
- Brownie mix: Use a standard 18-ounce boxed brownie mix. Any brand works - just follow the package directions.
- Water: You can swap the water for milk, buttermilk, or brewed coffee to give the brownies a richer chocolate flavor.
- Instant coffee: Totally optional, but it makes the brownies taste more chocolatey and less sweet.
Tips for Best Brownies
- Let the eggs come to room temperature, then lightly beat them before adding to the batter. This helps everything mix evenly.
- Grease the pan and line it with parchment paper so the brownies don't stick and are easier to lift out.
- Check a little early so you don't overbake. The toothpick should have a few crumbs on it.
- Don't cut right away. Let them cool, or chill them first if you want cleaner slices.
How to Make Salted Caramel Pretzel Brownies (Step-by-Step)
Step 1: Make the brownie batter using the box directions, then add about 1 cup of pretzels and mix.
Step 2: Spread it evenly on an 8x8-inch pan and top with more pretzels.

Step 3: Bake the brownies as directed on the box, or until a toothpick comes out with a few crumbs.

Step 4: In a small pot, add ⅓ cup sugar and 1 tablespoon water. Cook over medium heat until the sugar turns golden brown.
Swirl the pot once in a while so the sugar cooks evenly. Then, turn off the heat and add 2 tablespoons of butter.

Step 5: Add ¼ cup of heavy cream and put the pot back on medium heat.
Step 6: Keep mixing until smooth. The sauce will thicken as it cools.

Step 7: Pour the caramel over the brownies. Tilt the pan to spread it out, then sprinkle flaky salt on top.
Let the brownies cool in the fridge for at least 1 hour before cutting.

Storage
Keep leftover brownies in an airtight container in the fridge for up to 5 days. Let them sit at room temperature for a few minutes before serving, or warm slightly if you like softer brownies.
