Ingredients

Brownie Layer

1 18–20 ounce box “Family”-sized brownie mix (plus ingredients called for on the box; I like Ghirardelli)

Pecan Pie Topping

2 cups pecans chopped (walnuts also work well)
4 tablespoons ½ stick butter
¼ cup packed dark brown sugar
½ cup light corn syrup
2 tablespoons heavy cream
1 teaspoon pure vanilla extract
¼ teaspoon ground cinnamon
½ teaspoon kosher salt
Flaky sea salt for sprinkling (optional, after baking)

Instructions

Prepare the Brownies

Preheat oven to 325°F (175°C). Grease and line a 9-inch square baking pan with parchment paper.
Mix and prepare brownies according to package directions.
Pour batter into the pan and spread evenly.
Bake for 25-30 minutes, until the top is set but the center is still slightly underbaked.

Make the Pecan Pie Topping

While the brownies are baking, make the topping.
In a medium saucepan over medium heat, melt the butter. Stir in the brown sugar, corn syrup, and heavy cream. Bring to a gentle simmer and cook for about 2 minutes, stirring constantly.
Remove from heat and stir in the vanilla, cinnamon, salt, and pecans until well coated.

Layer and Bake Again

Increase the oven temperature to 350ºF. Carefully spoon the pecan mixture over the par-baked brownies, spreading evenly.
Return the pan to the oven and bake for an additional 20–30 minutes, until the topping is bubbly and golden.

Cool and Serve

Let brownies cool completely in the pan before slicing (this helps the topping set- about 2-3 hours). Sprinkle with flaky salt if desired.
Cut into squares and enjoy! Pro Tip: For the cleanest slices, chill brownies in the fridge for 1–2 hours before cutting, then bring to room temperature before serving.

Notes

Troubleshooting Pecan Pie Brownies

Brownie Base Issues

Dry or crumbly: Overbaked or not enough moisture.
Too gooey/undercooked: Didn’t bake long enough before adding topping.
Sinking topping: Base wasn’t pre-baked enough.

Pecan Topping Problems

Runny topping: Needs more bake time or filling was too thin.
Burnt topping: Baked too long or oven too hot.
Sinking into brownies: Pre-bake base longer to create support.

Quick Fixes

Pre-bake brownies halfway before adding topping.
Check doneness with a toothpick—should have moist crumbs, not wet batter.
Cool completely before cutting for clean slices.
Use parchment for even baking and easy lift-out.
Double-check oven temp (use an oven thermometer if needed).

Make Ahead, Storage & Freezing

Make Ahead: Bake up to 2 days ahead. Keep whole (unsliced), wrapped tightly at room temp.
Storage: Airtight container 2 days at room temp or 5 days in the fridge (firms the topping).
Freezing: Cool, slice, and wrap pieces individually. Freeze up to 2 months. Thaw at room temp 1 hour or warm in a 300°F oven for 5 minutes.
Pro Tip: Chill before slicing so the pecan topping stays neat and intact.
