Combining brownies and pecan pie into one dessert sounds like something you'd dream up at midnight when you can't decide what you're craving. These pecan pie brownies have this thick, fudgy chocolate base topped with that classic gooey pecan pie filling that gets all caramelized and sticky in the oven. I made these for Thanksgiving a few years back when I was supposed to bring either brownies or pie but couldn't make up my mind, so I just made both at the same time. My uncle took one bite and declared them "dangerously good," then proceeded to eat three squares before dinner was even served. Now my family requests these specifically every holiday, and I've caught people sneaking into the kitchen to grab extras when they think nobody's watching.

My neighbor Dave is one of those guys who claims he doesn't really like dessert and never eats sweets. His wife brought him to our Christmas party last year, and I watched him take a polite small square of these brownies to be nice. He finished it in about four bites, looked at his empty plate like he couldn't believe it was gone, then went back and cut himself a bigger piece. His wife was laughing because apparently he never goes back for seconds on dessert. He told me later that week he'd been thinking about those brownies constantly and asked if I could make them again. Now I make an extra pan just for him every time we have a gathering.

What Goes Into Them

  • Boxed brownie mix: Two boxes (e.g., Triple Chocolate Fudge) create that rich, chocolatey base.
  • Water for brownies: Just a quarter cup, less than box directions, to keep the base fudgy.
  • Canola oil: A full cup makes the brownies incredibly moist and fudgy.
  • Eggs for brownies: Four large eggs bind everything for a dense, fudgy texture.
  • Granulated sugar for topping: A quarter cup for sweetness in the pecan filling.
  • Brown sugar: Another quarter cup adds molasses flavor and aids caramelization.
  • Cornstarch: Two tablespoons thickens the pecan filling so it sets up properly.
  • Light corn syrup: Provides the signature gooey texture and sweetness.
  • Unsalted butter: Four tablespoons melted, adds richness to the filling.
  • Kosher salt: Half a teaspoon balances all the sweetness.
  • Eggs for topping: Two eggs lightly beaten, help the pecan filling set like pie filling.
  • Chopped pecans: A cup and a half for crunch and nutty flavor throughout the topping.
  • Pure vanilla extract: One teaspoon enhances all the other flavors.

Making These Brownies

Getting everything ready:
Preheat oven to 325 degrees. Line a 13x9 inch baking pan with parchment paper, leaving overhang on the sides to use as handles.
Creating pecan filling:
In a medium saucepan, whisk together granulated sugar, brown sugar, cornstarch, light corn syrup, melted butter, kosher salt, and lightly beaten eggs over medium heat. Stir constantly, scraping the bottom and sides, until the mixture reaches a full rolling boil. Remove from heat immediately. Stir in chopped pecans and vanilla extract until coated. Pour into a separate bowl and cool for 10 minutes at room temperature, then chill in the refrigerator for a full hour. (This chilling step is important to thicken the filling and prevent sinking).
Mixing brownie batter:
In a large mixing bowl, combine both boxes of brownie mix, 1/4 cup water, 1 cup canola oil, and 4 eggs. Beat with a hand mixer on medium speed for 1–2 minutes until you have a thick, smooth batter.
Baking the base:
Pour the batter into the prepared pan and spread into an even layer. Bake for **44 minutes**. The brownies are done when the edges are set and the center has a slight wobble; a toothpick should come out with moist crumbs, not wet batter. Cool completely in the pan until comfortable to touch (30–45 minutes).
Adding pecan topping:
Lift the cooled brownie slab out of the pan using the parchment handles and transfer it to a cutting board. Pull the chilled pecan topping out of the refrigerator and use a spatula to spread it evenly over the entire surface of the brownies, going all the way to the edges.
Slicing into squares:
Use a large sharp knife to cut the brownie slab into squares (e.g., a 6x4 grid for 24 pieces). Wipe the knife clean between cuts for neat edges. Serve at room temperature or slightly chilled.

I messed up the cooling step my first time making these because I was impatient and didn't want to wait. I spread the pecan topping on while the brownies were still pretty warm, and it immediately started sinking down into them and mixing with the chocolate. The finished product still tasted good but looked like a muddy mess instead of having those nice distinct layers. Now I force myself to wait until everything is completely cool, and the layers stay separate and beautiful.

The chilling time for the pecan filling seemed excessive when I first read the recipe, like maybe I could skip it or just do 20 minutes. But when you try to spread unchilled filling, it's too liquidy and runny, and it just pours off the brownies onto your counter instead of staying where you put it. After an hour in the fridge, it thickens up to this perfect spreadable consistency that stays put. That hour is worth the wait.

Serving These Treats

Arrange these brownies on a serving platter or cake stand for holiday dessert tables (Thanksgiving, Christmas, fall gatherings). Cut them into smaller squares for parties or bigger pieces when they are the main dessert. Serve at room temperature for a softer texture, or chilled for a firmer texture. These pair beautifully with vanilla ice cream or fresh whipped cream on the side, or with a cup of strong coffee to balance the sweetness.

Different Ways to Make Them

  • Use **dark chocolate brownie mix** for a more intense, less sweet chocolate flavor.
  • Add a layer of **chocolate chips** between the brownie and pecan topping for extra chocolate.
  • Mix **bourbon** into the pecan filling for a grown-up version.
  • Use **walnuts** instead of pecans.
  • Drizzle **melted chocolate** over the top of the pecan layer for decoration.
  • Add **cinnamon** to the pecan filling for warmth.
  • Make these in a **muffin tin** for individual brownie cups.
  • Sprinkle **sea salt** over the top before serving for a salted caramel effect.

Storage and Freshness

  • These brownies keep at **room temperature** in an airtight container for up to 4 days, and often taste better on day two.
  • Store them in the **refrigerator** for a firmer, chilled texture.
  • You can **freeze** these for up to 3 months wrapped in plastic wrap and foil. Cut them into squares before freezing for easy thawing.
  • Thaw frozen brownies overnight in the refrigerator or at room temperature for a few hours.

I've made these pecan pie brownies so many times now they've become my signature holiday dessert that people expect and request. There's something really satisfying about combining two classic desserts into one thing that's somehow better than either would be separately. The fudgy chocolate base provides this rich, intense flavor while the sweet, nutty pecan topping adds texture and that nostalgic pie taste everyone loves. They look impressive when you cut into them and see those two distinct layers, like you spent way more time and effort than you actually did. These have earned their place in my permanent holiday rotation.

Frequently Asked Questions

→ Can I use homemade brownies instead of a box mix?
Absolutely! Any fudgy brownie recipe will work. Just bake the brownies according to your recipe, then add the pecan topping.
→ Why do I need to chill the pecan topping?
Chilling it helps the mixture thicken and set up so it spreads easier on the brownies without being too runny. It also prevents it from soaking into the brownies too much.
→ Can I put the pecan topping on before baking?
No, the topping is added after the brownies are baked and cooled. If you bake it together, the pecan layer won't have the right texture.
→ How do I store these brownies?
Keep them in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. They're good cold or at room temperature.
→ Can I use a different type of nut?
Sure! Walnuts would be a great substitute for pecans. You could also try a mix of nuts if you want.
→ How many brownies does this make?
A 9x13 pan usually makes 12 to 16 brownies depending on how big you cut them. These are pretty rich, so smaller squares might be better.

Ingredients

→ For the Brownie Base

01 2 boxes Betty Crocker Triple Chocolate Fudge brownie mix
02 1/4 cup water
03 1 cup canola oil
04 4 large eggs

→ For the Pecan Pie Topping

05 1/4 cup granulated sugar
06 1/4 cup brown sugar
07 2 tablespoons cornstarch
08 3/4 cup light corn syrup
09 4 tablespoons unsalted butter, melted
10 1/2 teaspoon kosher salt
11 2 large eggs, lightly beaten
12 1 1/2 cups chopped pecans
13 1 teaspoon pure vanilla extract

Instructions

Step 01

Heat your oven to 325 degrees.

Step 02

Line a 9x13 inch baking pan with parchment paper. This makes it super easy to remove the brownies later.

Step 03

In a medium saucepan, combine the granulated sugar, brown sugar, cornstarch, corn syrup, melted butter, salt, and beaten eggs. Stir everything together constantly over medium heat and bring it to a boil.

Step 04

As soon as it starts boiling, take the pan off the heat. Stir in the chopped pecans and vanilla extract, making sure everything is evenly mixed. Pour the mixture into a bowl and let it cool on the counter for about 10 minutes, then pop it in the fridge for 1 hour to set up properly.

Step 05

While the topping is chilling, make the brownie base. In a large bowl, use a hand mixer to blend together the brownie mix, water, oil, and eggs until the batter is smooth and consistent.

Step 06

Pour the brownie batter into your prepared pan and spread it out evenly. Bake for 44 to 47 minutes until the brownies are fully baked but still have that fudgy center. Don't overbake them.

Step 07

Once the brownies are done baking, let them cool in the pan until they're comfortable to touch. Carefully lift the whole brownie slab out using the parchment paper and transfer it to a cookie sheet.

Step 08

Take your chilled pecan pie topping out of the fridge and spread it evenly over the top of the cooled brownies.

Step 09

Cut the brownies into squares and enjoy! These are seriously good.

Notes

  1. The pecan topping needs to chill for 1 hour, so plan ahead or make it the day before.
  2. Store these in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week.
  3. These are perfect for holidays, potlucks, or any time you want something extra special.
  4. You can use any brand of brownie mix, but the triple chocolate fudge makes them extra rich.
