Here is my favorite pecan pie brownies recipe, with a rich, fudgy brownie base, and a gooey pecan pie topping with brown sugar, butter, and plenty of toasted pecans.
These pecan pie brownies are always the first dessert to disappear at potlucks and bake sales. I love making them because you get two desserts in one, and they’re way easier than making a whole pecan pie from scratch.
Why You’ll Love These Pecan Pie Brownies
- Two desserts in one – You get the fudgy richness of brownies topped with gooey pecan pie filling, so you don’t have to choose between your favorite treats.
- Easy preparation with brownie mix – Starting with a box mix means less measuring and mixing, making this impressive dessert way simpler than it looks.
- Perfect for gatherings – These brownies are easy to cut into squares and serve to a crowd, making them ideal for potlucks, holidays, or bake sales.
- Rich and satisfying – The combination of chocolate and caramelized pecans creates an indulgent treat that feels special without requiring advanced baking skills.
What Kind of Pecans Should I Use?
For pecan pie brownies, you can use either raw or toasted pecans, though I personally prefer raw since they’ll toast up nicely while baking in the oven. Pecan halves or pieces both work great here – just make sure to roughly chop them so they’re not too big, which helps them distribute evenly throughout the topping. If you’re buying pecans from the bulk section at the grocery store, give them a quick smell test to make sure they’re fresh, since pecans can go rancid if they’ve been sitting around too long. And if you only have whole pecans on hand, no worries – just give them a rough chop with a knife and you’re good to go.
Options for Substitutions
Here are some swaps you can make to customize these brownies to what you have on hand:
- Brownie mix: You’ll need a box that’s meant for a 13×9 pan – this is important for getting the right texture and thickness. If you only have a smaller box, the layers won’t work out right, so stick with the size specified.
- Light corn syrup: Dark corn syrup works too and will give you a deeper, more molasses-like flavor. You can also use maple syrup, though it’ll change the taste a bit and make it less traditional.
- Pecans: Walnuts are a great substitute if you’re not a pecan fan or just have them in your pantry. You can also try a mix of both for a different nutty flavor.
- Unsalted butter: Salted butter works fine – just skip any additional salt you might be tempted to add. Let it cool slightly after melting before mixing it in.
- Vanilla extract: If you’re out of vanilla, try using almond extract instead, but use only 3/4 teaspoon since it’s stronger. You could also use bourbon for a grown-up twist.
Watch Out for These Mistakes While Baking
The biggest mistake with pecan pie brownies is overbaking the brownie layer before adding the pecan topping, which leads to dry, crumbly brownies instead of fudgy ones – pull them out when they’re just barely set and still look slightly underdone in the center.
Another common error is pouring the pecan mixture onto hot brownies right out of the oven, which can cause uneven spreading and burning around the edges, so let the brownie layer cool for about 10 minutes first.
To avoid a runny pecan topping that never sets properly, make sure your corn syrup mixture comes to a gentle boil and cook it for 2-3 minutes while stirring constantly, which helps it thicken up.
Finally, resist the urge to cut into these right away – letting them cool completely (at least 2 hours) ensures clean slices and allows the pecan layer to firm up nicely.
What to Serve With Pecan Pie Brownies?
These brownies are pretty rich and sweet on their own, so a scoop of vanilla ice cream on top is always a good call – the cold creaminess balances out all that gooey pecan pie filling perfectly. A dollop of fresh whipped cream works great too, especially if you want something a little lighter than ice cream. I like serving these with hot coffee or cold milk, since you’ll definitely want something to wash down the sweetness. If you’re feeding a crowd, set out the brownies on a platter with some extra chopped pecans scattered around for a nice presentation.
Storage Instructions
Store: Keep your pecan pie brownies in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. I actually prefer them cold from the fridge because the pecan pie layer gets nice and firm, making them easier to cut into clean squares.
Freeze: These brownies are perfect for freezing! Cut them into individual squares and wrap each one in plastic wrap, then store in a freezer bag for up to 3 months. It’s great to have a stash ready whenever you need a quick dessert or sweet treat.
Serve: Let frozen brownies thaw at room temperature for about 30 minutes, or enjoy them straight from the fridge if you like them chilled. Some people even love eating them frozen on a hot day—they’re like a fudgy, nutty ice cream bar!

- Fat: 230-260 g
- Carbohydrates: 710-750 g
Ingredients
For the brownie layer:
- 1 box brownie mix (for 13×9 inch pan, plus listed ingredients)
For the pecan topping:
- 1 cup granulated sugar
- 1 1/2 cups light corn syrup
- 4 eggs
- 1/4 cup unsalted butter
- 1 1/2 tsp vanilla extract
- 2 cups coarsely chopped pecans
Step 1: Prepare to Bake
- 1 box brownie mix (for 13×9 inch pan, plus listed ingredients)
Preheat your oven according to the temperature specified on the brownie mix package for a 13×9 inch pan.
Grease a 13×9 inch baking pan to prevent sticking.
This sets you up to work efficiently as you move through the recipe.
Step 2: Make the Pecan Pie Filling
- 1 cup granulated sugar
- 1 1/2 cups light corn syrup
- 4 eggs
- 1/4 cup unsalted butter
- 1 1/2 tsp vanilla extract
In a small saucepan, whisk together the granulated sugar, light corn syrup, eggs, unsalted butter, and vanilla extract.
Place the saucepan over medium-high heat.
Cook, stirring continuously, until the mixture thickens enough to coat your spoon, about 15 minutes.
I always make sure to stir constantly so the eggs don’t scramble and the filling stays smooth.
Step 3: Prepare and Pre-Bake the Brownies
- 1 box brownie mix (for 13×9 inch pan, plus listed ingredients)
Mix the brownie batter according to the package instructions, making sure to incorporate any additional ingredients the box requires.
Pour the batter into the prepared 13×9 inch baking pan.
Bake in the preheated oven for 20 minutes to partially set the brownies.
Step 4: Finish the Pecan Pie Filling
- 2 cups coarsely chopped pecans
- Pecan pie filling from Step 2
Once the filling in the saucepan has thickened (about 15 minutes total), stir in the coarsely chopped pecans.
Continue to cook, stirring, for 2-3 minutes more, until the mixture is the consistency of runny oatmeal—loose enough to pour but not watery.
Step 5: Assemble and Finish Baking
- Pre-baked brownie layer from Step 3
- Pecan pie filling with pecans from Step 4
Remove the pre-baked brownies from the oven.
Immediately pour the cooked pecan pie filling (with pecans from Step 4) over the brownie layer, spreading it evenly to cover the surface.
Return the pan to the oven and bake for an additional 25-30 minutes, or until the filling only jiggles slightly in the center when you move the pan.
For a richer flavor, I sometimes sprinkle a little sea salt over the top right before the final bake.
Step 6: Cool and Serve
Remove the pan from the oven and let the brownies cool completely to room temperature before cutting into bars.
This helps the filling set properly and ensures clean cuts for serving.
