Pecan Pie Brownies

published October 22, 2018 — last updated December 9, 2021

These pecan pie brownies blend rich chocolate and classic pecan pie flavors into one amazing dessert you’ll want to enjoy all year long, not just at Thanksgiving!

If you’re like me, pecan pie is a holiday staple. Now imagine all that gooey, nutty pecan pie filling baked right on top of fudge-packed chocolate brownies. These pecan pie brownies are seriously next-level delicious! The combo of chocolate and pecan pie topping tastes even better than traditional pecan pie alone.

What I love most is how easy this recipe is. I use a boxed brownie mix designed for a 13×9-inch pan to keep things quick and simple, but if you prefer, your own brownie recipe works perfectly. Because the pecan pie filling sinks into the brownies as they bake, the base stays super moist and fudgy. The real star is the pecan pie topping, made using my mom’s classic pecan pie filling recipe.

The magic of pecan pie brownies is right in the name: you get that rich, fudgy brownie paired with a sticky, nutty pecan pie filling on top. This dessert feels special enough to bring to your Thanksgiving table, but it’s also simple and quick enough to enjoy any day when your sweet tooth kicks in.

I keep it easy by starting with a boxed brownie mix for a 13×9-inch pan, but feel free to swap in any homemade brownie batter you love. After pre-baking the brownie base, I make a stovetop pecan pie filling using my mom’s classic recipe. Then it’s just a matter of pouring the filling over the brownies and finishing the bake until the topping jiggles just a little. That’s it!

The end result is a fudgy, moist brownie that soaks up some of that luscious pecan pie topping, creating a gooey crunchy contrast. Below I’ll walk you through exactly what you need, the step-by-step process, and some handy notes to make sure your pecan pie brownies come out perfect every time.

Ingredient Checklist

• 1 box brownie mix (choose one for a 13×9-inch pan) plus eggs, oil, and water called for on the package
• 1 cup granulated sugar
• 1 1/2 cups light corn syrup
• 4 large eggs
• 1/4 cup unsalted butter
• 1 1/2 teaspoons vanilla extract
• 2 cups pecans, roughly chopped

Layering and Baking Steps

1. Preheat the oven according to the directions on the brownie mix box.
2. Prepare the brownie batter following the package instructions.
3. Grease a 13×9-inch pan and pour in the brownie batter.
4. Bake the brownies in the 13×9 pan for about half the package time (about 20 minutes) until partially set.
5. While the brownies bake, whisk together the sugar, light corn syrup, eggs, unsalted butter, and vanilla in a small saucepan.
6. Cook the filling over medium-high, stirring constantly, until it thickens and coats the back of a spoon (about 15–20 minutes).

7. Stir in the roughly chopped pecans and cook 2–3 minutes more until the mixture is pourable but not thin (looks like runny oatmeal).

   

8. If the filling finishes before the brownies, remove it from heat and keep warm until ready to pour.
9. Remove the partially baked brownies from the oven and spread the pecan pie filling evenly over the top.
10. Return the pan to the oven and bake an additional 25–30 minutes, until the filling jiggles only slightly when you gently shake the pan.
11. Let the pan cool completely to room temperature before slicing.

Tips for Best Results

The biggest challenge with pecan pie brownies is getting the brownie base baked just right before adding the filling. I tried lots of different bake times and found that your pan type (metal or glass) and brownie mix brand affect cook time. So, I always use the bake time on the back of the box and pre-bake about half of that (give or take a few minutes). This way, the brownies are fully cooked yet still fudgy once topped and finished baking.

I have to say, the kitchen smell during baking was seriously irresistible! When the pecan pie brownies finally came out of the oven, I struggled to wait for them to cool down. But the wait was worth it — once sliced, everyone who tasted agreed these needed a spot on my Thanksgiving dessert table for sure (browse my favorite Holiday Pie Recipes for more ideas).

Ways to Customize

• Make from scratch: use your favorite 13×9 homemade brownie recipe in place of the boxed mix.
• Change up the nuts: swap pecans for walnuts or a mix of nuts to customize the nutty flavor.
• Extra chocolate: fold in 1 cup chocolate chips into the brownie batter or sprinkle on top of the filling before the final bake.
• Add a twist: replace half the corn syrup with pure maple syrup for a subtle maple flavor (think maple pecan cookies with maple glaze), or add 1-2 tablespoons bourbon to the filling for a warm, boozy depth.
• Mini brownies: bake these in muffin tins or a mini brownie pan; just shorten the overall bake time and check for doneness often.
• Salted finish: sprinkle flaky sea salt on top right after baking for a salty-sweet surprise.

Storage and Freezing Tips

Make sure your pecan pie brownies cool completely to room temperature before storing — this helps keep the filling from sweating.

• Room temperature: Keep covered at room temp for up to 24 hours if you’ll serve soon.
• Refrigerator: Store in an airtight container for 3 to 4 days. Warm briefly or bring to room temperature before serving for softer brownies.
• Freezing: Wrap each slice tightly in plastic wrap, then place in a freezer bag or container for up to 2 months. Thaw overnight in the fridge.
• Reheating: Warm slices in the microwave for 10-25 seconds, watching carefully to avoid overheating, or heat in a 325°F (160°C) oven for 8-12 minutes.
• Make-ahead filling: Prepare the pecan pie filling up to 24 hours in advance (the same style of filling used in Best Ever Pecan Pie Bars); gently reheat on the stove until pourable before using.

Troubleshooting and FAQs

• Can I use a different size pan? Yes! Just keep in mind smaller pans make thicker brownies that need longer pre-baking, while larger pans bake thinner brownies faster.
• How do I know when the brownies are done? Pre-bake your brownies for about half the time on the package or recipe, add the filling, then bake until the filling just barely wobbles. For a visual walkthrough and doneness cues, see this step-by-step pecan pie brownies recipe.
• Why are my brownies soggy under the filling? This usually happens if the pecan filling is too liquidy or brownies weren’t baked enough before topping. Make sure your filling coats the spoon and bake the brownies halfway through their time before topping.
• Can I substitute the corn syrup? Light corn syrup is best for that classic texture. You can replace some or all with pure maple syrup or golden syrup, but expect slight differences in texture and taste.
• Can I make these nut-free? You can leave out the pecans and add extra chocolate chips or seed toppings, but it won’t be pecan pie filling anymore. For a nut-free brownie-based dessert with wow-factor, try Caramel Brownie Cheesecake.
• Is refrigeration required? Because the filling contains eggs, it’s best to refrigerate for storage beyond 24 hours.
