Pecan bars are essentially pecan pie in a format that slices cleanly, stacks without drama, and travels well. The crust is a pressed shortbread — no rolling, no chilling — and the filling sets firm enough to cut into 16 neat bars once fully cooled. If you want something homemade that holds up in a tin or a gift box, this is a reliable choice.
What makes this version work
Two things matter most here. First, the crust gets a full 20-minute pre-bake before the filling goes on. That step keeps the base from turning soggy under the wet filling — skip it and you’ll get a greasy, underdone bottom layer. Second, the filling is built off the heat: you melt the butter, pull the pan, then whisk in the corn syrup and brown sugar before the eggs go in. Adding eggs to a hot mixture risks scrambling them, so the order isn’t arbitrary. Get both of those right and the bars will set with a firm, slightly chewy top and a clean edge when sliced.
Mistakes to avoid
- Cutting too soon: The filling needs to cool completely — at least 2 hours at room temperature — before you cut. Rushing this gives you bars that ooze at the edges and fall apart. If you’re packaging them, refrigerate for 30 minutes after they’ve cooled to room temperature for the cleanest cuts.
- Uneven crust thickness: Press the dough into the corners and edges as carefully as the center. Thin edges overbake and crumble; thick corners stay doughy. Use the flat bottom of a measuring cup to get an even layer.
- Skipping the parchment: The recipe says to grease the pan, but lining it with parchment and leaving an overhang on two sides means you can lift the whole slab out before slicing — far easier than cutting in the pan and prying bars out.
- Overfilling the pan: Pour the filling slowly. If it creeps up the sides and slides under the crust, the base will separate. Stop pouring when the filling reaches about a quarter inch from the top of the crust.
- Using warm pecans after toasting: If you toast the pecans first, let them cool completely before stirring them into the filling. Hot nuts raise the temperature of the filling and can partially cook the eggs before the bars even hit the oven — skip the garnish of whole pecans pressed on top for the same reason, not worth the extra step.
Make-ahead notes
These bars are genuinely better made a day ahead. Once fully cooled, wrap the uncut slab tightly in plastic wrap and store it at room temperature for up to 2 days, or refrigerate for up to 5 days — the filling firms up nicely in the fridge and the bars slice even cleaner when cold. For gifting, cut them after refrigerating, layer between sheets of parchment in an airtight tin, and they’ll hold at room temperature for 2 days without sticking together. For longer storage, the bars freeze well for up to 3 months; wrap individual bars in plastic, then foil, and thaw overnight in the fridge rather than at room temperature to keep the filling from weeping.

Equipment
- 9x13 inch baking pan
- Saucepan
- Mixing Bowls
- Whisk
- Measuring cups and spoons
Ingredients
Crust
- 2 cups all-purpose flour
- ½ cup unsalted butter cold and diced
- ½ cup granulated sugar
- ¼ teaspoon salt
- 1 large egg beaten
Filling
- ½ cup unsalted butter melted
- 1 cup light corn syrup
- 1 cup brown sugar packed
- 4 large eggs beaten
- 1 teaspoon vanilla extract pure
- 1 ½ cups pecans coarsely chopped
Instructions
Preparation Instructions
- Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan.
- In a mixing bowl, combine 2 cups of flour, 1/2 cup of granulated sugar, and 1/4 teaspoon of salt. Add 1/2 cup of cold, diced butter to the mixture and work it in with your fingers or a pastry cutter until it resembles coarse crumbs.
- Add 1 beaten egg to the flour mixture and mix until combined. Press the dough evenly into the bottom of the prepared pan.
- Bake the crust for 20 minutes or until lightly golden. Let it cool on a wire rack.
- In a medium saucepan over medium heat, melt 1/2 cup of unsalted butter. Remove from heat and whisk in 1 cup of corn syrup and 1 cup of packed brown sugar until smooth. Gradually whisk in the 4 beaten eggs and vanilla extract until completely combined.
- Stir in the coarsely chopped pecans into the filling mixture, then pour the filling over the baked crust.
- Bake for an additional 25 minutes, or until the filling is set and slightly golden. Let it cool completely before cutting into bars.
Notes
Lori’s Tips
- To enhance flavor, consider toasting the pecans prior to adding them to the filling.
- For a more nuanced sweetness, replace half of the corn syrup with maple syrup.
- These bars freeze well, so make them ahead of time and store for up to 3 months.

Your questions, answered
Can I use dark corn syrup instead of light?
Yes, but the bars will taste noticeably more molasses-forward and the color will be much darker. Light corn syrup gives a cleaner, more neutral sweetness that lets the brown sugar and pecans come through — dark corn syrup works if you like a stronger, almost bittersweet edge.
How do I know when the filling is actually set and not just browned on top?
Give the pan a gentle nudge at the 25-minute mark — the filling should jiggle slightly as one unit in the center, not ripple like liquid. If the edges are firm but the middle still moves independently, give it another 3 to 5 minutes and check again.
Will the bars get sticky if I’m packaging them as gifts?
They can if they’re stacked directly on each other, especially in a warm room. Place a small square of parchment between each bar before boxing them up, and they’ll stay separate and presentable for up to 2 days at room temperature.
