Pecan Pie Bars (Buttery Shortbread Crust, Sticky Pecan Filling, Cuts Like a Brownie, 1 Hr 15)

This is the holiday baking upgrade that lets me feed a crowd without dealing with pie crust drama. Pecan pie bars takes a buttery shortbread crust pressed into a 9×13 pan and parbaked, then tops it with classic pecan pie filling (corn syrup, brown sugar, butter, eggs, vanilla, and a generous mound of chopped pecans) and bakes until set with a slight wobble — cools completely, then cuts into 24 perfect squares.

Fun fact: pecan pie was invented in the 1920s when Karo corn syrup company published their first pecan pie recipe on the back of their syrup bottles as a marketing campaign. Before then, Americans used molasses or honey for sweet pies. The corn syrup version became the dominant recipe because it gave that signature glossy chewy texture that defines modern pecan pie. The bar version is a 1980s Southern Living invention.

Why this recipe works

PARBAKE the crust 15 minutes. Wet pie filling on raw dough = soggy bottom. Parbaked = crispy buttery base.
Pull when CENTER WOBBLES. Like jello — not liquid, not firm. Sets fully as it cools (4 hours minimum).
COOL COMPLETELY before cutting. Hot bars are gooey messes. 4 hours minimum, ideally overnight, before slicing.

Ingredients

Makes 24 bars.

Shortbread crust:
2 cups all-purpose flour
1/2 cup powdered sugar
1 cup (226 g) cold unsalted butter, cubed
1/2 tsp salt
Pecan pie filling:
4 large eggs
1 cup light corn syrup
1 cup brown sugar (packed)
4 tbsp (57 g) unsalted butter, melted
2 tsp vanilla extract
1/4 tsp salt
3 cups pecan halves (roughly chopped, save 1 cup for topping)

Instructions

Step 1: Preheat and line pan

Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving overhang on the sides for easy removal.

Step 2: Make the shortbread crust

In a food processor, pulse flour, powdered sugar, salt, and cold cubed butter until coarse crumbs form. (Or use a pastry cutter by hand.) Press the mixture firmly and evenly into the prepared pan, making sure it goes up the sides slightly.

Step 3: Parbake the crust

Bake the crust for 15 minutes until lightly golden around the edges. Remove from oven; the crust will be soft in the center — that’s fine.

Step 4: Make the filling

While the crust bakes, whisk together eggs, corn syrup, brown sugar, melted butter, vanilla, and salt until smooth. Stir in 2 cups of the chopped pecans.

Step 5: Pour and top with pecans

Pour the pecan filling over the parbaked crust. Arrange the remaining 1 cup of pecan halves on top in a single layer for a pretty presentation.

Step 6: Bake until just set

Bake 30-35 minutes until the center wobbles slightly (like jello) when you shake the pan. The edges will be set, the center will jiggle but not slosh. Cool completely on a wire rack — at least 4 hours, ideally overnight. Lift out by parchment, then slice into 24 bars.

Pro tips for the best pecan pie bars

Toast pecans first. 5 min in dry skillet doubles the nutty depth. Lightly toasted halves on top look extra-elegant.
SUB DARK corn syrup for half the light for a deeper molasses note. Old-school Southern style.
Add 2 tbsp bourbon to the filling for grown-up bars. Pairs beautifully with pecans.
Drizzle melted chocolate over cooled bars for chocolate pecan pie bar variation.

Frequently asked questions

Can I freeze them?

Yes — wrap individual bars tightly, freeze up to 3 months. Thaw at room temp 1 hour before eating.

How long do they keep?

5 days at room temp in airtight container, OR 2 weeks refrigerated. Best at room temp for chewy texture.

Can I make them gluten-free?

Sub 1:1 GF flour blend for the crust. Same technique, GF result.

Why is my filling runny?

Underbaked — bake 5 more min. Or didn’t cool long enough — these MUST cool 4+ hours to set the filling.

Can I make them in a smaller pan?

Yes — halve the recipe for an 8×8 pan. Makes 16 smaller bars. Bake 25-30 min.
