Pecan Pie Bars Recipe: Buttery Shortbread Squares

Pecan Pie Bars are chewy, nutty bars made quickly with a yellow cake mix. They combine a simple buttery crust with a gooey pecan topping for a dessert that feels homemade but comes together in far less time than a traditional pecan pie. These bars travel well, slice cleanly when fully cooled, and are perfect for potlucks, holiday gatherings, or an easy weeknight treat.

This recipe uses a boxed yellow cake mix for the base, making it a reliable semi-homemade option when you need a great dessert fast. The filling is the familiar combination of corn syrup, brown sugar and eggs, folded together with vanilla and pecans for that classic pecan pie flavor in bar form.

Pecan pie bar ingredients

• Yellow cake mix: Any boxed yellow cake mix will work as the crust base.
• Butter: Use salted or unsalted; melted for easy mixing.
• Eggs: One for the crust and three for the pecan topping.
• Corn syrup and brown sugar: Light or dark corn syrup is fine; brown sugar adds depth.
• Vanilla extract: Enhances the sweetness and overall flavor.
• Pecans: Chopped or left larger for texture, depending on preference.

How to make pecan pie bars with a cake mix

Prepare the crust: Preheat your oven to 350°F (175°C) and lightly grease a 9″ x 13″ baking dish. In a bowl combine 1 box yellow cake mix, 1 egg and 1 stick (½ cup) melted butter until the mixture forms a cohesive dough. Press this evenly into the bottom of the prepared pan. Bake the crust for 20 minutes, then remove it from the oven and set aside while you make the filling.

Make the pecan topping: In a medium bowl whisk together 1 1/2 cups light corn syrup, 1/3 cup light brown sugar, 3 large eggs and 1 teaspoon vanilla until smooth. Stir in 1 1/2 cups chopped pecans. Pour the mixture evenly over the baked crust.

Bake and cool: Return the pan to the oven and bake for 40–45 minutes, or until the filling is set and edges are bubbling slightly. When the baking time is complete, remove the pan and run a sharp knife around the inside edges to loosen the bars from the dish — the filling will be sticky. Allow the bars to cool completely in the pan before slicing into squares so the filling firms up and the slices hold together.

How to store

• To store: Wrap individual bars tightly in plastic wrap or place them in an airtight container. Keep refrigerated for up to 4 days.
• To freeze: Wrap each bar in plastic wrap and place in a freezer-safe bag or container. Freeze for up to 3 months. Thaw in the refrigerator overnight before serving.
