Pecan pie bar ingredients
- Yellow cake mix: Any boxed yellow cake mix will work as the base for the crust.
- Butter: Salted or unsalted, melted for the crust.
- Eggs: Used in both the crust and the pecan filling.
- Corn syrup and brown sugar: Light corn syrup and light or dark brown sugar create the classic pecan pie sweetness and texture.
- Vanilla extract: Adds depth and enhances the filling’s flavor.
- Pecans: Chopped or roughly chopped for texture—reserve larger pieces if you like more crunch.
How to make pecan pie bars with a cake mix
Bottom crust. Preheat the oven to 350°F. Combine one box of yellow cake mix with one egg and one stick (½ cup) of melted butter. Press the mixture firmly into the bottom of a lightly greased 9″ x 13″ baking dish. Bake the crust for 20 minutes, then remove and set aside while you prepare the filling.

Pecan filling. In a bowl, whisk together 1½ cups light corn syrup, ⅓ cup brown sugar, 3 large eggs, and 1 teaspoon vanilla until smooth. Stir in 1½ cups chopped pecans. Pour the filling evenly over the pre-baked crust and return the pan to the oven.

Bake and cool. Bake for 40–45 minutes, or until the filling is set and the edges are lightly browned. When you remove the pan from the oven, run a sharp knife around the edges to loosen the bars—the filling will be sticky. Allow the bars to cool completely in the pan before cutting into squares to ensure clean slices.
