Brownie Pecan Pie Bars

Two Southern classics collide in one pan. A cocoa-laced brownie layer goes down first, dense and fudgy from melted butter and a generous hit of cocoa powder. While that bakes, you build the topping: a pecan pie filling loaded with chopped pecans, eggs, and butter that pours right over the warm brownie base.

The double bake is what makes these bars work. The brownie layer sets up first so it can support that sticky, caramelized topping without turning to mush. When the topping firms up in that second round, you get a clean slice with two distinct layers.

Let them cool completely before cutting. Patience is tough here, but warm bars will crumble and stick to the knife.

Pro Tips

• Use natural cocoa powder, not Dutch-process, for the deepest chocolate flavor against all that sugar.
• Line the pan with parchment and leave an overhang so you can lift the whole slab out for cleaner cuts.
• Pour the pecan topping immediately after mixing. If it sits too long, the sugar starts to set and it won’t spread evenly.
• These bars get better overnight as the layers meld together. Store covered at room temperature.

Variations

• Add a pinch of flaky sea salt over the topping before the second bake for a sweet-salty finish.
• Swap pecans for walnuts if that’s what you have on hand.
