Bourbon Pecan Pie Bars with Buttery Shortbread Crust
These bourbon pecan pie bars combine a crisp, buttery shortbread base with a rich, custard-like filling studded with toasted pecans and spiked with bourbon. The bars deliver the classic pecan pie experience in portable, shareable form, with caramelized corn syrup binding eggs and brown sugar into a glossy topping that sets just enough to slice cleanly. The vanilla and bourbon add warmth and depth without overpowering, while toasting the pecans beforehand boosts their nutty flavor. These bars suit dessert tables, holiday gatherings, and anyone craving a sophisticated, boozy treat that feels homemade and special. Unlike traditional pecan pie, the shortbread base stays crisp thanks to blind baking, and the bar format makes serving effortless. This version balances sweetness with bourbon's subtle char and the pecans' natural earthiness, delivering complexity in every bite.

Tips
Toast pecans just until fragrant and lightly browned to enhance their natural oils and flavor without bitterness. Over-toasting turns them acrid; stop when you first smell them and they begin changing color.
Blind bake the crust to ensure a crisp, dry base that won't become soggy from the wet filling. Parchment and weights prevent puffing and keep edges from browning too fast.
Don't overfill the bars with the egg mixture. Pour only until liquid reaches the crust edge; excess filling takes longer to set and may spill over edges during baking.
Good to Know
Keep in an airtight container at room temperature for up to 5 days, or refrigerate for up to 1 week. The crust softens slightly when chilled; let bars sit at room temperature 10 minutes before serving for best texture.
Dough can be rolled and chilled up to 24 hours before blind baking. Baked bars can be made up to 2 days ahead; store covered. Do not freeze after filling, as the custard texture breaks down; freeze unfilled, blind-baked crust only.
Serve at room temperature with coffee, bourbon, or vanilla ice cream. Pair with after-dinner drinks. Cut into 2-inch squares for dessert platters or smaller 1-inch pieces for bite-sized portions.
Common Mistakes
Overprocess the dough to avoid developing gluten, which makes the crust tough rather than tender.
Skip blind baking to avoid a soggy, underbaked crust that doesn't hold up to the wet filling.
Overfill with custard mixture to avoid spilling and uneven baking across the pan.

FAQ
Can I make these bars ahead and freeze them?
Yes, freeze the blind-baked, unfilled crust up to 3 months. Thaw at room temperature, then fill and bake as directed. Do not freeze after filling, as the custard layer breaks down and becomes grainy when thawed.
What if I don't have bourbon?
Substitute brandy, dark rum, or even skipped entirely without replacing. The filling will be slightly less complex but still delicious. Brandy keeps the flavor subtle; rum adds warm spice notes that pair well with pecans.
How long do baked bars keep at room temperature?
Keep bars in an airtight container at room temperature for up to 5 days. They soften slightly over time as the crust absorbs moisture from the filling. Refrigerate for longer storage up to 1 week; let them sit at room temp 10 minutes before serving.
