Derby Pie Bars

I’m not a huge pie person. I know, I know. But bars?? Bars are a different story. You get that perfect edge-to-edge ratio of crust to filling in every single bite, and I am fully HERE for it.

These Derby Pie Bars take a Kentucky classic and turn it into a shareable situation. Buttery shortbread crust, a gooey bourbon chocolate filling studded with walnuts, and a scoop of vanilla bean ice cream melting all over the top. The whole kitchen smells ridiculous while they bake.

I brought a pan to book club last week and they were GONE before I could snag seconds. Lesson learned: always make two.

What Is Derby Pie?

Derby Pie is a trademarked Kentucky classic born in 1954 at the Melrose Inn near Louisville. The exact recipe is famously SECRET (legally protected), but the concept is universally adored: a buttery crust loaded with chocolate, walnuts, and bourbon in a custardy filling.

These bars CAPTURE that iconic flavor in a portable square that cuts cleanly and serves a crowd. Served warm with melting vanilla bean ice cream, the result is rich, fudgy, and unapologetically decadent.

The bourbon matters HERE. Cheap whiskey will leave your bars tasting flat and harsh, so reach for something mid-range like Bulleit, Woodford Reserve, or Maker’s Mark. Smooth enough to sip means smooth enough to bake with!

How to Get Clean, Fudgy Bars

Step 1: Pull the bars when the center is still JIGGLY. Slightly underbaked means fudgy, not cakey (this is non-negotiable).

Step 2: Cool in the pan for 30 minutes at room temperature. Patience equals clean cuts, not crumble.

Step 3: Dip a sharp knife in hot water, wipe dry, slice. Repeat between every cut.

Hot blade, steady hand, oven door discipline. Done. Bakery-worthy squares await.

Can You Skip the Bourbon?

  1. Omit it completely…. the bars stay rich and fudgy, just sans that signature KENTUCKY kick.
  2. Swap in dark rum (same 1/4 cup) for sweeter molasses notes that pair naturally with chocolate.
  3. Use 2 tablespoons vanilla extract plus 2 tablespoons water for a kid-friendly version that keeps moisture.
  4. Try apple juice or cold brewed coffee (same 1/4 cup) for subtle background complexity, ZERO alcohol needed.
  5. A tablespoon of bourbon extract works if you want flavor without the liquid content.

Walnuts vs. Pecans in Derby Pie

  • TRADITIONAL Derby Pie uses WALNUTS….their earthy, slightly bitter bite balances all that sugar and bourbon.
  • PECANS are a fair swap but push the bar sweeter and more praline-leaning.
  • Chop nuts to about 1/4-inch pieces (not powder-fine) so they spread evenly and don’t sink.
  • Toasting at 325°F for 8 minutes deepens the flavor….optional but worth it.
  • Smell your nuts first….rancid stock will sabotage the whole pan.

Whichever nut wins, just don’t leave them out entirely….that fudgy filling needs something to bite back.

How to Store Derby Pie Bars

Store these bars in an AIRTIGHT container at room temperature for up to 3 days….the crust stays surprisingly tender this way (no refrigeration needed unless your kitchen runs warm).

For longer keeping, refrigerate up to one week, or freeze individual squares wrapped tightly in plastic wrap, then foil, for up to 3 months. Thaw overnight in the fridge before serving, and warm briefly if you want that gooey, just-baked feel.

  • Carbohydrates: 470-500 g

Ingredients

For the crust:

  • 1/3 cup powdered sugar
  • 1 1/4 cups all-purpose flour
  • 1/4 teaspoon salt
  • 1/2 cup cold butter, cut into 1/2-inch cubes

For the filling:

  • 12 tablespoons butter, melted and cooled
  • 1 1/2 cups granulated sugar
  • 3 large eggs
  • 3/4 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 cup quality bourbon
  • 2 teaspoons vanilla extract
  • 1 1/2 cups semi-sweet chocolate chips
  • 1 1/2 cups chopped walnuts

For serving:

  • Vanilla bean ice cream

Step 1: Mix the Shortbread Crust

  • 1/3 cup powdered sugar
  • 1 1/4 cups all-purpose flour
  • 1/4 teaspoon salt
  • 1/2 cup cold butter, cut into 1/2-inch cubes

Preheat your oven to 350°F.

In a bowl, combine the powdered sugar, flour, and salt.

Add the cold butter cubes and use your fingertips or a pastry cutter to work the mixture until it resembles coarse breadcrumbs with pea-sized pieces of butter still visible—this texture is crucial for a tender, flaky crust.

Press this mixture firmly and evenly into a 9×13 inch baking dish, working it up slightly along the sides.

Bake for 20-23 minutes until the edges are just beginning to turn light golden brown.

The crust should be set but not fully browned since it will bake again with the filling.

Step 2: Whisk the Bourbon Filling

  • 12 tablespoons butter, melted and cooled
  • 1 1/2 cups granulated sugar
  • 3 large eggs
  • 3/4 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 cup quality bourbon
  • 2 teaspoons vanilla extract
  • 1 1/2 cups semi-sweet chocolate chips
  • 1 1/2 cups chopped walnuts

While the crust bakes, whisk together the melted and cooled butter with the granulated sugar in a large bowl until well combined.

Add the eggs one at a time, whisking well after each addition to create a smooth base.

In a separate small bowl, whisk together the flour and salt.

Fold the dry mixture into the butter mixture gently until just combined.

Stir in the bourbon and vanilla extract—I love using quality bourbon here as it adds an authentic Kentucky character to these bars.

Finally, fold in the chocolate chips and walnuts, being careful not to overmix.

Step 3: Bake Until Just Set

  • Pre-baked crust from Step 1
  • Filling mixture from Step 2

Remove the pre-baked crust from the oven and let it cool for just 2-3 minutes.

Pour the filling from Step 2 evenly over the warm crust, spreading it gently to the edges.

Return to the oven and bake for 25 minutes until the filling is set but still slightly jiggly in the very center—it should not be completely firm.

I find that slightly underbaking these bars keeps them fudgy and rich, which is exactly what you want for a Derby Pie.

Step 4: Cool and Slice Cleanly

Remove the bars from the oven and let them cool in the pan for at least 30 minutes at room temperature.

This cooling time allows the filling to set properly so the bars will cut cleanly without falling apart.

Once cooled, use a sharp knife dipped in hot water (and wiped dry between cuts) to cut the bars into uniform squares.

Step 5: Top with Vanilla Ice Cream

  • Vanilla bean ice cream

Serve the Derby Pie bars warm or at room temperature with a generous scoop of vanilla bean ice cream on top.

The melting ice cream creates a luxurious contrast with the warm, fudgy bars.
