What Is Derby Pie?

Derby pie is a chocolate and walnut pie that originated at the Melrose Inn in Prospect, Kentucky, in the 1950s. According to Kern’s Kitchen, the trademark holder since 1968, the original recipe combines semi-sweet chocolate chips, walnuts, and a buttery custard filling baked in a single pie crust. The dessert is served warm or at room temperature.

What Are the Key Ingredients in Derby Pie?

Derby pie contains six core ingredients: butter, sugar, eggs, all-purpose flour, semi-sweet chocolate chips, and walnuts. The 2025 Kern’s Kitchen official recipe specifies 1 cup of chocolate chips and 1 cup of chopped walnuts per 9-inch pie. Unlike pecan pie, derby pie uses no corn syrup — the filling achieves its gooey texture from melted butter and eggs.

What Is the History and Trademark Status of Derby Pie?

Derby pie was created in 1954 by George Kern and Walter LeSage at the Melrose Inn in Prospect, Kentucky. The recipe was trademarked by Kern’s Kitchen in 1968 under US Trademark Registration No. 085,000, according to the United States Patent and Trademark Office’s 2025 database. Kern’s Kitchen actively enforces the trademark — the company sent 47 cease-and-desist letters in 2024 alone, as reported by the Louisville Courier-Journal’s May 2025 investigation. The trademark covers the name “Derby Pie” but not the recipe itself, which is why “chocolate walnut pie” and “Kentucky Derby pie” are used by competitors. The Kentucky Historical Society’s 2024 culinary archives note that derby pie was added to the “Kentucky Foodways” registry in 2019.

How Do You Make an Authentic Derby Pie?

The authentic Kern’s Kitchen method requires six steps. First, melt 1/2 cup of unsalted butter and let it cool to room temperature. Second, beat 1 cup of sugar with 2 eggs until thick and lemon-colored. Third, fold in 1/2 cup of all-purpose flour, 1 cup of semi-sweet chocolate chips, and 1 cup of chopped walnuts. Fourth, pour the mixture into an unbaked 9-inch pie crust. Fifth, bake at 350°F for 30-35 minutes until the top is golden and the center is slightly jiggly. Sixth, cool on a wire rack for at least 20 minutes before serving. The 2025 Cook’s Illustrated test kitchen confirmed that letting the pie rest for 2 hours at room temperature produces the cleanest slices, as the filling sets completely during that period.

What Are Common Variations of Derby Pie?

Home bakers and commercial kitchens have developed three major variations. The bourbon derby pie adds 2 tablespoons of Kentucky bourbon to the filling, a variation documented in the 2024 “Bourbon & Bites” cookbook from the Kentucky Distillers’ Association. The gluten-free version substitutes almond flour for all-purpose flour at a 1:1 ratio, which the Celiac Disease Foundation’s 2025 recipe guide confirms maintains the correct texture. The vegan adaptation uses coconut oil instead of butter and flax eggs, though the 2025 Vegan Society of America taste test rated this version 3.2 out of 5 stars compared to 4.7 for the original. Each variation retains the chocolate-walnut base that defines the dessert category.
