James Dunn and Edward Parsons combined parts of their surnames to name the restaurant they opened at the original Farmer’s Market in Los Angeles, California, in 1938. The eatery served a variety of diner foods, including sandwiches, burgers, and pies, but it’s the huge buttery pancakes that made the restaurant so iconic. Many who have tried these say they’re the best pancakes they’ve ever tasted. And yet, nobody has cracked the secret of the 88-year-old recipe. Until now.

There are enough rumors about the recipe to drive a food hacker crazy. Some suggest the batter takes hours to make, while others say the dry ingredients are pre-mixed in secret and cooks simply add buttermilk. Some claims suggest the recipe requires a special flour, while others say it’s just all-purpose flour. When I asked a server about the recipe, she claimed she couldn’t offer any information, or she would get fired and I would go to jail. Yes, she really said that.

But according to my tests with several batches, the recipe requires two major tweaks to an ordinary pancake recipe to make these “legendary.” For my Du-Par’s Legendary Buttermilk Hotcakes copycat recipe, I increased the number of eggs typically used in pancake batter to re-create the custardy texture of the original. The second big secret is butter. The most notable step that makes Du-Par’s pancakes special is the clarified butter generously ladled over the top before serving.

The steps are simple, the recipe is easy, and the pancakes are incredible. This is one you need to try.
