The secret? Lemon juice.
¼ teaspoon of freshly squeezed lemon juice is mixed into the dough, helping create the distinctive flavor and texture that have made the DoubleTree chocolate chip cookie a beloved part of the travel experience. The ingredient may seem unexpected, but it plays a small, but important, role in the recipe’s well-known flavor.
It remained one of the cookie’s best-kept secrets for years until DoubleTree by Hilton publicly released the official recipe in 2020, surprising home bakers everywhere. Along with classic ingredients like butter, brown sugar, rolled oats and walnuts, the recipe revealed the unexpected addition that had many cookie enthusiasts doing a Double(Tree) take. See the full recipe at the link below.
“Guests are always intrigued when they learn freshly squeezed lemon juice is part of the DoubleTree by Hilton chocolate chip cookie recipe,” said Drew Iddings, global brand leader, DoubleTree by Hilton. “It’s a small ingredient, but it’s become one of the most talked-about details when we unveiled the recipe behind the famous cookie that has welcomed guests for decades.”
