DoubleTree by Hilton chocolate chip cookie at hotel front desk
DoubleTree by Hilton’s signature chocolate chip cookie welcomes guests at the front desk.

To celebrate the National Chocolate Chip Cookie Day, DoubleTree by Hilton is once again inviting travelers and local community members to stop by any DoubleTree by Hilton hotel in the U.S. on August 4 for a complimentary chocolate chip cookie. No reservation is required.

For decades, the cookie’s soft texture, rolled oats and abundance of chocolate chips have earned it a loyal following. However, one ingredient often surprises even the biggest fans.

The secret? Lemon juice.

Just ¼ teaspoon of freshly squeezed lemon juice is mixed into the dough. The unexpected ingredient helps create the distinctive flavor and texture that have made the DoubleTree chocolate chip cookie a beloved part of the travel experience.

Although it may seem surprising, lemon juice plays a small but important role in the cookie’s signature flavor. The ingredient remained one of the recipe’s best-kept secrets for years.

That changed in 2020, when DoubleTree by Hilton publicly released the cookie recipe. The reveal surprised home bakers everywhere. Along with classic ingredients such as butter, brown sugar, rolled oats and walnuts, the recipe revealed the unexpected addition that had cookie enthusiasts doing a Double(Tree) take.

“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.”
