Ingredients
Butter Mixture
- 1 cup unsalted butter
- 1 ¼ cups light brown sugar (packed)
- ½ cup granulated sugar
Wet Ingredients
- 2 large eggs (room temperature)
- 1 teaspoon vanilla bean paste
Dry Ingredients
- 2 cups all-purpose flour
- 1 cup old-fashioned oats
- ½ teaspoon baking soda
- 1 teaspoon kosher salt
Mix-ins
- 1 cup white chocolate chips
- 1 cup semi-sweet chocolate chips
Instructions
- Browning the Butter: Add the unsalted butter to a medium saucepan and cook over medium-low heat. Stir constantly, scraping the bottom of the pan until small brown bits form, about 6–8 minutes. Remove the pan from heat immediately to prevent burning.
- Mix Sugars into Butter: Stir the light brown sugar and granulated sugar directly into the warm browned butter until smooth and fully combined.
- Chill the Mixture: Transfer the butter and sugar mixture to the refrigerator for about 10 minutes to cool slightly and thicken.
- Prepare for Baking: Preheat the oven to 325°F (163°C). Line two baking sheets with parchment paper and set aside.
- Add Eggs and Vanilla: Remove the butter mixture from the fridge. Beat in the eggs one at a time, then add the vanilla bean paste, stirring until the mixture is smooth.
- Add Dry Ingredients: Add the all-purpose flour, old-fashioned oats, baking soda, and kosher salt to the bowl. Mix gently just until the dough forms and no dry flour remains.
- Incorporate Chocolate Chips: Fold in the white chocolate chips and semi-sweet chocolate chips by hand until evenly distributed through the dough.
- Shape the Cookies: Use a 2-tablespoon cookie scoop to portion the dough onto the prepared baking sheets. Leave about 2 inches between each cookie. Lightly press each dough ball down for even baking.
- Bake the Cookies: Bake for 11–13 minutes, until edges are lightly golden but centers remain soft. Be careful not to overbake to maintain the chewy texture.
- Cool: Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
Notes
- Using browned butter enhances the flavor with a rich, nutty note—do not skip this step for best results.
- Room temperature eggs improve dough consistency and help achieve a tender texture.
- If you prefer a crispier cookie, bake for the full 13 minutes; for softer centers, aim closer to 11 minutes.
- Store cookies in an airtight container at room temperature for up to 5 days or freeze for longer storage.
- Old-fashioned oats add chewy texture; quick oats can be substituted but may change cookie texture slightly.
