Ingredients
  

For Browning:
  • 1 ½ cups 340g salted butter
Base Dough (Shared):
  • 1 ½ cups 300g granulated sugar
  • 3 teaspoons vanilla extract
  • 2 large eggs room temperature
  • 1 ½ teaspoons baking powder
  • 1 ½ teaspoons baking soda
  • 1 teaspoon salt
For the Chocolate Chip Cookie Dough:
  • 2 cups +2 tbps 270g all-purpose flour (spooned and leveled)
  • 1 cup 175g semi-sweet chocolate chips
For the Double Chocolate Brownie Dough:
  • 2 cups 250g all-purpose flour (spooned and leveled)
  • ⅓ cup 28g unsweetened cocoa powder
  • 1 cup 175g semi-sweet chocolate chunks

Equipment

  • 1 Light-colored saucepan for browning butter
  • 1 Kitchen scale (optional but helpful for dividing dough)
  • 1 Stand mixer or hand mixer with large bowl
  • 1 Large and medium mixing bowls
  • 1 Whisk
  • 1 Rubber Spatula
  • 1 ¼ cup cookie scoop or dry measuring cup
  • 1 Baking sheets
  • 1 Parchment paper or silpat liners
  • 1 Wire Cooling Rack

Method
 

  1. Brown the butter: Place salted butter in a light-colored saucepan over medium heat. Melt completely, then continue cooking until it foams, the foam subsides, and golden brown specks appear at the bottom. The butter will smell nutty and toasty. Immediately remove from heat and pour into a large heat-safe bowl. Cool for 15-20 minutes.
  2. Mix base wet ingredients: To the cooled brown butter, add granulated sugar. Beat until creamy and combined, about 2-3 minutes. Add vanilla extract and eggs. Mix until smooth and glossy.
  3. Add base dry ingredients: Add baking powder, baking soda, and salt. Mix until combined.
  4. Divide the dough: Divide the dough into two equal halves. A kitchen scale is best for accuracy. Place one half in a separate bowl and set aside.
  5. Make chocolate chip dough: To the dough still in the mixer, add 2 cups + 2 tablespoons all-purpose flour. Mix until just combined. Fold in 1 cup semi-sweet chocolate chips. Transfer this dough to a plate and set aside.
  6. Make double chocolate dough: Place the reserved other half of dough back into the mixer bowl. Add 2 cups all-purpose flour and ⅓ cup unsweetened cocoa powder. Mix until fully combined. Fold in 1 cup semi-sweet chocolate chunks.
  7. Preheat and prep: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silpat liners.
  8. Assemble cookies: Using a ¼ cup scoop, take one portion of chocolate chip dough and one portion of double chocolate dough. Press them together to form one large dough ball. For a marbled look, break each portion in half, rotate, and press back together. Place on prepared baking sheets, 3 inches apart.
  9. Chill (if needed): If your kitchen is warm or dough feels soft, refrigerate assembled dough balls for 20-30 minutes before baking.
  10. Bake: Bake for 12-14 minutes, until edges are barely golden brown and set. Centers will still look soft.
  11. Cool: Let cookies cool on baking sheets for 10-15 minutes before transferring to a wire rack. Serve warm or at room temperature.

Notes

  1. Use a Kitchen Scale for Dough Division: Dividing the dough evenly is crucial for consistent cookies. Weigh the total dough and divide exactly in half for best results.
  2. The Extra 2 Tablespoons of Flour Matters: That small amount in the chocolate chip dough balances the spread between the two doughs. Do not skip it!
  3. Chill If Your Kitchen is Warm: If your dough feels soft or your kitchen is warm, refrigerate the assembled dough balls for 20-30 minutes before baking. This prevents excessive spreading.
  4. Do Not Overbake: Pull the cookies out when edges are just set and centers still look soft. They will continue baking on the hot sheet. Overbaking leads to dry cookies.
  5. Salted Butter is Intentional: This recipe uses salted butter to balance the sweetness. If using unsalted, add 1 teaspoon of salt instead of the 1 teaspoon listed.
  6. Room Temperature Eggs: For best mixing, ensure your eggs are at room temperature. Cold eggs can cause the brown butter to seize.
  7. Storage: Store in an airtight container at room temperature for up to 5 days. Add a slice of bread to keep cookies soft.
  8. Freezer Option: Freeze assembled, unbaked dough balls for up to 3 months. Bake from frozen at 350°F for 14-16 minutes.
