Ingredients:
- ½ cup (113g) unsalted butter, softened
- ½ cup (100g) granulated sugar
- ¼ cup (50g) packed light brown sugar
- 1 teaspoon pure vanilla extract
- ¼ teaspoon salt
- 1 cup (120g) all-purpose flour, heat-treated
- ¼ cup (60ml) milk
- ½ cup (85g) semi-sweet chocolate chips
- ½ cup (113g) unsalted butter, melted
- 1 cup (200g) granulated sugar
- ¾ cup (75g) unsweetened cocoa powder
- ¼ teaspoon salt
- 1 teaspoon pure vanilla extract
- 2 large eggs
- ½ cup (60g) all-purpose flour
- Optional: ½ cup (85g) semi-sweet chocolate chips
Instructions:
- Heat-treat the flour: Spread flour on a baking sheet and bake at 350°F (175°C) for 5-7 minutes, ensuring it reaches 165°F (74°C) to kill bacteria. Cool completely.
- Cream together softened butter, granulated sugar, and brown sugar until light and fluffy.
- Beat in vanilla extract and salt.
- Gradually add the heat-treated flour, alternating with milk, until just combined. Don't overmix.
- Stir in chocolate chips.
- Cover and chill in the refrigerator for at least 30 minutes.
- Preheat oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper or foil, leaving an overhang for easy removal.
- In a large bowl, whisk together melted butter, sugar, cocoa powder, and salt until well combined.
- Stir in vanilla extract.
- Add eggs one at a time, mixing well after each addition.
- Gradually add the flour, mixing until just combined. Don't overmix.
- Optional: Stir in chocolate chips.
- Pour brownie batter into the prepared baking pan and spread evenly.
- Drop spoonfuls of chilled cookie dough evenly over the brownie batter.
- Use a knife or toothpick to swirl the cookie dough into the brownie batter.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached (not completely clean).
- Let the brownies cool completely in the pan before lifting them out using the parchment paper or foil overhang.
- Cut into 16 squares and serve.
