Make the Brownies
- Heat your oven to 350F. Line a 9x13 inch pan with parchment, leaving overhang for easy removal. In a medium saucepan over low heat, melt the butter with 6 oz of the chocolate chips, stirring until smooth. Remove from heat and let cool 5 minutes so you do not scramble the eggs.
- Whisk the sugar into the melted chocolate mixture until glossy. Add the eggs one at a time, whisking well after each, then stir in the vanilla. Fold in the flour, cocoa powder, and salt until just combined. Do not overmix. Spread evenly in the prepared pan.
- Bake 25 to 30 minutes until the top is set and a toothpick inserted in the center comes out with moist crumbs but no wet batter. Sprinkle the remaining 2 oz chocolate chips on top immediately after baking. Let cool completely in the pan on a wire rack, about 1 hour.
Make the Cookie Dough
- Spread the flour for the cookie dough on a baking sheet and bake at 350F for 5 minutes to kill any bacteria. Let cool completely. This step is essential for safe-to-eat raw dough.
- Beat the softened butter with both sugars on medium speed until light and fluffy, about 3 minutes. Mix in the milk and vanilla. Gradually add the cooled heat-treated flour on low speed until a thick dough forms. Fold in the mini chocolate chips.
- Spread the cookie dough evenly over the cooled brownies using an offset spatula or your hands. Press gently to create an even layer. Refrigerate at least 30 minutes to firm up before slicing. Lift out using the parchment overhang and cut into 16 squares.
Notes
To heat-treat flour, spread on a baking sheet and bake at 350F for 5 minutes or until it reaches 165F internally. Let cool completely before using or it will clump in the dough. These keep covered in the refrigerator for up to 5 days and actually taste better on day two as the flavors meld. For clean cuts, run your knife under hot water and wipe dry between slices.
