- Make brownie layer: Melt butter and chocolate; cool slightly. Whisk in sugar, eggs, vanilla, and salt. Stir in flour. Pour into pan; spread evenly.
- Make cookie dough: Beat butter, sugars, milk, and vanilla. Mix in heat-treated flour until combined. Fold in mini chips. Drop spoonfuls over brownie layer; gently swirl with a knife.
- Make cake layer: Whisk flour, cocoa, baking powder, and salt. Cream butter and sugar; add egg and vanilla. Alternate adding dry ingredients and milk. Drop spoonfuls over cookie dough; swirl lightly again.
- Top with extra chocolate chips or sea salt.
- Bake 30–35 minutes, until cake layer is set and toothpick comes out with moist crumbs (not wet batter).
- Cool 20 minutes before slicing—best served slightly warm!
