Ingredient highlights
- Cocoa powder: Gives the brownie filling its rich chocolate flavour. Use unsweetened cocoa powder for best results.
- Cornflour or cornstarch: Helps create soft, thick cookies with a tender texture.
- Partially melted butter: Creates chewy cookies while keeping the dough easy to work with.
- Chocolate chips: Add extra chocolate flavour and pockets of melted chocolate throughout the cookies.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements. Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
