Ingredients
Method
- Beat the butter, granulated sugar, and brown sugar with an electric mixer on medium speed for 2 minutes until light and fluffy.
- Add the vanilla extract and milk, then beat on low for 30 seconds until combined.
- Fold in the heat-treated flour and salt by hand until no dry flour remains, about 1 minute, then fold in the chocolate chips.
- Press the dough firmly into an 8×8-inch parchment-lined pan and refrigerate for at least 1 hour.
- Lift the chilled block out of the pan, cut into 16 squares, and serve cold.
Notes
The 1 hour chilling time is not included in the prep or total time. For the cleanest slices, warm your knife under hot water, wipe it dry, and cut while the bars are still cold.
