Preheat the oven to 180°C (356°F) fan.
Place your flour in an even layer on a lined sheet pan and bake for 8-10 minutes.
Gather the flour in a mound and measure the temperature. It just needs to be over 71°C (165°F).
Allow the flour to cool to room temperature.
Melt the butter and let it cool, too.
Whisk the cooled melted butter, dark brown sugar, and cane sugar for one minute in a medium bowl. I do this by hand but you can use a mixer.
Add milk, sea salt, vanilla, and flour until combined.
Fold in the chocolate chips.
Measure out the dough into 10 gram balls for a uniform size.
Place the balls in the freezer while you melt the dark chocolate.
