Cookies made with nutty brown butter and loaded with gooey chunks of dark chocolate. A perfect balance of crispy edges and soft centers in every bite!
Combine the cooled melted butter with the brown sugar and white sugar. Whisk until it resembles a wet sand. Add the egg, milk, and vanilla. Mix well.
In a small bowl, combine the flour, baking soda, milk powder, and salt. Mix well, then add the dry ingredients to the wet ingredients. Fold the dry ingredients into the wet ingredients using a silicone spatula.
Add the chopped chocolate and mix again.
Cover the bowl and refrigerate for 30 minutes.
After 30 minutes, or once the dough is firm enough, begin forming the dough into balls. (Tip: I like rolling them into a tall ball rather than a perfectly round one.) I used an ice cream scoop with a 40 ml capacity. The weight of each dough ball is 60-62 g. Once all the dough has been used up or formed into balls, place them on a tray that fits in your fridge. Chill for another hour or two. (Note: You can keep the shaped dough in the fridge/freezer for up to 24 hours and bake directly from the fridge/freezer. Bake at the same temperature, but add 2 extra minutes to the baking time. I baked mine for 15 minutes (the 24-hour chilled dough, I mean) – slightly crunchy on the outside and soft on the inside. But keep in mind that ovens vary, so watch your cookies closely.)
Preheat the oven to 350°F. Line baking sheets with parchment paper. Place the cookie dough balls on the prepared baking sheets, leaving about 2 inches between each. Bake for 8-12 minutes (see note above), depending on the texture you want. Don’t forget to rotate the pan halfway through baking if you're using a non-fan oven to ensure even cooking.
Leave the cookies on the pan for 2 minutes before moving to a cooling rack to cool further.
