Brown the butter

• Melt the butter in a saucepan and cook until browned and nutty.

Whisk the sugars with the warm butter

• While the butter is still very warm, pour it directly over the brown sugar and granulated sugar.
• Whisk until smooth and glossy.

Cool slightly

• Let the mixture cool for a minute or two so it isn't hot enough to cook the egg.

Add egg and vanilla

• Whisk in the egg and vanilla until fully combined.

Fold in the dry ingredients

• Fold in the flour, baking soda and salt until just combined.
• Fold in the chocolate chips.

Shape the cookies

• Scoop the dough and shape each cookie into a ball.
• Space them well apart on the tray, as they spread a lot.

Bake

• Bake at 375°F until the edges are golden and the centers are just set.

Serve

• Serve the cookies warm over ice cream.
