Brown the butter

• Melt the butter in a saucepan over medium heat.
• Cook until lightly browned and fragrant, then let it cool slightly.

Make the cookie dough

• Cream the browned butter with the brown sugar and granulated sugar until fluffy.
• Beat in the egg until well combined.
• Stir in the flour and baking powder until just mixed, then fold in the chocolate chips.

Shape the fries

• Turn the dough out onto parchment paper and shape or roll it into a rectangle about ½ inch thick.
• Slice into thin sticks the size of French fries.

Chill the fries

• Place the shaped fries in the freezer (or fridge) so they keep their shape and spread less.

Bake

• Preheat the oven to 175 °C.
• Arrange the chilled cookie fries on a baking tray lined with parchment paper.
• Bake until the edges are lightly golden but the centers stay soft.

Cool and serve

• Let the fries cool slightly; they firm up as they rest.
• Serve warm with a dipping sauce such as Nutella, caramel or strawberry jam.
