Preheat the oven

• Preheat the oven to 180 °C (350 °F).
• Line a baking tray with baking paper.

Mix the dry ingredients

• In a bowl, whisk together the flour, baking soda and salt.
• Set aside.

Combine the wet ingredients

• In a separate bowl, combine the melted butter, brown sugar and granulated sugar.
• Crack in the egg and add the vanilla extract.
• Whisk until fully combined.

Make the dough

• Gradually pour the dry mixture into the wet mixture.
• Gently fold until just combined.
• Add the chocolate chips and fold in without overmixing.

Shape the cookies

• Scoop out the dough into cookies onto the prepared baking tray.
• Leave about 5 cm between each cookie.

Bake

• Bake until golden brown and crispy on the edges; the middle should still look slightly underbaked.
• They will set once out of the oven.

Reshape if needed

• If the cookies spread too much or merged, use a cookie cutter or a mug to reshape them while still warm.

Cool completely

• Let the cookies cool completely before removing them from the tray so they don't fall apart.
