Preheat your oven to 350°F (175°C). Line and grease a springform pan.

In a mixing bowl, beat together the butter, brown sugar, and granulated sugar until pale and fluffy.

Add the eggs one at a time, mixing well after each addition, then add the vanilla extract.

In a separate bowl, whisk together flour, baking soda, and salt. Gradually mix this into the wet ingredients until just combined.

Fold in the chocolate chips gently with a spatula.

Pour the batter into the prepared springform pan and spread it evenly.

Bake for 25-30 minutes until edges are set but center may seem underbaked.

Let the cake cool in the pan for 15 minutes, then remove from the pan. Frost if desired.
