Preheat the oven to 180°C. Grease a 9-inch round cake pan and line it with parchment paper.
In a large mixing bowl, combine 200 grams of all-purpose flour, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and a pinch of salt. Mix well.
In another bowl, whisk together 200 grams of sugar, 100 grams of softened unsalted butter, and 1 teaspoon of vanilla essence until creamy.
Add 2 large eggs, one at a time, to the sugar-butter mixture, whisking well after each addition.
Gradually add the dry ingredients to the wet ingredients, alternating with 200 ml of milk, starting and ending with the dry ingredients. Mix until just combined.
Fold in 150 grams of chocolate chips into the batter.
Pour the batter into the prepared cake pan and spread it evenly.
Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
