Preheat your oven to 350°F (175°C) and prepare your cake pan by greasing it with butter or baking spray and dusting it with flour.

In a medium bowl, whisk together the all-purpose flour, baking powder, and salt.

In a large mixing bowl, beat the softened butter and granulated sugar for 2-3 minutes until pale and fluffy.

Add the eggs one at a time, mixing well after each. Then mix in the vanilla extract.

Gradually add the dry ingredients and wet ingredients, alternating between them, mixing until just combined.

Pour the batter into the prepared cake pan and smooth the top with a spatula.

Bake in the preheated oven for 30-35 minutes until golden and a toothpick comes out clean.

Allow the cake to cool in the pan for about 15 minutes before transferring to a wire rack to cool completely.
