Preheat your oven to 350°F (175°C) and grease a 9-inch cake pan, lining the bottom with parchment paper.

In a large mixing bowl, cream the softened unsalted butter and granulated sugar together on medium speed for about 3-5 minutes.

Add the large eggs to the creamed mixture one at a time, beating well after each addition.

Mix in the pure vanilla extract until fully combined.

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this to the wet ingredients.

Slowly pour in your chosen milk or cream while mixing on low speed until the batter is smooth.

Pour the batter into your prepared cake pan, smoothing the top.

Bake in the preheated oven for 40-50 minutes until golden brown and a toothpick comes out clean.

Allow the cake to cool in the pan for 10-15 minutes before transferring it to a wire rack.

Once cool, dust with powdered sugar before serving.
