Preheat the oven to 325°F (160°C). Grease and flour a loaf pan.

In a mixing bowl, beat the cream cheese and butter together until smooth.

Gradually add the sugar and continue to beat until light and fluffy.

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

In a separate bowl, whisk together the flour, baking powder, and salt.

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Pour the batter into the prepared loaf pan and smooth the top.

Bake in the preheated oven for 60-70 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
