Step 1: Preheat your oven to 325°F (165°C). Grease and flour a 10-inch tube pan or Bundt pan thoroughly.
Step 2: In a large bowl, cream together the softened butter and cream cheese until smooth and well-combined.
Step 3: Gradually add the granulated sugar to the butter mixture, beating at medium-high speed for 5-7 minutes until the mixture is light and fluffy.
Step 4: Add the eggs one at a time, beating well after each addition and scraping down the sides of the bowl to ensure even mixing.
Step 5: Stir in the vanilla extract and salt.
Step 6: Turn the mixer to low speed and gradually add the sifted flour, mixing just until combined. Do not overmix.
Step 7: Pour the batter into the prepared pan and smooth the top with a spatula.
Step 8: Bake for 75 to 90 minutes, or until a wooden skewer inserted into the center comes out clean.
Step 9: Allow the cake to cool in the pan for 15-20 minutes before inverting it onto a wire rack to cool completely.
