Grease and flour a 9x5-inch loaf pan and line it with parchment paper for easy removal.
In a stand mixer or a large bowl with electric beaters, cream the softened butter and sugar together until light and fluffy. Be sure to scrape down the sides of the bowl as needed.
Add the eggs one at a time, ensuring each is fully incorporated before adding the next. Again, scrape down the sides of the bowl to get all that butter mixed in.
Mix in the vanilla extract, or paste.
In a separate bowl, whisk together the flour, baking powder, and salt.
Gradually add the dry ingredients to the butter mixture, mixing on low speed. When the flour is almost completely incorporated, add in the sour cream. Mix just until everything is combined. Note: be sure to scrape down the sides and bottom of the bowl.
Turn the batter into the prepared loaf pan, smoothing the top with a spatula.
Bake for approximately 55 to 65 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. For me the bake time was 60 minutes.
Allow the cake to cool in the pan for about 15 minutes, then transfer to a rack. You can enjoy the cake warm, or at room temperature.
Store fully cooled pound cake in an airtight container at room temperature for up to 3 days. It will freeze nicely.
