Preheat the oven to 325°F. Grease and flour a tube pan or Bundt pan.
Beat the butter and sugar in the bowl of a heavy duty stand mixture until light and fluffy.
Add the eggs, one at a time, beating until the yellow disappears after each addition.
Whisk together the flour, baking soda, and salt in a medium bowl. Add to the butter mixture, beating until smooth. Mix in the sour cream and vanilla bean paste.
Pour the batter into the prepared tube pan. Bang the pan a couple of times on the work surface to remove any air bubbles from the batter. Bake for 1 hour and 5 minutes to 1 hour and 10 minutes or until a toothpick inserted in the middle of the cake comes out clean.
Cool in the pan for 15 minutes then run a knife around the edges of the pan to loosen the cake. Turn the pound cake out onto a wire rack to cool completely.
Cut into slices and serve with whipped cream and strawberries, if desired.
