How to Make It
Preheat oven to 325˚F. In a medium bowl, mix together all-purpose flour, baking soda, and salt.
In large bowl, cream butter and sugar. Add eggs, one at a time, mixing well after each addition. Add half of the flour mixture, followed by the sour cream, and then the other half of the flour mixture, blending well after each addition. Add vanilla extract and mix well. Pour batter into a greased and floured Bundt pan.
Bake for 60 to 90 minutes, until cake springs back when lightly touched and has separated from the sides of the pan. Cool for 20 minutes and then turn cake out on a cake rack.
