Preheat oven to 325°F and grease a bundt pan. Cream butter and sugar until fluffy. Add eggs one at a time, then vanilla. Mix flour and salt separately. Add dry ingredients alternately with sour cream. Fold in pineapple and strawberries. Bake 75–85 minutes until set. Cool before slicing.
Notes
Drain fruit well to avoid excess moisture. Do not overmix batter.
