Preheat oven to 350°F (175°C). Grease and flour a 9x5 inch loaf pan.
In a medium bowl, whisk together flour, sugar, baking powder, and salt.
In a large bowl, cream together butter and sugar until light and fluffy. Beat in eggs one at a time, then stir in vanilla.
Gradually add the dry ingredients to the wet ingredients, alternating with the whipped cream, beginning and ending with the dry ingredients. Mix until just combined.
Pour batter into prepared pan and bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean.
Let cool in pan for 10 minutes before inverting onto a wire rack to cool completely.
