Preheat the oven to 325 degrees F (165 degrees C). Grease and flour a 10-inch bundt pan.
Cream butter and cream cheese together in a mixing bowl until smooth. Gradually add sugar and beat until fluffy.
Add eggs, two at a time, beating well with each addition. Add flour all at once and mix in. Mix in vanilla. Pour batter into the prepared cake pan.
Bake in the preheated oven for 1 hour and 20 minutes, checking for doneness at 1 hour. A toothpick inserted into the center of the cake should come out clean. Remove and cool before serving.
