Spray a 10-inch bundt or tube pan with non-stick spray or flour and grease pan, whichever you prefer. I recommend this tube pan or this bundt pan. *If you have a 2-piece, 10-inch tube pan, wrap aluminum foil around the outside of the pan to prevent any batter from leaking out.
In the bowl of your stand mixer, beat on medium butter until smooth. Add sugar and mix until smooth about 2 to 3 minutes on medium speed.
Add eggs, one at a time, beating well after each addition.
Add flour and heavy cream alternately to sugar mixture, beginning and ending with flour.
Add vanilla and mix on low to medium until well combined.
Pour batter into a prepared 10-inch tube or bundt pan.
Bake for 1 hour 15-25 minutes at 325 degrees F. Test for doneness with a wooden pick The cake will be done with no crumbs or dry crumbs remain on the pick.
Cool in the pan for 20 to 25 minutes before inverting onto a serving tray to cool completely.
Store in an airtight container on the countertop 3 to 4 days.
