Preheat oven to 350 degrees Fahrenheit. Grease a Bundt pan with some butter. Sprinkle flour all over the greased surface and shake out the excess.

In a small bowl combine flour, cornstarch, baking powder, and salt. Whisk together. Set aside.

In another bowl combine eggs and vanilla. Mix well with the help of a fork, until combined.

In the bowl of an electric mixer fitted with the whisk attachment, whip up the heavy cream almost until stiff peaks are formed.

Gradually incorporate the egg mixture. Add the sugar, gradually, and mix some more. On slow speed, add flour mixture in small amounts, mixing in between.

Pour into the prepared Bundt pan. Bake for 30-40 minutes, until toothpick comes out dry but with some crumbs on it. Cake will look pale, but that’s fine. Don’t overbake it.
