Preheat the oven to 350ºF (180ºC). Generously grease and flour a 6-inch (3-cup) bundt tin.
Add the sugar, flour, and baking powder to a deep bowl. Whisk to blend.
Add the eggs, cream, and vanilla. Whisk until well blended.
Scrape the batter into the prepared tin. Gently tap the pan on the counter to smooth out the batter. Bake until deep golden and a toothpick inserted in the center comes out clean, about 45 minutes.
