Pour the batter into the bundt pan and firmly tap the pan on the countertop a few times to release any air. Bake the cake until golden and a tester comes out clean. 55 to 60 minutes, rotating halfway through.
Set the cake, still in its pan, on a rack to cool for 30 minutes, then invert the cake pan onto a plate for 15 minutes. Remove the bundt pan and allow cake to cool sightly.
Using a powdered sugar duster, or a mesh strainer, sprinkle the powder sugar on the warm bundt cake.
