The cake can be stored at room temperature for up to 3 days.
Bundt cakes can be tricky to unmold. Be sure to thoroughly butter and flour the pan in Step 1. After the baked cake has cooled, gently run a knife blade or offset spatula around the edge of the pan if the cake needs loosening. To unmold, set a cooling rack on top of the cake pan and gently flip the two over. Slowly lift the cake pan off the cake about 1/4 inch, jiggling it a bit if necessary. If you have a particularly stubborn cake, rap the bottom of the pan with a measuring cup or an offset spatula.
