Choose a Bundt cake pan with a non-stick coating.  It is still important to grease your pan well.  Be sure to grease every nook and cranny.  Butter is not the best choice for greasing a Bundt pan as the milk solids may cause sticking. (I use coconut oil)  Sprinkle flour into the pan and tap the sides to distribute it evenly.  When the cake is finished baking, it is important to let it cool for 10 to 20 minutes.  Then invert your cake over a wire cooling rack.  Let cool completely before adding icing.
