This method is the best way to grease a bundt pan to ensure your cake does not stick to the pan! It has worked for me every single time, no broken bundt cakes here! 1. Melt one tablespoon of butter in a small bowl. 2. Use a pastry brush to spread the butter in all the groves of the pan.  3. Add a tablespoon of flour to the pan and shake it to help it evenly coat the pan.  * After you take the cake out of the oven, let it cool for no more than 5 minutes. Use a knife to loosen it from the sides, then turn it out onto a cooling rack. If you allow it to cool in the pan, it will likely stick.
