Timing is very important to release a bundt cake out of its pan without any issues. Let the bundt cake cool for 10-15 minutes. Slide a butter knife around the edges and centre hole to help release the cake, then flip the cake onto a serving tray while it's still warm (tap the pan all over if the cake doesn't release right away). Don't wait until the cake is cool as it will stick to the sides and if you flip it when it's too hot it may break apart in the pan.
