How do you keep a bundt cake from sticking to the pan? – First thing is to choose a non-stick Bundt pan. If you could get a silicone Bundt pans, they work really well! – Next thing is to make sure you grease the pan with baking spray. You could also try to grease it with butter, but we prefer baking spray and never have the cake stick. – If you grease with butter, the next step is to flour the pan slightly. Gently tap out any excess flour before adding the cake batter.
