Bang the bundt pan on the counter to further settle the batter.
Place the bundt pan in a 350 degree oven for 1 hour or more until a toothpick inserted in several spots comes out clean.
Let the pan set on a cooling rack for 15 minutes.
Place the serving platter on top of the bundt pan and flip it over tapping gently if needed to pop out the cake.
