Here are a few suggestions that have worked for me: Use a light colored pan. Spray the pan right before pouring in the batter. I swear by Wilton's Bake Ease Spray! Cool the cake for only about 15 minutes. Any longer will increase the chances of sticking. Swirl a butter knife or metal spatula around the edges of cake to help release it. Turn pan over, give it a gentle tap around the edges and on the top of pan to help loosen the cake. The Kitchn has a complete article about different methods tested. They recommend a homemade "Cake Goop" which is a combination of vegetable oil, shortening and flour. I have not tested this so I can't speak to the method's success. King Arthur Baking has some helpful tips as well.
