For baking a Duncan Hines cake mix in a bundt pan at high altitude (generally above 3,500 feet), it is recommended to increase the baking time. Typically, you may need to add around 5-10 minutes to the suggested baking time. Check for doneness by inserting a toothpick into the center; it should come out clean. Adjustments may vary, so keep an eye on your cake as it bakes.
