No, a bundt pan is not necessary for this death by chocolate cake. You have a couple of options: A tube pan works and would require the same amount of baking. A 13 by 9 pan is great. Bake for 30 to 40 minutes. Mini bundt pans work and need around 20 minutes for cooking time. You can also use 2 nine inch pans and bake for 30 to 40 minutes. You can even make cupcakes! (I would recommend the chocolate buttercream frosting used on these chocolate cherry cupcakes.) For bake time, follow the instructions on the box for cupcakes. I recommend watching your cake closely, beginning about 2 minutes before the earliest cook time. The cake is done when a toothpick inserted into the center comes out with a few moist crumbs or clean.
