1Preheat oven to 350 degrees.
Spray bundt cake pan generously with PAM. Sprinkle the sugar/cinnamon combination inside the bundt pan and move around the entire pan; be generous with this, too. If a lot remains, toss it out. This will form a sweet crust for your cake, thus no frosting needed.
Mix cake mix, pudding, orange juice, oil, eggs (1 at a time), vanilla and poppy seeds.
Pour into bundt cake pan and bake at 350 degrees for 45 minutes.
