1. Start by buttering a large bundt pan. This is easily done with the paper wrapping from the butter.
2. Mix all the wet ingredients: melted butter, eggs, preserve and buttermilk in a large mixing bowl.
3. Add the jar or zip top bag with cake mix and stir on the slowest speed with a beater or by hand.
4. Pour the batter in the prepared baking pan and put on lower rack in the over. Bake at 350F for approx. 55 min. or until a cake tester comes out clean. If the cake appears pale use the broiler for a half minute or so at the end. Just pay close attention so that the cake does not burn.
Allow the cake to cool somewhat before putting it upside down on a rack or cutting board.
Enjoy with coffee or a cold glass of milk!
Allow to cool completely before serving. Any leftover cake is best stored wrapped in plastic or a ziplock bag inside the fridge.
