An easy dessert that works when you don't have as much time to make the dessert. It works with a variety of meals, so is quite versatile. This recipe is from the Cake Mix Doctor Cookbook.
Preheat oven to 350°. Lightly grease and flour the Bundt pan.
Finely chop the pecans and sprinkle them in the bottom of the prepared pan.
Place cake mix, pudding mix, water, rum, and eggs in a large mixing bowl and blend with an electric mixer on low speed for 1 minute. Scrape down the sides of the bowl and then mix on medium speed for 2-3 minutes.
Pour batter into Bundt pan and place in oven. Bake for 50-55 minutes or until the cake springs back when lightly pressed with your finger. Let cool for 5 minutes, then remove from pan onto wire rack. While it is cooling on a wire rack, you can make the glaze.
Glaze
Add all glaze ingredients to a small sauce pan and place over low heat until butter melts and sugar is dissolved. Raise heat to medium stirring constantly as it begins to boil. Let cook for 2-3 minutes, remove from heat.
Place warm cake onto the serving dish. Poke holes in the top and sides of the rum cake with a skewer or chopstick. Be sure to poke holes in the center as well. Using a spoon, drizzle the glaze slowly over the cake taking care to let it soak into the holes.
