The best part about this cake, aside from it being just totally delicious, is the glaze that gets soaked into it. It’s what takes this cake from being just “ok” to INCREDIBLE.

It’s the perfect cake for parties, get togethers, birthdays or just because.

Expert Tips

  • The glaze is key to making this key moist! Be sure to use any of the extra glaze that collects at the bottom of the cake on the plate and pour it back into the cake. We want all of that goodness in the cake!
  • You can also pour the glaze onto the cake while it’s still in the bundt pan to make this part easy.
  • This cake is really good as it sits so it’s a great make-ahead cake. If you can, allow 1-2 hours for the glaze to really absorb into the cake before serving.
  • When making the ganache, don’t let the heavy cream get too hot. Just warm enough to melt the chocolate.

How to prevent bundt cakes from sticking to the pan

  • Use a non-stick coated pan! It’s all about the pan. If your pan is old and questionable, don’t waste your time.
  • Grease your pan. There is a debate on using butter or shortening. I always use butter and then sprinkle with flour and have had good luck. If you haven’t and want to try something else, try solid shortening and sprinkle with flour or granulated sugar!

How to store a bundt cake

  • This American-Classic dessert is best stored at room temperature wrapped in plastic wrap for up to 4 days, or in the fridge for 1 week.
  • It also freezes very well. Wrap in plastic wrap and store in a freeze safe container for up to 3 months.

For the cake

  • Preheat the oven to 325°F. Grease a 10-inch bundt pan with a little softened butter and sprinkle an even layer of flour in the pan, shaking out any excess flour. Alternatively, you can spray with a non-stick baking spray. Set aside.
  • Beat the eggs, oil, water and rum with a hand mixer, or using a stand mixer, just until mixed.
    4 large eggs, 1/2 cup canola oil, 1/2 cup Bacardi rum, 1/2 cup filtered water (or milk)
  • Then add in the cake mix and instant pudding and beat just until smooth.
    1 box yellow cake mix (15.25 oz), 1 box instant vanilla pudding (3.4 oz)
  • Pour the batter into the prepared bundt pan and bake for 50-55 minutes or until a toothpick inserted in the middle comes out clean. The cake will have a light golden brown color on top when finished.

For the glaze

  • Melt the butter in a medium sized saucepan over medium-low heat. Then add the sugar and water and stir. Let this simmer for 1-2 minutes.
    8 Tbsp. unsalted butter, 1/4 cup filtered water, 1 cup granulated sugar
  • Remove from heat and stir in the rum. Pour into a 2 cup measuring cup.
    1/2 cup Bacardi rum
  • You can leave the cake in the bundt pan so all the glaze soaks into it (I like this option for easier clean up) or invert the cake onto a plate or cooling rack, just make sure something is underneath it to catch the glaze so you can re-glaze it with all the glaze that drips down the sides.
  • Prick the cake all over using a fork or toothpick and then slowly pour 1/2 cup of the glaze into the cake. The cake will start to absorb the glaze. Add another half cup of the glaze and wait a few more minutes to absorb it. Repeat until glaze is finished. Allow the glaze to fully soak into the cake. If you kept the cake in the bundt pan, you can invert onto a serving plate once glaze has been absorbed.

For the ganache

  • Pour the chopped chocolate pieces in a heat proof bowl. Heat the cream in a small saucepan over medium heat just until it’s warm, do not let it boil. Pour the warmed cream over the chocolate and let it sit for 2-3 minutes. The warm cream will melt the chocolate. Stir or whisk until it is smooth and creamy. Pour the ganache over the cake, as it cools the ganache will set up.
    4 oz. semi-sweet chocolate bar, chopped, 1/2 cup heavy cream
  • Slice and enjoy!



    • Storage: best stored at room temperature wrapped in plastic wrap for up to 4 days, or in the fridge for 1 week. It also freezes very well. Wrap in plastic wrap and store in a freezer safe container for up to 3 months.

This was the most DELICIOUS cake! It was my first time making it and the recipe was easy to follow! I made it for a girls night and my friends had never had it before! We all couldn’t believe how moist and flavorful it was. My mom came over and enjoyed some as well. I will most definitely be making again for the holidays! I know for a fact there will be NO leftovers 😊

Delicious cake! Was a hit for a party I had tonight for a football game. I forgot to take a picture before we cut into it so the picture is after we cut it. I used a dark rum and it was perfect.
