Start by preheating your oven to 325°F (165°C). As it heats, prepare a bundt pan by greasing it generously. A non-stick spray or butter will help your cake slide out easily when it’s done.

In a mixing bowl, crack the four eggs and add the cold water and canola oil. Give it a good whisk until the mixture is smooth and combined. This step is essential for a fluffy texture.

Next, gradually add the yellow cake mix and vanilla pudding mix into the egg mixture. Use an electric mixer on medium speed until the batter is smooth. Take your time; a well-mixed batter ensures an even cake.

Fold in those toasted nuts and the dark rum. The rum not only enhances the flavor but also adds a festive kick that’s hard to resist. If you choose to use orange zest, this is the time to stir it in as well.

Pour the batter into your prepared bundt pan. Bake in the preheated oven for about 45 to 50 minutes. You’ll know it’s ready when a toothpick inserted into the center comes out clean.

While the cake is baking, let’s whip up that glorious rum glaze! In a small saucepan, melt the unsalted butter over medium heat. Stir in the granulated sugar, dark rum, and water. Bring to a gentle boil and let it simmer for about 5 minutes. Set it aside once your cake is out.

Once the cake has cooled for about 10 minutes, invert it onto a serving platter. Poke holes all over the top with a skewer. This will allow the glaze to seep in beautifully. Pour the warm glaze over the cake, letting it soak in while you admire your handy work.
