A richly buttery, rum-soaked Bundt cake with double rum in batter and sauce — supremely moist, easy to make ahead, and perfect for holiday entertaining.

I introduced this version at a large family gathering the first winter I made it and watched it vanish quickly. People kept returning for small second slices because the rum flavor lingers without overpowering, and younger adults loved it while older relatives appreciated the buttery, nostalgic cake flavor. Over time I adjusted the rum quantity and the number of fork pokes so each slice gets an even, juicy hit of sauce. It’s become the dessert I reach for when entertaining because it stores well and improves with time.
When shopping, choose a dark rum with rich flavor rather than an overproof mixing rum; this cake benefits from rum with molasses and caramel notes. If you prefer milder alcohol presence, use 3/4 cup total rum instead of a full cup, or swap half for strong brewed coffee for a complementary depth.
My favorite part is how the cake transforms over three days: it becomes silkier and the rum aroma deepens. At day three it seems to hit a flavor peak where the sauce and crumb are perfectly married. I’ve shipped this cake to friends for celebrations and it arrives tasting even better than when sliced fresh, which makes it my go-to make-ahead dessert for holiday travel.
Store the cake at room temperature in an airtight container or wrapped tightly in plastic wrap to prevent the sauce from evaporating. Do not refrigerate; cold temperatures will firm the butter and reduce the sauce’s glossy mouthfeel. For longer storage, the cake freezes well: wrap individual slices in plastic and then foil, and freeze up to 3 months. Thaw slices overnight at room temperature and allow them to rest for an hour to regain moisture and sheen before serving.
If you prefer less alcohol flavor, reduce the total rum to 3/4 cup and replace the remaining 1/4 cup in the sauce with strong brewed coffee or orange juice for citrus notes. For a dairy-free version, replace butter in the sauce with a plant-based stick margarine that tolerates heat. To make this gluten-free, use a gluten-free yellow cake mix and ensure the pudding mix is gluten-free. Note that texture will vary slightly with these swaps; gluten-free mixes can be a bit denser.
Slice the cake with a serrated knife and serve at room temperature. Offer lightly whipped cream or a scoop of vanilla ice cream to temper the boozy kick for guests who prefer it. For an elegant presentation, garnish with toasted flaked coconut or a dusting of powdered sugar. Pair with strong coffee, black tea, or a dessert wine that complements the rum’s molasses tones for a complete dessert course.
Rum cakes are a tradition in Caribbean and Southern U.S. cooking, where dark rums and butter-heavy sweets converge. The technique of pouring a warm alcohol syrup over a finished cake creates moistness and preserves the alcohol’s aromatic qualities. This Americanized Bundt adaptation blends Caribbean flavor with the convenience of boxed cake mixes, making a dessert that nods to rum-soaked regional classics while remaining accessible to home cooks everywhere.
In winter, boost warmth with 1/2 teaspoon ground cinnamon and a pinch of nutmeg in the batter; for a spring twist, stir in 1/2 cup finely chopped dried pineapple and reduce rum slightly. Holiday versions can incorporate toasted pecans into the sauce for crunch, or brush the cooled cake with a citrus-rum glaze for brightness during warmer months. Adjust extracts — coconut for summer, vanilla for year-round — to suit seasonal menus.
Make the cake two days ahead: complete the cake and sauce, pour half the sauce after the first hour, then invert and pour the remaining sauce. Wrap airtight and store at room temperature. For individual portions, slice and wrap, or bake in mini Bundt pans (adjust bake time) to create portable desserts for parties. Reheat slices briefly in a low oven for a warmed, just-baked experience.
End with confidence: this cake is forgiving, travels well, and rewards patience. Whether you’re hosting a holiday crowd or gifting a neighbor, the double rum treatment results in a memorable dessert that feels celebratory and comforting at once.
Grease and flour the Bundt pan generously and tap out excess flour to avoid sticking in crevices.
Poke many holes with a fork so the sauce distributes evenly; about 60–80 pokes is ideal for a 12-cup pan.
If the sauce crystallizes after standing, reheat gently and whisk until smooth before pouring.

Yes. Store airtight at room temperature for up to 10 days; the flavor improves over 48–72 hours. Do not refrigerate.

This Supremely Moist Double Rum Bundt Cake recipe makes perfectly juicy, tender, and flavorful steak every time! Serve with potatoes and a side salad for an unforgettable dinner in under 30 minutes.

Preheat oven to 325°F and thoroughly grease and flour a 12-cup Bundt pan to ensure the cake unmolds cleanly.
Beat cake mix, pudding mix, eggs, water, oil, 1/2 cup rum, and extract with a handheld electric mixer on high for about 2 minutes until smooth. Batter will be thin.
Pour batter into prepared pan and bake about 45 minutes, or until a toothpick comes out clean or with a few moist crumbs. Cool in pan on a wire rack.
Melt butter in a medium high-sided saucepan, add sugar and water and boil rapidly 4–5 minutes while whisking until frothy. Remove from heat and carefully whisk in 1/2 cup rum, return to heat 1 minute, stir in salt and transfer to a measuring cup.
Poke about 75 holes in the cake while still in the pan. Slowly pour 1 cup sauce over the cake and allow to absorb for about 1 hour. Invert cake, poke again, and pour remaining sauce into holes. Let rest 1–2 hours before slicing.
