The sweet potatoes are the star—medium-sized and organic if you can find them, since they hold up best in the crock pot. Costco or Trader Joe's usually have the best selection, but any grocery store will work. Look for ones that feel heavy for their size—they're sweeter. Peeled and sliced into even rounds, they'll soften perfectly while absorbing all that spiced rum goodness. Pro tip: if you're using pre-cut sweet potatoes, pat them dry first—they'll caramelize better.
No spiced rum? Apple cider or orange juice works in a pinch, but trust me on the rum—it adds that special depth. For the celery crown, crisp stalks are key. If yours are limp, soak them in ice water for 10 minutes to perk them up. The brown sugar and granulated sugar can be swapped for coconut sugar if you're avoiding refined sugar, but regular white sugar works too. And if you're skipping the ice cream, a dollop of whipped cream or coconut whipped cream adds that same luxurious touch.
This dessert reheats beautifully—just pop the crock pot on low for 15 minutes. Store leftovers covered in the fridge for up to 5 days, though I rarely have any. For the celery crown, make it fresh when you're ready to serve so it stays crisp. The rum-infused sweet potatoes actually taste better the next day as the flavors meld. Portion into individual containers for easy grab-and-go treats all week—perfect for lunches or after-dinner snacks.

Step-by-step instructions for spiced rum sweet potatoes
Here's how to transform humble sweet potatoes into a decadent, rum-infused masterpiece with crispy celery crowns.
Prepare the Sweet Potatoes and Crock Pot
Peel the 3 lb sweet potatoes and slice each into ½-inch thick rounds. I like to cut them slightly thicker than usual because they'll soften beautifully in the slow cooker. Arrange the slices in a single layer at the bottom of your crock pot, slightly overlapping if needed.
In a small bowl, whisk together the 0.5 cup spiced rum, 0.25 cup brown sugar, 1 tsp vanilla extract, and 0.5 tsp salt. Pour this aromatic mixture evenly over the sweet potato slices, making sure each piece gets coated. The rum will infuse the potatoes with deep, warming flavors while keeping them moist throughout the cooking process.
Layer and Add Creamy Elements
Add the 2 whole cinnamon sticks to the crock pot, nestling them among the sweet potato slices. This will infuse the entire dish with subtle cinnamon aroma. Pour the 0.25 cup heavy cream over the top, letting it seep down between the layers.
Cover the crock pot and cook on LOW for 6 hours. This long, slow cooking time ensures the sweet potatoes become fork-tender while absorbing all those delicious flavors. I know 6 hours seems like forever, but trust me—this is where the magic happens. The rum will reduce slightly, creating a caramelized glaze on the potatoes.
Prepare the Celery Crown Topping
While the sweet potatoes cook, prepare the celery crown. Thinly slice the 3 whole celery stalks into ¼-inch thick rounds. In a small bowl, toss the celery with the 0.125 cup granulated sugar until evenly coated. This sugar will caramelize beautifully when baked, creating that perfect crunchy crown.
Spread the sugared celery evenly over the top of the cooked sweet potatoes. The sweetness of the sugar will complement the rum and cinnamon flavors perfectly. Return the crock pot to LOW heat for an additional 1 hour to allow the celery to caramelize and become crispy.
Finish and Serve with Style
Remove the cinnamon sticks before serving. Melt the 2 tbsp butter in a small saucepan over low heat, then drizzle it over the sweet potatoes and celery crown. This adds a luxurious richness that ties everything together.
For an extra indulgent touch, serve each portion with a scoop of 1 cup vanilla ice cream. The warm, spiced sweet potatoes paired with cool, creamy ice cream create a perfect balance of temperatures and flavors. The celery crown adds that satisfying crunch that contrasts beautifully with the soft potatoes.
Pro Tips For Making Baked Sweet Potato Crock Pot
- PIERCE THEM FIRST: Sweet potatoes take forever to soften in a crock pot—start by cutting them into 1-inch chunks (not slices) and piercing each piece 3-4 times with a fork. I learned this the hard way after a 7-hour cook still left me with rubbery centers.
- USE FULL-SIZE STICKS: Skip the pre-ground cinnamon for the sticks—it infuses flavor deeper and looks impressive. Add 2 whole cinnamon sticks to the crock pot before the rum, then remove them after 2 hours (they’ll get mushy). The sticks also help distribute heat more evenly.
- DON’T SKIP THE BROWN SUGAR MELT: The brown sugar needs to caramelize slightly for real depth. After dumping everything in, stir once at the 3-hour mark—this breaks up the sugar and lets it cling to the potatoes. If you’re in a hurry, sprinkle 1 tablespoon of water over the sugar first to kickstart the process.
- COVER WITH FOIL MIDWAY: The crock pot will steam like a sauna, and that’s fine—until it’s not. After 4 hours, tent the lid with foil to prevent the rum from evaporating too fast. This keeps the potatoes moist and the sauce syrupy, not dried out. (Yes, even if your crock pot manual says not to.)
Pro cooking tips for baked sweet potato crock pot
Sweet Potato Prep Pro Tips
Always peel your sweet potatoes before slicing—I find organic ones from Trader Joe’s work best because they’re consistently smooth. Cut them into ½-inch thick slices and pat them dry with a paper towel to prevent excess moisture, which can make them soggy in the crock pot. 🍠
For even cooking, arrange the slices in a single layer at the bottom of your crock pot, slightly overlapping if needed. If using a 6-quart crock pot, you’ll have room for all 3 lbs of potatoes without crowding.
Pro tip: If your sweet potatoes are uneven in size, cut the larger ones into smaller rounds—they’ll cook faster.
Rum Infusion Secrets
Use dark spiced rum like Captain Morgan or Kahlúa for the deepest flavor. Pour the rum mixture evenly over the potatoes, making sure each slice gets coated.
If you’re concerned about alcohol content, let the crock pot sit uncovered for 10 minutes before covering—this allows most of the alcohol to evaporate while keeping the flavor.
For extra warmth, add 1 tbsp ground cinnamon directly to the crock pot along with the cinnamon sticks. This ensures the spice infuses throughout the potatoes rather than just settling at the bottom. Stir gently once after pouring the rum mixture to distribute the flavors evenly.
Celery Crown Perfection
Select crisp celery stalks with no brown spots—they’ll caramelize beautifully. Thinly slice them into ¼-inch rounds and toss with ¼ cup granulated sugar until fully coated. Spread them evenly over the potatoes right before the final 1-hour cooking time to maintain their crunch.
For a glossy finish, brush the celery crown with a tiny bit of melted butter after the 1-hour cooking time. This adds a subtle richness that complements the sweetness perfectly.
If you’re short on time, you can also broil the celery crown in the oven for 3-5 minutes at 400°F for instant caramelization.
Crock Pot Temperature Mastery
Cook the sweet potatoes on LOW for 6 hours—this slow method ensures they become fork-tender without drying out. If you’re short on time, switch to HIGH for 3-4 hours, but monitor closely to prevent overcooking. The rum will reduce slightly, creating a caramelized glaze on the potatoes.
After the initial cooking time, return the crock pot to LOW for the final 1 hour with the celery crown. This gentle heat ensures the celery caramelizes without burning. If your crock pot has a keep-warm function, use it to maintain the perfect temperature while you finish other tasks.

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
No, sweet potatoes are essential for this recipe! Their natural sweetness and creamy texture pair perfectly with the spiced rum and caramelized sugar. Regular potatoes would absorb too much moisture and lack the rich, sweet flavor that makes this dessert special.
How do I adjust the recipe for a smaller crock pot?
For a 3-4 quart crock pot, reduce the sweet potatoes to 1.5 lbs and halve all other ingredients except the celery crown. Cook on LOW for 4-5 hours instead of 6. The smaller volume will cook faster, so keep an eye on it after 3 hours to check for doneness.
What if I don't have spiced rum?
No problem! Substitute with ½ cup apple cider or orange juice for a similar sweetness. For extra warmth, add ½ tsp cinnamon and ¼ tsp nutmeg directly to the crock pot. The flavor will be different but still delicious—just slightly less boozy and complex.
Can I make this ahead of time?
This dessert actually tastes better the next day as the flavors meld. Store covered in the fridge for up to 5 days. Reheat on LOW for 15-20 minutes before serving. The celery crown should be made fresh when serving to maintain its crispness, but you can prepare the sugared celery ahead and caramelize it just before serving.
Why does my celery crown turn out mushy?
Mushy celery usually means it cooked too long or wasn't crisp enough to start. Use very fresh celery and slice it ¼-inch thick—thinner slices caramelize faster. Spread it evenly over the potatoes right before the final 1 hour on LOW heat. For extra crunch, broil for 3-5 minutes at 400°F right before serving.
