Ingredients
For the Crockpot Sweet Potatoes:
- 4 large sweet potatoes, peeled and cut into 1-inch cubes
- ½ cup unsalted butter, melted
- ½ cup brown sugar, packed
- ¼ cup pure maple syrup or honey
- 1 teaspoon cinnamon
- ¼ teaspoon nutmeg
- 1 teaspoon pure vanilla extract
- ¼ teaspoon salt
- 1 cup mini marshmallows (for mixing in, optional)
For the Marshmallow Topping:
- 2 cups mini marshmallows
- Optional: ½ cup chopped pecans or walnuts for crunch
Instructions
- Prepare the Sweet Potatoes:
Peel and cube the sweet potatoes into even 1-inch pieces to ensure they cook evenly. Place them directly into the crockpot. - Make the Brown Sugar Butter Mixture:
In a small bowl, whisk together the melted butter, brown sugar, maple syrup (or honey), cinnamon, nutmeg, vanilla, and salt. Pour this luscious mixture over the sweet potatoes. - Mix and Cook:
Gently toss to coat all the sweet potato pieces with the buttery-spiced mixture. Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the sweet potatoes are tender and easily pierced with a fork. - Optional Mix-In:
For extra gooey sweetness, fold in 1 cup of mini marshmallows during the last 15 minutes of cooking. They’ll melt into the potatoes, creating a creamy layer of flavor. - Add the Marshmallow Topping:
Once the sweet potatoes are tender and fragrant, sprinkle the remaining mini marshmallows evenly over the top. Cover the crockpot again and let the marshmallows soften for about 10–15 minutes — just until they start to melt and turn glossy. - Toast the Marshmallows (Optional but Recommended):
For that irresistible golden finish, remove the crockpot insert and place it under your oven’s broiler for 1–2 minutes, watching closely to prevent burning. The marshmallows will puff up and caramelize beautifully. - Serve and Enjoy:
Spoon generous portions into serving bowls, making sure each scoop includes both creamy sweet potato and toasted marshmallow topping. Garnish with chopped pecans or a dusting of cinnamon if desired.

The sweet potatoes slowly absorb the buttery-spiced syrup as they cook, creating a dish that’s creamy, caramelized, and rich from edge to edge. And the best part? You can free up your oven for other dishes while this one quietly works its magic.
