Add raw, unpeeled rhubarb stalks to the slow cooker with just two other ingredients and create a homemade treat so delicious everyone will be asking for more.

This 3-Ingredient Slow Cooker Rhubarb Dessert is all about turning a bold, tart ingredient into something soft, sweet, and comforting. As the rhubarb cooks slowly with sugar and vanilla, it breaks down into a smooth, jam-like texture, creating its own rich syrup. The result is a vibrant, flavorful dessert with the perfect balance of tangy and sweet.

3-Ingredient Slow Cooker Rhubarb Dessert

Ingredients

• 4 cups rhubarb stalks, unpeeled and cut into 1-inch pieces (about 1 lb)
• ½ to ⅔ cup granulated sugar
• 1 teaspoon vanilla extract

Instructions

1. Prepare the rhubarb
Trim off the ends and chop the stalks into even 1-inch pieces. Leave the skin on for better color and texture.

2. Combine ingredients
Place the rhubarb in the slow cooker, then sprinkle the sugar and vanilla over the top. Stir gently to combine.

3. Cook
Cover and cook on LOW for 3–4 hours or HIGH for 1½–2 hours, until the rhubarb is very soft and has released its juices.

4. Stir and adjust
Give the mixture a good stir to break it down further. Taste and add a little more sugar if needed.

5. Let it thicken
Remove the lid and let the dessert sit for 5–10 minutes before serving so the syrup thickens slightly.
