Ingredients:
For the Dessert:*
4 cups rhubarb, trimmed and cut into 1-inch pieces
½ to ⅔ cup granulated sugar (adjust to taste)
1 teaspoon pure vanilla extract
Instructions:
Step 1: Prepare the Rhubarb*
Rinse the rhubarb under cold water and pat it dry with a clean kitchen towel. Trim the ends and discard the leaves (they are toxic). Cut the stalks into 1-inch pieces.
Step 2: Layer in the Slow Cooker*
Place the rhubarb pieces evenly into the slow cooker. Sprinkle the sugar over the top and drizzle with the vanilla extract.
Step 3: Stir and Cook*
Gently stir to distribute the sugar and vanilla evenly. Cover the slow cooker with the lid. Cook on LOW for 3-4 hours or on HIGH for 1.5-2 hours, until the rhubarb is soft and broken down.
Step 4: Taste and Adjust*
Stir the dessert well and taste. If it’s too tart for your liking, stir in a little more sugar until it reaches your desired sweetness.
Step 5: Thicken and Serve*
Let the dessert sit uncovered for 5-10 minutes to thicken slightly before serving. Serve warm or chilled.
Tips:
- Adjust Sugar to Taste: Rhubarb can vary in tartness. Start with ½ cup of sugar and add more after tasting, if needed.
- Use Fresh Rhubarb: Fresh, firm stalks work best. Avoid limp or overly woody rhubarb.
- Don’t Overcook: The rhubarb should break down and become soft, but not completely mushy. Check at the lower end of the cooking time.
- Add a Pinch of Cinnamon: For extra warmth, add ½ teaspoon of ground cinnamon along with the vanilla.
- Try Other Fruit: This method also works beautifully with sliced apples, peaches, or berries — adjust sugar and cooking time as needed.
Serving Suggestions:
- Spoon warm over vanilla ice cream or whipped cream.
- Serve over pancakes, waffles, or French toast.
- Layer with yogurt and granola for a fruit parfait.
- Use as a topping for pound cake, cheesecake, or angel food cake.
- Spread on toast or biscuits as a quick jam-like treat.
Storage Options:
- Refrigerator: Store in an airtight container in the refrigerator for up to 1 week.
- Freezer: This dessert freezes beautifully for up to 3 months. Cool completely, then transfer to freezer-safe containers. Thaw in the refrigerator or at room temperature.
- Make-Ahead: Prepare the rhubarb dessert a day or two in advance and chill. The flavors will deepen and meld.
