Rhubarb Fool
This rhubarb fool is a simple, no-bake dessert made with lightly sweetened whipped cream and swirls of rhubarb compote. It’s quick to put together and works especially well in spring when rhubarb is in season.
A fool is a traditional British dessert made by folding fruit into whipped cream. It usually includes some sugar, but the amount varies depending on how tart the fruit is.
The key is to only partially fold the mixture so you get beautiful swirls rather than a fully blended cream. That contrast between the airy base and the tart, tangy fruit is exactly what makes this dessert work without being overly sweet.
If you’re looking for other ways to use rhubarb, this Strawberry Rhubarb Crisp or these Rhubarb Bars are great baked options.
- No baking required – aside from making the compote on the stovetop (the same rhubarb compote I posted last week), everything is mixed in a bowl.
- Quick to assemble – once the compote is ready, the rest takes just a few minutes.
- Light but satisfying – creamy without feeling heavy.
- Make-ahead friendly – it needs a short chill to set, but can be made several hours in advance.
Ingredients
These are just some notes on selected ingredients. Scroll down for the full recipe.
- Heavy cream – must be cold so it whips properly.
- Powdered sugar – sweetens the cream and dissolves easily.
- Vanilla extract – it’s not traditional, but it adds a bit of depth to the cream.
- Rhubarb compote – you can use any other type of compote you’d like, like this Raspberry Compote. Store-bought also works!
How to Make It
Start by making sure both your cream and rhubarb compote are very cold. If you have time, chill your mixing bowl and beaters as well. This helps the cream whip up more easily and hold its shape.
In a chilled bowl, beat the heavy cream until it just begins to thicken. Add 1 tablespoon of powdered sugar and the vanilla extract, then continue beating until stiff peaks form. The cream should stand straight up when you lift the beaters.
Taste the whipped cream and add the remaining powdered sugar if you’d like it a bit sweeter.
Add 1 cup of the chilled rhubarb compote to the whipped cream. Using a large spatula, fold it in very briefly, just 2–3 gentle folds. You want visible streaks rather than a fully mixed pink cream.
Spoon the mixture into glasses or jars, then top each serving with a bit more compote. Chill for about 30 minutes before serving so the flavors meld and the texture firms up slightly.
- Keep everything cold – warm cream won’t whip properly.
- Don’t overmix the compote – a few gentle folds is enough to keep the swirled look.
- Watch the peaks – stop whipping once stiff peaks form to avoid grainy cream.
- Use clear glasses – shows off the layers and swirls.
Troubleshooting
- Cream won’t whip – it wasn’t cold enough.
- Mixture looks flat pink – it was overmixed; fold less next time.
- Too runny – the compote or cream was too warm.
- Too tart – add a little more powdered sugar to the cream.
How to Make Ahead, Store and Freeze
You can make the rhubarb compote ahead of time and keep it refrigerated until needed. The assembled fools are best made shortly before serving, but they can be chilled for a few hours.
Store any leftovers in the refrigerator for up to 2 days. The texture will soften slightly as it sits.
The fool doesn’t freeze well, but the compote itself freezes well if you want to prep it in advance.
Rhubarb Fool
Ingredients
Compote:
- 1 pound (454 grams) rhubarb cut into 1/2” pieces (about 4 cups) – see notes if using frozen
- 1/2 cup (100 grams) granulated sugar or 6 tbsp (120 grams) Grade A maple syrup + more to taste
- 1 tablespoon freshly squeezed lemon juice
- 1 teaspoon lemon zest
- pinch salt
Fool:
- 1 cup (237 ml) heavy cream cold
- 1-2 tablespoons powdered sugar
- 1/2 teaspoon vanilla extract
- 1 cup (255 grams) above rhubarb compote
Instructions
Compote:
- Combine all compote ingredients in a medium saucepan.1 pound (454 grams) rhubarb, 1/2 cup (100 grams) granulated sugar, 1 tablespoon freshly squeezed lemon juice, 1 teaspoon lemon zest, pinch salt
- Cook over medium heat, stirring occasionally. If you need to, you can add 1-2 tablespoons of water to prevent it from burning (some rhubarb takes longer to release its juices).
- Once it starts bubbling, reduce to medium-low.
- Simmer for about 8–15 minutes, until the rhubarb softens and breaks down. It shouldn’t be syrupy, but not quite as thick as jam. If your rhubarb still isn’t tender and it’s getting too thick, add a little more water. It will thicken more as it cools.
- You can use it warm or let it cool until room temperature, about an hour, and then refrigerate for another 1-2 hours until cold if using in a dessert. Refrigerate in an airtight container for up to 5 days or freeze for up to 3 months.
Fool:
- Make sure the cream and compote are very cold. It’s also helpful to put the bowl and beaters in the fridge if you have time. In a chilled bowl, beat the heavy cream until it begins to thicken.1 cup (237 ml) heavy cream
- Add 1 tablespoon powdered sugar and the vanilla, and continue beating until you reach stiff peaks (the cream should stand straight up when you lift the beaters). Taste and add the remaining powdered sugar, if desired.1-2 tablespoons powdered sugar, 1/2 teaspoon vanilla extract
- Add 1 cup of the chilled compote. Using a large spatula, fold the compote very briefly, only 2 or 3 turns. You want to see distinct white and pink streaks. Immediately spoon the mixture into your glasses.1 cup (255 grams) above rhubarb compote
- Top each glass with a tablespoon (or more) of the remaining compote. Chill for 30 minutes to let the flavors marry and the structure firm up.
- The assembled fools are best made shortly before serving, but they can be chilled for a few hours. Store any leftovers in the refrigerator for up to 2 days. The texture will soften slightly as it sits.
Notes
- If using frozen rhubarb, do not thaw before using. Add it straight to the saucepan while frozen, otherwise it will release too much liquid and throw off the consistency. Expect it to be closer to the longer end of the cooking time. Frozen rhubarb releases more juice as it cooks, so you’re less likely to need to add water (and may not need any at all), but you may want to turn down the heat at the beginning and cover it. Also keep in mind that the color will be more beige with a little pink rather than a pretty pink!
- The compote yields 468 grams or 1.83 cups. You’ll only need 1 cup of that for the fools.
