Rhubarb Crumble with Raspberries & Almonds

Rhubarb and raspberries make a lively, tart filling beneath buttery oat and almond crumbs. As the fruit softens, its juices bubble between the golden pieces on top. This crumble keeps that contrast on the spoon: tender fruit, nutty crunch, and a little sweetness from the topping.

Rhubarb and berries beneath oat and almond crumbs

Rhubarb brings the sharp note, with raspberries adding berry flavor and more juice. Sugar balances the fruit, while vanilla pudding powder contributes vanilla flavor and helps bind the juices as the filling cooks. Use a cooking-type powder and distribute it evenly so no dry pockets remain.

The topping combines wheat flour, brown sugar, rolled oats, almonds, butter, and salt. The oats give it a coarse texture and the almonds add a nutty bite.

Prepare the stalks and leave the topping crumbly

Use rhubarb stalks only. Remove and discard the leaves; they are toxic and must not be eaten. Wash the stalks, trim the ends, and cut similar-sized pieces. Rinse fresh raspberries gently and drain them well, then handle them lightly when combining the filling so they are not crushed before baking.

Rub cold butter into the dry topping ingredients until coarse crumbs form. Keep the mixture loose, with some smaller crumbs between larger pieces. Scatter it evenly over the fruit without packing it down. The filling needs to cook beneath the topping, so avoid a thick mound of crumbs in the center.

Bake in a preheated oven at 375°F (190°C), with 30–40 minutes as a guide. The topping should be golden and baked through, the juices bubbling, and the rhubarb tender when checked through a gap. Do not taste the raw topping because it contains uncooked flour. Let the finished crumble settle briefly before serving; the bubbling fruit underneath is very hot.

Serve the tart fruit with gentle vanilla

Spoon the crumble into bowls, bringing up fruit and crumbs together. Vanilla Pudding makes a soft, sweet accompaniment in a separate small bowl. Its milk, sugar, and vanilla pudding powder produce a spoonable pudding, which sits beside the tart fruit without pouring over all the crumbs.

For a cold accompaniment, add Vanilla Ice Cream just before eating. The vanilla bean and cooked custard base complement the berries and almonds while the scoop begins to melt against the warm filling.

Refrigerate leftovers promptly in shallow containers at 40°F (4°C) or below, within 2 hours or 1 hour above 90°F (32°C). If reheating, bring the center to 165°F (74°C). Keep pudding or ice cream separate.

Small details for the fruit and topping

Break up the almonds for easier spoonfuls. If yours are whole, chop them into manageable pieces before mixing the topping. This spreads their crunch through the crumbs.

Protect the oven from drips. If the filling comes close to the dish rim, set the dish on a rimmed baking sheet to catch any juice that bubbles over.

Optional aromatic additions

Citrus zest. A little finely grated orange or lemon zest adds a fragrant note to the fruit. Wash the citrus first and use the colored peel without the bitter white layer.

A hint of ginger. A little ground ginger in the topping brings gentle warmth alongside the sharp rhubarb. Keep it subtle so the raspberry flavor still comes through.

Prepare ahead without soaking the crumbs

Keep prepared fruit and crumble topping covered separately in the refrigerator, then assemble just before baking. This gives the topping less time to absorb fruit juice.

Reheat a portion in an ovenproof dish when you want a drier surface; the microwave tends to soften the crumbs. Add the creamy accompaniment only to the portion being served.

Frequently asked questions

Should the filling be completely dry?
No. Rhubarb and raspberries release juice as they cook. You want tender fruit with some bound juice beneath the crumbs. Let the baked crumble settle briefly before deciding whether it is too loose.

Do I need to add extra cornstarch?
Not automatically. This version already contains vanilla pudding powder for flavor and binding. Adding another thickener can make the filling pasty rather than pleasantly juicy.

What if the almonds brown before the rhubarb is tender?
Loosely shield the top with foil and continue baking until the filling is tender and the topping is fully cooked. Check through a gap instead of judging only by the almond color.
