A dessert that’s both familiar and a little bit fancy is exactly how I’d describe my Blueberry Crumble Fool. It’s a playful twist on two classics: the cosy warmth of a crumble and the creamy charm of a traditional English fool. Except here, it’s dressed up for a party, served in tall glasses with layers that make you want to dive in spoon-first.
The first time I made Blueberry Crumble Fool, it was more of an experiment than anything else. I had leftover crumble topping from a baking session, a punnet of blueberries that were begging to be used, and half a tub of mascarpone in the fridge. It was one of those “let’s see what happens” moments — and what happened was a chilled, layered dessert that looked elegant yet felt like comfort food in disguise.
The beauty of a Blueberry Crumble Fool is in its contrast. You start with a base layer of buttery crumble — golden, crumbly, and just sweet enough to set the tone. It’s not there for decoration; it’s there to give you that satisfying crunch as your spoon breaks through the layers. On top of that sits the mascarpone, rich and velvety, lending a creamy indulgence that balances the tartness of the blueberries to come.
Now, the blueberry and yoghurt layer is where the freshness kicks in. I like blending fresh blueberries with thick, tangy yoghurt, which not only gives you that beautiful violet colour but also adds a refreshing lift that keeps the dessert from feeling too heavy. The yoghurt cuts through the richness of the mascarpone, and the blueberries add a fruity burst in every spoonful.
Of course, because we’re not here to do things halfway, the final flourish is a little spoonful of crumble sprinkled over the top — a cheeky nod to its baked cousin — and a scattering of fresh blueberries that glisten like tiny jewels. Serve it chilled, and you’ve got something that’s perfect for warm summer evenings, but just as delightful when you need a little winter pick-me-up.
One of my favourite things about serving Blueberry Crumble Fool in tall glasses is the drama of the layers. People eat with their eyes first, and when you place one of these on the table, there’s always a little pause before the first spoonful — that “do I ruin this work of art?” moment. The answer, of course, is yes. Absolutely. Dig in.
It’s also a surprisingly easy dessert to prepare ahead of time. You can make the crumble and blend the blueberry yoghurt in advance, then layer everything just before serving to keep the textures perfect. The mascarpone can be whipped with a little sweetness and stored in the fridge, ready to go. It’s low effort for high impact, which is my favourite kind of cooking.
Whether you serve it at a dinner party or just as a treat for yourself, Blueberry Crumble Fool is proof that simple ingredients, given a little love, can create something truly memorable. It’s indulgent yet fresh, familiar yet special — the kind of dessert that makes you smile before you’ve even taken a bite.

Made these as a surprise and they vanished in minutes. Never heard the family go so quiet. Total win.
The fresh blueberries on top were the perfect touch. They gave a little pop of freshness that tied the whole dessert together beautifully.
Light, fruity, and refreshing, but still indulgent enough to feel special.
Once you dig in, the combination of creamy mascarpone and tangy blueberries is perfection.
This dessert is a game-changer. It has all the comfort of a crumble but dressed up in a way that feels restaurant-worthy.
Just the right balance of tart and sweet.
The layers look so elegant in a tall glass — almost too pretty to eat.
I loved that you can prepare parts of it in advance. The crumble and compote kept well, and assembling was quick — ideal for entertaining.
As someone who doesn’t usually enjoy heavy desserts, this was perfect.
This is comfort food in fancy dress! It reminded me of classic crumbles from childhood but with a modern, lighter twist.
I loved the tang from the Greek yoghurt. It stopped the dessert from being too sweet and gave it such a refreshing finish.
The bright colours and fresh blueberries on top made it fun, and the flavour was sweet without being overpowering.
The compote makes this dish shine. It adds a richness that pairs so well with the yoghurt and mascarpone.
I normally prefer chocolate desserts, but this one won me over. The creamy mascarpone with the blueberry swirl was irresistible.
The tall glasses really elevate this dessert. The layers looked gorgeous on the table and got lots of ‘wows’ when I brought them out.
My children loved this.
I made this for a summer BBQ and it completely stole the show. Everyone loved how light yet indulgent it felt, and the compote gave it such a beautiful fruity depth.
This dish is deceptively simple for how impressive it looks.
I adored the balance of textures. The crunch of the crumble against the smooth mascarpone and silky blueberry layers was just heavenly.
