This blackberry fool is a lazy-day British dessert that looks fancy but couldn't be easier. Ripe blackberries get cooked down into a glossy purple puree, then swirled through whipped cream and yogurt so every spoonful is streaky and marbled. Serve it with buttery hazelnut biscuits for dunking and you have a no-fuss showstopper.

Ingredients

  • 1/3 cup hazelnuts
  • 1 stick (1/2 cup) butter, softened
  • 3/4 cup granulated sugar (for biscuits)
  • 1 tsp grated lemon zest
  • 1 1/4 cups all-purpose flour
  • 1/2 tsp baking powder
  • about 5 cups (1 1/3 lb) fresh blackberries
  • 1/3 cup plus 2 tbsp granulated sugar (for the fool)
  • 1 tbsp lemon juice
  • 1 1/4 cups heavy cream
  • 1/3 cup plus 1 tbsp plain yogurt
  • fresh mint leaves, to garnish

Equipment

  • Two baking sheets
  • Parchment paper
  • Nonstick saucepan
  • Fine mesh sieve
  • Electric mixer
  • Mixing bowls

Instructions

  1. Heat your oven to 400 degrees F and line two baking sheets with parchment paper so the biscuits release cleanly.
  2. Scatter the hazelnuts on one sheet and toast for 6 to 8 minutes, until golden and fragrant. Watch them closely because they go from toasty to burnt fast. Tip onto a board and let cool.
  3. In a large bowl, beat the softened butter with 3/4 cup sugar until pale and creamy, about 2 minutes, so the biscuits bake up tender.
  4. Roughly chop the cooled hazelnuts and add them to the butter mixture along with the lemon zest, flour, and baking powder. Stir until it clumps into a soft dough, using your hands to bring it together if needed.
  5. Divide the dough into 24 pieces, roll into balls, and space them well apart on the sheets since they spread as they bake.
  6. Flatten each ball to about 1/2 inch thick and bake one sheet at a time for 12 minutes, until very pale golden. They'll be soft coming out but firm up as they cool on the tray, so leave them be.
  7. Rinse the blackberries and add them to a nonstick saucepan with 1/3 cup plus 2 tbsp sugar and the lemon juice. Warm gently for 2 minutes, until the berries soften and start giving up their juice.
  8. Set aside 12 whole blackberries for decorating, then simmer the rest gently for about 15 minutes, stirring often, until very soft and jammy.
  9. Press the cooked berries through a fine sieve set over a bowl, pushing with the back of a ladle to squeeze out every bit of puree. Discard the seeds and let the puree cool completely (you'll have about 1 1/3 cups).
  10. Whip the heavy cream and yogurt together with an electric mixer just to soft peaks. Stop early, because the acidic fruit will thicken it further once combined.
  11. Pour the cooled puree into the cream and fold once or twice only, so it stays boldly marbled rather than fully mixed. Taste and add a little more sugar if the berries were tart.
  12. Spoon into individual glasses or one big bowl, top with the reserved berries and a few mint leaves, and serve with the hazelnut biscuits.

Tips from the kitchen

  • Cool the blackberry puree fully before folding it into the cream, or the warmth will deflate your soft peaks.
  • Fold gently and just a couple of times. The pretty marbled streaks are the whole point.
  • Stop whipping the cream at soft peaks since the fruit thickens it more once combined.

Make it your own

  • Swap blackberries for raspberries, blueberries, or a mix of summer berries.
  • Use crushed toasted almonds or pecans in the biscuits if hazelnuts are hard to find.
  • Fold in a splash of vanilla or a spoonful of Greek yogurt for extra tang.

Storing & make-ahead

Store the biscuits in an airtight tin for up to 5 days. The fool keeps covered in the fridge for up to 2 days, though it looks freshest the day it's made. Assemble in glasses just before serving.

Good to know

Can I make the fool ahead?
Yes. Make the puree up to 2 days ahead and store it chilled, then whip the cream and fold everything together a few hours before serving.
Can I use frozen blackberries?
Absolutely. Cook them straight from frozen, adding a couple extra minutes of simmering to reduce the extra liquid.
Why is my cream runny?
You likely overwhipped or underwhipped it. Aim for soft peaks, since the acidic berries firm things up once folded in.
Do I have to make the biscuits?
No. The fool is delicious on its own, but the crisp hazelnut biscuits add crunch and make it feel like a real dessert.
