Blackberries are a jewel of the fruit world — sweet, tangy, and bursting with juice. These blackberry almond crumble bars are a celebration of everything we love about berry season.

A buttery oat shortbread crust lays the foundation, while the filling brings a fruity punch of blackberries thickened gently with sugar and lemon juice. Topped with a golden, crunchy almond-scented crumble, each bite balances richness with bright, juicy flavour.

These bars are perfect for casual brunches, afternoon snacks, or as a rustic dessert served with a scoop of vanilla ice cream. They’re easy to prepare and store beautifully, making them an ideal treat to bake on the weekend and enjoy throughout the week.

Whether you’re using handpicked blackberries or frozen ones from the freezer, this recipe highlights their bold flavour in a way that’s both comforting and impressive. You’ll love how the textures play together — soft, jammy filling and crisp, buttery crumble in every bite.

Tips til at lave de bedste Blackberry Crumble Bars

Brug pergament for nem fjernelse og rene snit.
Friske eller frosne brombær fungerer - optø og dræn, hvis de er frosne.

Spring ikke over mandelekstrakten - det tilføjer en fantastisk smagsdybde.
Lad stængerne køle helt af, før de skæres i skiver.
Brug citronsaft til at lysne bærsmagen.
For ekstra crunch, tilsæt hakkede mandler til toppen.
Fordoble opskriften på en 9x13 pande, hvis du fodrer en flok.
Opbevares i en lufttæt beholder i op til 4 dage.
Server let lun med is til en hyggelig dessert.
