A simple, no-bake slab icebox cake layered with whipped cream, buttery biscuits, and fresh summer berries. Perfect for hot days and summer gatherings, this dessert is quick to prepare and refreshingly delicious.

Ingredients

  • Butter cookies or graham crackers (about 300g / 10.5 oz)
  • Unsalted butter (100g / 7 tbsp), melted
  • Heavy whipping cream (480ml / 2 cups), cold
  • Powdered sugar (60g / ½ cup), sifted
  • Vanilla extract (1 tsp)
  • Fresh summer berries (600g / 21 oz total) – strawberries (hulled and sliced), blueberries, raspberries, blackberries
  • Lemon zest (1 tsp)
  • Honey or maple syrup (2 tbsp), optional

Instructions

  1. Crush the butter cookies into fine crumbs using a food processor or by placing them in a zip-top bag and smashing with a rolling pin.
  2. Combine the crumbs with melted butter until the mixture resembles wet sand.
  3. Press this evenly into the bottom of your baking dish, creating a firm and even layer. Chill in the fridge for 10 minutes to set.
  4. In a chilled mixing bowl, beat the cold heavy whipping cream with powdered sugar and vanilla extract until soft peaks form. Be careful not to overbeat.
  5. Spread half of the whipped cream evenly over the chilled cookie base.
  6. Scatter a generous layer of mixed berries on top, pressing them lightly into the cream.
  7. Repeat with another layer of whipped cream, followed by a final layer of berries.
  8. Sprinkle lemon zest over the top and drizzle with honey if using.
  9. Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight.
  10. Slice into bars or squares using a sharp knife dipped in hot water for clean cuts. Serve chilled, garnished with extra fresh berries or a sprig of mint if desired.

Notes

Keep all bowls and cream chilled before whipping to achieve soft peaks. Press cookie base firmly but gently for best texture. Drain juicy berries briefly to avoid sogginess. Slice with a sharp knife warmed under hot water for clean cuts. For dairy-free, use coconut whipped cream; for gluten-free, use gluten-free cookies or almond flour biscuits.
