Ingredients
  

  • 1 can sweetened condensed milk (14 oz / 395g)
  • 150 g salted butter, cubed
  • 350 g high-quality white chocolate, chopped
  • 250 g plain biscuits/cookies (Marie, Shortbread, Nilla Wafers), roughly crushed
  • 100 g white chocolate chips
  • 1 cup freeze-dried raspberries

Equipment

  • 8-inch square baking tin
  • Parchment Paper
  • Microwave-safe mixing bowl
  • Spatula
  • electric mixer (optional)
  • Sharp knife

Method
 

  1. Line an 8-inch (20cm) square tin with parchment paper, leaving overhang on two sides for easy lifting.
  2. In a large microwave-safe bowl, add cubed butter and sweetened condensed milk. Microwave for 1 minute on high, then stir. If butter has not fully melted, microwave for an additional 30 seconds.
  3. Add chopped white chocolate to the hot condensed milk mixture. Let sit 30 seconds, then stir until smooth. Microwave in 20-second bursts if needed, stirring between each.
  4. For an ultra-smooth fudge base, beat with an electric mixer for 1–2 minutes to fully emulsify the butter and chocolate.
  5. Fold in crushed biscuits and white chocolate chips. Then gently fold in freeze-dried raspberries—crushing a few slightly to distribute color, but leaving most whole.
  6. Press mixture firmly into the prepared tin, smoothing the top. Refrigerate for 2–3 hours until completely firm.
  7. Lift the block out using the parchment handles. Slice into 16 squares using a sharp, warm knife for clean edges. Serve chilled and store in the refrigerator.

Notes

Let the mixture cool for 5 minutes before adding mix-ins to prevent premature melting. Warm a knife under hot water and wipe dry between slices for clean, professional edges.
