Ingredients You’ll Need

The ingredients for this slice might sound simple, but each plays an essential role. The Girl Guide biscuits give a sturdy yet crumbly base, while dried cranberries and pistachios bring bursts of flavor and texture. Choosing good-quality white chocolate for the topping really makes a difference too, and those freeze-dried raspberries add a splash of color and tang.

• Sweetened condensed milk: This creates the rich, chewy base, giving moisture and sweet creaminess without needing butter alone.
• Butter: Adds richness and helps bind the base ingredients together when melted.
• Girl Guide biscuits: Finely crushed, these traditional biscuits provide a crumbly texture that’s perfect for the base. Feel free to swap with digestives if needed.
• Dried cranberries (craisins): These sweet, tart gems are a highlight—don’t skimp here, as they add wonderful bursts of flavor.
• Pistachios: Chopped and slightly toasted, they bring a lovely crunch and nutty taste that balances the sweetness.
• White chocolate: Melts into a silky, smooth topping that sets firm but soft under your fingers.
• Vegetable oil: Helps thin the white chocolate for a perfect glossy finish.
• Freeze-dried raspberries (optional): Crushed on top for a pretty, tangy finish that cuts through the sweetness.

Variations

One of the best things about the Cranberry and Pistachio Slice with White Chocolate and Raspberries Recipe is how forgiving it is to variations. I love tweaking it depending on what’s on hand or who I’m serving it to.

• Nut substitutions: I’ve swapped pistachios for almonds or walnuts when I ran out—and it still tastes fantastic.
• Chocolate variety: Sometimes I use milk chocolate topping or mix dark chocolate with a bit of white for a marbled effect, which my family loves.
• Fruit swaps: Dried cherries or blueberries work well if cranberries aren’t your favorite.
• Dietary tweaks: For a dairy-free version, try coconut condensed milk and vegan butter alternatives—you’ll lose a touch of richness but keep the slice delicious.

How to Make Cranberry and Pistachio Slice with White Chocolate and Raspberries Recipe

Step 1: Prepare the Base Mixture

Start by gently melting the butter in a small saucepan or microwave. Once melted, stir in the sweetened condensed milk until fully combined. Next, tip the finely crushed Girl Guide biscuits into a large mixing bowl along with the dried cranberries and pistachios—make sure your pistachios are roughly chopped for a nice bite. Pour the butter-condensed milk mixture over the dry ingredients and mix thoroughly until everything is well coated and sticky. This step is where your base really takes shape, so get your hands in if you want to make sure every crumb is perfectly covered.

Step 2: Press the Base into the Pan

Line a small slice tin or square pan (around 20×20 cm/8×8 inch) with baking paper, letting some excess hang over the sides for easy removal later. Then firmly press your base mixture evenly into the pan. A trick I’ve learned is to use the bottom of a flat glass or spoon—you want the base compacted tightly so it holds together well once chilled. Pop this into the fridge while you prepare the topping to let it set a bit.

Step 3: Make the White Chocolate Topping

Break the white chocolate into chunks and place it in a heatproof bowl with the tablespoon of vegetable oil. Melt gently over a double boiler or in short bursts in the microwave, stirring frequently so the chocolate stays smooth and glossy. The oil helps everything stay shiny and easier to pour. Once melted, pour the chocolate evenly over the chilled base in the pan. If you want that beautiful pop of color and tartness, sprinkle the crushed freeze-dried raspberries on top immediately before the chocolate sets.

Step 4: Chill Until Set and Slice

Refrigerate the slice for at least two hours or until the chocolate is fully set and firm to the touch. When you’re ready to serve, use the parchment paper to lift the slice out of the pan. Using a sharp knife warmed under hot water and wiped dry, cut the slice into neat squares or rectangles. Warming the knife with each cut prevents cracking and helps keep your slice looking clean.

How to Serve Cranberry and Pistachio Slice with White Chocolate and Raspberries Recipe

Garnishes

I typically stick with a sprinkle of extra crushed freeze-dried raspberries on top for an elegant touch and a slight tart bite that complements the sweetness so well. Sometimes I add a few whole pistachios or fresh raspberries to make it look extra inviting, especially when I’m serving for guests.

Side Dishes

This slice pairs beautifully with a simple cup of tea or coffee—its richness is balanced perfectly by a hot, slightly bitter drink. I’ve also served it alongside fresh fruit salad for an afternoon tea spread, which highlights the fresh fruit flavors inside the slice.

Creative Ways to Present

For special occasions, I like arranging the slices on a pretty platter with edible flowers or mint leaves scattered around. Another favorite is to serve individual slices on dessert plates drizzled with a raspberry coulis or a dusting of icing sugar to add a little elegance.

Make Ahead and Storage

Storing Leftovers

I store leftover cranberry and pistachio slices in an airtight container in the fridge, where they keep well for up to a week. This keeps the white chocolate topping firm and the base deliciously chewy. I find that storing them this way also makes the flavors meld beautifully over a day or two.

Freezing

I’ve frozen this slice successfully by cutting it into portions first and wrapping each piece tightly in cling film followed by foil. When you’re ready to enjoy, just thaw in the fridge overnight. The texture remains surprisingly good, though the white chocolate may lose a little of its shine.

Reheating

I usually don’t reheat this slice since it’s best served chilled, but if you want to soften it slightly, just leave it at room temperature for 15-20 minutes. This brings out the flavors without melting the white chocolate too much.
