How to make Pistachio and Cranberry Marshmallow Slice
Ingredients:
- 110g pistachio kernels, coarsely chopped
- 100g dried cranberries, coarsely chopped
- 4 Weet-Bix biscuits
- 65g shredded coconut
- 150g self-raising flour
- 100g brown sugar
- 200g butter, melted
- 250ml thickened cream, whipped
- 1 tbsp shredded coconut, extra
- 220g caster sugar
- 3 tsp gelatine powder
- 1 tsp vanilla extract
- Pink food coloring gel
Directions:
Step 1: Preheat your oven to a sizzling 180 degrees C (160 degrees C if you’re rollin’ fan forced). Grease a 5cm-deep and 20 x 26cm roasting pan to ensure your creation slides out as smoothly as a first-class upgrade and line it with baking paper–your future self will thank you! Grab your trusty bowl and combine the pistachios and cranberries, saving a couple of tablespoons for that Instagram-worthy garnish later.
Step 2: Time to crush those Weet-Bix biscuits! Channel your inner warrior and pulverize them into a fine crumb in a separate bowl. Toss in the shredded coconut, self-raising flour, brown sugar, and your chopped pistachio-cranberry mixture. Mix it all together like you’re summoning the culinary spirits, then fold in the melted butter, creating a luscious and boisterous blend. Spread this heavenly mixture into your prepared pan and press down firmly. Bake for 15 minutes or until it’s gloriously golden and tempting. Let it cool while you steal a moment to admire your baking brilliance.
Step 3: On to the pièce de résistance: the marshmallow topping! In a saucepan, combine caster sugar and 125ml of water. Over low heat, melt that sugar like snow on a warm summer day, then crank up the heat until it reaches a bubble frenzy.
Step 4: In a small bowl, soak the gelatine in 80ml of water like it’s sinking into a soothing spa day. Then, add it to your bubbling sugar mixture and stir until it’s all blended as blissfully as your favorite road-trip playlist. Allow this to cool slightly while you dance a little jig.
Step 5: Transfer the gelatine mixture to a stand mixer and add in that fragrant vanilla. Whisk on low for 2 minutes, ramp it up to medium for 10 minutes, and turn it up to high for another 5 minutes—you’re crafting magic, darling! Add in a tantalizing swirl of pink food coloring gel and pour this fluffy wonder over your Weet-Bix base. Slide the whole masterpiece into the fridge for about 6 hours until it sets.
Step 6: Once it’s beautifully firm and tantalizing, slice it into squares and pipe a dollop of whipped cream on top. Sprinkle that reserved cranberries and coconut over like confetti at the end of a celebration—because, let’s face it, every bite should feel like a little party in your mouth!
