Ingredients

• 250 g Marie biscuits
• 120 g butter
• 1/2 cup condensed milk
• 2 Peppermint Crisp bars, chopped or crushed

That’s all you need for a rich, minty fridge slice.

Instructions

Line a square baking tin with parchment paper, leaving some overhang for easy removal later.

Crush the Marie biscuits into fine crumbs using a food processor or rolling pin.

Melt the butter and add it to the crushed biscuits in a mixing bowl. Stir until evenly combined.

Pour in the condensed milk and mix until a thick, sticky mixture forms.

Fold in the crushed Peppermint Crisp bars, distributing them evenly throughout.

Press the mixture firmly into the prepared tin, smoothing the surface with the back of a spoon or spatula.

Refrigerate for at least 2 hours, or until completely set.

Once firm, lift out using the parchment paper, slice into squares or bars, and serve chilled.

Texture and Flavor

This biscuit slice is soft and fudgy with bursts of mint chocolate in every bite. The biscuits provide gentle structure, while the condensed milk and butter create a creamy, melt-in-the-mouth texture. Peppermint Crisp adds crunch and freshness, balancing the sweetness beautifully.

It’s rich without being overwhelming and slices cleanly once fully chilled.

Helpful Tips for Perfect Results

Crush biscuits finely but leave a few small chunks for texture.

Press the mixture firmly into the tin so the slice holds together well.

If the mixture feels dry, add a tablespoon of extra condensed milk.

Use a sharp knife for neat slices, wiping the blade between cuts.

Keep refrigerated until serving for best texture.

Easy Variations

This recipe is wonderfully flexible. Try one of these ideas:

Chocolate Topped Slice
Spread melted milk or dark chocolate over the top before chilling.

Extra Mint Version
Add a few drops of peppermint essence for stronger mint flavor.

Nutty Crunch Slice
Mix in chopped almonds or peanuts.

White Chocolate Peppermint
Fold in white chocolate chips for extra sweetness.

Layered Slice
Add a thin chocolate layer on top for a more decadent finish.

Each variation uses the same base method while giving you new flavor combinations.

Storage and Make-Ahead

Peppermint Crisp Biscuit Slice stores beautifully.

Keep in an airtight container in the refrigerator for up to five days.

It also freezes well for up to one month. Thaw in the fridge before serving.

Because it holds its shape and tastes even better chilled, it’s perfect for preparing ahead of parties or busy weeks.

Serving Suggestions

Serve chilled for the best texture. This slice pairs wonderfully with tea, coffee, or hot chocolate and looks great on dessert platters.

For presentation, drizzle melted chocolate over the top or sprinkle extra crushed Peppermint Crisp before slicing.

It’s also ideal for lunchboxes, bake sales, and casual gatherings.
