No-bake Marshmallow Slice

This No-bake Marshmallow Slice is another favourite of mine because of its delicious flavour and fantastic texture. Adapt the ingredients to what you love and make it your own in a few simple steps.

Three pieces of no-bake marshmallow slice are stacked on top of each and sit on a wooden board. The slices show the biscuit base, the textural marshmallow centre and the chocolate topping with a peanut butter drizzle.

Originally I called this recipe nougat slice but the more I think about it, it has much more of a marshmallow quality to it, so I have changed the name! It has a chocolate biscuit base, a soft marshmallow centre and a chocolate top, perfect for parties, afternoon tea or any occasion at all. So, follow me and let's whip up this fun slice.

Ingredient Tips for the No-bake Marshmallow Slice:

A wooden board sits on a table. It is filled with vintage bowls, spoons and jars that have slice ingredients in them. There is egg whites, caster sugar and cranberries in view. A vase of flowers is in the background with golden fairy lights.
  • Biscuits: I use chocolate filled Oreos but any store-bought chocolate cookies work.
  • Coconut: I prefer kokonati pūtī (desiccated coconut) in this recipe but if you like a chunkier texture, use shredded.
  • Butter: Melted butter or coconut oil can be used in the base.
  • Gelatine Powder: This little ingredient helps the cake to set and if you live in NZ, I prefer the Mrs Rogers brand.
  • Peanuts: Use dry roasted peanuts or any of your favourite nuts.
  • Cranberries: Dried cranberries give a sweet and sharp flavour but they can be omitted or swapped out for any of your favourite dried fruit.
  • Peanut Butter: This creates a delicious savoury note to the slice but it can be omitted or swapped for Nutella, Biscoff or any nut butter.
  • Chocolate: I prefer tiakarete parauri (dark chocolate) because it balances the sweetness of the filling but use your favourite chocolate.

EXPERT TIPS:

Be careful when working with the sugar syrup. This māngohe (marshmallow) needs hot, boiling syrup poured in to a meringue so definitely keep little hands away from the marshmallow making part.

This is a very adaptable recipe that can have ingredients removed and swapped. Choose what flavour profile you want and then fold it in to the merenge (meringue) base.

STEP BY STEP INSTRUCTIONS FOR THE NO-BAKE MARSHMALLOW SLICE:

Note: The full recipe card with the full list of ingredients, instructions and step by step video are found at the bottom of this page.

A wooden board sits on a table, on the board is a vintage silver bowl that has chocolate Oreo cookies in it. Behind that is a silver cup of coconut and a small plate of chopped butter. Golden fairy lights glow in the background.

1. Prepare the Tin:

Prepare a 20 cm square baking tin with baking paper. 

2. Process the Biscuits:

Add the pihikete tiakarete (chocolate biscuits) and kokonati (coconut) in to the tāwhirowhiro (food processor), then turn in to a fine crumb. If you don't have a food processor you can crush the biscuits in a mortar and pestle or with a rolling pin. 

3. Mix in the Butter:

Add the pata kua rewaina (melted butter) or hinu kokonati kua rewaina (melted coconut oil) and process for 30 seconds.

4. Press the Base in to the Tin:

Add the crumb to the prepared baking tin and press the mixture in as firmly as it can go. Chill it in the fridge while you make the māngohe (marshmallow).

A white bowl is sitting on natural fabric. It has a meringue inside it that is being whipped by a white hand beater.

5. Bloom the Gelatine:

Add the paura tetepe (gelatine powder) and wai (water) in to a heatproof cup. Stir until combined and leave for 5 minutes to bloom.

6. Toast the Coconut:

You can skip the toasting part if you don't want but it does add beautiful flavour. 

Add the kokonati (coconut) to a pot or frying pan and toast over medium heat until golden. 

Remove it from heat and add to a plate to cool slightly. 

6. Prepare the Egg Whites:

Add the kahu hēki (egg white) and kirīmi tāta (cream of tartar) to a heatproof bowl.

Whip them on medium-high speed until soft peaks form and set it aside.

7. Make the Sugar Syrup:

Add huka one (caster sugar), tote (salt) and wai (water) to a pot. 

Boil over high heat until it reaches 140 °C.

8. Melt the Bloomed Gelatine:

As the sugar syrup is heating up, melt the bloomed gelatine in the microwave for 20 seconds.

9. Combine the Egg Whites and Sugar Syrup:

Slowly pour the hot sugar syrup into the whipped meringue and whip on high for a minute or so. 

Then pour in the melted gelatine as you continue to whip for 5-7 minutes. Add in the wanira around the three minute mark.

Melted chocolate is in a glass bowl with a wooden spoon in it.

10. Mix all the Ingredients together:

Once the meringue has stiff peaks, fold in the kokonati (coconut), pīnati (peanuts) and karanipere (cranberries). Then, fold through the pata pīnati (peanut butter). 

11. Add the Mixture to the Tin:

Pour the māngohe (marshmallow) on top of the cooled base and refrigerate for 15 minutes to start the setting process. 

12. Prepare the Chocolate Topping:

Chop the tiakarete parauri (dark chocolate) in to chunks. Then add the chocolate and noni (oil) in to a small pot. Gently melt it on the stove over super low heat as you gently stir. 

Once it is smooth, pour it gently over the slightly chilled slice. Give the tin a shake to smooth out the chocolate. 

A close up shows the no-bake marshmallow slice with dark chocolate on top that is still wet. On top is rows of dots of peanut butter that have been piped with a star tip. Naomi has just finished piping a dot and the peak of the peanut butter is seen.

13. Add the Peanut Butter Decoration (Optional)

Immediately (before the chocolate sets), pipe dots of the pata pīnati (peanut butter) in little lines all over the slice. It is easiest in a piping bag with a small star tip. 

Once you have added all the dots, gently drag a kebab stick through each one to get a simple design. 

Again, this is just an option. You can leave the slice with plain chocolate or sprinkle it with chopped nuts or freeze dried fruit too.

A flat lay shows a no-bake marshmallow slice that has been cut in to pieces to reveal the chocolate topping with the peanut butter design. Two slices has been flipped over to reveal the layers of biscuit base, marshmallow and chocolate topping. A candle burns in the corner.

14. Refrigerate:

Set in the fridge for an hour or so. 

Store the Slice:

Keep this slice stored in the fridge in a sealed container. It will last for up to a week this way.
