Just A Mums Pineapple Lump Slice

 

No bake slices are always a hit, they are so simple to make, no fussy techniques an definitely delicious. This recipe isn’t a new one, but it is definitely a popular one! I first uploaded this in 2014 and it has been made often.

There are several brands now that make pineapple lumps, so you can easily pick up a few bags in the supermarkets.

How to Make No Bake Slice

 

I froze the pineapple lumps first to make it easier to cut them up – they go really hard and brittle so will cut easily with a sharp knife or in the food processor. I prefer to slice mine as I think it gives larger chunks, and with them being frozen this is quite simple to do.

Be sure to reserve some for the topping – the topping can be cut finer. 

Ingredients for No Bake Slice

 

All no bake slices are very similar, the base for this recipe is simply butter and condensed milk, combined together with malt biscuits and the frozen pineapple lumps it makes for a very simple recipe.

No Bake Slices

 

I have a few easy tips for how to make sure your slice looks perfect every time. This mostly has to do with the topping, which in this case is a block of milk chocolate. 

Melted Chocolate Poured over Slice

 

The easiest way to melt chocolate is in the microwave, you can definitely do it over a bain marie on the stove top but if you do have a microwave do it in there, in a microwave safe bowl add the broken up chocolate melt in 20-30 second bursts until the chocolate is completely smooth.

Then add a small teaspoon of oil to this, canola or coconut oil is fine. This ensures when you cut into your slice the topping does not crack. I have one other tip too!

A whole slice before cutting

 

Remove the slice from the fridge at least 30 minutes before you wish to cut into it. This will ensure that the topping is not rock hard and you can slice cleanly though it. Also I recommend a nice sharp knife, and I clean it with a damp cloth, then dry between each slice so that you can have clean tidy slices each time.

Of course you can cut it any way you choose! But this is just how I have found works best for me. 

And now for a bit of history – so please make yourself comfortable and feel free to take notes and thank Wikipedia – the holy grail of knowledge…..

The history of Pineapple Lumps

 

“The first Pineapple Lumps were made by the Regina Confectionery Company in Oamaru around 1952-54. Charles Diver, the confectionery chef and floor production manager at Regina, who would later create other classic kiwi sweets, was given the task of using up waste product from other lollies of the time. One sweet in particular, an early version of the chocolate fish with a banana flavoured marshmallow middle, had the most left overs.

Pineapple Lumps were originally called Pineapple Chunks, but the name was changed in the early 1960s to give them a more unique and original title”

The original Pineapple Chunks are now being manufactured again by Regina Lollies, Pineapple Lumps are available at all Supermarkets under their own brand, Pascalls and other brands across New Zealand and Australia. 

Ooh who knew?? Nothing like knowing your favourite lolly is made from waste products!

Onto the Recipe for Pineapple Lump Slice

Pineapple Lump Slice by Just a Mum

Pineapple Lump Slice

Yield: 24
Prep Time: 15 minutes
Cook Time: 5 minutes
Additional Time: 4 hours
Total Time: 4 hours 20 minutes

Delicious and decadent, this Pineapple Lump No Bake Slice is very simple to make and everyone will love it!

Ingredients

  • 280 grams Pineapple Lumps, 2 bags, Frozen (including half cup for topping)
  • 1 x 250g packet Malt Biscuits
  • 125 grams Butter
  • 1 Cup Condensed Milk – 300g (nearly a whole tin – but not quite, use the rest for salad dressing!)
  • 190 grams Milk Chocolate
  • 1 teaspoon Oil (optional)

Instructions

  1. Freeze the 2 Bags of Pineapple Lumps overnight or until hard
  2. Line a slice tin (or 25cm square cake tin) with baking paper and set aside.
  3. Crush the biscuits in a food processor, you can also pulse the pineapple lumps in here as well but I prefer to chop them by hand for bigger chunks - but this way quicker!
  4. Cut the frozen Pineapple Lumps into small pieces (you can reserve half a cup for the topping if you desire)
  5. Melt the butter and condensed milk in a large saucepan on low heat until melted and mixed together well, alternatively do this step in the microwave.
  6. Pour the pineapple lumps & biscuits mixture into the butter/condensed milk mixture and combine well
  7. Spoon the biscuit mixture into the slice tray and press down very firmly using the back of a large spoon or clean hands until tightly packed and smooth.
  8. Melt your chocolate in the microwave with 10-20 second bursts, stirring in between until completely melted or you can use a double boiler.
  9. If using add a teaspoon of oil to the melted chocolate and blend well
  10. Pour the chocolate onto the slice and using the back of a spoon spread chocolate evenly over the slice.
  11. Give the slice pan a jiggle to settle the chocolate evenly
  12. If you reserved some frozen pineapple lumps, slice into small pieces sprinkle these over the top of the slice
  13. Place in the fridge for at least two hours (preferably overnight).
  14. Take the slice out of the fridge and leave for 20 minutes before slicing (this way your chocolate will be less likely to crack).
  15. Cut the slice into squares.
  16. This slice will keep in an airtight container in the fridge for at least 5 days (but lets face it – it won’t last that long anyway!)

    Hi,

    I’m wondering, is it two bags of 280g of pineapple lumps or two bags equivalent to 280g?

      No dumb questions here! The reason I freeze the pineapple lumps is that it makes it really easy to cut them, otherwise they can be chewy and sticky and hard to cut. They also do not melt into the mixture as much.

    Pineapple chunks are my 87 year old mothers favourite sweet and she always has a lolly jar filled with them in her loungeroom. She still loves to bake so I am going to send this recipe to her as an alternative to the Mars Bar slice she always makes. Thank you ?

    Hi!

    Just made this slice – the tastes I’ve had so far are delicious!

    One thing I’ve found difficult is slicing it – the pineapple lumps stick to the knife, and get pulled out of the slice every time I cut it into pieces? Any tips?

      Hi, I use a very sharp large knife, slicing it straight down when it is out of the pan, but another way it’s to use a hot knife, so run it under hot water then dry the knife and slice each time you cut into it? They can be sticky but if it’s been chilled for long enough it should be ok to slice this way. Let me know how you get on. ?

    I LOVE pineapple lumps. I will definately try this recipe. Tell me, do you have the recipe for making salad dressing our if the condensed milk?

    Reply

    • justamumnz says

      My Mum makes salad dressing this way all the time, perfect for people who cannot tolerate normal mayo. It is simply condensed milk and malt vinegar. As far as I can tell no magic measurements. Add the condensed milk to a small bowl or cup, and add small amounts of malt vinegar until you get the desired taste – not too sweet, not too vinegary! Gosh, that certainly sounds scientific doesn’t it! She usually uses about half a cup of condensed milk to a few TBSP of vinegar. But if you only have a small dash left just add dashes accordingly – so so yummy with salad etc.

    Two very useful public comments following your recipe are:

    1. “Put the frozen Pineapple Lumps in a freezer bag and smash them with a rolling pin. They’ll break up nicely and not too small.”

    2. “If u add a small amount of oil to your chocolate it wont crack and cutting its easy.”

    Please include similar tips in your recipe.

    Looks sooo yum!!!! Want to try make this but am also interested on how I could make this gluten free also? Any idea would be much appreciated appreciate I’m new to gluten free baking??

    Reply

    • justamumnz says

      Hi Kara, hmm gluten free, without knowing too much about it the thing I would look is changing the biscuits for a gluten free version – any plain biscuit similar to a superwine or malt biscuit would be great – or even a chocolate chip might be fun! Then check the other chocolates/pineapple lumps to ensure they are gluten free also and you are away! Have a play around and let me know how you get on. Once you have the right biscuits you can make lolly cake, marshmallow slice & also clinkers slice found on my Sweet Treats page. Thanks for your question 🙂
