DON’T LOSE THIS RECIPE. PIN Trick or Treat Rocky Road FOR LATER…

Halloween Rocky Road with a dark secret…
Looking for something a bit different for your Halloween Party? Get a little scared with this Halloween Rocky Road. It may look innocent, but inside the inviting, colourful, exterior lurks a dark secret. This is no ordinary Rocky Road… It’s a Trick or Treat Roulette Rocky Road. And its secret is set to freak out anyone who dares to eat a slice.
The recipe makes at least 16 seductive squares of delicious chocolate-M&M-Marshmallow loveliness. But when you gamble on temptation, you may just get a shock! Beneath the innocent surface of one of these blocks hides an unexpected chilli-chocolate surprise… For the (un)lucky person who gets it, they’re in for a spicy scare.




How to serve Trick or Treat Rocky Road
If you’re having a party, set the Halloween Rocky Road on the table with a big sign saying ‘Face The Fear’ or ‘Are YOU Brave Enough?’. The party-goers will wonder about the sign. You could explain… or not… depending on how mischievous you feel. Then watch as slice after slice is tentatively nibbled. Who will get the unexpected chilli-chocolate ‘trick’?
Alternatively, you could make a game of eating trick or treat rocky road. Spin a bottle to decide who gets the next potentially scary slice. Or put numbers in a hat to decide the order in which people take a slice and then eat them all together.




Making Trick or Treat Rocky Road ‘Friendly’ for young children
Trick or treat Rocky Road is perfect for teenage or adult parties. But even I would be reluctant to give it to littlies. I’m not sure they’d fully get the trick and the last thing you need is tears on Halloween. But you will know your guests and whether chilli is suitable for anyone who might get the scare.
No worries though… It can also be made to be fun for younger kids too. Maybe pop in a chocolate that has been infused with lavender or Parma violets. Or add a piece of Turkish delight, a jelly ‘eye’ or a glacé cherry for a more oogly or unexpected texture.




Is Halloween Rocky Road easy to make?
Oh yes! This Halloween Rocky Road recipe is a simple, no bake, throw together job. So, even with short notice, it can be ready for party night.




Do I have to use the specific Sweets and Biscuits listed?
No. Halloween Rocky Road is pretty versatile on the sweet front. I made mine with a quick bag of M&Ms for colour (just make sure you choose a variety that is gluten free). But any colourful Halloween-friendly sweets will work.
It’s the same with the biscuits too. This version was made using gluten free Rich Tea biscuits from Schaar. But if you and your guests can all eat gluten, ordinary Rich Tea biscuits are fine. Or use an alternative plain, fairly dry biscuit like Malted Milk or Marie biscuits. Different supermarkets offer different ‘free from’ options.

Halloween Rocky Road (with a Trick or Treat surprise)
Key equipment
- Mixing bowls – heat proof (microwavable)
- microwave or hob and saucepan
- fridge
- 8 inch/20 cm square baking tin
- cling film
- spoon
- cutting board
- large sharp knife
Ingredients
Rocky Road Base
- 150 g butter (or DF alternative) cut into cubes
- 200 g dark chocolate chopped
- 50 g golden syrup
- 20 g cocoa powder
- 200 g gluten free rich tea biscuits
- 80 g M&Ms (+ a few extra for decoration) or alternative colourful sweets (Make sure the M&Ms are the GF varieties).
- 50 g mini GF marshmallows placed in the freezer for 2 hours ahead of making
- ½ tsp vanilla extract
Chilli Trick (see NOTES)
- 1 cube dark chocolate
- 1 pinch chilli powder or more/less depending on how hot you want the ‘trick’ to be
Decoration
- 80 g white chocolate
- orange food colouring paste
Instructions
Chilli Trick (prepare first)
- Place the chocolate cube into a tiny small, microwavable dish or onto a piece of baking paper.
- Heat for a few seconds in the microwave (medium setting) until softened/melted.
- Add the chilli powder and mix through thoroughly. Form into a blob on a small piece of baking paper.
- Place in the fridge to set.
Rocky Road
- Prepare an 8 inch square cake tin by completely lining with cling film (so that it hangs over the sides) and on top of this, base-line with non-stick baking paper.
- Place the butter, dark chocolate, golden syrup and cocoa powder into a large, microwaveable/heatproof bowl.
- Microwave on medium heat at 30 second bursts stirring between each, to melt all the ingredients until completely blended and smooth. (Alternatively, heat in a saucepan over a low heat, stirring frequently).
- Set aside and allow to cool slightly.
- While cooling, prepare the biscuits by either breaking into smallish pieces with hands or bashing (in a clean food bag and using a rolling pin). Alternatively, cut into thin sticks with a sharp knife. Set aside.
- In a large bowl, mix together the chocolate mixture, biscuit pieces, M&Ms, frozen mini marshmallows and vanilla extract.
- Tip the mixture into the cake tin and push to the sides, so that it is evenly spread. It will look quite lumpy on the surface.
- Mentally divide the square into a grid 4 x 4 and using a teaspoon, carefully scoop up a little mixture from one of the grid pieces and place the chilli trick into the mixture, replacing the scoop on top to hide the trick.
- Place the rocky road in the fridge for a couple of hours until fully set.
- When set, remove the Rocky Road from the tin and peel off the clingfilm and baking paper.
- Place on a clean cutting board.
- Melt the white chocolate in a small microwavable (I use glass) bowl, on medium heat at 30 second bursts, stirring between each until melted and smooth (or place the bowl over a saucepan of simmering water, stirring frequently).
- Add a little food colouring paste to the chocolate and mix thoroughly.
- While still runny, drizzle the (now orange) white chocolate over the Rocky Road randomly with a spoon.
- While the chocolate decoration is still unset, top with a few extra M&Ms and mini marshmallows.
- Leave to set in the fridge.

PS Your photography is awesome.
Thank you SO much Kathleen. That’s fantastic.
And thank you too all of you for hosting such a great link-up.
This is such a fun recipe. I hope it will make Halloween a little more fun this year with all the restrictions x
You are very inventive and this is a very moreish and inviting bake! This year I celebrated Halloween for the very first time as I was always in Italy the previous years.
Thank you Alida. Wow…. first Halloween?! Hope it was fun for you all! x
OOh I love the roulette concept of eating this! The colours are just wonderful too. Thanks so much for joining in with #BakeoftheWeek. New roundup now live x
Thanks Helen. You're welcome xx
This is so nice and colourful!
Thank you x
This is such a fantastic idea! And the rocky road looks delicious, I love all of the bright colours
Thank you Kat. This is definitely a Halloween RR! x
Brilliant! Im so so tempted to make this. I have two boys who love chilli but we could see how far their love of chilli goes. Now I have a wicked twinkle in my eye too. Thanks for linking up to #CookBlogShare
Ha ha! Yes….. It may just have them reaching for the water! x
Oooo I love this! I love chilli and chocolate so this would be for me. Such a funny idea!
Thanks Vicki! It went down well and I will definitely use again with other options inside! x
Oh so sneaky but I love it! I wouldn't like to be a recipient of the chilli bite though lol Perfect Rocky Road! x
Thanks Jo. The chilli recipients were good-natured when they found it, but I think were sort of expecting something as they were aware of the trick!
Ooh you're so mean Kate, I haven't seen that side to you before 🙂
I'm in two minds whether I'd want a slice, it looks so delicious, but that's a lot of chilli! (maybe I'll just make one without any 🙂 )
I'm not sure I like the idea of being mean Charlotte….. It is easy to temper the heat for the audience, though…. so I can feel less guilty! x
That rocky road looks spectacular but I am not into chilli so I would want to try other things – I saw an online video about making ping pong balls into eyeballs by drawing on them – this sort of thing could be fun to bury in there – not sure what else (tofu bacon???)
Thanks Johanna. I reckon you could squirrel just about anything in there, depending on your audience! It was fun to eat….. the anticipation definitely built with each 'normal' slice! x
This is a really creative Halloween idea, my kids love chilli chocolate and would be super happy if they actually picked it! Thank you for bringing your recipe to FF:) Pinned!
Ha ha! Thanks Monika. There are so many variables for this….. x
Wonderful idea Kate, this would go down a storm in our house infact this could be done all year round. My family and my sister in particular will love this at Christmas Video Night! (yes, we call it video night, just shows how long its been going on!)
Thanks Rebecca. It's funny…. I hadn't reflected on the flexibility of this idea as a party game…. there are so many adaptations though!
And yes….. Video is (sadly) a term that still escapes my lips to strange looks… I actually remember the days before video (aaagghh!) x
Great idea especially the chilli (or super sour sweet bit).
Thanks DC. It was fun! x
I think this is a fantastic idea, especially for adults! I think my kids would want to try it though. At least until one of them actually picked the chilli chocolate piece!
Thanks Corina. Miss GF was really keen on the trick, but then became more cautious as we ate through and the odds of getting the chilli increased! You can make it less strong though! x
