Popping bonfire toffee cakes

Whoosh, pop, bang!  With bonfire night looming; make these (gently) explosive treats to keep you going, while you stand outside and wait for the fireworks to be lit.  Guaranteed make any firework party go with a…’pop’!!  This might not be the best recipe to cook with kids- as the toffee gets so hot- but they can help with the garnish and will enjoy eating it!

Preparation and cooking time: 20 minutes plus cooling (best made the day before serving).

Makes 8 generous triangles.


Greaseproof paper

80g toffee

60g marshmallows

20g butter

50g Cornflakes (Rice Krispies would probably work too)

2 packets (12g) of popping candy


  1. First you need to do a bit of prep, because once this mixture is fired up, you need to work fast- its very very hot, and very very sticky!  So: line a rectangular heatproof dish (around 14Cm x 20Cm is just right but bigger is fine) with a generous layer of greaseproof paper.  You need enough paper to go up around the edges and fold right over the top of the dish, as well as inside it.
  2. Put the (unwrapped!!) toffee, marshmallows and butter in a pan and slowly melt on a gentle heat, stirring occasionally.
  3. Remove the pan from the heat, add the cornflakes and mix well until all of the conflakes are pretty well coated- you will need to do this fairly gently (so that you don’t crush the cornflakes too much), but also fairly fast- this sticky concoction will start to get increasingly sticky and hard as it cools.
  4. Quickly turn the mixture out onto your greaseproof paper, and flatten.  You are aiming to make a fairly neat and flat slab, about 2 Cm thick.  I have found the best way to do this is by folding the greaseproof paper onto the top of the mixture and pressing it down (be careful with this though as the toffee is hot!!).  The toffee does not stick to the greaseproof paper but it clings to a spoon ‘like no tomorrow’.
  5. Leave your slab to cool, preferably overnight.
  6. Once cooled, put the slab onto a chopping board and cut into triangles (or whatever shape you fancy).
  7. Just before serving, garnish your triangles with a good helping of popping candy- the candy will start popping as soon as it is exposed to the air, so you need to add it right before you eat it, for maximum pop in the mouth.
