On a mini weekend away in Castlemaine during July, I had the perfect piece of slice at
Stak's Cafe. It was a bit biscuity but more chewy caramel, with big chocolate buttons melted into the top and lots of roasted peanuts. It made me want to bake something similarly chaotic and sweet and salty, so I pulled out a recipe for '
quadruple crunch bars' from
Hungry & Frozen. It smashes together potato chips (
ever heard of 'em?), rice bubbles, butterscotch lollies and chocolate into a biscuit slice base.
I have to admit up front that I let down this recipe before it let down me. I melted the butter instead of creaming it with the sugar because I'm lazy about using electric beaters, this is a slice, and I wasn't convinced that it was needed. Then I used a medium-large bowl that was way too small for all the dough and the gentle folding needed here. From there I think the recipe needs to take some responsibility: there was way too much mixture for a 25cm square baking tray, perhaps even too much for the 25 cm x 30 cm tray I tried after that. There was so much chocolate (complimentary) that it wasn't to be drizzled about playfully, but instead thickly spread across the entire slice.
Honestly, this was not quite the crunch-a-thon I was hoping for (although the height of the slice certainly did have it crashing into the roof of my mouth). I was surprised how much the potato chips, rice bubbles and butterscotch melded into the biscuit dough. The slice did get a bit crunchier after storage in the fridge. I think these were originally intended to be cookies and I'm tempted to backtrack to that version... rolling the biscuit dough into loose balls and shoving chunks of the crunchy ingredients (choc chips included) into it. This was a sweet, fun slice and yet I hold out hope that there is an even more brilliant recipe lurking within it.
Some slice with some crunches
250g butter
300g brown sugar
2 teaspoons vanilla
1/2 teaspoon bicarbonate of soda
1/2 teaspoon baking powder
300g plain flour
2 tablespoons milk
150g plain salted, ruffled potato chips
60g rice bubbles
200g chocolate
Preheat an oven to 190°C. Line a walled baking tray with paper (at least 25 cm x 30 cm).
Melt the butter and place it in a very large bowl. Stir in the brown sugar, then the vanilla, then the bicarb soda and baking powder. Sift and stir in the flour and then the milk, mixing until well combined.
Crush the potato chips and add 3/4 of them to the bowl, along with the rice bubbles. No need to stir them just yet!
Unwrap and roughly chop the Werther's butterscotch lollies and add them to the bowl. Now it's time to carefully fold the crunchy things through the dough, mixing until just combined.
Transfer the mixture to the baking tray and use the back of a spoon to spread it out as evenly as you can. Cut slices into the dough where you plan to portion it later. Bake the slice for 25-30 minutes, until golden on top. Allow the slice to cool.
Melt the chocolate using your preferred method and spread it over the slice - the original recipe suggested decorative drizzling but I had plenty for a full layer across the slice. Sprinkle over the remaining chips so that they're caught in the chocolate as it sets. Cut and serve the slice after the chocolate has set.
