Oaty Chocolate Toffee Slice

A really good friend of mine, and all-round brilliant person, Mike, did something unimaginable a few weeks ago… he finished his PhD early. Not just a research PhD, mind you, a clinical one (for those who don’t see what all the fuss is about, just know it is superhuman to finish on time, let alone early). I am a loooong way off from submitting my thesis, but I look forward to the day with desperation (Soy does too, I can assure you). So I wanted to celebrate Mike’s massive achievement by…. baking him something, of course. He said he liked “chocolatey biscuity things” and so I set out to do some research, and found this Oaty Chocolate Toffee slice! I’ve never really been a big fan of slices, and I haven’t made them much, so I was looking forward to experimenting with something different.

The secret ingredient in these slices are… Mars Bars! So, almost all of the slice recipes I found called for copious amounts of condensed milk- a whole can! I couldn’t really bring myself to use a whole can of condensed milk to make the caramel, so I decided on this recipe because 1) no condensed milk and 2) I get to melt Mars bars! But, Soy, being a party pooper, pointedly remarked that if I thought that four Mars bars contained less sugar/naughty stuff than a can of condensed milk, I was sorely misguided. Ok, good point, but I was still stuck on the fact that I was going to melt Mars bars!

Move over, deep fried Mars bars!! I must say that we don’t eat Mars bars as is. I find them waaay too sweet. These emitted the most heavenly smells as they were melted into…. eep…. double cream.

Slices are fun to make, I think, because each layer is something different, which means you make something different as well.. unlike say, making one homogenous cake batter. And the slice turned out pretty good! I gave Mike a box of them, and kept a little for the household, which I cut up into minute little pieces cos they were a bit toothache-inducing! But the layers came together beautifully- the crunchy yet chewy oat base, bittersweet dark chocolate, sweet chewy caramel, and then more fragrant oaty bits on the top! Try this- I think they will be a hit at picnics, potlucks or in kids’ lunchboxes (in very small squares).

So tell me, what is your favourite chocolate bar?

Oaty Chocolate Toffee Slice

From the BBC Food Messageboard, originally published in Sainsbury’s magazine, Aug 1996.

225gm plain flour
110gm of oats
150gm light brown sugar
1/2 tsp bicarbonate soda
150gm of butter
1 egg, beaten

Blitz flour, oats, sugar and bicarbonate soda in a food processor for a few seconds. Add cubed butter and process until the mixture resembles breadcrumbs. Add the egg and process until the mix sticks together.

Press 3/4 of the mix into the base of a 9 x 13 inch baking tin lined with baking paper.

225gm dark chocolate

Melt the chocolate and pour over the dough base, leaving a small margin around the edges. Refrigerate until the chocolate has hardened.

150ml double cream
4 chopped up Mars bars

Bring cream to the boil and lower heat to a simmer. Add the Mars bars and stir until melted. Whisk until the mix is creamy. Pour over the hardened chocolate and dough.

Crumble the remainder of the oat mix over the top.

    Manjari Valrhona. Expensive but it gives you an excuse to not eat too much at one go.

    Oooh, I’ve only ever used Mars Bars in a rice-bubble mars bar slice (and heard of it used in cheesecake) so this is a brand new idea entirely!

    Favourite candy bar? Well, if we’re talking mass-market, Reese’s Peanut Butter cups. Artisan candy is a whole ‘nother story ;)
