Chocolate Toffee Oaty Slice

You may or may not recall that the theme for January's Sugar High Friday event was cooking with candy. I got all excited because I had the perfect recipe. I couldn't wait to make it and post it. So I raced out and bought a stash of these.



And then stuff happened. So they sat on the kitchen bench for a while. Then stuff happened, and they got relegated to the cupboard. And then gradually they got shoved to the very back behind the sauce bottles and old dregs of vinegar. It's a bit of a metaphhor for life really.

So anyway, I stumbled across these good intentions again last week and decided the time had finally come. This is the end result - chocolate toffee oaty slice.


Unless someone told you, you probably wouldn't know that there are mars bars in there. The filling is deeply chocolately with a lovely mouthcoating gooeyness. There's an undercurrent of nougaty, caramelly, toffeeness. The oaty base and topping provide a lovely biscuity contrast. In other words, it's just really good.

I took it into work and it disappeared in short order. It always has, from the dozens of times I've made it.


I found this recipe on the BBC food chat board. It was posted by a very generous regular Sue L. I'm sure she she won't mind me posting it here. It's freely available on the BBC site.

Chocolate Toffee Oaty Slice
(adapted from BBC Food Board)

Line a 9x13 inch baking tin with paper.

225gm plain flour
110gm of oats
150gm light brown sugar
1/2 tspn 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 the tin.

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.

Place on a baking tray and bake for 25 minutes in a 180C oven until golden. Allow to cool for two hours before cutting.
