WHEN it comes to sweet spreads, shop shelves are choc-full.

The latest addition is a Mars bar in a jar.

And the chocolate and caramel-striped paste will be the next big thing, according to food mag Delish.

It reckons it’s perfect: “Stirred into porridge, slathered on toast or just eaten from the jar with a spoon.”

It joins the likes of Milky Way, Maltesers and Crunchie, which are all available in spreadable form.

Here Kate Jackson and her sons Dylan, eight, and Joe, six, give their taste verdicts and combined family score out of five.

And we see how many calories and grams of sugar they contain compared with the bars that inspired them . . .

MUM'S VERDICT

THE boys couldn’t believe their luck when they saw this sweet haul – and of course they kept retesting, “Just to make sure”.

Great on toast, but I reckon these bars in jars would be even better on pancakes, crumpets and waffles, and in cakes and milkshakes. There are so many possibilities.

I’ll definitely be trying them in my porridge, too – and then putting them under lock and key to save my waistline.
