In honor of the imminent end of summer, Dunkin' Donuts is offering some cold weather comfort to summer-lovers with a pair of brand new fall-flavored treats.

For a limited time, donut fans will be able to indulge on Pumpkin Cheesecake and Reese's Peanut Butter-flavored treats to their hearts' delight, thanks to the chain.

Though the delectable treats themselves won't be available in stores until August 31, FEMAIL was lucky enough to sample a bite - or ten - to find out whether they’re as delicious as they sounds – and whether they’re worthy of the rather high calorie count!

Festive flavors: Dunkin' Donuts gave FEMAIL a taste of their upcoming Reese's Peanut Butter Cup and pumpkin cheesecake flavored donuts, available from August 31

First up is the peanut butter and chocolate square, which is topped with chocolate glaze and an orange icing drizzle to match the colors of famous Reese's Peanut Butter Cups' branding. According to the Dunkin Donuts website, the tasty treat contains 340 calories and 400mg of sodium, meaning it isn’t the healthiest of breakfast options.

And, as the popular peanut butter cups will be flying off the shelves come Halloween, they make for a match in both color and contents for the fall theme.

It's the first time the popular donut shop has hooked up with The Hershey Company to produce an official donut, and, according to many of our tasters, the pairing was a huge success.

Assistant News Editor Michelle Curran said: 'I don’t actually like Reese's chocolates but I really liked the donuts. It tasted more like custard.'

Femail reporter Carly Stern thought the filling lived up to the well-known brand with aplomb, saying it 'had that smooth, extra-sweet peanut butter taste. It was really good!'

Reporter James Gordon agreed, adding that he 'enjoyed the mixture of salty and sweet as the peanut butter center began to ooze out'.

A big hit: Tasters were a big fan of the peanut butter and chocolate combo donut, with several praising it for staying true to the brand

But not everyone was as convinced by the combo.

'I got the peanut butter, and I was definitely nervous that it would completely overpower the donut. In the end I actually think it could have been a bit more peanut buttery,' said video editor Lindsay Meeks. 'The cream in the middle was more just whipped cream and sugar with a hint of peanut butter.'

Her thoughts were echoed by Femail Editor Charlie Lankston, who said that, while the 'chocolate and peanut butter option was delicious' she thought it 'could have done with a tad more peanut butter in terms of the flavor'.

The Pumpkin Cheesecake variety - which is filled with a pumpkin cheesecake cream and topped with orange icing, crumbled graham cracker topping and a white icing drizzle - proved even more divisive among the office tasters.

News reporter Kieran Corcoran fell on the thumbs-up side of the divide on the treat, which contains an impressive 340 calories and 400g of sodium, musing that the confection brought 'an autumnal rush a few weeks early.'

‘The square is soft and gooey, with plenty of filling,' he added. 'Its vivid orange icing makes for a colorful treat, although the crumbled graham crackers on top didn’t register much crunch.'

The great divide: The pumpkin cheesecake donut proved not as popular as the Reese's version - with several tasters criticizing the extreme richness of the filling

Sadly, things were not as satisfying for Charlie - who thought it was 'a bit too rich and creamy' - and picture editor Blanca Torres

'I absolutely love pumpkin pie, I also love cheesecake. Putting these together I thought it was going to be amazing,' said Blanca. 'I appreciate Dunkins’ attempt to make a new festive donut, but I think this donut is really far off. I wish the center would have been a bit more thicker and pumkin-ish. It was extremely sweet, nothing like pumpkin pie or a cheesecake.'

Femail reporter Valerie Siebert was similarly unimpressed by the effort.

'It was too rich and too sweet for me, and, to be honest, I couldn't really discern the pumpkin flavor very much,' she said. 'To be fair though, I'm not much of a cheesecake fan and some of the extra filling just ended up in the trash.'

As with any product from Dunkin' Donuts, if you don't have an intense sweet tooth, it may be best to steer clear.
