I compared the same breakfast from Dunkin' and Krispy Kreme and they were surprisingly different

The most conveniently located Krispy Kreme was a 20-minute subway ride away in the Flatiron District. I was a little nervous about having to travel far out of fear that the doughnuts would be in rough shape by the time I got back. They melted a little but were still good to eat.

I hit up Dunkin' on the way back — it was located right off my closest subway stop in Williamsburg, Brooklyn.

My iced coffee from Krispy Kreme was a little watered down — it was 90 degrees out, after all — but other than that, both looked in good condition.

From Krispy Kreme, I got a chocolate iced doughnut with Kreme filling — the closest thing they had to a custard doughnut — and a glazed doughnut with raspberry filling. From Dunkin', I got a classic jelly doughnut and a Boston Kreme doughnut.

The doughnuts were very similar but varied slightly in their appearance and filling. I thought it would be interesting to see how Dunkin' and Krispy Kreme approached these two classic doughnuts in different ways.

From both chains, I ordered a medium iced coffee with cream and sugar. The iced coffee from Dunkin' cost $3.39 at my nearest location in Brooklyn, New York.

I thought the coffee was sweet and creamy but didn't have a strong coffee bean flavor. It tasted like cream with just a hint of coffee flavoring. However, I thought the medium was a generous size and could certainly power me through a hot day out and about in the city.

Both doughnuts were noticeably larger than the doughnuts from Krispy Kreme.

It was hardened and didn't appear to have melted at all despite being out in the sun for a short while. The doughnut cost me $1.69.

The custard was creamy and thick, but there could have been more piped into the doughnut so that each and every bite contained some of it. The doughnut was slightly cakey in texture as well, instead of being light and fluffy.

The doughnut cost me $1.69. Right away, I noticed the hole where the jelly is piped into the doughnut.

I thought the doughnut had a generous amount of filling and had a better doughnut-to-filling ratio than the Boston Kreme.

A medium iced coffee with cream and sugar cost $2.99 at my closest Krispy Kreme in Manhattan, New York. It was on the smaller side, and I thought I had been handed a small size at first. However, my receipt said I received a medium.

It tasted like real coffee, unlike the one from Dunkin'. It had a slightly more bitter flavor and was less creamy. In the end, it's totally up to personal preference, but I preferred this iced coffee.

Despite looking a little worse-for-wear after the trip back home, the doughnuts still smelled delicious.

The chocolate iced doughnut with Kreme filling cost me $2.09. It was smaller than the Dunkin' one and had a thinner layer of chocolate icing. However, it also looked less artificial, in my opinion.

Krispy Kreme also sells custard-filled doughnuts but didn't have any at the location I visited. However, both concepts are still extremely similar. The cream inside was light and fluffy, almost like marshmallow.

There was a delightful amount of filling — every bite contained some of the cream. The doughnut itself was also light and fluffy, which allowed the filling to shine through. However, the chocolate icing ended up fading into the background for me. It could have used a little bit of a thicker icing.

Krispy Kreme's glazed doughnut with raspberry filling also came to $2.09.

It was gooey, tart, and delicious.

To me, this is the mark of a perfect jelly doughnut.

However, I thought the iced coffee from Dunkin' was better bang for your buck.

The glaze added the perfect amount of sweetness, and there was an abundant amount of tart, delicious jelly filling.

The doughnut from Dunkin' had a thicker layer of icing but less filling.

In the end, I liked both but had to give the win to Krispy Kreme for flavor. It was a relatively inexpensive breakfast with delicious, homemade-tasting doughnuts.

However, I thought Dunkin' was better value. For 40 cents less, I got more food and coffee than I did at Krispy Kreme.
