Doughnuts are like pizza — even when they're bad they're good. So why not combine them?

According to Bostoneater.com, two Beantown doughnut shops had the same idea. The website says two of the area's popular doughnut shops recently introduced their own versions of pizza doughnuts. At Union Square Donuts, the team has added Cheese Pizza Savory Donut Squares ($3.50) to its collection of square-shaped, non-dessert doughnuts. The shop's doughnut dough is baked instead of fried with fresh basil, fresh garlic, mozzarella cheese and tomato.

Meanwhile, across the river, Blackbird Doughnuts, a new South End shop from The Gallows team, is currently offering a pepperoni pizza doughnut for $3.
