I'll try most new sandwiches at Dunkin' Donuts - they're usually appealing to me. The donuts, though? Not all of them.

I don't have the biggest sweet tooth, so something like strawberry frosting just doesn't do it for me.

But brownie batter filling? Yes please.

I saw the Brownie Batter Donut for the first time last week, on a stop-at-Dunkin'-on-the-way-to-school Dunkin' Donuts appearance with my daughter.

I try to set a good example on these (rare) mid-week Dunkin' stops. I try to convince her a bagel is a better option before school than a chocolatey donut, and I model for her by getting a bagel myself.

But when I saw that there was such a thing as a Brownie Batter Donut, believe me when I tell you that it took every ounce of self-restraint not just to settle on a bagel that morning, but to not sell Dunkin' Donuts my first-born right then and there for lifetime access to these donuts. (OK, don't believe me. It's not really true.)

I just love brownie batter. The literal brownie batter, in the bowl after you put the brownies in the oven? I'll lick that bowl clean. Any variation of fudge brownie ice cream? I'm all over it - it's a somewhat rare offering around here but I know the ice cream shops that carry it. And now a brownie batter donut - and it tastes as good as you'd expect.

It's like a chocolate frosted on the outside, and then in the middle (though not enough for me) there's brownie batter filling.

I'm sure it's so unhealthy. But I don't care. It's so good.

As you can tell by the picture above, it's shaped like a heart. Part of me dreads that's because it's a limited-time offering only through Valentine's Day, meaning there's only a couple of weeks to enjoy this delicious donut.

But the part of me that cares about my health is grateful that at least I know I'll have to stop eating them when they take them off the shelves somewhere around February 14th.
