I ate my way through the classic menu at Insomnia, the cookie chain that dominated the market long before Crumbl's debut

I'm a fan of M&M's, so I was surprised by how much I disliked Insomnia's classic cookie featuring the candy.

There was no dimension here — it was just a plain cookie and M&M's mixed together.

Although it would certainly scratch an itch if you had a sweet tooth in the middle of the night, I thought the flavor ultimately fell flat compared to the rest of the cookies.

I'm normally a fan of peanut-butter cookies, so I felt especially let down by this flavor.

The ratio between peanut-butter chunks and cookie looked balanced. But upon tasting, the nutty flavor was overwhelming.

It tasted like eating a spoonful of peanut butter, and although that's not necessarily a bad thing, it's not what I look for in a cookie.

The chocolate-chip cookie market is competitive and oversaturated these days. Insomnia's offering just didn't stand out from the crowd.

After a few bites, the flavors and textures of the cookie and chocolate were nearly indistinguishable.

It's not something I'd specifically seek out again, but I'd eat it if it were placed in front of me.

I'm quite vocal about my distaste for raisins, but I actually liked Insomnia's oatmeal-raisin cookie.

It had a tasty balance of sweetness with notes of cinnamon and molasses.

My only complaint was that there were far too many raisins, which ruined the texture for me. But if you're a fan of the dried fruit, that probably wouldn't be a problem for you.

The cookie had a mix of white-chocolate chips and macadamia nuts — flavors I find so distinct that I almost had a hard time comparing it to the others.

It was definitely on the sweeter side, and I know not everyone enjoys white chocolate. But if I could only choose one Insomnia cookie to satiate a serious sugar craving, this would be my pick.

Throughout college, my go-to order at Insomnia was a warm Snickerdoodle cookie. The buttery base topped with cinnamon sugar was consistently good and fit pretty much any occasion.

But compared to the other cookies, this reliable flavor surprisingly faltered due to its lackluster flavor.

Insomnia's double-chocolate-mint cookie offers a dark-chocolate base with mint chips and pieces of milk chocolate throughout.

Although mint-flavored desserts are a little controversial — it's certainly a strong flavor that you either like or don't. I loved its almost Christmas-y flavor profile.

Texture-wise, it was a bit harder than the other cookies, but the flavorful mint chips made up for it.

Although the double-chocolate-chunk and double-chocolate-mint cookies were very similar, the plain chocolate version surprised me more.

With its mix of milk and dark chocolate, it had an enticing balance of sweet and bitter flavors.

All the chocolate, surprisingly, wasn't overbearing — I'd even say it was fairly light for a chocolate cookie.

Insomnia's buttery sugar cookie with hints of vanilla snagged first place. Its soft texture and subtle flavor were nearly perfect.

A sugar cookie is kind of an old reliable. If you're overwhelmed by the number of flavors to choose from at Insomnia, this is my suggestion for a dependable sweet treat.
