REVIEW: Sinister Labs’ SINFIT Protein Cookies (Chocolate Chip, Birthday Cake, Peanut Butter)

Sinister Labs dubs themselves the “first hardcore food company”, fusing psychobilly art with high protein products packed with great taste. They burst onto the scene in 2017 with an impressive line of SINFIT Protein Crunch bars and this year have rolled out a new line of the hottest fitness foodie trend – protein cookies. On the surface these cookies present the most impressive calorie and macro split I’ve ever seen – 310 calories, 12g fat, 35g carbohydrates, and 20g of protein with just 7g of sugar and 400mg of sodium. While still higher than your average protein bar, if these cookies taste anything close to delicious they could easily be the strongest in the game – but really, how do they taste?


Chocolate Chip


First off, I don’t know in what bizarre-o Twilight universe a chocolate chip cookie looks like this, but it is menacing and dark as hell. Completely coated in chocolate and studded with chocolate chips, this is definitely more of a chocolate chocolate chip or even a brownie, than it is a traditional choco chip. No matter what you want to call it, this thing is wonderful. It has an authentic semisweet chocolate flavor, definitely heightened by the ample chips on top that crumble everywhere as I eat it, and a soft chewy texture, that once again, is more like a brownie than a cookie.


The inside is a little bit grainy like a lot of protein products, but compared to others it’s very minimal and it doesn’t take away from my enjoyment at all. The chips add a good crunch which brings depth to the chewy insides and it really tastes and feels way more like a treat than a supplement. I really like this cookie, and it’s by far the best protein cookie I’ve had, but it’s just short of perfect because it doesn’t give me any of the golden brown sugar shine I want when craving one of grandma’s classics. It’s more of a decadent chocolate coated brownie, and for the macros it’s an absolute success.

Birthday Cake


Aesthetically this one wins immediately – with loud colorful sprinkles and a pink drizzle that instantly scream party. The inside is soft and chewy with a little bit of a protein-y texture but no undesirable flavor or artificial presence at all. A softly sweet vanilla is the dominant taste with a bit of sprinkle crunch from the multi-colored explosion on top and baked inside.


The finish is a little bit on the dry side with a touch of graininess but it definitely reminds me of cake, or at the very least a frosted sugar cookie, which might be even more fitting. For this to be an absolute home run I would want it to be just a bit sweeter, as it almost comes across as too tame for birthday splendor, but it does get the job done, and I would absolutely chomp it again.

Peanut Butter


Peanut butter flavored protein products and I don’t have a terrific track record. While PB is without a doubt one of my favorite foods ever, my taste buds don’t like to be fooled and there really is no replacement for the real thing. Out of the bag this cookie once again looks awesome – garnished with chopped peanuts and a nice creamy brown coating that carries an authentic nutty aroma. Much like the other two SINFIT cookies this one has a great soft and chewy texture that’s top of its class not only for a protein cookie but for packaged soft cookies in general, which I feel oftentimes miss the mark. It’s also probably the closest to the texture of a good non-gains-infused PB cookie, which is usually pretty chewy and a touch dense from the butter. The base of the cookie has little peanut butter chips inside that add an extra touch of meltiness and sweetness that make for a truer PB representation than most.


This is the one of the best PB protein cookies I’ve ever had, but it’s still my least favorite of the bunch. The experience is lessened by how incredibly strong the SINFIT Peanut Butter Crunch Bar is, and this tastes like a less sweet less creamy version of that bar. It’s still a really solid effort and I recommend it to anyone who likes this kind of snack, but with more carbs and less protein than the bar I can’t see myself choosing this over the company’s other superior product.

Rating: 8.5/10

These cookies aren’t cheap, and at least for me aren’t available in any stores, but as I’ve said before, you do get what you pay for. The only way to pick up these bad boys is through their website or another online distributor like Campus Protein. It’s definitely a bit pricier than your average $1.99 Lenny & Larry’s, but the product is so much better that it warrants the heftier price tag and hopefully a big dawg like GNC gets smart and starts to carry them soon.
