The combination of brown butter flavor and chocolate chunks is perfection. I'm not surprised that fans are going wild on social media about them. Costco's really hitting it out of the park with their bakery offerings these days. Can't wait to see what else they come up with next!
peanut butter lovers in the win! i'm all for trying new treats, especially when they're from a reputable store like costco. those brown butter-flavored dough and medley of ingredients sound AMAZING 
. i do wonder if they'll be on sale during holiday season tho 
. also, 4.5 million pies sold in 3 days is wild 
! what's your fave costco bakery treat so far? 
. First, Costco introduces these Peanut Butter Monster Cookies, and suddenly all the peanut butter fans on social media are going wild? It's just too convenient 
. And what's up with the "Peanut butter lovers, this one's for you" statement? Sounds like some kind of marketing ploy to me 
. I mean, can't they just make it seem like a random addition to their bakery lineup without all the fuss? It's probably gonna be some secret way to gather data on customer preferences or something 
... and I'm not buying it 
.
anyway, i'm so down for these peanut butter monstrosities. i mean, who doesn't love a good cookie overload? it's just another example of how far we've come as consumers with the rise of online shopping and big box stores... but hey, more options is always better, right? 
they sound soooo good with brown butter-flavored dough and all those peanut butter candies 
and tbh who needs a diet when there are treats like this available at costco 
i mean, 4.5 million pies sold in q1 2026? that's some serious holiday sales figs 
can't wait to get my hands on those cookies! 
?! i think this is such an awesome move by costco! who doesn't love peanut butter, right? they must know that their members (aka us!) are crazy about it. and the fact that they're offering a mix of ingredients like peanut butter candies, chips, oats, and chocolate chunks is genius - its like a party in your mouth 
. Like, I get it, peanut butter is a solid flavor, but monster cookies? It sounds like something my little cousin would make for me when I was 10. And don't even get me started on the Instagram post - "Peanut butter lovers, this one's for you"? More like "Peanut butter enthusiasts, this cookie's gonna cost you". Mark my words, these cookies are gonna be overpriced and overhyped. The whole thing just feels like a marketing gimmick to get people to buy more stuff at Costco 
.
People get so hyped about trying new foods, but let's not forget that too much of a good thing can be, well, too much 
. These Monster Cookies sound amazing, but if you're gonna indulge in them, make sure to balance it out with some healthy habits. Remember, life is all about finding that sweet spot (pun intended) 
Can't wait to try them out and see what all the fuss is about 
And the fact that they're part of Costco's bakery lineup means we'll be able to get them at an awesome price. I love how excited all these peanut butter fans are on social media - it just shows how much people LOVE trying new treats!
