REVIEW: Trader Joe’s It’s Sedimentary, My Dear Cookie

Trader Joe's It's Sedimentary My Dear Cookie

On picking up Trader Joe’s It’s Sedimentary, My Dear Cookie mix, I couldn’t help but roll my eyes a little. The precious Mason jar, the muted tones of the “candy coated chocolate drops,” the cutesy crowd-sourced name. I wanted to trust the company that’s kept me in Speculoos Cookie Butter all this time, however. I read the instructions – mix butter and egg, dump entire jar in.

Wait. What?

First rule of Cookie Baking Club is: cream the butter and sugar first. Most cookie recipes (and all mothers) will tell you that whipping the sugar and butter together until pale and fluffy before everything else is cookie gospel. It’s what makes them light and airy. Now Trader Joe was telling me not to. I feared ending up with hockey pucks – something your childhood friends’ hippie parents would give you, saying “These are better than Chips Ahoy, trust me!”

Initial impression opening the jar was the smell of OATS! The oat force was strong with this one. Peanut Butter chips and graham cracker crumbs were present, although aromatically invisible. The dough came together quickly in my mixer – less than 30 seconds. Second rule of Cookie Baking Club: Don’t overmix!

Using a loosely-packed 2-Tbsp scoop, I was able to form 30 cookies, despite the label stating it would make 18. That’s a pretty good yield. Next – refrigerate the dough for two hours.

TWO HOURS? What kind of patience and willpower does Trader Joe’s think I have? With a tiny fridge, I had to cram every other cold item I own into the crisper bin so these free-range oat balls could chillax.

Eventually, it was time to bake. Since they were cold, the dough didn’t spread or flatten much – more like puffed out into domes.

I must admit, these cookies surprised me.

They’re dense, but not potential deadly weapons in a food fight. More than 4 might leave you feeling like there’s rocks in your belly, though. They were crumbly on the outside and soft on the inside.

After baking, the oats piped down and let the peanut butter chips and graham cracker crumbs dominate the flavor, which I appreciated.

I would have liked more “candy coated chocolate drops” for color, but overall, this was a pretty decent cookie mix. Could be a nice gift for busy parents, kids, or anyone who wants to upgrade from the “cut and bake” pre-made cookie dough.

  1. Was the sugar and butter mixed or the directions followed?

    I am a directions snob. I always assume the manufacturer of what I am making knows better.

    1. Directions followed exactly as printed. For the sake of evaluating a product, I’d always follow their steps to the letter. For myself I’m a little looser.

  2. I saw this at TJ’s but didn’t really look. After reading your review and seeing the results, I am more intrigued to try it. Mostly because of the unusual, semisweet mixins it has: coffee, Graham crackers, and peanut butter chips. Mm looks and sounds yummy

  3. We are trying to recreate this recipe at home, any chance you have the measurements for the ingredients?! The stores nearby are sold out. Thanks! 🙂

    1. Sorry, I don’t have the actual measurements, but it came in a Quart-sized Ball jar. I checked my photos, and it looks like the top of the chips level hit right at the 3 cups mark. The white/brown sugar level went right up to the neck of the jar. I think the coffee powder was mixed with the flour on the lowest level – which came up to about 1 – 1.5 cups. Hope that helps!

  4. I just worked out what’s in jar in ounces
    White Sugar 3.85
    Brown sugar 3.35
    M&ms 2.885
    Peanut butter chips 2.15
    Oats & coffee 2.645
    Graham cracker crumbs 2.135
    Flour 6.99


  5. I made 1 tablespoon sized cookies. They are like rocks. Flavor is great but, if you value your teeth, dunk only¡
