Ever notice how your mood instantly lifts after a really good cookie? Like your shoulders drop, your stress quiets down, and for a second everything feels… fine?
That’s not just in your head. There’s actual science behind it.
When you eat something you genuinely enjoy, your brain releases serotonin; one of the main “feel-good” chemicals responsible for mood, calm, and overall happiness. Comfort foods are especially good at triggering this response, and cookies? They’re basically serotonin’s favorite snack.
Carbs help your body absorb tryptophan (an amino acid your brain uses to make serotonin), sugar gives you that quick mood boost, and the simple joy of eating something nostalgic and indulgent lights up your brain’s pleasure pathways. Add real chocolate into the mix and you’re stacking the odds in your favor.
This is where Just A Cookie Co.’s OG Chocolate Chunk comes in.
It’s our take on the best version of a classic chocolate chip cookie: thick, soft-centered, loaded with melty chocolate chunks, and baked to hit that perfect balance between nostalgic and next-level. It’s the kind of cookie you slow down for. And that matters, because enjoyment amplifies serotonin. The more you savor it, the more your brain leans into that feel-good response.
There’s also something deeply comforting about a cookie that’s done right. It reminds you to pause. To treat yourself without guilt. To enjoy a small moment of happiness in the middle of a busy day. Your brain recognizes that comfort...and rewards you for it.
Will a cookie solve everything? Probably not.
Will an OG Chocolate Chunk from Just A Cookie make your day noticeably better? Science says… very likely.
Consider it serotonin, but make it delicious. 🍪
