Here are a few cleaner, more natural rewrites of your caption:
Polished storytelling:
I made these for an after-school snack once, and now my kids ask for them every day. I honestly don’t know why I didn’t think of it sooner—so easy!
Short viral style:
Made these as an after-school snack once… now my kids want them every single day. So simple, I can’t believe I didn’t try this sooner.
More emotional/family tone:
I tried these as a quick after-school snack, and now they’ve become a daily request in my house. Simple, easy, and a total win.
If you want, I can also turn it into a full recipe post or make it more “Facebook viral hook” style.
