Quick dessert using up bunch broken chocolate chip cookies?

Biscotti is what I was hoping to do I had a whole container of cookies that are hard as rocks and crumbled half of it but I think I might do the parfait as well as the pie.

If its for one person, I would put the broken bits in a bowl, pour milk over and eat with a spoon! All. By. Myself.

You could make Ina Garten's Mocha Chocolate Icebox Cake. It's kind of like a tiramisu, but using chocolate chip cookies instead of ladyfingers. Of course, Ina uses unbroken cookies in layers; but since the cookies are transformed into cake by cream and mascarpone, by serving time,
no one will know that your cookies are broken.

I have done it with a chocolate/vanilla marbled cheesecake and it added another dimension. Crunch and additional chocolate can’t be beat. Actually like it more than a graham cracker crust.

Instead of a graham cracker crust for your cheesecake, use finely crumbled chocolate cookies.

I'm a little late to the game, but I would recommend mixing broken cookies into ice cream (aka cookies & cream). My favorite Ben & Jerry's flavor, Cookies & Milk, does this with choc chip cookies and brownie bits. Soften ice cream, mix in cookies, and refreeze.

Why not just eat them? Most people who bake eat a lot of broken cookies.

Make cookie Crumb pie crust (one large or individuals), then serve with filling of your choice.

Building on everyone else's great brainstorm here with layered parfaits...if you're hosting, why not have a Parfait Bar? You can offer up flavours of ice cream, some whipped cream, a few fresh berries/fruits, pudding(s), and as a timesaver, Philadelphia cream cheese even offers a cheesecake filling in a tub. (Now I wish *I* had some broken cookies to use up!)

Individual desserts.... start with a fancy wine glass. Add cookie pieces, a layer of whipped topping (or vanilla pudding), sliced bananas, more cookies, a layer of whipped topping and a drizzle of chocolate syrup. Top with a fresh berry.😋 BB

Why not do a parfait? layers of pudding or whipped cream in a tall parfait glass separated by a thin layer of your cookies? You could even layer some fruit in there or a tiny bit of preserves.

I'm pretty lazy so I'd probably just sprinkle them over ice cream, as a crunchy topping.

I suppose other easy uses would be as a substitution in tiramisù or a trifle for the standard lady finger cookies called for in both dishes. These would be non-standard adaptations but I would think they would taste okay.

Actually, I kind of like the idea of doing some sort of layered ice cream but that would require you to soften ice cream, mold it, add a layer of cookies, add more soft ice cream, etc., freeze until solid and serve. That's too much work for me but it might work for others.

Anyhow, I have no specific recipes to point you do. These were just a few ideas off the top of my head.

Best of luck.
