To start off, set your ice cream out on the counter and remove the lid, to let it start softening while you prepare the other ingredients.

Then, you will need to remove all the creams from your Oreos cookies. I set out a small bowl, and just used a butter knife to slide the creams off. Then put the cookie pieces in a separate larger bowl.

Next, use a large wooden spoon, or a potato masher, and crush the cookies. Don't crush them too finely, because you still want that crunchy cookie texture.

Microwave the jar of hot fudge without the lid for a minute. Stir it, then microwave for another 20 seconds.

Dump the jar into the crushed cookies. Don't scrape the jar clean, you'll need it for drizzle later.

Mix the cookies and hot fudge together until all the cookies are coated.

Dump the mixture into a 9" springform pan. Press it down in the bottom of the pan, to form a solid "crust."

Place it in the freezer for 15 minutes to allow it to set.

Remove it from the freezer. Use a silicone spatula to spread the ice cream over the top of the cookie crust. Leave a little room on the edges without ice cream, so it looks like the Dairy Queen version.

Sprinkle the miniature Reese's on top of the ice cream. Drizzle the remaining hot fudge on top of the entire Treatzza.

Cover with saran wrap and place flat in the freezer for 4-6 hours, or overnight for best results.

Cut and serve frozen.
