Instant Pot Oreo Cheesecake (No Wiggly Middle, No Cracks)

If your Instant Pot cheesecake keeps coming out jiggly in the middle even after a night in the fridge, the fix is almost always time, not technique. This Instant Pot Oreo Cheesecake needs the full 35 minutes on high pressure, a 10-minute natural release, and at least 6 hours in the fridge (overnight is better) before it’s actually set. Skip any one of those and the center stays loose. This version has an Oreo cookie crust, crushed Oreos folded right into the filling, and a crushed Oreo topping, all made in a 7-inch pan that fits neatly inside a 6-quart Instant Pot.

I’ve made this one more times than I can count for our little household of two, and it’s become the cheesecake I reach for whenever I want the real deal without turning on the oven for an hour. It’s rich, it’s decadent, and it disappears fast.

In the past, I’ve made a few different versions of Instant Pot cheesecake, including this really delicious New York style cheesecake, as well as this amazing pumpkin cheesecake. This one is basically a spin on the New York cheesecake with Oreos worked into every layer. It’s a special-occasion treat: super decadent, super rich, and worth every bite.

Why Is My Instant Pot Cheesecake Still Jiggly in the Middle?

A jiggly center almost always comes down to one of three things: the pressure time got cut short, the natural release was skipped, or the cheesecake didn’t chill long enough afterward.

The Instant Pot cooks this cheesecake gently with steam, so the eggs and cream cheese keep firming up even after the pot shuts off. That’s why the 10-minute natural release matters. Releasing the pressure immediately shocks the cheesecake with a sudden temperature drop, and it can leave the center underset or crack the top.

Chilling does the rest of the work. A cheesecake that looks slightly jiggly right out of the Instant Pot is normal. It should firm up as it cools, but it needs at least 6 hours in the fridge, and overnight is genuinely better, before you slice into it. If yours is still loose after a full overnight chill, double check that you used the full pressure and natural release times. Those two numbers matter more than anything else in this recipe.

What You’ll Need

The Pan Is the Part That Trips People Up

A standard 9-inch springform pan is too big for any Instant Pot. You need a 7-inch pan, which fits comfortably inside a 6-quart or 8-quart Instant Pot with room for the latch on the side.

This is the pan I have (that’s an affiliate link) and it works great in my 6 quart Instant Pot. A lot of readers swear by this Fat Daddio’s push pan instead (also a paid link) since there’s no seam for water to sneak in. Side note: whoever came up with the brand name Fat Daddio’s deserves a raise. That’s some funny, memorable stuff.

The good news: that pan isn’t a one-recipe purchase. I use mine constantly for mini lasagna in the Instant Pot too, and it’s the perfect size for a household of two.

Ingredients at a Glance

The full ingredient list and exact quantities are in the recipe card below. At a glance, you’re working with crushed Oreos and melted butter for the crust, cream cheese, sugar, eggs, vanilla, and sour cream for the filling, plus more crushed Oreos folded in and on top.

How to Make Instant Pot Oreo Cheesecake

1. Spray a 7-inch springform pan and line the bottom with parchment or foil. Mix crushed Oreos with melted butter and press firmly into the bottom of the pan.
2. Beat the softened cream cheese until smooth, then add sugar, eggs, vanilla, sour cream, and the chopped Oreos for the filling.
3. Pour the filling over the crust and smooth the top. Cover the pan with foil, crimping it tightly around the edges.
4. Pour 2 cups of water into the Instant Pot and set a trivet in the bottom. Use a foil sling to lower the pan onto the trivet.
5. Lock the lid, make sure the valve is set to sealed, and cook on high pressure for 35 minutes.
6. Let the pressure release naturally for 10 minutes, then release any remaining pressure manually.
7. Use the sling to lift the pan out, remove the foil, and let the cheesecake cool on the counter for about an hour.
8. Refrigerate for at least 6 hours, preferably overnight, before topping with more crushed Oreos and a drizzle of chocolate sauce and slicing.

How to Get a Fully Set, Crack-Free Cheesecake Every Time

• Don’t skip the foil tent. Sealing foil tightly over the pan keeps condensation from pooling on top of the cheesecake as it cooks, which is one of the most common causes of a soggy or cracked surface.
• Give it the full 10-minute natural release. This is the single biggest fix for a jiggly middle.
• Chill for real. Six hours is the floor, not the target. Overnight gives the filling time to fully set and makes cleaner slices.
• Skip the extra water bath. The Instant Pot’s steam already does the job a traditional oven water bath does, so you don’t need to add one on top of the 2 cups already in the pot.

Frequently Asked Questions

Why is the middle of my Instant Pot cheesecake still jiggly?

It usually means the pressure time, natural release, or chill time got shortened. Give it the full 35 minutes on high pressure, a full 10-minute natural release, and at least 6 hours in the fridge before checking again.

How long does Instant Pot Oreo Cheesecake need to chill?

At least 6 hours in the refrigerator, and overnight is better. The filling keeps firming up as it chills, so cutting into it early is the most common reason it looks underdone.

What size pan do I need for Instant Pot cheesecake?

A 7-inch springform or push pan. A standard 9-inch springform pan is too large to fit in any Instant Pot model.

Do I need a water bath in the Instant Pot?

No. The 2 cups of water already in the pot, combined with the sealed pressure environment, does what a water bath does in a regular oven.

Can I use double-stuff Oreos instead of regular?

Regular Oreos work best here. Double-stuff Oreos add extra filling that can make the crust greasy and throw off the texture of the batter.

Can I freeze Instant Pot Oreo Cheesecake?

Yes. Let it cool completely on the counter, then chill it in the fridge before wrapping tightly and freezing. Thaw overnight in the fridge before serving.
