For the crust
1 Cup Oreo Cookie Crumbs about 12 cookies
2 Tablespoons Butter melted
For the Filling
12 ounces Softened Cream Cheese
1/2 Cup Sugar
1/2 Cup Smooth Peanut Butter
1/4 Cup Heavy Cream
1 1/2 Teaspoons Vanilla
1 Tablespoon Flour
2 Large Eggs at room temperature
1 Large Egg Yolk at room temperature
For the Ganache
6 ounces about 3/4 Cup Milk Chocolate, roughly chopped
1/3 Cup Heavy Cream
2/3 Cup Roughly Chopped Peanut Butter Cups
Spray a 7″ springform pan with nonstick spray.
Pour 1 cup water into the instant pot and place a trivet in the bottom.
To Make the Crust
In a bowl, stir together the cookie crumbs and butter.
Spread the crust evenly in the bottom and about 1″ up the sides of the springform.
Freeze for 10 minutes.
To Make the Filling
In a large bowl, with a handheld mixer, mix the cream cheese and sugar on medium speed until smooth.
Blend in the peanut butter, heavy cream, vanilla and flour.
One at a time, mix in the eggs and egg yolk.
Pour the batter over the crust and cover the pan with foil.
Make a sling by folding a long piece of foil lengthwise to make it strong. Place the cheesecake on the sling and gently lower onto the trivet.
Lock the lid and cook at high pressure for 50 minutes.
Turn off the pressure cook and do a natural release for 10 minutes and then a quick release.
Remove the lid and foil, and using an instant read thermometer in the center of the cheesecake, make sure the cheesecake has reached 150 degrees farenheit. If it hasn’t, place everything back on and cook an additional 5 minutes, 10 minute release and check the temperature again.
Remove to cool and remove the foil.
After it’s cooled, place in the fridge for 3-4 hours or overnight.
To Make the Ganache
Place the chocolate in a large bowl.
In a small pan over medium heat, bring the heavy cream to a boil.
Pour the hot cream over the chocolate and stir until smooth.
Pour over the cheesecake allowing to drip down the sides and sprinkle with peanut butter cups.
Refrigerate until ready to serve or enjoy
