Add in your crushed vanilla wafers into a bowl and add melted butter and brown sugar. Mix until it is a wet sand-like texture.
Place a circle parchment paper liner into the bottom of your cheesecake pan. Then lightly spray with a cooking spray.
Press down the cookie crumbs to make sure it is packed well on bottom and sides of the pan. Place the crust in the freezer as you prep the rest of the cheesecake.
Now for the raspberry peach cheesecake filling you want to beat your softened cream cheese until light and fluffy.
Add in the vanilla and sugar, and mix until creamy, then toss in the sour cream. Mix until blended.
Now you will add in your eggs one at a time, mixing until combined. Do not overmix at this point. Slowly add in your flour.
Now grab a bowl and split the cheesecake batter in two. This will be how you flavor one peach and flavor the other raspberry.
In a new bowl mash up 1 cup of your raspberries to make a puree and add in 1/4 cup sugar. Then you will do 1 cup peaches and 1/4 cup sugar for the other bowl of cheesecake. Mix the fruit fillings with the separated cheesecake batter.
Fold the cheesecake flavors into each one of the bowls. Add food coloring if you want to brighten the color.
Now pour 1/2 of one flavor of the filling in the Instant Pot pan, and then pour on the other filling. Use a toothpick or knife to swirl the cheesecake batter. Repeat the pouring a little of each to try and spread out the flavoring.
Cover tightly with aluminum foil. Then add 1 1/2 cups of water in the Instant Pot. Place your cheesecake pan on a trivet or silicone sling. Cook on high pressure for 50 minutes, followed by 10 minute natural release.
Once the cheesecake is done, remove and let cool on the counter for an hour.
Then refrigerate the cheesecake overnight or 6 hours. Once the cheesecake is fully set up then you can do the cream cheese frosting.
For the frosting add all your ingredients in the mixer, and whip until creamy. Then pour on top of the chilled cheesecake.
Top with remaining fresh berries and peach slices. The store your cheesecake in the fridge until you are ready to serve.
