How to Blind Bake Crust

I prefer to blind bake my cheesecake crust because it makes for a firmer crust than not blind baking. If you don't care about the "crunch" in your cheesecake crust, you can opt for placing it in the freezer to chill before adding the cheesecake filling.

Blind baking simply means combining the crust ingredients and placing them in the springform pan and baking it in the oven without the cheesecake filling.

There's no extra time added to blind bake a crust as the ingredients for the cheesecake filling can be made while the crust is in the oven.

I cut a circle of parchment paper out and place it on the bottom of the cheesecake pan before adding the crust. This helps when removing the cheesecake from the pan once chilled. Once the cheesecake is separated from the pan, gently peel away the parchment paper.

How to Make Instant Pot Cheesecake

Making Instant Pot Mudslide Cheesecake is incredibly easy and the key to making a successful cheesecake is to use room temperature ingredients. This allows the ingredients to blend together without a lot of effort and it helps prevent overbeating the ingredients.

Start with room temperature ingredients- The first step to make this Instant Pot Mudslide Cheesecake or any cheesecake for that matter is to use set the ingredients out on the counter to come to room temperature.

Melt the chocolate- The dark chocolate will need to be melted using either the microwave method or using a double boiler. Remove the melted chocolate from the heat and allow it to cool before adding it to the cheesecake mixture.

I prefer to use a food processor to make my cheesecakes because you can use small pulses to combine the ingredients without overmixing.

Beat the ingredients together- The cream cheese is blended to a smooth creamy consistency and the granulated sugar is added to the cream cheese.

Once those ingredients are blended together, the Irish cream, vodka, vanilla extract, and sour cream are blended in.

Next, the melted dark chocolate is added in as well as the cornstarch. Cornstarch helps prevent cheesecakes from cracking and helps firm up the cheesecake.

Lastly, the eggs are added one at a time and using small pulses until just combined. If the eggs are beaten too much the cheesecake will have large puffy areas and will come out lumpy.

This is easy to prevent, especially when using room-temperature eggs.

I lightly grease the sides of the springform pan before I spoon the Instant Pot Mudslide Cheesecake filling into the pan.

I also gently tap the springform or push pan on the counter to release any air bubbles that may be trapped in the cheesecake before placing it in the Instant Pot.

This next step is not necessary but I prefer to add aluminum foil around the top of my cheesecake to keep as much condensation as I can from forming on top of my cheesecake.

A silicone sling comes in handy to lower the cheesecake into the Instant Pot and for ease of removal. If you don't have a silicone sling, you can easily make one out of aluminum foil.

Pressure cook the cheesecake- To pressure cook the cheesecake, add the water to the inner liner of the Instant Pot and lower the mudslide cheesecake fitted with the sling down into the inner liner. Close the lid and pressure cook for 46 minutes on HIGH PRESSURE using the MANUAL/PRESSURE COOK setting.

Naturally release pressure- Allow the Instant Pot undisturbed for 18 minutes before removing the lid and cheesecake from the inner liner.

Allow the Instant Pot Cheesecake to cool- Remove the aluminum foil from the top of the cheesecake and dab a paper towel to soak up any condensation that may be sitting on top of the cheesecake.

Allow the cheesecake to cool for 10 minutes before placing it in the refrigerator to chill for at least 24 hours.

Serve- Once the cheesecake has chilled for at least 24 hours, decorate, slice, and serve.

Homemade Whipped Cream

Whipped cream goes so well with this Instant Pot Mudslide Cheesecake recipe and what is better than regular whipped cream is the addition of Irish Cream in whipped cream.

To make homemade whipped cream, simply beat heavy cream in a chilled bowl along with granulated sugar. Once peaks begin to form in the whipped cream, it is time to add the flavoring of choice. Beat until stiff peaks form and transfer to a piping bag if desired.

If using whipped cream to pipe, it will fall unless it has gelatin added to it to stabilize the ingredients. One half of a teaspoon of unflavored gelatin dissolved in two tablespoons of hot water is enough to stabilize this whipped cream recipe. Just be sure to add the gelatin at the end of mixing the whipped cream ingredients and after the gelatin has cooled.

Can You Freeze Cheesecake?

Yes, you can! Pre-slice the cheesecake and wrap it tightly before placing it in the freezer.

TIP: Slice cheesecake immediately after removing it from the refrigerator for easy cutting. A knife heated in hot water and wiped clean before slicing makes cutting cold cheesecake easy.

Cheesecake can be frozen for up to 1 month for maximum freshness.

Different Size Cheesecakes and Cheesecake Pans

What if you have an 8 qt Instant Pot?  You can still make this cheesecake with the 7-inch pan or if you would prefer you can make this recipe in an 8-inch pan.  

The number of ingredients (for the 7″) will make a slightly shorter cheesecake but it will still taste the same. 

If you are making the cheesecake in the 8-inch pan, you will have to adjust the time by at least 5 minutes.

Overbeating the ingredients will create a lumpy cheesecake. The trick to a successful cheesecake is to not overbeat the ingredients but instead to combine until just blended.
