Mudslide Cheesecake

This cheesecake is made with ingredients found in most cheesecakes with the addition of Irish Cream and Vodka. Cream cheese and sour cream pair up in this cheesecake to make it smooth and creamy, making this a great cocktail-inspired dessert.

Cheesecake 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 to make the crust and place it 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.

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.

For this particular recipe, 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 into the cheesecake mixture.

I prefer to use a food processor to make my cheesecakes because you can use small pulses to combine the ingredients.

The cream cheese is blended to a smooth creamy consistency and the granulated sugar is added into the cream cheese. Once those ingredients are blended together, the Irish cream, vodka, vanilla extract, and sour cream are blended in.

Once those ingredients are combined, the melted dark chocolate is added in as well as the cornstarch. Cornstarch helps prevent cheesecakes from cracking and helps firm up the cheesecake.

The cornstarch is a great help in this recipe because it has quite a bit of liquid to help firm this Instant Pot Mudslide Cheesecake up.

Lastly, the eggs are added one 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.

Placing the Instant Pot Mudslide Cheesecake 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.

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.

Different Size Cheesecakes and Chessecake 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 amount 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.

  2. Lower the sling into the Instant Pot.
  3. Set the Instant Pot to MANUAL/PRESSURE COOK for 46 minutes.
  4. Allow the pot to completely naturally release (about 18 minutes) Naturally release means to leave the pot sit after the timer is up. The pressure will release on its own. The pin will drop once the pressure is released.
  5. Carefully remove the cheesecake from the Instant Pot and remove the foil.
  6. Use a paper towel to dab any condensation that has collected on the cheesecake.
  7. Allow the cheesecake to sit on the counter for 10 minutes before transferring it to the cheesecake to chill in the refrigerator for at least 24 hours.
  8. Once the cheesecake is filled, remove it from the pan, serve as is, or garnish it with topping.

Irish Cream Whipped Cream

  1. If using the unflavored gelatin to stabilize the whipped cream: Heat 2 tbsp of water until hot and add the 1/2 tsp of unflavored gelatin and allow it to dissolve.

  3. Once peaks begin to form add the Irish Cream and beat until peaks begin to form.
  4. At this point, add in the cooled gelatin mixture and beat until combined.
  5. Pipe as desired on cheesecake.


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.
