This rich and decadent keto flourless chocolate cake is made using a pressure cooker (or a slow cooker) and is one of the most simple keto desserts to master.
Place the dark chocolate and butter in a microwave safe bowl and microwave on high for 90 seconds, stirring every 30 seconds. By this stage, the chocolate and butter should be melted. If not, heat for another 30 seconds.
Remove from the microwave and add the sweetener, stirring until well combined. Let it sit on the bench until cool to touch, about 4 to 5 minutes.
Stir in egg yolks until well combined. Whip the egg whites in a separate bowl until soft peaks form. Pour the chocolate mixture into the middle of the egg whites and gently fold until well combined.
Line a 7 inch (18 cm) cake tin with parchment paper and grease with the butter. Pour in the chocolate cake mixture and wrap with aluminum foil. Pour 1 cup of water into the pressure cooker and set the trivet into the pot. Place the cake on top of the trivet. Close the lid and make sure the air vent is in the sealing position.
Set to PRESSURE COOK/MANUAL for 35 minutes. Allow to natural release for 8 to 10 minutes before removing the cake. Allow to cool completely on a wire rack before removing it from the pan and serving.
The cake will keep in the fridge for up to 5 days or in the freezer for up to 2 months.

What is the release valve on my pressure cooker?On your pressure cooker, you will have a valve on top that has a small handle. You can either set this to sealing or venting.To cook under pressure, you will always need to set the valve to sealing.To release the pressure, you have two options, quick release or natural release.
Natural Release Function
The natural release function is when you allow the pressure to escape naturally without turning the valve on top. Once the pressure cooking function has finished, the pressure inside the pot will begin to drop naturally, slowly letting steam out of the valve. The pin will drop by itself, and you will be able to open the lid without releasing the valve on top.This is especially good for large cuts of meat, baked goods, or thick, soupy style recipes which might foam out the top of the pressure releases too quickly.During a natural release, the cooking continues so you need to take that into account when determining your cook time. If a recipe calls for a quick release, you can use a natural release if you prefer, but reduce the cooking time.
Do you need a trivet?
The reason why you need a trivet is simple; if you don’t want your food sitting in water (all desserts plus whole chickens), a trivet is necessary. There are a few different types of trivets you can purchase including ones with handles and ones without. I use the one without handles, but it can get a bit tricky to remove unbalanced items like creme brulee, so I suggest getting a trivet with handles. It should be made of food-grade stainless steel. Just be sure it fits your particular pressure cooker.
