Ingredients needed:

These are the basic ingredients for this instant pot chocolate cake recipe. Scroll down to our handy recipe card for detailed instructions and measurements. 

  • Butter: Unsalted high-fat butter, such as Plugra.
  • Chocolate chips: We used semisweet chocolate chips.
  • Dutch process cocoa powder
  • Fine sea salt
  • Sugar: Granulated white sugar.
  • Light brown sugar
  • Strong coffee: Instant coffee is fine.
  • Vanilla: Pure vanilla extract.
  • Eggs: Large eggs at room temperature.
  • Toppings: Whipped cream and berries.

How to make instant pot flourless chocolate cake recipe?

  1. Begin: To start, pour one cup of water into the bottom of the pot and line a seven-inch springform pan with parchment paper. Grease the sides of the cake pan and the paper at the bottom of the pan with cooking spray. 
  2. Melt: Then, add cocoa powder, chocolate, and butter to a microwave-safe bowl and microwave on high for several 40-second intervals, whisking each time, until the chocolate melts. Cook time may vary depending on your microwave.
  3. Mix: Next, add both sugars and salt to the melted chocolate and whisk just to combine. Add the vanilla, coffee, and eggs, one at a time, whisking gently after each egg.
  4. Cover: After, pour the cake batter into your prepared pan and tap it gently to remove air bubbles. Cover with aluminum foil and tuck the ends under the pan. Put a trivet in the bottom and carefully lower the pan into the pot. 
  5. Cook: Then, close the lid and set the pressure release valve to seal. Choose manual and set the cooking time for 50 minutes on high pressure. It will probably take about five minutes before the timer begins. 
  6. Release: After, do a natural release for 10 minutes before moving the valve to quick release the rest of the steam before using potholders or a towel to remove the cake by the trivet handles. 
  7. Remove: Last, remove the foil and check for doneness. The middle should jiggle in the center like a set Jell-o. If it is still liquid, cook for another five or 10 minutes. Blot the top with a paper towel to absorb condensation and let it cool on a cooling rack for about two hours. 
  8. Serve: Finally, remove the cake and garnish with cocoa and whipped cream before serving. 

Recipe variations:

  • Other fats: Feel free to try other butter or oil like coconut oil.
  • Espresso: Alternatively, you can use espresso powder instead of coffee. 
  • More chocolate: For the chocolate lover, add chocolate syrup and semisweet chips to the top of this rich chocolate cake. 
  • Nuts: You can also add a cup of chopped walnuts or pecans for a crunchier cake.
  • No coffee: Skip the coffee if you do not like that flavor. 
  • Other flavors: Experiment with other flavors using different extracts like almond, lemon, and lavender.

How to serve:

You can serve this as a perfect dessert with any meal or the next time you need to satisfy your sweet tooth. Or try one of these serving suggestions:

  • Sprinkle with red dusting sugar or use red frosting to decorate and serve for Valentine’s Day. 
  • Strawberry sauce would make a delicious topping for this dense cake too.
  • Add a dollop of vanilla ice cream to the top of or next to the cake. 
  • Another way to enjoy this keto cake is with our keto caramel sauce.
  • Top the cake with berries like raspberries, strawberries, or blueberries.

Frequently asked questions

What is a flourless cake?

A flourless cake is great for those with gluten intolerance or those on a keto diet. It can be baked or unbaked and has a creamy and silky texture and flavor.

It is similar to a cheesecake consistency and stays together with eggs and fats. There is very little air in it, so it is a dense and, in this case, fudgy cake.

Can I make this in a slow cooker?

Yes, this dense cake can easily be made in a slow cooker using the water bath method. Put one cup of water into the bottom of the pot and then insert a baking dish that fits inside the cooker.

Cover it and cook for four hours but check after two. The timing depends on the thickness of the baking dish. 

Why did my cake fall?

It happens quite often, especially for flourless cakes because there is no gluten to help them rise or stay risen. However, if your cake puffs up a lot when you cook it and then deflates as it cools, it probably has too much air in it.

The next time you make a flourless cake, be sure to stir it gently and just enough to combine the ingredients. 

How to store leftovers:

  • Store: The instant pot flourless chocolate cake will store well in plastic wrap or an airtight container at room temperature for several days or in the fridge for up to a week. 
  • Freeze: This is one of those cakes you can actually eat frozen and it will stay good for up to a month in the freezer. When you get a chocolate craving, just slice off a tiny piece and it will melt in your mouth.
  • Defrost: Thaw overnight in the refrigerator before serving.
  • Reheat: Reheat in the microwave for 45 seconds or eat chilled.

Cooking tips:

  • If you use salted instead of unsalted butter, make sure you omit the salt in this flourless chocolate cake recipe. 
  • Instead of using the microwave, you can melt the chocolate in a medium-size bowl over a pot of boiling water. 
  • If you do not have a trivet with long handles, use aluminum foil to make a sling. Just fold a long piece of foil and put it under the pot with the sides hanging out for handles. 
  • To easily remove the sides of the springform cake pan, use a paring knife around the edges and then a long knife under the paper to loosen it a bit. 
  • You could also use a little almond flour on bottom of the pan to keep it from sticking to the parchment liner.
