InstaPot Flourless Chocolate Cake

We felt like having a treat this weekend, so we tried out our flourless chocolate cake recipe using the instant pot. Normally we don't add sugar to our recipes, but in this case, we cheat. Since we are using sweetened chocolate, the chocolate comes with sugar added.


We used the Trader Joe's Pound Plus 72% Dark Belgian Chocolate bar, 1 cup of salted butter, and 8 eggs for the cake. Now, I know that the pound plus is actually 17.6 ounces, not 1 pound, but what's wrong with a little extra chocolate? We used salted butter because that is what we found, but there is nothing wrong with using unsalted butter. One of the reasons for this recipe is that it helps us use up all of those eggs we keep accumulating. In the frosting, we used heavy whipping cream and semi-sweet chocolate chips.


We decided to do as much in the Instant Pot as we could this time. So that means melting the chocolate, both times, in addition to cooking the cake. To melt the chocolate, we basically used the Instant Pot as a double boiler. We added 2 cups of water into the pot, followed by the wire rack and then a heat-resistant (glass) bowl with the dark chocolate and butter. Then, we used the saute function to boil the water and melt the chocolate. We turned the saute off once all of the chocolate was melted and then mixed it until the chocolate caused the butter to melt and mix in smoothly.

kitchenaidWe used the KitchenAid to whip the eggs until they doubled in size, since that seemed like the easiest way to do that. Plus, we needed a larger bowl to combine the eggs and chocolate/butter. Once the eggs were whipped, we folded the chocolate mixture into the eggs. Make sure that the batter is well-mixed.  You are now ready to cook the chocolate cake.


Before cooking, and really before melting the butter, you want to set up the pan. We used a 7" spring form pan (which is the largest that will fit into the Instant Pot). We coated the bottom and sides of the pan with butter (using one of the sticks that ended up with the chocolate). Then, we covered the bottom with parchment paper before closing the pan ring. Lastly, we also coated the parchment paper with butter. So with the pan ready and your batter mixed, you can just pour it in. 

Now, set up your Instant Pot by placing the wire rack such that the handles are underneath and adding 1 cup of water. We then covered the pan with aluminum foil and used a foil sling to place the pan into the Instant Pot. Set your pot to run on manual high pressure for 30 minutes, then allow the pot to sit until natural pressure release.

Once the pressure has been released, remove your pan and uncover it. Then release your pan and turn the cake upside down on a dish. We didn't quite put enough butter on the pan or make our foil sling long enough, which meant we struggled to both remove the pan from the pot and to remove the cake from the pan. You can see the results of that struggle in the above photo. Lesson: do better next time.


The frosting was made in a similar fashion to the previous chocolate melting, but instead we heated the cream first. We used the Instant Pot like a double boiler, heated the cream to steaming, then removed it from heat and added the chocolate chips. We used the hot cream to melt the chocolate and stirred until the cream and chocolate were smoothly mixed. The frosting was then immediately applied to the cake, so that it would cool down and solidify onto the cake. This means that you should allow your cake time to cool down before making your frosting.

Cleaning Up

For me, the best part about baking is that in addition to your finished product, you can lick the bowl as soon as you are finished. Since the frosting was only chocolate and cream, you don't have to worry about those uncooked eggs.

      Go ahead and try it, but make sure that you report back with how it goes. Make sure that you decrease the cooking time though.

      That sounds like a good place to start to me. You should know that I haven't ever actually tried that, so I can only guess.

      If something is weird, I don't see it. Can you be more specific about what you believe is weird? The recipe is exactly what I used.
