Make this adorable heart-shaped instant pot chocolate cake for your next special occasion. It’s perfectly moist and chocolatey with the yummiest chocolate ganache.

I love making desserts in my instant pot. I have made funfetti cake, peanut butter cup cheesecake, cherry cobbler, Oreo cheesecake, peach cobbler, and apple crisp. This chocolate cake might just be my favorite. It is so rich and delicious and I absolutely love how it turns out as a heart-shaped cake. If you are looking for more instant pot recipes, you might be interested in my cookbook.

Where do I find the heart-shaped pan?

The pan we used is the heart-shaped fluted pan made by Wilton. It is an 8-inch pan and can be purchased on Amazon.

Will the pan fit inside a 6 quart instant pot? 

No. Unfortunately, this heart-shaped pan only fits in the 8 quart instant pot. If you have a 6 quart instant pot, you can still make this cake in the Nordic Ware 6-cup bundt pan (which I own and love). Alternately, you can try and find a 7-inch hart shaped pan, or two smaller pans and make two smaller cakes.

How to make chocolate cake in a pressure cooker?

This chocolate cake is very easy to make. We use a cake mix to save time and then top it with an easy homemade chocolate ganache and tasty sprinkles to make it look (and taste) extra special. 

Can I freeze instant pot chocolate cake?

You sure can! Make sure the chocolate cake is fully cooled down. Wrap it in two layers of foil, label, and freeze up to 3 months. I love freezing individual slices of cake so I can have a little treat when the craving hits. To defrost, simply unwrap and let it come to room temperature for about an hour. Enjoy!
