Instant Pot Chocolate Cake with Pumpkin and Coconut Oil

This rich, fudgy chocolate cake gets its moisture from pureed pumpkin and coconut oil, creating a dense, decadent dessert that's naturally sweetened with honey. The Instant Pot steaming method produces an incredibly tender crumb while the overnight chilling firms the texture perfectly for slicing. With unsweetened chocolate and cocoa powder delivering deep chocolate flavor, this cake offers a unique twist on traditional chocolate desserts that works beautifully for special occasions or when you want an impressive dessert without turning on the oven.

FAQ

Can I use a different size pan?

A 7-inch springform pan works best for this recipe. Larger pans may result in a thinner cake that doesn't set properly, while smaller pans may overflow.

What if I don't have a springform pan?

You can use a regular 7-inch round cake pan lined with parchment paper, but removal will be more difficult without the removable sides.

How long does this cake keep?

The cake will keep covered in the refrigerator for up to 5 days. The texture and flavor actually improve after the first day of chilling.
