Instant Pot Molten Chocolate Bundt Cake. A chocolate cake from a pressure cooker? Yes, you can. And yes, it’s good.



  • ⅔ cup (80g) flour
  • ½ cup (42g) cocoa powder
  • 1 teaspoon (4g) baking powder
  • ½ cup (113g) butter, softened
  • ½ cup (99g) sugar
  • ½ teaspoon (9g) salt
  • 2 large eggs (100g)
  • 1 teaspoon (5g) vanilla
  • 1 cup (170g) chocolate chips
  • Baking spray (for pan)
  • 2 cups (500ml) water (for the pressure cooker)

Glaze (optional)

  • ¼ cup (28g) powdered sugar (plus more if needed)
  • 1 tablespoon milk (plus more if needed)


Soften the butter: Soften the butter by leaving it out at room temperature for at least 1 hour. 

Make the cake batter: In a small bowl, mix the flour, cocoa powder, and baking powder until completely combined, and set aside for later. Beat the butter in an electric mixer at medium speed for 1 minute, until smooth. Add the sugar and salt and beat on medium-high until it turns light and fluffy, about 2 minutes. Stop the mixer and scrape down the sides of the bowl with a spatula. Set the speed to medium-low and add the eggs one at a time until well combined, about 1 minute each. Add the vanilla, then slowly add the flour-cocoa mix, beating on low until just combined, about 2 minutes. Scrape down the sides of the bowl again, then stir in the chocolate chips by hand.

Prep and fill the bundt pan: Spray the inside of the bundt pan with baking spray. Scoop the batter into the pan, cover the pan with a piece of aluminum foil, and crimp around the edge to seal.

Pressure cook the bundt cake for 35 minutes with a quick release: Put the cooking rack in the pressure cooker pot, then pour in 2 cups of water. Carefully lower the bundt pan into the pot, setting it on the rack. Lock the lid on the cooker and cook on high pressure for 35 minutes (“Manual” or “Pressure Cook” mode in an Instant Pot), or for 30 minutes in a stovetop PC. Quick release the pressure.

Let the cake rest for 5 minutes, then invert, glaze, and serve: Remove the bundt pan from the cooker and let it rest for 5 minutes. Remove the foil, and flip the bunt pan upside down onto a serving plate. The cake should release; if it doesn’t, use a small spatula or butter knife to work the edges of the cake loose from the bundt pan (especially the middle tube), and try inverting it again. Mix the sugar and milk until you have a smooth glaze. Spoon the glaze over the cake, then slice and serve.


  • Why spray the pan when the cake pan is nonstick? Maybe it is part of “not being a baker”, as I described above, but cakes always stick to the pan when I’m around. I spray the pan as insurance, to make sure it releases.
  • The glaze may need adjusting. If it’s too thin, add more powdered sugar, a little at a time; if it’s too thick, add more milk.
  • If you don’t have powdered sugar, you can make it with a food processor and regular (granulated) sugar – just process it for a minute, then let it settle.
