Ingredients needed:

Scroll down to get the exact measurements from our recipe card. But here are the basic ingredients for these molten cakes:

  • Butter: Cut into cubes.
  • Chocolate chips: Semisweet is what I used, but you can make this dessert with milk chocolate or even white chocolate. 
  • Powdered sugar: Also known as confectioners’ sugar.
  • Large eggs: At room temperature.
  • Egg yolk: Also at room temperature.
  • Vanilla: Pure vanilla extract.
  • Cocoa powder: We always go for high-quality, unsweetened cocoa powder.
  • Espresso powder
  • All purpose flour
  • Kosher salt
  • Peanut butter: Divided.
  • 1 cup of water: For the pot, but if you have a large or a smaller pressure cooker, use the minimum amount of water recommended for it.

How to make instant pot peanut butter lava cake recipe?

  1. Grease: First, grease your ramekins with butter or nonstick cooking spray. 
  2. Melt: Then, melt chocolate chips and butter in a small bowl in 30-second bursts until melted.
  3. Mix: Next, add the vanilla, egg yolk, eggs, and powdered sugar and whisk until smooth. Then add the cocoa powder, espresso, flour, and salt. Whist just until combined. 
  4. Pour: Immediately, fill the prepared ramekins halfway with batter and top with a heaping tablespoon of peanut butter before covering with the remaining batter. Cover ramekins with foil. 
  5. Stack: After putting your trivet inside the pot, pour one cup water. Then put three of your little cakes on the trivet and the final one on top of the others. 
  6. Cook: Next, secure the lid and set your pressure cooker to high pressure for 20 minutes. Then do a quick release, waiting until it is finished before opening. 
  7. Remove: Right away, use your tongs to remove the ramekins. Uncover and run a knife or spatula around the edges. Turn onto a plate and dust with powdered sugar. 
  8. Serve: Finally, serve your molten lava cake while still warm. 

Recipe variations:

  • Other chocolate: Alternatively, you can use dark chocolate or milk chocolate instead of semisweet. 
  • Peanut butter lovers: Use peanut butter chips instead of chocolate chips for even more flavor. 
  • Fruity: Feel free to add some fruit filling like strawberry or raspberry to the chocolate mixture to make PB&J lava cakes. 
  • Make it crunchy: Use crunchy peanut butter for some crunchiness.
  • Nutty: Similarly, you can add walnuts, pecans, or peanuts to the batter for more nuttiness.
  • Make it bigger: Instead of using ramekins, make one large instant pot cake with a 7-inch cake pan.

Frequently asked questions

What is an instant pot?

Similar to an electric pressure cooker, this device cooks at a higher pressure, increasing the temperature and retaining moisture.

The best part is you will notice the first time that it is safer than the old-fashioned pressure cooker and you do not have to use it on the stovetop. 

How do you know when lava cake is done? 

Since the instant pot lava cake has a gooey center, you cannot use the toothpick method.

The best way to make sure it is cooked to perfection is to follow the instructions to the letter. Also, when the edges are cooked, and the center has risen. It should be soft but not jiggly. 

Why isn’t my lava center runny?

If your molten chocolate cake is not gooey enough, you may have cooked it too long. Next time, reduce the cooking time to one minute and see if that works.

If not, reduce it to another minute. Another reason the middle may not be gooey is that you added too much flour. 

How to store leftovers:

  1. Store: Store this perfect dessert in a covered container in the fridge for up to three days. 
  2. Freeze: Freezing is not recommended.
  3. Reheat: For best results, reheat in an oven preheated to 350 degrees F for about 10 minutes.

Cooking tips:

  • Cook time may vary depending on the size of your pot.
  • Similarly, the cooking time will be longer if you are at a higher altitude. Add 5% cooking time for every 1,000 feet you are above 2,000. 
  • Use a silicone sling to make removing your cakes easier. 
  • If you do not have a silicone sling, you can make a foil sling. 
  • Alternatively, use a cake mix instead of powders and flour.
