What You’ll Need

We added a secret ingredient to this peanut butter lava cake to make the center extra luscious and satisfying. Here’s what you’ll need: 

  • Chocolate Cake Mix – Use any boxed chocolate cake mix you like best, and prepare it according to the package instructions. 
  • Chocolate Pudding Mix – We use store-bought pudding mix. However, homemade chocolate pudding works just as well if you have the time to make it.  
  • Peanut Butter – We recommend using natural, creamy peanut butter to create soft, melty swirls. 
  • Chocolate Chips – Semi-sweet chocolate chips help enhance the already rich chocolate flavor. If preferred, dark chocolate chips can be used instead. 
  • Peanut Butter Chocolate Chips – You can never have too much peanut butter, right? Combine these with the chocolate chips for little pockets of smooth peanut butter in every bite. 

How to Make a Slow Cooker Peanut Butter Lava Cake 

This slow-cooker lava cake recipe is unlike any other cake you’ll ever make! It requires a little bit of preparation, but it couldn’t be easier to do. Just follow the steps below. 

  1. Prepare. To begin, cover the bottom of your slow cooker with foil. We don’t do this in the video in the recipe card below. However, after a few rounds of testing, we’ve found that it’s a lifesaver when it comes to preventing the bottom of the cake from burning! 
  2. Gather the Ingredients. Prepare the cake mix and pudding mix according to the package instructions, and round up the rest of the ingredients. 
  3. Layer. Pour the prepared cake batter into the bottom of the foil-lined slow cooker. Add the chocolate pudding on top. Place dollops of peanut butter over the mixture, and use a knife to swirl it around. Sprinkle the chocolate chips and peanut butter chips on top. 
  4. Cook. Cover the slow cooker with the lid, and cook on high for 2 ½ hours. Then, dig in while it’s warm!

Common Questions 

What’s the difference between molten cake and lava cake? 

The terms are often used interchangeably, but they aren’t actually the same desserts. For instance, “molten cake” is a general term that is used to refer to any cake with a soft center that is a combination of chocolate cake and a chocolate soufflé. In contrast, a “lava cake” is a specific type of cake that is made with a slightly underbaked molten chocolate center. 

Can I use different fillings? 

Yes! Feel free to mix and match different cake mixes or pudding mixes to create a completely new recipe. You can even use a different nut or seed butter, chocolate sauce, or caramel sauce for the swirl. 

Can I make this peanut butter lava cake ahead of time?

Serve this peanut butter lava cake right away for the best flavor and texture. However, if you have leftovers, they can be covered and stored at room temperature for 2-3 days. 

Can you reheat leftovers? 

Yes, to warm your slow cooker lava cake, turn the slow cooker to warm. Or, heat individual servings in the microwave in intervals of 20-30 seconds. 

Can I double this slow cooker lava cake recipe? 

If you want to double this recipe, we recommend using two slow cookers or working in batches. Otherwise, it won’t cook properly.
