Marshmallow Lava Cake

Hey there friends! Welcome to almost June! I know, I know; I can’t believe we are already this far into 2022. But that means we have a very important holiday coming up in just a few short days; Memorial Day, the unofficial start to summer! Well, this is mostly for those of us in the USA. 

Anyway, let’s get to this Marshmallow Lava cake. I always think of summer when I think of marshmallows. Nothing beats roasted marshmallows and chocolate!! So these marshmallow lava cakes are exactly that. Summer in a mouthful. 

Marshmallow Lava Cake

This Marshmallow Lava Cake is what chocolate lovers are craving on Sunday. This recipe creates 6 single-serving beautiful cakes made with a combination of chocolate cake and marshmallow souffle. The gooey center flows just like a fluffy volcano onto your plate when you pull apart the cake with your fork. It’s a beautiful surprise that anyone will enjoy. Who doesn’t want a surprise inside their dessert? 

Not only is this Marshmallow Lava Cake absolutely delicious and rich, but it only uses a few simple ingredients and can be whipped up quickly. So don’t fret! If you don’t have any plans yet, this is your ticket!

The filling uses your favorite childhood sandwich ingredient; marshmallow fluff. The sticky, sugary mixture has the same great taste as a traditional marshmallow because it is easier to bake with because the consistency has been melted down already. 

Now that your mouth is watering let’s get into baking your individual Marshmallow Lava Cake.

Gather your ingredients. Grease your pans and set them aside.

Marshmallow Lava Cake
Yield: 6 servings

Marshmallow Lava Cake

Prep Time 10 minutes
Cook Time 11 minutes
Total Time 21 minutes


  • 1 ¼ cup semi-sweet chocolate chips (you can also use chocolate bars)
  • ½ cup unsalted butter
  • 2 large eggs, room temperature
  • 2 large egg yolks, room temperature
  • ½ cup powdered sugar
  • ¼ cup all-purpose flour
  • ¾ cup marshmallow fluff


  1. Preheat the oven to 425 degrees Fahrenheit and coat a small muffin tin with butter and cocoa powder. 
  2. In a small bowl, melt the chocolate chips and butter in the microwave at 40-second intervals, being sure to stir the ingredients thoroughly after each interval.
  3. Whisk in the eggs and egg yolks until they are fully incorporated into the chocolate mixture.
  4. Gently fold in the powdered sugar and flour until the batter is homogenous and no clumps of dry ingredients remain.
  5. Pour half of the batter into the cupcake tin and then place of a spoonful of marshmallow fluff in each mold. 
  6. Cover the marshmallow fluff with the remaining batter and bake the cakes for 11 minutes.
  7. Allow the cakes to cool slightly before removing, serve, and enjoy!


  • You can serve these cakes alone, with powdered sugar, whipped cream, or ice cream. The possibilities are limitless!
  • It is important to coat the muffin tin in butter and cocoa powder to ensure that the cakes do not stick when you try to take them out. They will break open if they stick too much, and the chocolate marshmallow filling will be quite messy.
  • Sometimes the marshmallow fills with breaks through the top of the cake. This is okay because they are served upside down, so if the top looks a little messy, your guests will not even see it.
  • These cakes can be stored on the counter or in the fridge for up to 3 days in an airtight container.
