  • 1/2 cup butter cubed
  • 1 4 oz semi-sweet chocolate bar chopped (I like Bakers chocolate)
  • 3/4 cup powdered sugar
  • 3 eggs
  • 1 egg yolk
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 3 tbsp flour
  • 3 tbsp graham cracker crumbs plus extra for topping
  • 4 tbsp marshmallow creme plus extra for topping


  • Add butter and chocolate to a large, microwave safe bowl. Heat for 30 second intervals, stirring well between each time. (1-1 1/2 minutes will be enough.) Stir until completely smooth.
  • Add powdered sugar and stir until smooth again.
  • Add eggs, egg yolk, vanilla and salt, stirring to combine.
  • Stir in flour and graham cracker crumbs.
  • Spray (4) 6 ounce ramekins with cooking spray. Fill 1/3 of the way and then add a scoop (about 1 tbsp) of marshmallow creme in the center of the batter. Top with additional batter until each ramekin is full to the line. Don't overfill, as they do puff up a bit when cooking. There may be a bit of batter left in the bowl, depending on how much marshmallow creme you use.
  • Place trivet in the pot and add 1 cup of water. Set 3 ramekins down on the trivet and then set the last one on top.
  • Close and lock the lid, turning the steam release valve to closed. Press Steam and adjust time down to 8 minutes. Press Start/Stop.
  • When cooking cycle is done, do a quick release and carefully remove the ramekins. (I used tongs for this.) Let them cool for 1-2 minutes.
  • Invert the ramekins onto a plate and let the cake slide out. Top with additional marshmallow creme and graham cracker crumbs. Serve immediately!


For a regular chocolate lava cake, replace the 3 tbsp of graham crackers with 3 tbsp of flour and eliminate the marshmallow creme. Cook as directed and serve topped with powdered sugar or ice cream! 
This recipe was tested in a 6 quart Crockpot Express using standard porcelain 6 ounce ramekins. For an 8 quart cooker, use 1 1/2 cups of water and the 4 ramekins should nestle right next to each other inside the pot. Cook time may be a bit less. Start with 7 minutes and adjust as needed.
