Lava Cakes

  • 1 (15.25 oz) box devil's food cake mix*
  • 1 (3.9 oz) box chocolate instant pudding
  • 1 1/4 cups fat free buttermilk room temperature
  • 1/2 cup melted butter
  • 3 large eggs room temperature



  • Heat heavy cream in the microwave until slightly steaming but not simmering, about 90 seconds.
  • Pour over chocolate chips.
  • Stir until melted.
  • Let cool, cover, then refrigerate overnight or until firm (it should still be scoop-able).
  • Keep ganache in the fridge until RIGHT when you’re ready to use it.

Lava Cakes

  • Preheat oven to 350 degrees F and grease 2 (12 slot) non-stick muffin tins with cooking spray.
  • In a large bowl, beat together cake mix, instant pudding, buttermilk, butter, and eggs.
  • Evenly scoop the batter into the prepared pans (about 3 tablespoons or a big cookie scoop worth - should fill 1/2 the muffin tin).
  • Place 1 level tablespoon ganache into the center of the batter and gently press down. It’s ok if the ganache isn’t fully submerged.
  • One pan at a time, bake 15-20 minutes (I did 19 minutes) in preheated oven. The center will still be gooey, but an inserted toothpick in the edge of the cake will come out *mostly* clean.
  • Let the cakes cool for 5 minutes in the pan.
  • Run a knife along the sides of the cakes. 
Place a baking sheet on top of the muffin pan and flip them. The cakes should pop out.**
Serve with powdered sugar, ice cream, whipped cream, hot fudge, etc. and enjoy!

*Basically you’re mixing the cake mix together with the listed ingredients on back of box, but use buttermilk instead of water and butter instead of oil (amounts listed above).
