Ingredients

Instructions

  1. Keep the lava cakes frozen or refrigerated until ready to eat; best if used within 7 days.
  2. If frozen, thaw in the refrigerator (at 40°F) overnight or for 2-3 hours at room temperature before eating.
  3. Remove and discard the plastic wrapping from the cakes.
  4. Recommended: Preheat oven to 350°F. Bake the thawed cakes in their trays until warmed through, 10-14 minutes. (Oven times may vary.)
  5. Alternative: Microwave the thawed cakes in their trays until warmed through, 30-45 seconds. Do not overheat.

Recipe Tips

For the best texture, do not overheat the cakes-the center should be molten but not boiling.

Serve immediately after heating for the ultimate lava effect.

Top with vanilla ice cream, fresh berries or a drizzle of extra peanut butter for extra decadence.
