Ingredients

Instructions

  1. Keep the cakes frozen or refrigerated until ready to eat. For best quality, use within 7 days.
  2. If frozen, thaw in the refrigerator (40°F) overnight or at room temperature for 2-3 hours before cooking.
  3. Remove and discard the plastic wrapping from each cake.
  4. For oven: Preheat oven to 350°F. Place thawed cakes on a baking sheet and bake until warmed through, 10-14 minutes. (Oven times may vary.)
  5. For microwave: Place thawed cake on a microwave-safe plate. Microwave until warmed through, 30-45 seconds. Do not overheat.

Recipe Tips

For a gooey center, avoid overcooking. Start with the minimum time and add seconds as needed.

Let the cake rest for 1 minute after microwaving to allow the center to set slightly.

Enhance with toppings like vanilla ice cream, chopped peanuts or a drizzle of extra peanut butter.

FAQ

Can I cook these lava cakes from frozen?

It’s best to thaw them first for even heating. Thaw in the refrigerator overnight or at room temperature for 2-3 hours before cooking.

How do I know when the lava cake is done?

The cake should be warm and slightly puffed. For microwave, 30-45 seconds is usually enough. In the oven, 10-14 minutes at 350°F. The center should be molten, not fully set.

Can I double the recipe?

Yes, simply cook two cakes at once. Adjust microwave time slightly if needed or bake both on the same sheet.
