Ingredients
Instructions
- Keep the cakes frozen or refrigerated until ready to eat. For best quality, use within 7 days.
- If frozen, thaw in the refrigerator (40°F) overnight or at room temperature for 2-3 hours before cooking.
- Remove and discard the plastic wrapping from each cake.
- 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.)
- 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.
