Peanut Butter Chocolate Molten Lava Cakes with Frozen Center

Individual chocolate lava cakes with a surprise frozen peanut butter center that creates an incredible molten contrast when baked. The rich bittersweet chocolate cake encases sweetened peanut butter balls that soften during baking, creating two distinct textures in every bite. Perfect for dinner parties or special occasions when you want to impress guests with a restaurant-quality dessert that can be prepared ahead. The key is freezing the peanut butter centers beforehand so they hold their shape during the short baking time.

Tips
Freeze peanut butter balls longer for better shape retention during baking - overnight is ideal for perfectly molten centers.
Test doneness by gently shaking the pan - centers should jiggle slightly while edges remain set for the perfect lava texture.
Run a knife around edges before flipping to ensure clean release from muffin tin or ramekins.

FAQ
Can I make these without ramekins?
Yes, large muffin tins work perfectly as shown in the recipe. Just butter the wells thoroughly for easy release.
How long do the peanut butter balls need to freeze?
Minimum one hour, but longer is better. Overnight freezing gives the best results for molten centers.
Can I freeze the finished cakes?
These are best served fresh. The molten texture is lost when frozen and reheated.
