Step-by-Step Instructions
- Prepare the Chocolate Centers:
- Use a heatproof bowl to melt white chocolate butter lemon zest and cream together either over a simmering pot or in the microwave stirring often until fully smooth. Portion into small silicone molds or ice cube tray cavities. Place in the freezer for at least one hour so the centers become solid enough to enclose in the cake batter.
- Preheat the Oven and Prepare Ramekins:
- Set your oven to 190 degrees Celsius or 375 degrees Fahrenheit. Grease six mini ramekins or muffin tin wells generously and line each bottom with a round of parchment paper to ensure the cakes release without sticking.
- Cream the Butter and Sugar:
- In a medium mixing bowl work the softened butter and sugar together until very light and fluffy using a hand mixer or stand mixer. Commit to creaming for several minutes to trap air and help your cakes rise.
- Add Eggs and Flavorings:
- Add eggs one at a time mixing well after each so your batter stays smooth. Mix in vanilla extract lemon zest and lemon juice ensuring everything is fully incorporated for lively citrus flavor.
- Combine Dry Ingredients:
- In a separate bowl whisk flour baking powder and salt to evenly disperse the leavening. Gently fold this into the wet mixture in batches mixing only until just combined to maintain a tender crumb.
- Assemble the Cakes:
- Spoon about a tablespoon of batter into each prepared ramekin to form the base. Place one frozen chocolate center in the middle of each then divide and gently spoon the remaining batter on top completely encasing the center.
- Bake the Cakes:
- Transfer ramekins to the oven and bake for eleven to thirteen minutes just until the edges are set but the centers are still slightly soft. The tops should spring back when touched gently.
- Cool and Unmold:
- Remove cakes from the oven and let them stand in the ramekins for two minutes before running a sharp knife around each edge. Invert onto plates to release.
- Garnish and Serve:
- Add curls of lemon zest edible flowers or dust with powdered sugar if you like. Serve right away to enjoy the molten center at its best.

One of my favorite moments is watching my family gather around the table waiting to see the lava run out. My favorite ingredient here is definitely the lemon zest because it smells so bright and sunny as I zest it the whole kitchen smells amazing.
Storage Tips
If you have leftovers let them cool completely and store in an airtight container in the fridge for up to two days. Reheat briefly in the microwave to revive the molten center though the texture is at its absolute best served fresh from the oven.
Ingredient Substitutions
A gluten free flour blend works perfectly if you need a wheat free treat just ensure your blend contains a binder like xanthan gum. For more intense lemon try adding a few drops of lemon extract to the batter. Dairy free white chocolate and plant butter can work in the centers but the end result may not be quite as creamy.
Serving Suggestions
Pair with fresh berries or a scoop of vanilla ice cream for an extra cool contrast to the warm lava center. If you are entertaining pour a glass of Moscato or sparkling Champagne for a celebratory finish.

Cultural and Historical Context
Lava cakes have roots in both French and American culinary history but this version takes its inspiration from the classic chocolate fondant and infuses it with European flavors of citrus and white chocolate. Lemon and white chocolate together are a staple in many European desserts from tarts to cakes.
