In a heatproof bowl, combine the white chocolate, butter, lemon zest, and heavy cream. Melt gently over a pot of simmering water (double boiler) or in the microwave in 20-second bursts, stirring until smooth. Spoon the mixture into 6 small silicone molds or an ice cube tray. Freeze for at least 1 hour, until solid.

Preheat the oven to 190°C (375°F). Grease 6 mini ramekins or muffin tin wells and line the bottoms with rounds of parchment paper.

In a medium bowl, cream the softened butter and sugar together until pale and fluffy. Beat in the eggs, one at a time, mixing well after each addition. Add vanilla extract, lemon zest, and lemon juice, and mix to combine.

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture until just combined.

Spoon about 1 tablespoon of batter into the bottom of each prepared ramekin. Place a frozen white chocolate center in the middle of each, then cover with the remaining batter, ensuring the centers are fully enclosed.

Bake for 11–13 minutes, until the edges are set but the centers remain slightly soft. The tops should spring back lightly when pressed.

Let the cakes cool in the ramekins for 2 minutes, then carefully run a knife around the edges and invert onto serving plates. Garnish with lemon zest curls, edible flowers, and a dusting of powdered sugar if desired. Serve immediately for the best molten center.
