I'd advise tempering the chocolate (if you have the patience!) to help get a nice shiny finish. The seeding method is an easy (although I'll admit quite time-consuming) way to do that. You just need a candy thermometer to make sure you hit all the right temperatures. Full instructions on tempering are included in the notes section of this recipe card. If you can't be bothered to temper the chocolate, you can just melt it over a double boiler (bain-marie) and skip to the next step. Melt the chocolate over a double boiler (bain-marie). If using a microwave, heat it in 20-second intervals, being careful not to burn the chocolate.
Place an egg mold with 2.5" cavities on a tray lined with parchment paper. (see notes) Add one tablespoon of melted chocolate to each mold cavity. Using a pastry brush, coat the inside with a thick layer of chocolate, ensuring all sides are covered - the chocolate will pool in the bottom of the molds. Turn the molds upside-down over the lined tray, allowing any excess melted chocolate to drip onto the parchment paper (gather and reserve this for later). Using a pallet knife, carefully sweep across the top of the molds to remove any excess chocolate. Place the filled molds in the freezer to set for 10 minutes.
To make the white filling, add the sweetened condensed coconut milk, powdered sugar, vanilla extract, and sea salt to a medium bowl and whisk until smooth.
For the yellow "yolk" filling, add 3 tablespoons of the white filling mixture along with the ground turmeric to a separate small bowl. Use a fork to mix it well.
Transfer both fillings to 2 separate piping bags, cutting off the bare end tips (you can also simply use a spoon to fill the molds if preferred).
Pipe some of the white filling into each chocolate mold. Next, pipe some of the yellow filling into the center of each mold before topping them off with more of the white mixture. Be careful not to overfill the molds and leave enough space for the final chocolate layer.
Finally, spoon the remaining melted chocolate over each filling to seal off the creme eggs. Place them back in the freezer to set completely for another 10 minutes. Once set, carefully remove the eggs from their molds.
If you have leftover melted chocolate, you can drizzle it over the eggs once completely set and sprinkle them with some flaky sea salt.
