Prepare the silicone molds by placing them on a baking tray to catch any drips.
In a double boiler or microwave, melt the milk chocolate chips until smooth. If using a microwave, heat in 30-second intervals, stirring in between.
Once melted, use a spoon or spatula to coat the inside of each egg mold with a layer of the melted milk chocolate. Make sure to cover the edges well. Refrigerate for about 10-15 minutes until set.
After the first layer is set, apply a second layer of melted milk chocolate to make the eggs more sturdy. Return to the refrigerator for another 10-15 minutes.
Once the chocolate interior is firm, carefully fill each egg with your desired filling, leaving a bit of space at the top.
Melt the dark chocolate chips using the same method as before. Spoon or pipe the dark chocolate over each filled egg to cover completely.
If desired, sprinkle decorations on top of the dark chocolate while it's still wet.
Place the filled eggs back in the refrigerator for 15-20 minutes to set completely.
Once fully set, carefully remove the chocolate eggs from the molds and serve.
