Make simple syrup by following the directions in this post.
Place fruit in a blender or food processor and puree until smooth.
Strain fruit puree through a mesh strainer.
Combine the strained fruit with half of the simple syrup.
Add the rest of the simple syrup and vanilla to the coconut milk.
Alternate layers of the berry mixture and the coconut milk mixture to the popsicle molds, starting with the berries.
Place the popsicle molds in the freezer until frozen through.
For a Blended Creamy Berry Popsicle: Stir the coconut milk and berry puree mixtures together, then divide the mixture evenly between the popsicle molds. Freeze until firm.Berry Options: Use any combination of berries (or even a single berry will work) you like, adjusting the sweetness level as necessary with more or less simple syrup. The sweetness of the popsicle will mellow a bit when frozen, so keep that in mind.Sweetener Options: You can substitute and healthier sweetener like agave, maple syrup, or honey if you like.Coconut Milk Notes: Full-fat coconut milk is best for this (and most) recipes since it will result in a creamier texture that is more like regular cream. You can use lower fat-content coconut milk, but the results will be less creamy and more "icy."
