Use an immersion blender (or traditional blender) to blend mango, coconut milk, honey, and vanilla.
Pour mixture into approximately 8 popsicle molds, filling 3/4 of the way full. Save some of the mixture so you'll be able to top them off.
Add raspberries and use a chopstick or skewer to press them down into the mold and swirl them around a bit.
Finish filling the popsicle molds, add popsicle sticks, freeze for several hours till set.
