Combine coconut yogurt, milk, lime juice and sweetener (optional) in a bowl with a spout, so it’s easy to pour, and mix well.
Drop two blueberries and two raspberries at the very bottom of each popsicle mold.
Fill the popsicles half-way with the coconut yogurt mixture.
Add 2 more blueberries and raspberries in the middle.
Fill almost to the top and again, add 2 of each fruit.
Place the top cover over the popsicle mold.
Carefully place the sticks in the center hole of the mold – more than halfway the popsicle, but not all the way to the top. Also remember to leave enough room at the end of the stick for someone to hold in their hand.
Place in the freezer for 5 hours or overnight.
When removing, allow the popsicles to sit out for 10 minutes and slowly remove by gently wiggling them side-to-side.
