Grease 6 mini muffin tin spots with baking spray or line with mini-muffin paper cups.
Melt chocolate chips over a double boiler or in a small bowl in the microwave.
Add melted coconut oil once chocolate is almost fully melted and stir to thin out and incorporate fully into chocolate.
Spoon half the chocolate mixture into the bottom of the muffin tins.
Using a pastry brush, brush the chocolate up the sides of the tins a bit. (If you greased the tin, it will take some persistence to get the chocolate to stick to the sides but do not skip the greasing step otherwise it will be very difficult to get the chocolate out later).
Freeze for about 20 minutes.
Meanwhile, combine strawberries and water in a food processor and pulse until it reaches the consistency of jam.
Transfer to a small bowl and stir in the chia seeds. Set aside.
Remove muffin tin from freezer and spoon half a teaspoon of almond butter into each muffin tin. Then layer on half a teaspoon of the strawberry chia jam on top of that (you will have extra jam).
Freeze again for another 20 minutes.
Remove from freezer and spoon remaining chocolate (you may have to reheat again slightly) on top.
Sprinkle with sea salt if using and freeze one last time for 10-15 minutes.
Remove from freezer and using a knife, carefully pop out chocolate cups from tin.
