Add the skimmed milk, strawberry custard and sweetener to a large jug and mix together.
Add the strawberries to the jug and use a food processor or a stick blender to blitz until fully combined.
Pour the milk mixture into 6 ice lolly moulds. Don't overfill the moulds as the mixture will expand in the freezer.
Add the lolly sticks and freeze overnight or until solid.
Add the chocolate to a small bowl and microwave in 30 second bursts, and stir until melted.
Add the mini cupcake to a small bowl and crush into crumbs with your hands then stir through the hundreds and thousands.
Drizzle the top of each ice pop with the melted chocolate and sprinkle over the crushed cake and sprinkles.
