Place milk and white chocolate in a heat-proof bowl and microwave for 15 seconds. Stir and repeat until chocolate has melted. White chocolate is sensitive to heat, so be careful not to burn the mixture. Alternatively, you can use a bain-marie (that is, place a heatproof bowl over a saucepan of simmering water) to melt it. Let cool to room temperature.
Place white chocolate mixture, yogurt, red chili flaked, tropical heat and strawberries in a blender, and blend until creamy and smooth. Taste and make any wanted adjustments. Add ice cubes and blend until smooth.
Pour into glasses and serve immediately.
*If you use frozen strawberries, you can omit the ice.
