To start, preheat the oven to 180 degrees Celsius. Then line a baking tray with baking paper. Place the sugar, flour, shredded coconut and rolled oats in a bowl and stir to combine. Add the butter and use a round bladed knife to stir until just combined and spoon the mixture onto the line tray. Pop in the oven and bake, stirring occasionally, for 30 minutes or until golden. Stir in the dried mango and set aside to cool.
Meanwhile melt the extra butter in a non-stick frying pan over medium heat. Add the fresh mango, extra sugar and vanilla extract. Cook, stirring occasionally, for five minutes or until the mixture is golden and caramelised. Sprinkle with salt and set aside to cool. Next, grease a 20 centimetre square cake pan and line the base and sides with baking paper, allowing the sides to overhang. Sprinkle half the oat mixture over the base of the lined pan.
Pop in the freezer for 30 minutes to chill. Then combine the ice cream and coconut cream in a bowl, Add the salted mango mixture and gently swirl to marble. Spoon the ice cream mixture over the oat mixture in the pan and then smooth the surface. Sprinkle with the remaining oat mixture pressing down gently. Place in the freezer for four hours or until firm.
To serve, cut into pieces and serve immediately. These salted mango and coconut ice cream crumble bars are a perfect warm weather treat.
