1Open the coconut milk. Scoop out the solid white part you see on top and place into a mixing bowl. Do not get any of the liquid. Add the sugar. Beat for a few minutes or until stiff peaks form. When you pull the beaters straight up the peaks formed do not fall over. Set aside.
2With the coconut liquid measure out 1/2 cup. If there is leftover liquid left save for another use.
3In a blender add the 12 cup coconut liquid, ice cream and dulce de leche. Blend until smooth. Pour into serving glasses. Top with whipped cream.
