Preheat oven to 375ºF. In a large bowl, mix together all dry ingredients: flour, sugar, baking powder and salt. Using a pastry cutter or fork, cut solid coconut oil into the flour. In a separate bowl, mix together wet ingredients (not coconut oil): egg, coconut milk, vanilla extract and almond extract. Create a well in the bowl with the dry mixture and pour the wet mixture into it. Fold together without over-mixing and stir in the fresh mango chunks. Form a circular mound with the dough, scoring into 8 triangular pieces (like a pizza). Add a sprinkle of sugar over the dough. Bake for 15 minutes, separate the pieces and bake for another 10-15 minutes until a toothpick comes out clean.
