Instructions
Make the cake
Preheat the oven to 350℉ and lightly grease and line a loaf pan with parchment paper. See notes for other pan sizes.
In a large bowl, mix flour, sugar, baking powder and salt. In a separate bowl, whisk eggs, milk and oil.
With a rubber spatula, stir the wet ingredients into the dry ingredients just until moistened. (just like pancakes! do not over mix).
Wash and dry the fresh blueberries (no need to wash or thaw frozen blueberries if using) and toss them in a bowl with the 2 tablespoons of flour. This will prevent the blueberries from falling to the bottom of the cake. Fold them into the cake, be careful to not overmix or you will break the blueberries and batter will turn blue.
Pour the batter into the prepared pan. Sprinkle the top of the cake with the coconut and bake for 50-60 minutes or until a toothpick inserted in the center comes out clean. During the last 10 minutes, check your loaf, if the coconut starts to brown more than a golden brown, cover the top with foil and continue baking. Bake time will depend on cake size. Cool the cake in the pan on a wire rack.
Remove the cake from the oven and let cool for at least 15 minutes before unmolding the loaf. If made in a 9x13in pan, you can leave it in the pan, cut and serve directly from it.
Make the sauce
For the sauce, in a small saucepan combine the sugar, cornstarch and grated lime zest. Whisk in the water until well blended.
Bring the mixture to a boil over medium-low heat, stirring frequently to avoid burning. Cook for about 2 minutes at a boil until the mixture is bubbly and thick.
Remove pan from the heat and stir in the butter and lime juice. Reserve in a glass container or serve immediately. You may need to reheat it or stir with adding a bit of water if the sauce thickens too much when cold.
Drizzle each piece with lime sauce before serving.
