Preheat oven to 350°F.
Spray the sides of a 9-inch round pan with oil and line the bottom with 2 layers of parchment. Scatter the blueberries in a single layer in the pan and sprinkle the coconut and 1/2 cup Florida Crystals® Organic Raw Cane Sugar evenly over the top.
Sift or whisk together in a medium bowl the flour, salt, and baking powder.
In a separate bowl, use an electric mixer to cream the butter and remaining 1 cup Florida Crystals® Organic Raw Cane Sugar together. Add eggs one at a time, beating well after each addition.
In a measuring cup combine coconut milk with vanilla, lemon juice, and lemon zest.
On a low speed, alternately add half the dry ingredients, then the coconut milk mixture, and then the remaining dry ingredients. Mix completely after each addition.
Gently spread batter in the prepared pan over the blueberries and coconut. Bake 40 minutes, or until a skewer inserted in the middle comes out clean. Cool at least 15 minutes in pan; then, remove by running a knife around the inside edge of the pan. Invert onto a serving platter. Remove the pan and carefully peel off the parchment paper. Cool completely before serving.
