Preheat oven to 325 degrees. Coat three 8-inch round cake pans with cooking spray, line bottoms with parchment, and coat again. Whisk together flour, salt, and 1/2 cup sugar. In a separate bowl, combine cream, milk, baking powder, and egg whites. Whisk in vanilla, almond extract, and remaining 1/2 cup sugar.
Fold in flour mixture. Fold in raspberries, then divide among pans. Bake until golden and top springs back when touched, about 25 minutes. (Each cake layer will be approximately 1/2 inch in height.) Let cool in pans 30 minutes. Remove; let cool completely on a wire rack.
Spread half the jam over top of 1 cake layer, and sandwich with another layer. Repeat with remaining jam and layer. Swirl frosting over top and sides of cake. Sprinkle top with coconut.
