Creating the Christmas Coconut Snow Cake is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour three 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, baking powder, and salt.
3. Cream Butter and Sugar: In another bowl, cream the softened butter and granulated sugar until light and fluffy.
4. Add Eggs: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
5. Combine Wet Ingredients: Add the milk, vanilla extract, and coconut extract to the butter mixture. Mix until smooth.
6. Add Dry Ingredients: Gradually add the dry mixture to the wet mixture, stirring until just combined.
7. Fold in Coconut: Gently fold in the shredded coconut until evenly distributed.
8. Divide Batter: Divide the batter evenly among the prepared cake pans.
9. Bake: Place in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
10. Cool Cakes: Remove from the oven and allow the cakes to cool in their pans for about 10 minutes. Then, transfer them to wire racks to cool completely.
11. Prepare Frosting: In a mixing bowl, whip the heavy cream until soft peaks form. Gradually add the powdered sugar and continue whipping until stiff peaks form.
12. Assemble the Cake: Place one layer on a cake stand or serving platter. Spread a layer of whipped cream frosting on top. Repeat with the second layer, then place the third layer on top.
13. Frost the Sides: Frost the top and sides of the cake with the remaining whipped cream.
14. Decorate: Generously sprinkle shredded coconut over the top and sides for a snowy effect.

These steps will lead you to create a stunning Christmas Coconut Snow Cake that will delight everyone at your holiday gathering.
