Preheat your oven to 350°F (175°C) and grease a round cake pan or line it with parchment paper.

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

In a large bowl, cream the butter and sugar together until light and fluffy, about 3 minutes.

Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.

Alternately add the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix until just combined.

Add green food coloring to the batter and mix until you achieve the desired shade of green for the 'grass' effect.

Pour the batter into the prepared cake pan and smooth the top with a spatula.

Bake for 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let the cake cool completely before decorating.

Spread a thin layer of vanilla frosting over the top and sides of the cake.

In a bowl, toss the shredded coconut with a few drops of green food coloring until it resembles grass. Sprinkle this coconut evenly over the frosted cake.

Create a 'sand trap' by placing a small section of crushed chocolate sandwich cookies on the coconut 'grass'.

Roll a small piece of white fondant into a ball to create a golf ball. Place it on the cake near the 'sand trap'.

Insert a mini golf flag (optional) into the cake to complete the golf theme.

Serve the cake and enjoy celebrating Father's Day with this fun golf-inspired dessert!
