Preheat the oven to 350°F.
Thoroughly grease a 10-inch bundt pan, ensuring all ridges and inner surfaces are well coated.
Place the Nilla wafers in a large resealable plastic bag.
Seal the bag securely and crush the wafers with a rolling pin or wooden spoon until fine crumbs form.
Set the crushed wafer crumbs aside.
In a large mixing bowl, combine the softened butter and granulated sugar.
Mix for 1 to 2 minutes, or until the mixture becomes light and airy.
Add the eggs one at a time, mixing well after each addition.
Continue mixing until the eggs are fully incorporated and the batter is smooth.
Add the milk and vanilla extract.
Mix until the liquid ingredients are evenly blended into the batter.
Add the crushed Nilla wafer crumbs to the bowl.
Add the sweetened shredded coconut and chopped pecans.
Fold the mixture gently until the wafer crumbs, coconut, and pecans are fully incorporated.
Transfer the batter into the prepared bundt pan.
Spread the batter evenly in the pan with a spatula.
Place the bundt pan in the preheated oven.
Bake for 45 to 50 minutes, or until the cake is set and a toothpick inserted into the center comes out mostly clean.
During the last 15 to 20 minutes of baking, cover the top loosely with aluminum foil to prevent excessive browning.
Remove the cake from the oven.
Allow the cake to cool in the pan for 10 minutes.
Run a knife gently around the edges and center tube of the bundt pan to loosen the cake.
Place a serving plate over the bundt pan.
Carefully invert the cake onto the serving plate.
Lift the pan away slowly.
Allow the cake to cool to room temperature before slicing.
Slice and serve as desired.
