Fill the bundt cake wells and bake according to the recipe.
Remove the cakes from the oven. Let cool in the pans 10 -15 minutes before removing them.
Transfer the cakes to a wire baking rack fitted over a baking sheet lined with parchment paper.
Let the cakes cool completely.
Trim the bottoms of the cakes off so that the cake sits evenly on a flat surface.
In a small pitcher, whisk together the powdered sugar, milk, and vanilla extract.
Slowly pour the icing over each little cake. While the icing is still wet, push the eyes into place. Keep an eye (haha) on the eyes to make sure they don't slip as the icing is drying.
