Using a sharp knife, cut one of your apples into 10 even slices, minus the core.
Place 2 toothpicks on either side of the top of your apples, pointed slightly outward.
Place 2 apple slices, with the cut side out, onto the toothpicks to make bunny ears. Pat the ears dry with a paper towel and set aside.
In a medium heat-safe bowl, heat your white chocolate chips according to package instructions until you have smooth white chocolate.
Place a popsicle stick or rod into the center top of the apple and hold your assembled bunny apple over your bowl of white chocolate and spoon the white chocolate evenly over the apple, covering all sides and ears. Set the apple aside, top side up, until the white chocolate has hardened. Repeat this white chocolate process one or two more times until the bunny apples are fully coated in smooth white chocolate and no apple is showing through. Make sure each layer of white chocolate has fully hardened before applying another layer.
Once your last layer has hardened, dip just the bottom inch of the apple in white chocolate and quickly dip it into your sprinkles, rolling it slightly so that the wet white chocolate is covered in sprinkles. Set them aside to harden.
Using a pipping bag or a plastic bag with a hole cut in the corner, pipe a pink icing smile, a dot where the nose will be, and dots where the eyes will be. Place candy eyes and heart sprinkle nose on those icing dots using the icing as glue to hold them on.
Lastly, spread pink icing in the center of each ear using a small knife.
Once all icing and white chocolate has fully hardened, serve at room temperature or chilled.
