Add the vanilla vodka, coffee liqueur, amaretto, chocolate sauce, milk and ice to a cocktail shaker.

Shake well.

Place the M&M's in a plastic bag and crush with a rolling pin.

Place the crushed M&M's on a small round rimmed plate. On another round rimmed plate, pour the lemon lime soda.

Dip the rim of a martini glass in the lemon lime soda, then in the crushed M&M’s.

Strain the martini from the cocktail shaker into the glass and serve.
