Add vodka, creme de cacao, chocolate liqueur, Irish cream, orange juice, and lemon juice to a shaker filled with ice.
Shake vigorously for 15 seconds until cold.
Strain into chilled martini glass.
Garnish with orange peel or a dusting of cocoa powder if desired.
Notes
Use fresh citrus for the brightest flavor. Adjust sweetness by adding extra chocolate liqueur if you like. Chilling your glass keeps the drink cool and creamy longer. Try an orange twist or cocoa powder as garnish for a bar-style finish.
