In a medium saucepan, bring coconut milk, both types of cream, sugar, and vanilla to a boil over medium heat, stirring until sugar is dissolved. Remove from heat and cover for 20 minutes.
Fill a small bowl with 1/4 cup plus 2 tablespoons cold water. Sprinkle gelatin over the water and allow it to bloom (soften), 5 to 10 minutes. Add gelatin mixture to coconut mixture and whisk until combined.
Pour a small amount into the shot glasses (about 1/2-3/4 full) and refrigerate until set, which takes about 2 hours.
