Preheat the oven to 375 degrees F. Line a baking sheet with a silicone baking mat or parchment paper. (We prefer the silicone for the crispy edges and caramelization that occurs with these cookies.)
Lightly whisk the egg and egg white in a medium bowl until a bit frothy. Whisk in the rum and vanilla. Using a rubber spatula, fold in the coconut.
Using about 2 tablespoons per macaroon, mound the mixture on the baking sheet, leaving some space in between each one. Bake until the edges are golden and crispy, about 10 minutes. Cool, then use a small offset spatula to remove them from the baking sheet. The macaroons will keep in an airtight container for 5 days.
