For glaze, combine butter, brown sugar, 2 tablespoons vodka, vanilla, salt and color in small saucepan. Bring to a boil over medium-high heat, stirring constantly, and boil 30 seconds. Remove from heat and whisk in confectioners' sugar and remaining 1 tablespoon vodka until smooth. Let cool 3-5 minutes (glaze will thicken as it cools); drizzle over cakes.
Pair these cakes with Tito's Handmade Vodka The Velvet Hammer cocktail for a sinfully rich pairing.
