Preheat your oven to 350°F (175°C) and line a cupcake tin with liners.
In a mixing bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition.
Mix in the vanilla extract, sweet tea, and milk.
In another bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Divide the batter evenly among the cupcake liners, filling each about ⅔ full.
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Let the cupcakes cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
For the frosting, beat the butter until creamy. Gradually add the powdered sugar, moonshine, milk, and vanilla extract, beating until smooth and fluffy.
Frost the cooled cupcakes with the moonshine frosting.
