Preheat your oven to 350°F (175°C) and grease a mini bundt pan.
In a bowl, whisk together flour, baking powder, and salt.
In another bowl, cream the softened butter and sugar until light and fluffy (about 3 minutes).
Add eggs one at a time, mixing well after each addition; then stir in the vanilla extract.
Gradually combine the dry ingredients with the wet mixture, alternating with milk until smooth.
Fill each bundt cavity two-thirds full and bake for 20-25 minutes or until a toothpick comes out clean.
Allow cooling in the pan for 10 minutes before transferring to a wire rack.
