Grease and flour a Bundt pan. Do not preheat the oven.

Mix flour, baking powder, and salt together in a bowl.

Cream sugar and butter in a large bowl with an electric mixer until light and fluffy. Add eggs, one at a time, beating well after each addition. Add vanilla. Add flour mixture alternately with milk; beat until smooth. Pour batter into the prepared pan.

Place cake into the cold oven. Set the temperature to 350 degrees F (175 degrees C); bake until a toothpick inserted into the center comes out clean, 1 to 1 1/2 hours. Cool on a wire rack for 5 minutes. Run a table knife around the edges to loosen. Invert carefully onto a serving plate or cooling rack. Let cool completely, 20 to 30 minutes.
