Pre-heat oven to 375°F. Line 24 cupcakes.
In a large bowl, sift together flour, salt, baking powder, and baking soda. Using an electric mixer, beat butter. Add in sugar and continue to cream together. Add eggs one at a time until mixed.
Alternate adding dry ingredients and milk, beginning and ending with the dry ingredients; mix until just together. Stir in vanilla and sprinkles.
Fill cupcake liners approximately 2/3 full. Bake for 15-17 minutes; remove from oven when cupcakes are set and bounce back when lightly touched. Remove from pan and let cool.
