Preheat the oven to 350°F and grease two 9-inch round cake pans. Line with parchment paper if you're feeling fancy.
In a bowl, whisk together the flour, baking powder, and salt. Nothing complicated, just your dry stuff hangin' out.
Cream the butter and sugar until light and fluffy. Think 'pillow-soft clouds' but edible.
Add the eggs one at a time, beating after each. Then throw in the vanilla like you mean it.
Alternately add the flour mixture and milk, starting and ending with the flour. Mix just until it comes together—don’t overthink it.
Divide the batter between the pans and smooth the tops. Bake for 30 to 35 minutes or until a toothpick comes out clean-ish.
Cool in pans for 10 minutes, then turn out onto a wire rack. Try not to eat them warm—unless you're into that (I definitely am).
