Butter the muffin pan and preheat oven to 350°.
In a bowl, sift together flour, baking powder, and baking soda. Set aside.
Beat together butter and sugar in a large bowl until light and fluffy. Add eggs and vanilla , mixing until combined.
Gradually add the dry ingredients and mix just until incorporated. Do not overmix.
Divide the batter between 10 muffin wells and and smooth the tops. Bake for 15–20 minutes, or until a toothpick inserted in the center comes out clean.
Let cool in the pan for 10-15 minutes, then transfer cakes on the wire rack to cool completely.
