Preheat oven to 350F. Line cupcake tins with 14 lines (this recipe should make exactly 14 cupcakes)
In a large bowl, whisk together the flour, baking powder, and salt; set aside
In a stand mixer, beat the butter and sugar until light and fluffy. Beat in the eggs one at a time. Add vanilla next, then sour cream; mix until fully combined
Slowly add dry ingredients into wet - mix until just combined, don't over mix the batter
Scoop batter into cupcake liners, filling a little over half way - you should end up with exactly 14 cupcakes
Bake for 18-22 minutes until cake tester comes out clean
Remove from oven and allow to cool for a couple of minutes. Remove from pan to wire rack and allow to cool completely
Frost as desired
