Set your oven to 350°F and allow it to fully heat up before baking.
02 -
In a bowl, mix together your flour, baking powder, baking soda, and kosher salt until well combined. Set this mixture aside for later.
03 -
In a separate smaller bowl, stir together the room temperature sour cream and whole milk until smooth. Set this aside as well.
04 -
Add your room temperature butter to your mixer bowl and beat on high speed for about 4-5 minutes. You'll know it's ready when it's noticeably lighter in color and has a fluffy texture.
05 -
Pour in the granulated sugar and continue beating on high for another 2 minutes until the mixture is light and well incorporated.
06 -
Add eggs one at a time, making sure each is fully mixed in before adding the next. Then mix in the vanilla extract until just combined.
07 -
Using a spatula, gently fold the flour mixture into your butter mixture in three separate additions, alternating with the sour cream mixture. Be careful not to overmix - stop as soon as the ingredients are just combined.
08 -
Line your cupcake pans with paper liners. Using a 3-tablespoon scoop, fill each liner about two-thirds full with batter.
09 -
Place your cupcake pans on the middle rack and bake for 12-14 minutes. You can test for doneness by inserting a toothpick into the center of a cupcake - if it comes out clean with no batter, they're ready.

Take the pans out of the oven and place them on a wire cooling rack. Allow the cupcakes to cool completely before adding your favorite frosting.
