- baking powder 1 ½ tsp
- baking soda ½ tsp
- salt ½ tsp

🍳 Cookware
- small bowl
- spoon
- stand mixer
- small mixing bowl
- cupcake liners
- cooling rack

1Preheat oven to 350°F (175°C).
-
2In a small bowl , combine granulated sugar and seeds from the vanilla bean . (For those of you who are new to using vanilla beans, watch the video in this post to see how it’s done.)
-
3Using the back of a spoon , move around the bowl and apply pressure to break up any clumps of seeds and to better infuse the vanilla flavor into the sugar. Set aside.
-
4In a medium-sized mixing bowl or bowl of a stand mixer , mix together cake flour , baking powder , baking soda , and salt .
-
5Add the vanilla bean sugar and mix until well combined.
-
6Add unsalted butter and mix on medium-low speed for 3 minutes . Because there is so little butter, you'll end up with a very fine crumb texture.
-
7In a small mixing bowl , whisk together eggs , full-fat sour cream , vegetable oil , and vanilla extract until smooth.
-
8Add the egg mixture to the flour mixture and beat on medium speed until just combined.
-
9Slowly add whole milk and mix on low speed until just combined. The batter will be liquid. (Don't worry, you didn't do anything wrong. It's supposed to be that way.)
-
10Fill cupcake liners just over 1/2 full.
-
11Bake for 14 minutes and then test to see if they are done. They are done when a toothpick comes out without wet batter stuck to it. The cupcakes should appear white with specks of vanilla bean. They should not turn a golden brown. If they are not done, test again in two minutes. If they are still not done, test again in another two minutes.
-
12When the cupcakes are done, remove them immediately from the tins and leave them on a cooling rack (or just on your counter if you don’t own a cooling rack) to cool.
-
13Top with vanilla buttercream frosting .
