Instructions
Preheat the oven to 350 deg F.
Line the cupcake liners in a muffin tray.
Combine and whisk all the dry ingredients in one bowl.
Using a stand mixer, beat the butter on high speed for 2 mins until smooth and creamy.
Add the sugar and beat on high for 3 mins until mixed well, keep scraping the batter from the sides into the bowl using a spatula.
Add the egg-whites and vanilla extract and vanilla beans(if using) and beat on medium until combined
.Add the sour cream and beat till combined.
Now at low speed, add the dry ingredients in two additions until just incorporated.
Finally, add the milk with the mixer running on low and do not over mix.
You can use a spatula or whisk and make sure it is mixed well with no lumps as the batter will be quite thick.
Pour the batter into the muffin tray with cupcake liner sheets two-thirds full.
Bake for about 19 to 22 minutes or until a toothpick inserted in the center comes out clean.
Cool cupcakes in the pan for 10 minutes and later on a cooling rack until cooled.
Frost it with buttercream , meringue or chocolate cream frosting and serve with sliced strawberries or ice cream!
Notes
Use room-temperature ingredients: Bring eggs, milk, and sour cream to room temperature before mixing. This helps the batter blend smoothly and ensures soft, evenly baked cupcakes.
Don’t overfill the liners: Fill cupcake liners only up to two-thirds full to allow proper rising and prevent overflow.
Bake on the middle rack: For even heat circulation and uniform baking, always place your cupcake tray on the middle rack of the oven.
Expect a thick batter: This batter is naturally thick, which helps create a soft, tender crumb and well-shaped cupcakes.
Easy cake flour substitute: If you don’t have cake flour, make your own by replacing 2 tablespoons of all-purpose flour with 2 tablespoons of cornstarch. Whisk well to combine and use as directed.
Use vanilla bean for extra flavor: While optional, adding vanilla bean seeds enhances the aroma and flavor, giving your cupcakes a beautiful bakery-style taste.
