Instructions
1Prepare the Cupcakes
15m
Preheat Oven
Preheat oven to 350°F (175°C). Line a muffin tin with 16 cupcake liners.
Combine Dry Ingredients
In a large bowl, whisk together the all-purpose flour, granulated sugar, baking soda, baking powder, and kosher salt.
Combine Wet Ingredients
In a separate bowl, whisk together the melted unsalted butter, egg whites, vanilla extract, sour cream, and warm whole milk until well combined. The mixture may appear slightly clumpy due to the butter.
Combine Wet and Dry
Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix; a few small lumps are acceptable.
Fill Liners
Distribute the batter evenly into the prepared cupcake liners, filling each about 2/3 full.
2Bake the Cupcakes
18m
Bake
Bake for approximately 18 minutes, or until the centers are springy to the touch and a toothpick inserted comes out clean.
Cool
Allow the cupcakes to cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely.
3Make the Buttercream Frosting
10m
Cream Butter
In a stand mixer fitted with a paddle attachment, cream the room temperature unsalted butter until smooth.
Add Sugar
Gradually add the sifted confectioners sugar in two batches, mixing until incorporated.
Add Flavorings
Add the vanilla extract, heavy cream, kosher salt, and whole milk. Mix on medium speed until the frosting is light and fluffy.
4Decorate the Cupcakes
2m
Transfer to Piping Bag
Transfer the buttercream frosting to a piping bag fitted with a star tip (such as an 849 tip).
Pipe Frosting
Pipe a generous dollop of buttercream onto each cooled cupcake.
Tips
Measure your flour correctly by using a kitchen scale or by spooning it into the cup and leveling with a knife to prevent dense cupcakes.
Ensure all wet ingredients for the cupcake batter are at room temperature for a smooth, emulsified batter.
Don't overmix the cupcake batter after combining wet and dry ingredients; a few lumps are okay.
Keep a close eye on the cupcakes towards the end of baking to prevent over-browning.
For best results, use good quality pure vanilla extract as it is the primary flavor.
