High Altitude Yellow Cupcakes
- Preheat the oven to 375°F. Line two cupcake pans with paper cupcake wrappers.
- In a small bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt. Set aside.
- In a large bowl, beat the butter and sugar together until the mixture is pale yellow and fluffy, about 3-4 minutes. Add the eggs one at a time until incorporated. Then, mix in the vanilla extract and sour cream. Scrape down the sides of the bowl.
- Stir in half of the flour mixture followed by half of the milk. Repeat with the remaining flour mix and milk, stirring just until combined. Don't overmix!
- Divide the batter evenly between the 24 cupcake wrappers, until the cups are about 2/3 full each. Bake the cupcakes for 12-14 minutes, just until an inserted toothpick has a few moist crumbs.
- Let the cupcakes cool in the pan for a few minutes. Transfer the cupcakes to a cooling rack and allow them to cool completely before frosting.
Chocolate Buttercream
- In a large bowl, beat the butter for a couple of minutes until it is fluffy. Add the cocoa powder and mix until combined.
- Next, add the powdered sugar 1 cup at a time until the frosting comes together. Then, add the whole milk or heavy cream 1 Tablespoon at a time until the frosting is smooth and reaches your desired texture.
- Whip the buttercream for 5-6 minutes until it is light and fluffy. Pipe the buttercream onto the cooled cupcakes with a piping bag and tip. Or, use a butter knife or offset spatula to spread the frosting onto the cupcakes. Decorate as desired. Enjoy!
