Ingredients & Directions
- Vanilla Cupcakes
Directions
Preheat the oven to 350°F and line 2 cupcake pans with a total of 15 liners, spreading them out in the pan.
In the bowl of a stand mixer, whisk together the flour, cornstarch, sugar, baking powder, baking soda, and salt.
Cube the butter, then add it and the vegetable oil to the dry ingredients and mix using the paddle attachment on medium speed. Stop once the mixture resembles wet sand.
In a separate bowl or large liquid measuring cup, whisk the water and sour cream until smooth. Then, add the vinegar, eggs, egg yolk, and vanilla extract and whisk until smooth.
With the mixer running on low speed, slowly stream in the sour cream mixture until combined.
Do a final mix by hand to ensure the batter is mixed evenly.
Fill the cupcake liners half full, then bake at 350 for 15-16 minutes, or until a toothpick comes out mostly clean with a few moist crumbs attached. Let the cupcakes cool completely.

To ensure food safety, eggs should be cooked until both the yolk and the white are firm. Consuming raw or undercooked eggs may increase your risk of foodborne illness, especially for those with certain medical conditions. For recipes that call for eggs that are raw or undercooked when the dish is served, use either pasteurized shell eggs that have been treated to destroy Salmonella, or use pasteurized egg products.
