- Vanilla Extract: Vanilla extract enhances flavor.

- Baking Powder & Baking Soda: Both of these leavening agents work together to create the gorgeous dome shape and airy texture.
- Salt: Salt enhances sweetness!
Step by Step Process
STEP 1: Preheat your oven to 350 degrees Fahrenheit and line a mini muffin tray with liners.


STEP 2: In a large bowl, granulated sugar, a room temperature egg, vegetable oil, room temperature buttermilk, and vanilla extract together until smooth.
STEP 3: Next, add properly-measured all purpose flour, baking powder, baking soda, and salt together only until you see the dry ingredients disappear into the batter. Do not mix past when you see the ingredients combine to avoid dense cupcakes.


STEP 4: Then, divide the batter between the liners, adding about 1 ½ tablespoons of batter to each liner.
STEP 5: Bake the cupcakes for 9-11 minutes or until the tops are light pale in color, shiny, and spring back when poked with your pointer finger. A toothpick inserted into the center should come out with some moist crumbs.

- Measuring Flour: Measure flour correctly by using a kitchen scale to measure 210g exactly. If you don’t have a scale, spoon the flour into your measuring cups before using a knife to level off the top. Overmeasuring flour will lead to dry cupcakes.

Ingredients
For the Cupcakes
- ¾ cup (158g) granulated sugar
- 1 large egg, room temperature
- ⅓ cup (66g) vegetable oil
- 1 ¼ cup (300g) buttermilk, room temperature
- 1 teaspoon vanilla extract
- 1 ½ cups (210g) all purpose flour

- ½ teaspoon baking soda
- ½ teaspoon salt

- 1 cup (220g) unsalted butter, room temperature
- 2 ½ cups (300g) powdered sugar
- 2 tablespoons (30g) milk

- Add milk to the frosting and beat on high speed for about 3-5 minutes. This will create air in the frosting, resulting in a smooth, bright, white, and fluffy frosting. Transfer the frosting to a piping bag or zippable plastic bag with the corner snipped off for greater control if desired.
