Ingredients
– 2 large eggs, room temperature and separated
– 1 and 1/3 cups (166g) all-purpose flour
– 1/4 cup (32g) cornstarch
– 1/2 teaspoon baking soda
– 4 teaspoons (7g) natural unsweetened cocoa powder
– 1/4 teaspoon salt
– 1/4 cup (4 tablespoons; 56g) unsalted butter
– 1 cup (200g) granulated sugar
– 1/2 cup (120ml) canola or vegetable oil
– 2 teaspoons pure vanilla extract
– 1/2 teaspoon distilled white vinegar
– About 2 tablespoons liquid or gel red food coloring for deep red color
– 1/2 cup (120ml) buttermilk, room temperature
Instructions
1-Preheat the oven: Preheat the oven to 350°F (177°C) and line a standard muffin tin with cupcake liners. Bake in batches if you need more than the tin holds.
2-Beat the egg whites: Beat the egg whites with a whisk attachment until soft peaks form, then set them aside for later.
3-Whisk together dry ingredients: Whisk together the flour, cornstarch, baking soda, cocoa powder, and salt in a bowl to get everything evenly mixed.
4-Beat the butter and sugar: Beat the butter on high speed until it’s smooth and creamy, about 1 minute, then add sugar and beat for 2 more minutes, scraping the bowl as needed. Add oil and beat for another 2 minutes the mixture might look a bit separated, but that’s okay.
5-Add egg yolks and flavorings: Add the egg yolks and vanilla extract; beat until combined. Stir in the vinegar and red food coloring until you get that deep red shade you want.
6-Combine dry ingredients and buttermilk: On low speed, add the dry ingredients and buttermilk alternately in three additions, starting and ending with the dry ones. Mix just until everything is incorporated to keep the batter light.
7-Fold in egg whites: Gently fold the whipped egg whites into the batter using a spatula; it’ll turn silky and a tad thick at this point.
8-Fill liners and bake: Fill the cupcake liners halfway to two-thirds full and bake for 20-21 minutes, or until the tops bounce back when touched and a toothpick comes out clean.
9-Cool the cupcakes: Cool the cupcakes in the pan for 5 minutes, then move them to a wire rack to cool completely.
10-Frost cupcakes: Frost the cooled cupcakes with cream cheese frosting just before serving for the best taste and texture.
