Preheat the oven to 350℉. Line a 12 cup cupcake pan with cupcake liners. Set aside.
In a medium bow, sift together flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
1 1/2 cups All-purpose flour, 2 TBSP Unsweetened cocoa powder, 1 tsp Baking powder, 1/4 tsp Baking soda, 1/2 tsp Salt
Using a mixer in a large bowl, beat the butter, oil, and sugar on high speed for 2 minutes. It will become pale in color.
1/4 cup Unsalted butter, 1/4 cup Oil, 1 cup White granulated sugar
Add in the vanilla, vinegar, sour cream, eggs, and red food dye. Mix on medium until combined.
1 tsp Pure vanilla extract, 1 tsp White vinegar, 1/4 cup Sour cream, 2 Large eggs, 1 tsp Red gel food dye
Add in the dry ingredients and buttermilk and mix on low until just combined. Take off the mixer and use a baking rubber spatula to stir the batter.
1/2 cup Buttermilk
Use a large cookie scoop to scoop the batter into the cupcake liners. Fill it 2/3rds full.
Bake for 17-19 minutes. Bake until a toothpick inserted comes out clean.
Let the cupcakes sit in the hot pan for 10 minutes. Then, transfer to a cooling rack. Cool completely before decorating.
