3/4 cups (or 1 1/2 sticks) of unsalted butter, softened
2 1/4 cups of sugar
3 large eggs, room temperature
6 tablespoons red food coloring
3 tablespoons cocoa powder (unsweetened)
2 teaspoons vanilla extract
1 teaspoon sea salt
1 1/2 cups of buttermilk (use the homemade buttermilk recipe here!)
3 1/3 cups of flour (all-purposed, cake flour)
1 1/2 teaspoon apple cider vinegar
1 1/2 teaspoon baking soda
Preheat the oven to 350 degrees F. Grease a cake pan, preferably 3 round cake pans, or one sheet cake pan.
In a large bowl, cream butter and sugar with an electronic mixer until fluffy. Then add one egg at a time and beat well.
In a small bowl, whisk together food coloring, cocoa, and vanilla. Add to butter mixture and beat well.
In a measuring cup or another small bowl, stir salt into buttermilk. Alternate adding in flour and buttermilk while mixing together after each pour-in.
Once combined and beginning to create a cake batter texture, add in apple cider vinegar and baking soda. Mix well.
