Ingredients

Scale
  • 1 box red velvet cake mix (preferably Betty Crocker Delights or Duncan Hines)
  • 5 ounces all-purpose flour (1 cup spooned in and leveled)
  • 7 ounces granulated sugar (1 cup)
  • 6 ounces sour cream, room temperature or plain Greek yogurt (¾ cup)
  • 2 tablespoons cocoa powder
  • ½ teaspoon salt
  • ½ teaspoon baking soda
  • 1 teaspoon vanilla extract
  • 2 ounces vegetable oil (¼ cup)
  • 4 ounces unsalted butter, melted (½ cup)
  • 12 ounces buttermilk, room temperature (or regular milk + 1 tablespoon of white vinegar, 1 ½ cups)
  • 3 large eggs (room temperature)
  • 1 tablespoon Super Red Food Coloring
  • For Easy Swiss Meringue Buttercream:
  • 6 ounces pasteurized egg whites
  • 24 ounces sifted powdered sugar
  • 2 teaspoons vanilla extract
  • ½ teaspoon salt
  • 24 ounces unsalted butter (room temperature)
  • ⅛ teaspoon yellow food coloring
  • 1 teaspoon electric pink food coloring
  • 2 tablespoons super red food coloring

Instructions

  1. Preheat oven to 335℉ and prepare three 8″ round cake pans, preferably with cake goop.
  2. Add all ingredients for the cake into the bowl of a stand mixer with the paddle attachment and mix on low for 2 minutes to combine.
  3. Stop to scrape the bowl and then mix on medium for 2 minutes.
  4. Pour batter into prepared cake pans and bake for 25-30 minutes until a toothpick comes out with a few sticky crumbs.
  5. Test the cake’s doneness by gently touching the top; if it does not bounce back, bake for an additional minute.
  6. Let the cakes cool for a few minutes in the pans before transferring them to a cooling rack to cool completely before frosting.
  7. For the Easy Swiss Meringue Buttercream, combine egg whites and powdered sugar in a stand mixer bowl, mix on low, then whip on high for 1 minute.
  8. Add salt and vanilla extract to the egg mixture.
  9. In chunks, add unsalted butter and whip until well combined; it may look curdled initially.
  10. If the buttercream looks curdled, melt about ⅓ cup of it in the microwave for 10-15 seconds, then pour it back into the mixing bowl to bring it all together.
  11. Switch to the paddle attachment, mix on low for 15-20 minutes for a very smooth consistency and to remove air bubbles.

Notes

  • Room temperature ingredients help create a better texture in the cake.
  • Ensure butter and eggs are at room temperature for the buttercream to incorporate better.
  • For a more intense red color, add more Super Red Food Coloring if desired.
