Ingredients

Scale

Ermine Frosting

  • 1 1/2 cups granulated sugar
  • 1/2 cup all-purpose flour
  • 1 teaspoon salt
  • 2 cups whole milk
  • 2 cups unsalted butter (room temperature)
  • 1 tablespoon vanilla extract

Cake

  • 3 cups cake flour
  • 3 tablespoons natural cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter (room temperature)
  • 2 cups granulated sugar
  • 4 large eggs (room temperature)
  • 1 tablespoon vanilla extract
  • 1/2 cup vegetable oil
  • 1 cup buttermilk (room temperature)
  • 2 teaspoons apple cider vinegar (or white vinegar)
  • 4 teaspoons red gel food coloring

Instructions

  1. Make the ermine frosting base: In a medium saucepan over medium heat, whisk together sugar, flour, and salt. Gradually whisk in the milk until smooth. Cook the mixture, whisking frequently, for 5-7 minutes until it thickens to the consistency of sweetened condensed milk. Remove from heat.
  2. Cool the frosting base: Transfer the mixture to a bowl. Press plastic wrap directly onto the surface to prevent a skin from forming. Allow it to cool completely at room temperature for about an hour. To speed up, refrigerate but do not let it get cold enough to solidify.
  3. Prepare the frosting: Once cooled, beat the room temperature butter in a large bowl with a hand or stand mixer until light and fluffy (2-3 minutes). Add the cooled flour mixture gradually, about 1 tablespoon at a time, beating well after each addition until smooth. Add vanilla extract and beat until the frosting is silky and whipped in texture. Do not add the flour mixture if it is still warm.
  4. Prep the cake pan and oven: Preheat the oven to 350°F. Generously grease a 9×13 inch or 13×18 inch baking pan and set aside.
  5. Mix the dry cake ingredients: In a bowl, whisk together cake flour, cocoa powder, baking soda, and salt to combine and aerate. Set aside.
  6. Create the wet cake batter base: In a large bowl, beat the room temperature butter and granulated sugar until creamy and smooth. Add vanilla extract and eggs, continuing to beat until the mixture is creamy and evenly combined.
  7. Combine wet ingredients: In a separate bowl, whisk together vegetable oil, buttermilk, vinegar, and red gel food coloring.
  8. Mix the batter: Add half of the dry ingredient mixture to the butter and egg mixture, stirring just to combine. Then add half the buttermilk mixture, stirring again until just incorporated. Repeat this process with the remaining dry and wet ingredients, taking care not to overmix the batter.
  9. Bake the cake: Pour the batter evenly into the prepared pan and spread to smooth. Bake 32-38 minutes for a 9×13 inch pan, or 18-20 minutes for a 13×18 inch half sheet pan. Check doneness visually: the cake should spring back when pressed lightly in the center, and an instant-read thermometer should register approximately 210°F.
  10. Cool the cake: Remove the cake from the oven and cool completely in the pan on a wire rack before frosting.
  11. Frost and serve: Spread the prepared ermine frosting evenly over the cooled cake. Slice into squares and serve.

Notes

  • Allow all refrigerated ingredients, especially eggs, butter, and buttermilk, to come to room temperature for better batter consistency.
  • Do not add warm flour mixture to the frosting butter as it may melt and ruin the texture.
  • Use gel food coloring for richer, more vibrant red color without thinning the batter.
  • Do not overmix the cake batter to keep it tender and airy.
  • Check the cake a few minutes before the minimum baking time as ovens vary.
  • Ermine frosting is less sweet and lighter than cream cheese frosting, offering a unique, silky texture.
