Instructions

 

Naturally Red Velvet Cake:

 

  1. Preheat oven to 425 degrees. Wrap beet in foil and roast until tender, about 1 hour. Reduce heat to 375 degrees for baking cake once beet is cooked. Butter three 9-inch cake rounds. Dust with flour and tap out the excess.
  2. Remove roasted beet from foil. The skin should easily slide off the beet. Discard skin and place beet into a large mixing bowl. Use a hand mixer to whip the beet into mush. 
  3. Add eggs, buttermilk, warm water, oil, vanilla, and vinegar and beat until combined, about 1 minute. Add in flour, sugar, cornstarch, cocoa, baking soda, baking powder, and salt in a stand mixer using a low speed until the mixture is smooth.
  4. Divide batter among the three prepared pans. Bake for 30-35 minutes until the cake meets the toothpick test (stick a toothpick in and it comes out clean).
  5. Cool on wire racks for 15 minutes and then turn out the cakes onto the racks and allow to cool completely before frosting.

 

Ermine Frosting:

 

  1. In a medium sauce pan, whisk together flour and sugar over low heat. Cook for 2 minutes. Slowly whisk in milk and bring to a boil. Cook until thickened into a pudding-like consistency, about 1 minute, and then remove from heat. Pour into a bowl and place plastic wrap directly on top of the mixture so no skin forms. Set aside. 
  2. In a large bowl, use a hand mixer to whip butter until light and fluffy, about 2 minutes. Add in cooked milk mixture 1 to 2 tablespoons at a time, mixing well between each addition. Once all milk mixture has been added in, beat in vanilla and salt and continue beating until the frosting is thick and creamy and everything is well mixed in.  
  3. Assemble and frost the completely cooled cake.
