The secret ingredient in this sweet dessert is — you guessed it — beets!
3 medium beets
3/4 cup butter, plus more for greasing pan
3/4 cup buttermilk
Juice of 1 large lemon
2 teaspoon white vinegar
1 1/2 teaspoon vanilla extract
2 cups Nash’s soft white flour*
3 tablespoons cocoa powder
1 1/8 teaspoon baking powder
1 teaspoon salt
1/2 teaspoon baking soda
1 3/4 cup sugar
3 eggs
Heat oven to 350 degrees F. Wash beets and wrap in aluminum foil. Bake until the tip of a knife slides easily into the largest beet, about 1 hour 15 minutes. Cool until beets can be handled, then peel. (This may be done up to a day ahead.)
Butter two 9-inch cake pans. Line the bottoms of the pans with parchment and then butter again.
In a food processor, chop beets to pieces about the size of finely diced onions. Measure 1 cup and set aside (remaining beets can be reserved for another purpose). Return cup of beets to the food processor. Purée with buttermilk, lemon juice, vinegar and vanilla until smooth.
Sift together flour, cocoa, baking powder, salt and baking soda. Set aside. In the bowl of a stand mixer, beat butter until soft. Slowly add sugar and beat until creamy. Beat in eggs one at a time, scraping down the sides of the bowl after each addition.
Alternate adding flour mixture and beet mixture to butter mixture, beginning and ending with the dry ingredients, and beating for 10 seconds after each addition. Scrape down the bowl after each addition of the wet ingredients.
Divide batter between prepared cake pans, smoothing the tops. Bake until a cake tester inserted in the cake comes out clean, about 20 minutes. Remove pans from oven and cool completely on a wire rack. Frost with cream cheese frosting or other white icing.
*Nash’s soft white wheat flour has been milled fine, but if you want your Red Velvet Cake to be really silky, sift it before measuring it. We usually don’t, so we can get all the health benefits from the germ and bran.
