3ozunsalted butter, softenend(84 grams)
2 cupspowdered sugar(8 oz/225 grams)
1teaspoonvanilla extract
1teaspoonlemon juice
Instructions
Cook the beets ahead of time. Cut the beets in half, boil until tender, then let cool and peel. Puree the cooked beets, then put the puree through a strainer and drain as much excess juice out as you can. You may have more, but for the cake you'll need 5 oz/140 grams of cooked beets. Stir the lemon juice and zest into the cooked beets.
Preheat oven to 350 degrees F. Grease and flour three 6-inch round cake pans or two 8-inch round pans.
Whisk together flour, sugar, cocoa, baking powder, baking soda and salt and set aside.
Put the eggs in the bowl of a stand mixer and begin beating with the whisk or paddle. Drizzle in the oil and beat until thick and lemon colored (about a minute). On low speed, beat in the pureed beets, vanilla, and buttermilk.
Add the flour mixture and stir by hand until blended, then beat on low for about a minute or until smooth and evenly blended.
Divide the batter between three greased and floured 6-inch cake pans (a little over 9 oz per pan). Bake at 350 degrees F. for about 22-25 minutes. The cakes should puff up a little. If baking in 8-inch pans, check at 20 minutes.
Let cool for 10 minutes in the pan, then loosen and invert onto a cooling rack.
When cake is cool, beat softened cream cheese and butter in the bowl of a stand mixer fitted with the whisk attachment or paddle. Gradually add powdered sugar, beating on low speed until blended and scraping bowl often and light and fluffy. Beat in vanilla and lemon juice.
Frost the cake and keep refrigerated until ready to serve.
Notes
I mostly use olive oil, but when I need a neutral oil Wesson oil seems to be the best (in my opinion). It also seems to stay fresher longer than canola.
