Miscellaneous

  • Crushed Candy Canes for topping

Instructions

For the Chocolate Peppermint Cake Layers

  • Preheat oven to 325 degrees. Grease and flour three 8 inch pans. I also like to line my pans with circles of parchment or waxed paper.
  • This recipe uses the Reverse Creaming Method of Mixing.
  • Add dry ingredients to the bowl of your mixer and mix for one minute to blend (sugar, flour, cocoa, baking soda, baking powder, and salt)
  • Add butter a few slices at a time and mix until it reaches a crumbly, sandy texture. Be careful not to over-mix beyond "sandy" consistency.
  • In another bowl, combine sour cream, eggs, milk, and vanilla, and peppermint extract. Using a fork, mix together. This is all of your wet ingredients except for the coffee, it will be added to the batter later.
  • Set a timer for 1 ½ minutes and SLOWLY add half of your egg mixture to your butter/flour mixture while mixing. Start mixer on low speed then increase to medium for the remainder of the 1 ½ minutes. Do Not Mix Above Medium Speed.
  • Stop mixer, scrape the sides and bottom of bowl, and add half of the remaining egg mixture. Mix on medium speed for 20 seconds.
  • Stop mixer, scrape down the sides if necessary, and add the last of the egg mixture. Mix for 20 more seconds on medium speed.
  • Slowly add HOT coffee and mixing for 30 seconds to blend. Batter will be runny but that is okay!
  • This recipe makes about 9 ½ cups of batter.Pour into 3 prepared 8 inch pans and bake at 325 degrees for 25 to 30 minutes or until the center of the cake springs back to the touch and a toothpick comes out clean.

For the Coffee Simple Syrup

  • In a small saucepan add the sugar and water. Bring to a boil and remove from the heat. Stir until sugar dissolves.
  • Let this cool before brushing onto the cake. You can store leftover syrup in the refrigerator for 2 weeks. Do not put too much on the cake layers or they will become soggy.
  • If you'd like to you can use a fork or toothpick to make holes in the top of the cake layers before brushing (preferably with a pastry brush) the simple syrup onto each layer.

For the Mocha Buttercream Frosting

  • Mix the instant coffee granules into the ¼ cup of hot water to dissolve, set aside to cool slightly.
  • Beat the butter on medium speed until smooth. Blend in the vanilla and cocoa powder and salt.
  • Add half of the powdered sugar and half of the coffee. Beat at medium speed until the powdered sugar is incorporated.
  • Add the remaining powdered sugar and coffee and mix at medium speed another 3 to 6 minutes scraping the sides of the bowl occasionally.
  • This recipe makes 6 cups of frosting.
  • If your consistency is too thin, add more powdered sugar. If too thick, add a bit more water or milk, a teaspoon at a time.

For the Peppermint Whipped Cream Cheese Filling

  • Chill the whisk attachment or beaters of a handheld mixer in the freezer for about 10 minutes.
  • In a medium sized bowl, add the cream cheese, powdered sugar, and peppermint extract. Mix until blended. Slowly add the heavy cream and beat until fluffy- it may take 2 minutes.
  • This is a soft filling and so you'll want to pipe a dam of frosting about ½ inch from the edge of the cake layers, then spread filling within the dam. Makes about 3 cups.

Assembly of Cake

  • Place first cake layer on cake base or pedestal.
  • Using a pastry brush, lightly brush the coffee simple syrup over the top.
  • Pipe a dam/ring of mocha buttercream about ¼ inch to ½ inch from the edge of the cake layer. Fill with Whipped Peppermint Cream Cheese Filling.
  • **If you would like to settle the cake (as explained in the post), wrap the tier with plastic wrap, place a "weight" on top (cake pan, book, etc.) to give a light, steady pressure. Sit for a few hours or overnight. Remember the filling is perishable and so refrigerate as needed.
  • Frost the cake with the Mocha Buttercream Frosting. Top it off with the remaining Whipped Peppermint Cream Cheese. (I used a 6B piping tip to cover the top of the cake)
  • As a final touch, I used Ghirardelli Dark Chocolate Chips around the border, I used a tip 21 to add a shell border around the bottom of the cake, and sprinkled crushed candy canes over the top.
