Instructions
Blue Velvet Cake Layers

1. Preheat
   oven to 350°F. Line three eight-inch pans or three eight-inch round
   pans with parchment rounds, and lightly spray with non-stick cooking
   spray.
2. Mix together all dry ingredients (flour, baking powder,
   sugar, and salt) in a stand mixer with a paddle attachment until fully
   combined.
3. Mix chunks of room-temperature butter slowly into the
   dry mix, on a low speed. Continue to mix until no large chunks of butter
   remain, and the mixture looks crumbly.
4. On a low speed, mix in
   eggs one at a time. Beat on low until just incorporated. Mix in the
   buttermilk in two installments, on a low speed. Add in vinegar, vanilla
   and oil, and mix at a low speed until fully incorporated. Scrape down
   the sides of the bowl with a spatula, then beat on medium speed for
   about 30 seconds.
5. Divide the batter evenly between three bowls,
   and use increasing amounts of blue gel food coloring to create ombre
   blue cake layers.
6. Evenly divide the batter between the prepared cake pans. Bake for 35-37 minutes (or until a skewer comes out clean).
7. Allow
   to cool for 10 minutes, then run an offset spatula around the pan to
   separate the cake from the pan. Place cake layers into the freezer for
   45 minutes, to accelerate the cooling process.
8. Once the layers have fully cooled, I like to trim the caramelized bits from the sides of the layers using a serrated
   knife. While these layers bake pretty flat, sometimes I’ll also trim
   the top of the layers too, to get my layers perfectly level.
9. Next, torte the layers but cutting each layer in half horizontally.

Vanilla Frosting

1. Beat
   the butter on a medium speed for 30 seconds with a paddle attachment,
   until smooth. Slowly add in the powdered sugar, 1 cup at a time.
   Alternate with small splashes of cream.
2. Once fully mixed, add in
   the vanilla and salt, and beat on low until the ingredients are fully
   incorporated, and the desired consistency is reached.
3. If the
   frosting is too thick, add in additional cream (1 teaspoon at a time).
   If the frosting is too thin, add in more powdered sugar (quarter of a
   cup at a time).

Cake Assembly

1. Frost and assemble the cake, spreading a thin layer of frosting between each cake layer.
2. Crumb
   coat the cake, and chill in the freezer for 5 minutes. When the crumb
   coat is firm to the touch, add and smooth a second, thicker layer of
   frosting.
3. Chill the cake in the freezer for 20 minutes, then
   lightly dab a mixture of vodka (or lemon extract) and sky blue gel food
   coloring onto the side of the cake using a small sterile sponge.
4. Place
   the cake back in the fridge for 10 minutes. In a small bowl, mix
   together 1/2 cup of leftover frosting with and one extra Tbsp of heavy
   cream. Carefully secure the template to the side of the cake using
   toothpicks.
5. Spread a thin layer of frosting over the template
   using an offset spatula. Remove one toothpick, and slowly peel the
   template off the cake. Repeat pattern on the other half of the cake.
6. Color any remaining frosting blue, and pipe swirls onto the top of the cake.
