Directions

1. Preheat to 350 degrees Generously grease two, 9- x 2-inch pans with non-stick spray or shortening.In a medium size bowl, after measuring, sift together the flour, cocoa powder, baking powder, baking soda, powdered buttermilk and salt. Stir together with a spoon. Set aside.
2. Mix the water with the food coloring and vanilla extract. Set aside.Using a stand mixer with a paddle attachment, beat the butter on low speed until soft. (If the butter is cold, it will warm quickly from the beaters - taking about 60 seconds).Slowly add sugar in a steady stream at the side of the bowl. Increase speed to medium and beat for 2 minutes until light yellow and fluffy. Stop the mixer and scrape the side and bottom of the bowl with a large rubber spatula.With the mixer on low, add the eggs one at a time and beat for 20 seconds after each addition. Increase the mixer speed to medium and beat the mixture for 2 minutes. be sure to use a kitchen timer to help you keep track of the time. The mixture will become fluffy and aerated.
3. Add the flour mixture in 3 equal portions, alternating with the water in 2 equal portions, beginning and ending with the flour. (If the milk is cold, the batter will curdle slightly. It's ok. It will come together when you add the flour.)
4. Mix on low and work quickly so you don't over mix.After completing the last addition of flour, stop the mixer, and scrape the side and bottom of the bowl with a large rubber spatula.Then, let the mixer run for 30 seconds on LOW. The batter will be thick and fluffy. STOP the mixer. Do NOT overmix.With a large rubber spatula, give the batter ONE or TWO quick folds to incorporate any stray flour or liquid left at the sides and bottom of the bowl. do not continue mixing!Divide the batter equally into the prepared pans and lightly smooth their tops. The pans should be about 1/2-full.(I use my kitchen scale to be sure both pans are equal)
5. Bake the cake layers for 20 to 30 minutes or until the top feels firm and gives slightly when touched. (inserted a toothpick in the middle should have a few moist crumbs attached, but not batter.)Loosen the sides with a small metal spatula or sharp knife. Invert onto cake rack and place upright to cool completely.In a mixing bowl, blend butter and shortening until smooth.
6. Add a pinch of salt, vanilla and cinnamon. Continue mixing until well blended. Gradually add powdered sugar 1 cup at a time, beating well after each addition. Eventually you will have a very thick gooey mixture. On the highest speed of your mixer, stream in the heavy whipping cream- pour nice and slow.Continue beating on high speed until frosting is fluffy
7. Place butter in a large mixing bowl and blend slightly.
8. Add cream cheese and blend until combined, about 30 seconds.
9. Add vanilla and sugar and blend on low until combined. Increase to medium speed and beat until it begins to get fluffy. Slowly add the cream a little at a time until desired consistency is met. (you want it thick enough to hold it's shape if you are going to pipe on roses)I added some bright white gel coloring at this point to make my frosting nice and white.Beat until fluffy, about 1 minute. Using a long serrated knife, slice both cooled cake layers in half horizontally, yielding 4 cake layers (you can leave your cake as 2 thicker layers with one layer of filling if you'd prefer).Top each cake layers with about 1 cup of cinnamon buttercream.Frost outside of cake with Vanilla Cream Cheese Frosting.You can go to iambaker.net to follow her rose cake tutorial
