Chocolate Cake with Fudge Frosting instructions

1. Preheat oven to 350 C. Grease & line two 8-inch round baking pans with parchment paper. Grease parchment..
2. For the Cake - In a large mixing bowl, combine the sugar, flour, cocoa, baking soda, baking powder & salt, whisking until thoroughly combined. Next, in a separate bowl Crack eggs, add buttermilk, oil & vanilla. Lightly mix with fork then pour this wet mixture into the dry ingredients. Whisk to mix then add in hot boiling water, keep whisking or Beating with an electric mixer on medium speed until all ingredients are incorporated. Divide evenly among prepared pans..
3. Bake for 40-45mins (30-35mins for a 6-inch cake) or until a toothpick inserted in the center comes out with just few moist crumbs attached. Remove from oven to cool. Run a small knife around the edges of each pan, then gently invert onto wire racks. Cakes should come out cleanly..
4. Peel off the parchment paper & allow cakes to cool completely. At this point, cakes can be frozen until ready to use, up to 1 month. Simply wrap each layer individually in a double layer of plastic wrap & store inside a large zip top bag..
5. For the frosting - in a bowl of a stand mixer fitted with paddle attachment, beat butter on medium speed until very pale & creamy, abt 5mins. Add sifted powdered sugar & cocoa powder & mix to combine. Add sour cream, hot water, vanilla & salt & mix on low speed until the liquid is incorporated, scraping down the sides of bowl as needed. It may look slightly curdled at this point, but dont worry. Increase speed to medium high & beat until smooth for another 2-3mins..
6. Add lukewarm chocolate & mix until smooth & glossy. At this point, you hv abt 30mins at cool room temperature (longer in summer) to work with the frosting before it begins to harden. Note: this frosting does not do well when made a head of time..
7. To assemble - level cake layers if necessary (trim any domed top off with serrated knife). Place one layer, bottom side up, on a cake stand or serving platter (on a piece of parchment if you will need to move it). Spread abt 1 cup of frosting in an even layer, then place second layer on top, flat side up, pressing gently to adhere..
8. Cover the entire cake with a thin layer of buttercream using offset spatula. This ‘crumb coat’ will seal in the cake crumbs & make the final layer of frosting easier. If your cakes were frozen, this should firm up pretty quickly, otherwise refrigerate for abt 10mins to set. Slather with remaining buttercream in a thick layer, reserving some for piping decorative details if desired..
