This rich and delicious chocolate frosted cake is everything you want in a cake. The cake is rich in butter and the chocolate is everything in this cake. Add room temperature butter to the bowl of a stand mixer along with granulated sugar and mix on high speed for about 4 minutes until pale and fluffy. Slowly add vegetable oil until it is thoroughly mixed in and also add 5 eggs one by one until incorporated before adding the other.
Once the eggs are mixed in, add sour cream and continue to mix for about 3 minutes. Sift in all-purpose flour, baking powder and baking soda then mix on medium to high speed and mix for an additional 3 to 4 minutes until the batter becomes silky smooth then pour the batter into a round or rectangle pan and bake the cake for 30 minutes at 350 degrees Fahrenheit.
For the chocolate buttercream, add room temperature butter in the bowl of a stand mixer and whip for 3 minutes then add cocoa powder and vanilla extract and mix on high speed for about 7 minutes making sure to gradually add in powdered sugar and mix thoroughly making sure you scrape the sides and bottom of the bowl.
Once the cake is well baked, allow it to cool down for about 5 minutes then place it on a cooling rack to cool completely. To frost, the cake, add a dollop of the chocolate buttercream and spread it evenly over the top of the cake then serve. This cake is my favourite for a birthday cake, the crumb is beautiful nice and fluffy the chocolate frosting is amazing. Sprinkle confetti on top for a birthday cake or you can serve it plain and enjoy.
