Step 1

Preheat oven to 350 degrees Fahrenheit. In a medium sized bowl, mix together the flour, cocoa powered, salt, baking soda and baking powder. In a large bowl, cream together the butter and sugars. Add the eggs one at a time and then add the vanilla and mix again. Finally add the milk and mix one last time. The wet mixture might look a little strange at this point, but that is ok!

Step 2

Add the flour mixture and the Greek yogurt to the wet mixture, one half at a time alternating between the two, starting with the flour. Give the batter one last mix until everything is combined.

Step 3

Grease three 8 inch cake pans and equally distribute the batter into the pans. Bake cakes for about 30 minutes or until an inserted toothpick comes out clean. Let the cake cool inside the pan for ten minutes and then transfer to a cooling rack.

Step 4

Once the cakes are cooled, transfer to a plate or cake stand and stack the cakes on top of eachother, frosting in between each one. Frost the top and sides of the cake, smoothing out with a knife if necessary.
