Not over the top in my book - just good! I make a similar one:
Dark Chocolate Cake from Scratch• 5 oz. dark chocolate, chopped• 1 1/2 cups strong coffee• 3 cups sugar• 2 1/2 cups flour• 1 1/2 cups Hershey's Dark Cocoa Powder• 2 tsp. baking soda• 3/4 tsp. baking powder• 1/2 tsp. salt• 3 large whole eggs and 1 large egg yolk• 3/4 cup vegetable or canola oil• 1 1/2 cups buttermilk• 1 tsp. vanilla
(I skip the baking soda and use more baking powder. I think I'm a super taster when it comes to baking soda and I can't stand it LOL).
