This one bowl chocolate cake is super light and fluffy and is topped with a decadent chocolate buttercream. It is my favorite go to chocolate cake because it is just SO easy to make and has a rich chocolate flavor. It's the best cake for any occasion!
Preheat your oven to 350° F and spray a 9x13” or 3- 8” round pans with baking spray.
In the bowl of a stand mixer fitted with the paddle attachment, add the 3 cups sugar, 3 cups flour, 1 1/2 cups cocoa powder, 1 tbsp baking soda, 1 1/2 tsp baking powder, and 1/2 tsp kosher salt, and mix on low till combined.
Add the eggs one at a time, incorporating them into the mix before each addition.
Raise the speed up to medium and in a steady stream add in the 1 cup yogurt and 1 tbsp vanilla.
Mix until combined. Stop the mixer and scrape down the sides to make sure it is evenly mixed.
With the mixer running on medium again, add in the 1 1/2 cup coffee and 1/2 cup oil slowly.
Continue mixing until the batter is evenly mixed, it is a runny batter!
Pour into the prepared pan and bake for 40-45 mins for the 9x13 or 25-30 minutes for a 8" round. Or bake until the edges of the cake break away from the pan, or a skewer inserted in the middle comes out clean.
