How To Make

Prepare the Pan

Preheat your oven to 175 degrees Celsius or 350 degrees Fahrenheit for your Old Fashioned Chocolate Cake. Make sure the oven is fully preheated before baking.

Grease and flour a 9 by 13 by 2 inch baking pan. This prevents sticking and makes removal easy.

Remove from heat and set aside to cool slightly. Don’t let it get completely cold.

Combine Wet Ingredients

In a separate bowl, dissolve the baking soda in the buttermilk, Stir in the lightly beaten eggs and vanilla extract.

Add the cooled cocoa mixture and mix until well combined for your Old Fashioned Chocolate Cake. The mixture should be smooth.

Make the Batter

In a large mixing bowl, whisk together the flour, sugar, cinnamon, and salt for your Old Fashioned Chocolate Cake. Make a well in the center.

Pour in the cocoa mixture and stir just until combined. Do not overmix. The batter will be thin and this is completely correct.

Bake the Cake

Bake for 30 minutes until a toothpick inserted in the center comes out clean for your Old Fashioned Chocolate Cake. The top should look set.

Make the Icing

When the cake is about halfway through baking, start the icing for your Old Fashioned Chocolate Cake. In a large saucepan over medium heat, melt the butter with the sifted cocoa powder.

If lumps remain, beat briefly with a handheld electric mixer for your Old Fashioned Chocolate Cake. Work quickly to get smooth texture.

Apply the Icing
