Key ingredients
This section reviews the best ingredients and substitutions for this recipe. For an exact list of ingredients and quantities, check the recipe card below.
- Buttermilk - Use regular buttermilk, not a low-fat version. If you don't have buttermilk on hand, place 1 tablespoon of white distilled vinegar or 1 tablespoon of fresh lemon juice into a glass measuring cup. Add milk until it reaches the one cup measure. Stir and let rest for 10 minutes, then use. Check out the complete directions and all about making homemade buttermilk.
- Unsweetened Cocoa Powder - I use regular cocoa powder, not dutch process
- Flour - Use all-purpose flour
- Sugar - Two types of sugars are used in this recipe. Granulated sugar is used in the cake and powdered sugar in the icing.
- Oil - Use a light-tasting oil like vegetable oil or canola oil
- Leaveners - Both baking soda and baking powder are used
Step by step directions
In this section, I share step-by-step photos, cooking methods, techniques, and a general overview. For detailed instructions, temperatures, and timing, check the printable recipe card below.
Cake
- Combine flour, sugar, cocoa powder, baking soda, baking powder, and salt in a bowl.
- Add buttermilk, oil, eggs, and vanilla. Mix until combined
- Stir in boiling water and stir until well incorporated
- Add immediately into a greased 9x13-inch cake pan and put into a preheated oven.
- Bake for 35-40 minutes until the cake is cooked through
- Remove from oven and allow the cake to cool in the pan
Icing
- Melt butter in a saucepan over medium-low heat
- Turn off the heat and whisk in cocoa powder
- Add buttermilk, vanilla, and powdered sugar
- Whisk until smooth. If small lumps of powdered sugar exist, just keep stirring until they disappear.
- While the cake is still warm, pour icing over the cake. Level the icing with a spatula and allow icing to fully cool and set up before slicing
Recipe tips
- The cake batter and icing can be completely mixed using a whisk
- As soon as you add the boiling water, mix thoroughly, and place directly into the cake pan and into the oven. The boiling water helps develop flavors with the cocoa powder but also activates the baking soda and powder and gives the cake the proper rise.
- Check to see if your cake is done by inserting a toothpick into the center of the cake. If it comes out clean, with no batter and just a few crumbs sticking to it, the cake is done. If there is batter, continue baking the cake for a few more minutes and test again.
- If using chocolate icing, add it while the cake is still warm. The icing will become slightly firm once cool and will have a crackly surface. If cutting the cake too soon, the icing will run off each slice.
- You may also use your favorite frosting. Allow cake to fully cool before frosting cake.
