Ingredient notes and substitutions
- Plain all-purpose flour - you can use gluten-free flour (a blend with xanthan gum) instead. Substitute 1:1.
- Cocoa - I used unsweetened natural cocoa powder for this recipe. It's widely available in the US. On the other hand, in most parts of Europe, Dutch-processed cocoa powder is the common unsweetened cocoa powder widely available in stores. If you only get Dutch-processed cocoa powder, substitute the baking soda for 1 tablespoon (12g) baking powder. You can read more about the relationship between cocoa powder and leaving agents here. Please be aware that using Dutch-processed cocoa and baking powder will alter the taste and texture of the cake noticeably.
- Buttermilk - if you don't get buttermilk, you make your own. Therefore, pour 1 ½ teaspoon (7ml) of vinegar or lemon juice into a 1 cup (240ml) measurer and fill the cup with milk until full. Transfer to a jar, stir to combine and let sit for 5 minutes until the mixture starts to curdle a little. Then use in the recipe as directed.
- Pecans - are optional but highly recommended. You can use toasted pecans from the store or toast them on your own. If you would like to toast them, preheat the oven to 300°F (150°C). Spread the pecans on a baking sheet and bake for 7-8 minutes. Then remove from the oven and set aside.
Pan size
This recipe calls for a 9x13-inch (23x33cm) pan. The cake will be about ¾-inch (1.9cm) high. Alternatively, you can use a jelly roll pan 10 ½ x 15 ½ inch (27x39cm) and bake the cake for 14-17 minutes or until a toothpick inserted into the center of the cake comes out clean.
If you want to bake a smaller cake, divide the recipe in half and bake in a 9x9-inch (23x23cm) baking pan. The baking time is the same.

In a large mixing bowl, whisk flour, sugar, cocoa, baking powder, and salt to combine. Set aside.

In another large mixing bowl, whisk oil, buttermilk, eggs, and vanilla to combine, about 1 minute. Add hot water and whisk to combine, about 1 minute.

Add the dry ingredients and whisk just until combined, about 1 minute.

Then pour the batter into a parchment paper-lined baking pan. The picture below shows that the batter is thin.

Bake for 18-22 minutes or until a toothpick inserted into the center of the cake comes out clean with a few moist crumbs attached. Let cool for 10 minutes.

While the cake is cooling, start immediately with the frosting. Therefore, whisk the butter and cocoa until combined, and no lumps remain, about 1 minute. Gradually add the hot milk while whisking.

Then add the vanilla and powdered sugar and whisk until smooth and combined, about 1-2 minutes.

Spoon or pour the icing on top of the cake and spread evenly.

Top with pecans and set aside for 15-30 minutes to allow the frosting to set.

Expert tips for success
- The water should be hot but not boiling. The same is true for the milk.
- Don't overbake the cake, or it will be dry.
- Start immediately to prepare the icing as soon as you remove the cake from the oven. The cake should not cool any longer than 10 to 15 minutes max before you top it with the icing.
Peanut butter variation
Before you spoon the icing on top of the cake, you can apply a layer of peanut butter or peanut butter frosting on top of the cake and then spoon the chocolate icing on top. Either 1 cup (250g) peanut butter or half of my peanut butter frosting recipe is delicious.

Storage
This cake doesn't need to be refrigerated. You can store it in an airtight container at room temperature for up to 3 days. If you store it in the fridge, it will extend its shelf life a little, and you can store it up to 4 days.
You can also freeze the cake for up to 3 months. Therefore place single slices in the freezer for 1 hour that the icing hardens a little. Then wrap each slice in plastic wrap and place in freezer bags. To thaw, unwrap, and let sit on the counter for 2-3 hours.
