INGREDIENT NOTES
These are some of the key ingredients for this recipe. For a full list of ingredients, check out the recipe card below.
- All-purpose flour: Gives a light and airy cake. I prefer using all-purpose flour with a protein amount that is between 10-11%
- Sugars: The granulated sugar helps sweeten, as well as give moister to the cake. The brown sugar helps add extra toffee flavor to the cake.
- Baking powder and baking soda: Help leaven and rise the cake, so it has light and fluffy texture.
- Salt: Helps enhance the flavor of the chocolate cake.
- Coffee: I recommend using instant espresso coffee.
- Unsweetened Cocoa powder: I use high quality dutch process cocoa powder for the best flavor, my favorite is from Valrhona.
STEP BY STEP INSTRUCTIONS
Here is how to make and bake these Chocolate Mousse Cake. This recipe needs an hand whisk, two bowls, and a spatulas.
The full recipe is down below in the recipe card.
Preheat the oven at 175ºC/ 350ºF.
STEP 1: Start by browning the butter over medium in the skillet you'll be baking the cake in. If you don't have a skillet, brown the butter in a pan and bake the cake in baking pan.


STEP 2: In a bowl mix together the all-purpose flour, cocoa powder, granulated sugar, dark brown sugar, espresso powder, baking powder and salt. Then add the milk, vanilla extract and browned butter. Mix until smooth and combined.
STEP 3: Add the batter back into the skillet. Then in a small bowl, mix together the granulated sugar, dark brown sugar and cocoa powder. Sprinkle it over the cake batter. Lastly gently pour hot water over the back of a spoon, so the water gently spreads over the cake.


STEP 4: Bake for 30-35 minutes. Let it rest for 15 minutes before serving with vanilla ice cream.




EXPERT BAKING TIPS
- Use a kitchen scale: My default setting for my recipes is grams. It is the most precise way of measuring out your ingredients, I therefore highly recommend using a kitchen scale.
- Don't over mix your batter: I always use a spatula after everything has mixed together, to give it one final gentle fold together. This makes sure everything in the bottom of the mixing bowl has been mixed into the batter.
- Light vs. dark baking pans: For the best result, use an aluminum baking pan, greased with butter and lined with baking paper in the bottom. Aluminum pans are light in color and therefore attract less heat. That means it bakes more gently which results in a softer cake. If you use a black baking pan it'll attract a lot more heat. That will then give a darker crust, which can result in a dryer cake.
