3 Ingredient Chocolate Cake

It doesn’t get any easier than this super easy flourless chocolate cake. All you need is:

  • eggs – use large eggs (approximately 55g)
  • butter – use unsalted butter for this recipe
  • dark chocolate – use a good quality dark cooking chocolate (you can buy cooking chocolate from the baking section of the supermarket). I like Cadbury, Nestle or Lindt brands – but you can use any good quality brand you like. Note: cooking chocolate melts easier than regular chocolate making it a perfect option for this dessert!

That’s it… just 3 basic ingredients!!!

3 Step Recipe

Note: Scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.

Step 1 – Melt The Butter And Dark Chocolate

Use a microwave, Thermomix or stove-top to melt the butter and chocolate together. Do not overcook – heat until just melted and smooth.

Step 2 – Beat The Eggs

Use hand-held beaters, a stand-mixer or a Thermomix to beat the eggs until pale, creamy and doubled in size. This will take approximately 5 minutes.

How To Cook A Cake In A Water Bath

A water bath is a method of adding liquid to an oven during baking to ensure a moist cooking environment.

There are 2 different ways of cooking with a water bath in an oven.

  1. Placing a tray of water on the bottom shelf of the oven while your recipe bakes on the shelf above. This method keeps the oven moist resulting in beautifully moist recipes that don’t crack.
  2. Placing the dish directly into a tray of water and allowing the heat of the water combined with the moist hot oven to bake the recipe.

In this recipe – we use option 2 as it’s the BEST way to get that amazing mousse-like texture in your flourless chocolate cake.

Preparing The Tin

It’s important to prepare the tin properly to ensure perfect cooking and easy removal of the cake.

  • Lightly grease the base and sides of a 20cm round springform tin.
  • Cut out a circle of baking paper and line the base of the tin.
  • Wrap foil around the outside edges of the tin (ensuring that the join at the base is well covered – to avoid water seeping in).
  • Place the tin into a large deep baking dish.
  • Once the mixture has been added to the tin, very carefully pour boiling hot water into the large baking dish so that it goes 2/3 of the way up the side of the springform tin (ensure no water gets into the springform tin).

Baking In A Water Bath

  • Very carefully place the large baking dish into the oven.
  • The heat of the moist oven and hot water will slowly cook the cake, while retaining a very moist, rich and mousse-like texture.
  • Once the cake begins to set around the outside edges (the middle should not be set), remove the large baking dish from the oven.
  • When safe to do so, gently remove the springform tin from the baking dish and set aside to cool completely at room temperature (the middle of the cake will continue to cook during this stage).
  • Place the cake (still in the tin) into the fridge overnight before serving.

Tips For Making This Recipe

Use a good quality dark cooking chocolate – this ensures a beautifully smooth and rich flourless chocolate cake. I recommend Cadbury, Nestle or Lindt brands.

Bake the cake in a water bath – refer to my tips above. This ensures a very rich, moist and mousse-style dessert cake.

Only bake until the edges have set – don’t overcook this cake. Simply bake until the outside edges have set (the middle will continue to cook and set once removed from the oven).

Storing – this cake can be stored in the fridge for 1-2 days. Note: the cake will harden slightly in the fridge so allow to come to room temperature before serving.

Freezing – this cake can be frozen in an airtight container for up to 3 months. Allow to defrost in the fridge overnight before serving.

Serving suggestions – Decorate with chocolate ganache, icing sugar, fresh berries, whipped cream or sifted cocoa powder or icing sugar.

  • Melt on 50% power in the microwave on 30 second bursts for 2-3 minutes or until the chocolate and butter has melted (stir every 30 seconds with a dry metal spoon). You can use a double-boiler on the stovetop if you prefer.
  • Gently fold 1/4 of the egg mixture into the chocolate. Repeat 3 more times with the remaining egg mixture.
  • When the mixture is completely combined, pour it into the prepared springform tin.
  • Boil water and carefully pour it into the large baking tray until it covers 2/3 of the sides of the springform pan.
  • Bake in the oven for approximately 30-35 minutes or until the chocolate cake begins to set on the outside edges (not in the middle).
  • Remove the pan from the oven and set aside until the boiling water has cooled slightly.
  • When it’s safe to do so, carefully remove the springform tin from the water bath and set aside to cool completely.

    Is it whole eggs or egg whites only? Whole eggs seems quite runny (mine currently in the oven)
