What you need to make flourless chocolate cake.
Cake
- Chocolate Chips. Semi-sweet sugar free chocolate chips are my choice for this recipe. You can also make this cake keto friendly by using keto chocolate chips.
- Butter If you are using unsalted butter you can add a half teaspoon of salt to the cocoa powder.
- Sugar Alternative. Use a granular sugar alternative, that measures like sugar, and that can also be baked with, for best results.
- Unsweetened Cocoa Powder. This is used in place of flour and to also add to the chocolate goodness in this recipe.
- Eggs. Use large eggs that are at room temperature.
- Vanilla Extract. Added for a bit of flavor balance.
- Optional Instant Coffee Granules (to bring out the richness of the chocolate flavor), sugar free powdered sugar (for dusting the cake before serving), and fruit (such as sliced strawberries).
Ganache.
- Sugar Free Chocolate Chips. Semisweet work well in this recipe.
- Heavy Cream.

Tips for making the best flourless chocolate cake
A simple round cake pan was used to make my flourless cake. You can make this recipe even easier by using a springform pan (baking times may differ).
More helpful tips for you.
- The eggs are added to the mixing bowl after the other ingredients have been added. This is to prevent the eggs from scrambling if the ingredients are too warm. If it seems like the ingredients are still hot, you can wait a minute or two before adding the eggs.
- It is normal for a flourless chocolate cake to puff or expand while baking in the oven. It should collapse as it cools. This process helps to make the cake dense and fudgy in the center.
- Allow the cake to fully cool before slicing. This is important as the cake needs to fully firm up to become fudgy and dense.

How to store chocolate cake.
Once the cake has fully cooled and set, it can be stored in an airtight container. When properly stored, flourless chocolate cake can keep for up to three days refrigerated when properly stored or up to three months when frozen.
