Ingredients

Keto Chocolate: We suggest avoiding sugar-free keto chocolate chips as they may not melt well. Instead, opt for a chopped unsweetened dark chocolate bar for this keto flourless chocolate cake. While it may taste bitter on its own, you won’t notice the bitterness once it’s baked.

Butter: Use unsalted butter or grass-fed butter. Opt for good quality butter, preferably in stick form. Cheaper brands and block butter may have added water. 

Granulated sweetener: You can replace regular granulated sugar with powdered erythritol or monk fruit sweetener or any granulated sugar substitute you prefer.

Salt: Salt is a must for this keto flourless cake as it boosts the sweetness!

Espresso powder: You don’t have to add espresso, but it enhances the chocolate flavor!

Vanilla extract: It is also optional, but it adds a hint of vanilla flavor that intensifies the chocolatey taste. 

Eggs: Use room temperature large eggs.

Unsweetened Cocoa Powder: Opt for a high-quality cocoa powder or Dutch cacao powder to avoid clumps and ensure a rich chocolatey taste. Cheaper options may lack in both texture and flavor.

To make a keto flourless chocolate cake, you will need the following ingredients:

KETO FLOURLESS CAKE

  • 1 cup unsweetened chocolate
  • 1/2 cup butter
  • 3/4 cup granulated sweetener 
  • 1/4 tsp salt
  • 1 tsp vanilla extract (optional)
  • 1 tsp espresso powder (optional)
  • 3 large eggs 
  • 1/2 cup cocoa powder

CHOCOLATE GANACHE

  • 1 cup coconut milk
  • 1 1/4 cups chocolate chips

Instructions

Make the Flourless Keto Chocolate Cake:

Preheat the oven to 350°F (180°C). Grease an 8-inch round cake pan with a springform, line the sides and bottom with parchment paper, and grease again using melted butter or coconut oil. Set aside.

In a non-stick saucepan over low heat, melt the chocolate and butter. Alternatively, you can use a microwave-safe bowl and heat the ingredients in 30-second intervals until melted, smooth, and shiny.

Transfer the chocolate mixture into a large mixing bowl. Whisk in the eggs, sweetener, vanilla extract, and espresso powder until everything is well combined.

Mix in the cocoa powder until you can’t see any more cocoa bits. Pour the cake batter into the prepared cake pan and pop it in the oven on the center rack for around 25 minutes.

The cake is done when the sides are set and a thin, slightly firm crust forms on top. Avoid overbaking to prevent dryness.

Remove the cake from the oven and let it cool for one hour in the pan. Afterward, carefully loosen the edges of the springform pan.

Simply place a plate on the cake and invert it, allowing the bottom to become the top. Remove the remaining parchment paper from the surface.

Decorate the Cake:

Add a sprinkle of cocoa powder or powdered sugar-free sweetener to the flourless chocolate cake for decoration, or opt for a ganache topping.

In a non-stick saucepan, combine sugar-free chocolate chips and heavy cream. Heat over low-medium heat, stirring until melted and glossy.

Drizzle the cooled cake with the poured mixture and enjoy each slice with fresh berries or keto whipped cream.

Tips for Making Keto Flourless Chocolate Cakes

To prevent the flourless cake from sticking, line the pan with parchment paper. Greasing the cake pan alone won’t suffice. Instead, cut a piece of parchment paper to fit the base, put it in a greased pan, and then grease it again. This will ensure the cake is easily removable.

To avoid dryness and achieve a fudgy, melt-in-your-mouth texture, it’s important not to over-bake the flourless chocolate cake. The cake should be done when the center is just set, and a toothpick inserted into the center comes out slightly moist. Remember that it will continue to cook while cooling and firm up a bit in the fridge.

If you don’t consume dairy, you can easily substitute butter with non-dairy butter or ghee. You may also use coconut oil or another light-flavored healthy oil. If you choose coconut oil, go for refined coconut oil to minimize the coconut flavor.

To make a paleo keto chocolate cake, just swap the sweetener with a cup of coconut palm sugar and use coconut oil instead of butter.

To complement the rich and decadent flavors of keto flourless chocolate cake, consider serving it with a dollop of keto whipped cream or a scoop of sugar-free ice cream. The cool and creamy textures will balance the intensity of the chocolate while adding a touch of indulgence. 

Fresh berries, such as raspberries or strawberries, can provide a refreshing contrast and a burst of natural sweetness without compromising the low-carb nature of the dessert. For an extra special touch, sprinkle some chopped nuts, like toasted almonds or hazelnuts, on top for added crunch. 

Enjoying a cup of black coffee or a warm herbal tea alongside the cake can also enhance the overall dining experience, making it a satisfying and guilt-free treat.

How to Store Keto Flourless Chocolate Cake 

To store leftover flourless chocolate cake, refrigeration is recommended, especially if it is frosted. Keep it covered or in a sealable container for freshness up to 2 weeks.

You can freeze this flourless chocolate cake. Simply store any leftover cake in a freezer-friendly container, and it will stay fresh in the freezer for up to 6 months.

To enjoy this keto chocolate cake from frozen, thaw it overnight in the fridge. On the day of consumption, let it thaw at room temperature. Avoid reheating in the oven or microwave, as it will thaw and cook simultaneously.
