Ok… let’s compromise on half for me, half for you.

My chocolate-addict of a husband has decided to go on an almost no-sugar kind of diet. He said he wants his 28-year old bod back… good luck, bud.

Therefore, being the good wife and friend that I am, I decided to play a bit in the kitchen and possibly create a Valentine’s Day dessert that wouldn’t interfere with his diet. The only way his journey will work is if there’s, one, support and, two, chocolate fudge cake.

Chocolate Fudge Cake in a baking dish

Imagine a decadent chocolate cake that is a cross between a chocolate soufflé and fudge cake. That’s this cake wrapped in a nutshell. It will rise up and cook up like chocolate soufflé, but without the molten center. The texture is fudgy and denser than a soufflé dessert. Make sense? Coo’.


Don’t worry – the ingredients are NOT anything fancy schmancy. You will need the following:

  1. butter
  2. unsweetened baking chocolate
  3. stevia/sweetener
  4. almond flour
  5. heavy cream
  6. cocoa powder
  7. and eggs

There’s only 1 or 2 ingredients up there that might not be in your pantry – almond flour and stevia. Put them on your grocery list, stat!


1. Preheat your oven to 350F and grease your baking dish.

2. Melt the butter and baking chocolate together. The one thing I couldn’t really skimp out on was the butter, and you will need quite a bit. 12 tablespoons… I KNOW! This cake serves about 6, which is equal to 2 tablespoons of butter per serving.

3. Combine wet ingredients. In a small bowl, whisk together the heavy cream and vanilla.

4. Combine dry ingredients. In another bowl, combine the almond flour, cocoa and salt.

Three bowls with melted chocolate, whipped eggs and dry ingredients.

5. Whip the eggs. In a stand mix or a large bowl with a hand held beater, whisk the eggs on high for 1 minute. Gradually add your sweetener and continue to beat for 5 minutes until the eggs are pale yellow.

6. Make the batter. Slowly add the chocolate and melted butter mixture. Mix until combined, then slowly add the almond flour mixture and continue to beat for 1 minute or until thickened.

7. Bake in a Water Bath. Transfer the batter to your baking dish. Place the baking dish with the batter on a sheet pan and pour hot boiling water in the sheet pan. This will bake your cake in a water bath like with a cheesecake. Bake 35 to 40 minutes until the cake is set and puffed up. It should be 160F in the center.

8. Cool and Serve. Remove the finished cake from the oven and let cool for 10 minutes before serving. Scoop this cake straight out of the baking dish and serve it as is, or add a tablespoon of low carb whipped cream on top. The chocolate fudge cake tastes best while still warm.

  • Use room temperature eggs and cream. This helps everything mix together and will result in a smoother batter when you add the dry ingredients.
  • Measure accurately. Level your almond flour using a spatula or butter knife to ensure you are using the right amount.
  • Use the water bath. Don’t skip the water bath when baking this cake. The water bath helps give this cake it’s gooey, fudgey center.

        I don’t think you plugged in the amount of servings. I just used two other calculators to make sure I was getting the correct amount and on both it’s coming up as 7.3 grams of carbs.

  10. Teresa Vera says:

    Question… is the stevia you are referring to here regular stevia (which is just that, pure stevia) or stevia for baking blend which is a mixuture of stevia and other sweetener? Pure stevia is very strong and a little goes a long ways… this seems to be too much. I personally don’t like stevia for baking as to me it tastes a little bitter. For baking I normally substitute with xylitol which replaces sugar 1:1. If I decided to replace with xylitol, how much would I use?

    1. Katerina Petrovska says:

      Yes, the stevia baking blend is what I meant. I’ll make sure to fix that in the recipe card. Thank you for pointing that out!! 🙂 But, you can use any other sweetener with the same amount. I use whatever I have on hand. 🙂

      1. Teresa Vera says:

        Super! Thank you so much… I will be making this over the weekend…
