What kind of sweetener is best for a keto cake:

For the low carb sweeter, I used Lakanto Classic Monk Fruit Sweetener, which is a cup-for-cup alternative to regular granulated sugar. There are other sweetener options available like Swerve and Pyure which are also 1:1 sugar replacement and are also excellent choices to use. But whatever low carb sweetener you choose, make sure that they are an exact 1:1 sugar replacement or else the sweetness will be off balanced.

Are there low carb chocolate chips?

For chocolate chips, I love Lily’s Sweets Dark Chocolate. And because it is sweetened with stevia, you do not need any additional sweetener.

Do you have to use espresso powder?

The espresso flavor enhances the chocolate flavor, but it’s optional. The cake will be good even without it. If you’ve never added coffee to chocolate cake though, try it! It boosts the flavor and is a secret ingredient in many chocolate recipes.

Tips for Making the Keto Cake

Use an 8″ round springform pan to easily make this cake. Don’t have a springform pan? Use an 8″ round cake pan, but line it with parchment paper hanging over the sides so you can easily pull it out to slice it.
This takes 3 bowls. Yes that’s a lot, but it will be what gives you the best cake texture.
Your eggs will mix best if they are at room temperature.
We used unsalted butter, but you can use salted butter if that is all you have.

Tips for Making the Ganache

You can make the ganache either on the stovetop or in the microwave.
Heat the cream until it is just barely at a boil. You want it hot and steaming, but not really bubbling.
Pour the hot cream over the chocolate chips. Make sure you have them in a bowl that can handle the heat of the cream.
Let the mixture sit for 5 minutes. The heavy cream will work its magic and melt the chocolate. You can cover the bowl if you’d like to trap in the heat.
After 5 minutes, use a rubber spatula or spoon and mix until the chocolate is smooth and creamy. It may take a bit of stirring, but it will eventually come together into silky smooth chocolate.

What to Serve with Keto Chocolate Fudge Cake

This cake pairs very well with a low carb vanilla ice-cream or whipped cream. You can just whip heavy whipping cream or add a touch of powdered monk fruit for a bit of sweetness to offset the rich chocolate.
