Helpful Tips and FAQs

Can I make this recipe in a large cake instead of mini cakes?

Yes, you can. I recommend that you not go any bigger than an 8-inch round pan. Cut the larger cake into the same number of portions as our mini cakes to maintain the same nutritional information.


King Arthur Keto Wheat Flour – The best results are achieved by using the King Arthur Keto Wheat flour, but it can be hard to find. Carbalose flour is a good substitute as well. Almond Flour and Coconut flour will result in a denser cake and less like a sponge cake.

Sugar-Free Chocolate Chips – I am using Lily’s Sugar-Free Dark Chocolate Chips. Not all brands of sugar-free chocolate chips have the same amount of carbs. when substituting, be aware of the possible changes to the net carbs. Other brands work well. You can opt for sugar-free milk chocolate chips if you like a sweeter flavour. Carob Chips are not reccomended.

Sour Cream – Plain unsweetened yogurt or unsweetened Greek yogurt is a good substitute for the sour cream in this recipe.

Butter – You can substitute the butter with canola or a similar non-flavoured oil.

Heavy Whipping Cream – I do have a recommended substitute for the heavy cream. Even cool whip will not yield the fluffy mousse we aim to achieve.

Serving Ideas

These amazing little cakes look awesome when drizzled with a small amount of Walden farms or topped with a dollop of whipped cream Chocolate Syrup.
