This recipe uses simple, everyday ingredients that you probably already have in your keto baking pantry.

The following are all the ingredients needed: Note that the full printable recipe card is at the bottom of the page.

• Finely milled almond flour: You’ll want to measure and sift your almond flour even if it’s finely milled for the best results. I do not recommend an almond meal, as it is too heavy a flour.
• Unsweetened cocoa powder
• Sugar substitute: This recipe calls for a granulated sugar substitute.
• Room temperature eggs: The recipe calls for six large eggs, which are not uncommon in a pound cake recipe, but don’t be alarmed; it does not have an eggy flavor.
• Sour cream: Choose full-fat only. If you can’t easily source sour cream, full-fat Greek yogurt will also work well.
• Butter: Choose unsalted butter and make sure it’s at room temperature.
• Vanilla extract: It’s a classic extract choice for pound cake, but feel free to experiment with other extracts.
• Baking powder: This is the leavening agent that works best with heavy flour alternatives like almond flour.
• Salt-sea salt is best, but regular table salt also works. Salt helps bring out all the flavors in the cake.

Great Tips For Making A Gluten-free Chocolate Sour Cream Pound Cake

• Always choose real, unsalted butter and full-fat sour cream for this low-carb cake.
• Make sure your almond flour is fresh and from a quality brand. It will make a difference in the final outcome of the cake. Unlike wheat flour, almond flour will vary by brand.
• Always use large-grade A eggs, as it’s standard in most recipes.
• Choose your favorite cocoa powder, and mine happens to be Hershey’s cocoa powder because of its consistent results.
• Be sure to use fresh baking powder, as it is key when baking, especially when keto baking since the alternative flours are heavier.
• Store leftovers in the refrigerator in an airtight container for up to five days or freeze for up to three weeks.

Why Put Sour Cream In Chocolate Cake?

If you are wondering if the flavor of sour cream marries well with that of chocolate, I am here to reassure you. You see, the flavor of sour cream is barely noticeable.

However, the benefits of adding sour cream to a chocolate cake are what gives this recipe a fudgy, moist cake crumb that my family has declared the best keto chocolate cake they have ever tasted.

It’s a winning combination that you simply must try. What’s great about this recipe is that you can also substitute the sour cream for full-fat Greek yogurt and still get the same delicious results.

Best Sugar-free Sweetener Options For Low Carb Chocolate Sour Cream Cake

As far as which sugar substitute to use for this chocolate sour cream keto pound cake, I have a few recommendations. If you are a regular on our site, you know I’m a huge fan of Lakanto Monk Fruit.

This is because the texture of Lakanto is spot on since there is barely any aftertaste. It is a monk fruit sweetener that is an erythritol blend. If you have not given this all-natural sweetener a try, you have no idea what you are missing. 

I love that Lakanto Monk Fruit is all-natural, and it gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. And it has zero calories and zero glycemic impact. 

That being said, I’m also partial to Swerve, another erythritol blend.  

It works well in this keto-friendly chocolate sour cream pound cake recipe and is a great choice if you are looking for a sugar substitute that has no bitter aftertaste and measures just like sugar.

Swerve is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors. Like Lankanto, Swerve has a 0% impact on blood sugar.

I know some of you are stevia fans; if that’s you, you can use the stevia and erythritol-based brand Pyure in this recipe.

However, it’s important to note that if you are using Pyure, you will want to use 1/2 the amount called for in this recipe since it’s a much sweeter option. 

I’ll also add that the use of stevia with chocolate-based recipes can intensify the bitter aftertaste many people seem to dislike with stevia.

Lastly, if you cannot easily find a more natural sugar substitute, you can also use Splenda with great success. You will want to use the Splenda, which has a bulking agent. It’s the one that comes in larger bags.

I don’t recommend Splenda Bake because it’s actually a half-sugar, half-sucralose product and will be too high in carbs to be considered keto-friendly.

Baking In Other Cake Pans 

I chose to bake this easy chocolate cake in a 9×5-inch pan for 35–45 minutes, but you can also bake the cake in the following pans:

​12×12 pan for 35-40 minutes

Two 8-inch pans for a layered cake for 25–35 minutes

Bundt pan (9.5-inch ceramic coated 12-cup capacity bundt pan) for 40–45 minutes.
