Keto Sour Cream Cake

Unlike other low carb cakes, this sour cream cake has minimal ingredients and is easy to prepare. Most keto dessert recipes use a blend of low carb flours but this cake only calls for almond flour. Sour cream and melted butter keep the texture moist and velvety while vanilla adds a delicious flavor.

Expect an incredibly moist almond flour cake with a delicate crumb and luscious texture. It’s topped with a light, whipped cream cheese frosting and fresh strawberries and blueberries. This low carb dessert recipe is absolutely delicious and so simple to make. I promise you’ll never miss the carbs in this keto cake.

Sugar-free Whipped Cream Cheese Frosting

This sugar-free whipped cream frosting is my husband's favorite. You'll find a hint of butter in the in the background and just enough vanilla to balance the tartness of the cream cheese. Starting with cold cream cheese ensures that the heavy cream will whip, producing a more stable frosting.

Erythritol based sweeteners will sometimes recrystallize after sitting in the refrigerator - especially in moist confections. We've all experienced "crunchy" frostings or cake fillings. To reduce this effect, I use a finely powdered sweetener like Sukrin Icing Sugar (Melis), Swerve Confectioners, Lakanto Powedered or Besti Monk Fruit with Allulose (Powdered).

To get the best results in your keto frosting recipes, make sure to beat the icing sugar with butter or cream cheese for several minutes to encourage it to dissolve. When completely dissolved, less/finer crystals form. Another trick is to use less erythritol and augment sweetness with stevia.

Tips for the perfect keto cream cheese frosting:

• Start with cold cream cheese. This ensures that the heavy cream will whip well and produces a more stable frosting.
• For the smoothest frosting, use a finely powdered sweetener.
• Make sure to beat the icing sugar with the cream cheese first for several minutes so it completely dissolves. This helps prevent crystals from forming.
• Then, beat in the softened butter.
• Next add the heavy cream, a little at a time, whipping until the frosting is light and fluffy.

Low Carb Baking Simplified!

Have you ever felt overwhelmed by the steps required to make a cake? I know I have. I thought it all had to be done in one day. Then, I discovered the secret of professional cake decorators - don’t do it all in one day!

I make my cakes in advance and cool them completely before wrapping well in cling film and refrigerating until needed. Make this sour cream cake a few days ahead of time and park it in the fridge until you’re ready to frost it.

If you plan to frost this sour cream cake today and serve it tomorrow, store it uncovered in the fridge overnight or at least 6 hours without the fruit. Refrigerating it uncovered, ensures that the frosting chills and forms a thin skin that won’t stick to the cling film. Add the fruit to decorate just before serving or several hours before serving and lightly cover with cling film.

NOTE: When decorating, be sure to use the fruit sparingly. We low carb Keto dieters keep our fruit consumption to a minimum in order to keep blood sugars low. Using fresh berries as a garnish allows us to enjoy without overdoing it. And, it provides a pretty patriotic twist making this sour cream cake a winner for all the summer holidays.
