Low Carb Blueberry Cake

Low carb cake is equally as delicious as a traditional cake when made with quality ingredients. This easy cake recipe uses butter and heavy cream to create a rich flavor and tender texture. Brown sugar provides a delicate sweetness, while lemon offers a citrus taste—the whole cake bursts with sweet, tart blueberries.

• Quick and Easy - This recipe uses basic ingredients, requires little mixing, and bakes quickly.
• Low-Carb - One serving of low carb blueberry cake has only 20g of carbohydrates and 14g of sugar per slice —this is half the quantity of carbs and sugar in traditional cakes. Similarly, there is 7g of protein and 3g of fiber per serving.
• Delicious Cake - This gluten-free blueberry cake is delicately sweet and bursting with berries. The fluffy cake has a tender crumb and nutty flavor from the almond flour.

See the recipe card for ingredient quantities.

Instructions

Make this cake with the biscuit mixing method versus the typical creaming method you see in most cake recipes.

STEP 1 (PREHEAT) - Preheat the oven to 375 degrees F. Grease a 9-in springform pan.

STEP 2 (DRY INGREDIENTS) - Mix the almond flour, brown sugar, baking powder, salt, and lemon zest in a large bowl until combined. 
STEP 3 (CUT IN THE BUTTER) - Using a pastry blender or two forks, cut the cold butter into the dry ingredients until pea-sized pieces remain.

STEP 4 (WET INGREDIENTS) - Whisk the heavy cream, egg, and vanilla extract in a large liquid measuring cup or medium bowl. Pour the wet ingredients into the dry ingredients and mix until combined. Fold in the blueberries.

STEP 5 (BAKE) - Pour the cake batter into the prepared dish. Spread the batter into an even layer and sprinkle the turbinado sugar. Bake for 20-25 minutes until a toothpick inserted into the middle of the cake comes out clean, and the top of your cake is golden brown. Allow the cake to cool before removing it from the pan.

Substitutions

• Blueberries - Raspberries, Blackberries
• Light Brown Sugar - Dark Brown Sugar, Granulated Sugar
• Lemon Zest - Orange Zest, Lime Zest
• Vanilla Extract - Almond Extract (use half the quantity)

Variations

• Keto Blueberry Cake - Swap the light brown sugar for a sugar substitute like monk fruit sweetener, Stevia, or another low-carb sweetener. Add the dry sugar to the dry ingredients at the beginning of the mixing process. Sprinkle the cake with Truvia instead of turbinado sugar.
• Cinnamon - Add ½ teaspoon of ground cinnamon.
• Add Chocolate Chips - Stir in ⅓ cup of sugar-free white chocolate chips with the blueberries.

Try my banana cake with peanut butter frosting for another almond flour-based cake.

Suggested Equipment

• Large Mixing Bowl
• Pastry Blender
• 9-Inch Springform Pan
• Rubber Spatula

Storage

Tightly wrap the cake or store cake slices in an airtight container for up to 3 days at room temperature. For a longer shelf life, store the cake in the refrigerator for up to one week.
Can you freeze the low-carb cake? Wrap the cooled cake in plastic wrap, then foil—or place slices in a freezer bag. Freeze the cake for up to 3 months — thaw it entirely before eating.

How to Serve Blueberry Cake

Serve at room temperature or warm. Place one slice of cake on a microwave-safe dish and heat for 15-30 seconds. Top cake slices with zero-sugar whipped topping. You can also slather slices in room-temperature cream cheese or butter. For added decadence, make a batch of my chantilly cream but swap the sugar for monk fruit sweetener.

Expert Tips

1. Use cold butter and cream. This cake is made via the biscuit mixing method, which means cold butter is cut into the dry ingredients. The cold butter melts in the oven, creating pockets of steam and tender cake.
2. Check the expiration of your baking powder. The cake's leavening relies on baking powder. Check the expiration date before using it for a good rise.
3. Grease the baking pan well to prevent sticking. You can also line the pan with parchment paper round.
