Ingredients You’ll Need

• 4 large eggs, separated: The eggs are essential for the cake’s structure, providing richness and helping it rise. Make sure they’re at room temperature for better mixing.
• 1/2 cup Swerve powdered sweetener: A fantastic low-carb sugar substitute, Swerve offers sweetness without the calories or glycemic impact of regular sugar. You can use powdered erythritol if preferred.
• 2 tsp lemon zest: This adds a vibrant kick of citrus flavor. Always zest from organic lemons to avoid pesticides if you can!
• 1 1/2 cups almond flour, sifted: Almond flour gives the cake a moist and tender crumb while keeping it low in carbs. If you’re in a pinch, look for finely ground hazelnut flour as an alternative.
• 1/2 cup frozen blueberries: They add a burst of juicy sweetness. Frozen works best here, but if using fresh, just coat them well to prevent sinking.
• 1 tbsp almond flour, for coating the blueberries: This helps the blueberries to stay suspended in the batter instead of all sinking to the bottom during baking.

How to Make Keto Lemon Cake With Blueberries

1. Preheat the oven and prepare the pan: Start by preheating your oven to 350°F (175°C). Line the bottom of an 8-inch springform pan with parchment paper and grease it with cooking spray to ensure easy removal later.

2. Make the batter: In a mixing bowl, beat the 4 egg yolks and 1/2 cup Swerve powdered sweetener on medium-high speed for about 3–5 minutes until the mixture is pale, thick, and fluffy. Add in the lemon zest and sifted almond flour, mixing until just combined.

3. Whip the egg whites: In a separate bowl, beat the 4 egg whites on medium-high speed for 2–3 minutes until stiff peaks form. This step is crucial as it provides the cake with its light and airy texture.

4. Prepare blueberries: Toss the 1/2 cup of frozen blueberries with 1 tablespoon of almond flour to coat them. This helps prevent them from sinking in the batter and gives a nice texture.

5. Fold the mixtures: Gently fold ¼ of the whipped egg whites into the yolk mixture to loosen it. Then gradually fold in the remaining egg whites until no streaks remain. Lastly, fold in the coated blueberries gently to incorporate without mashing them.

6. Pour the batter and bake: Pour the batter into your prepared pan, smoothing the top with a spatula. Bake in the preheated oven for about 30 minutes, or until a toothpick inserted into the center comes out clean, and the top is lightly golden brown.

7. Cool and serve: Once finished, let the cake cool in the pan for about 15 minutes before transferring it to a wire rack. Dust with a little more powdered sweetener and top with fresh blueberries before serving.

Storing & Reheating

To store your Keto Lemon Cake with Blueberries, let it cool completely and then cover with plastic wrap or store it in an airtight container at room temperature for up to 3 days. For longer freshness, refrigerate for about a week. If freezing, wrap it tightly in plastic wrap and aluminum foil; it should last for up to 3 months. When you want to enjoy it again, pop it in the oven at 350°F for about 10—15 minutes, but keep in mind that the texture might change slightly, so serving it with a dollop of whipped cream or a scoop of sugar-free ice cream can help refresh it!

Chef’s Helpful Tips

• Monitor the egg whites as you whip them; don’t overbeat—it should be just right for lightness.
• If the blueberries sink, try reducing the almond flour slightly or increasing the egg whites for extra lift.
• Feel free to experiment with flavors! Add a splash of vanilla extract or almond extract for a different dimension.
• If you prefer a sweeter cake, adjust the powdered sweetener to your taste preference.
• For a citrus twist, consider using lime or orange zest alongside or instead of lemon.

This recipe emphasizes the balance of rich flavors and health-conscious choices, embodying a perfect dessert that doesn’t skimp on taste. The combination of zesty lemon and fresh blueberries creates a mouthwatering experience unlike any other, perfect for sharing or indulging yourself.

Recipe FAQs

Can I use fresh blueberries instead of frozen?

Yes, fresh blueberries can be used, but they may sink more easily in the batter. To help prevent this, coat them with almond flour just like the frozen ones before folding them into the batter.

How can I make this cake dairy-free?

This cake is already dairy-free, but if you want to add a creamy topping, consider using coconut whipped cream for a delicious, dairy-free alternative.

What should I do if my cake sinks in the middle?

A sunken cake can result from underbaking or overly incorporating the batter after adding the egg whites. Make sure to whip the egg whites to stiff peaks, and also check your oven’s accuracy using an oven thermometer.

How can I enhance the lemon flavor?

To amplify the lemon flavor, consider adding a bit of lemon juice along with the zest. You can also serve the cake with a drizzle of lemon glaze made from powdered sweetener and lemon juice.
