Ingredients

For the Cake:

• 2 cups superfine almond flour
• 1/2 cup granular erythritol
• 1/2 cup unsalted butter, melted
• 1/4 cup coconut flour
• 1 tablespoon baking powder
• 5 large eggs

• 1/4 cup fresh lemon juice

For the Sugar-Free Lemon Drizzle:

• 1/2 cup powdered sweetener
• 2 tablespoons fresh lemon juice (adjust for desired consistency)

How To Prepare Keto Lemon Cake Recipe

1. Preheat & Prep with Care

First things first set your oven to 350°F (175°C). While that’s warming up, take a moment to grease your baking pan with butter (my go-to for extra flavor), or use parchment paper if you prefer an easier cleanup. I always line mine it makes lifting the cake out so simple.

2. Blend Your Dry Ingredients

In a large bowl, whisk together the almond flour, coconut flour, erythritol, and baking powder. I like to make sure everything is lump-free—gives a smoother batter and a better crumb in the final cake.

3. Mix the Wet Stuff Separately

In another bowl, crack in your eggs and give them a good beat. Then stir in the melted butter, lemon zest, vanilla extract, and fresh lemon juice. I recommend zesting the lemon before juicing—it’s just easier.

4. Bring It All Together

Now, pour the wet mixture into the dry ingredients gradually. I use a spatula when I want a more hands-on feel, but a mixer works great too. You’re aiming for a thick, smooth batter—don’t overmix.

5. Time to Bake!

Pour your batter into the prepared pan, smooth the top, and pop it in the oven. Bake for about 35–40 minutes. I always check with a toothpick at 35—if it comes out clean, you’re good. Let the cake rest in the pan for 10 minutes, then move it to a wire rack to cool completely.

6. Add That Lovely Lemon Drizzle

While the cake cools, mix your powdered sweetener with lemon juice until you get a smooth glaze. I like to keep it just pourablenot too runny. Drizzle it generously over the cooled cake and give it time to set before slicing. Trust me, it’s worth the wait.

Note: Make sure the cake is completely cool before adding the drizzle to prevent it from melting into the cake. For a more intense lemon flavor, you can add a bit more zest or a drop of lemon extract.

How To Decorate And Serve

You can add thin lemon slices or a few sprigs of fresh mint on top to enhance the presentation. For a touch of elegance, sprinkle some finely grated lemon zest or a few chopped toasted almonds.

My Tips Tips For Success!

➢ This type of almond flour creates a finer, softer crumb in the cake. Regular almond meal can make the texture gritty or dense, so using superfine flour really helps keep the cake tender and light.

➢ After melting the butter, let it cool to just warm or room temperature before mixing it with the eggs. Pouring hot butter into eggs can cause them to cook or scramble, which will affect the batter’s smoothness and the cake’s final texture.

➢ The zest contains essential oils that give a fresh, vibrant lemon flavor. Just adding juice alone won’t deliver the same bright citrus punch, so make sure to finely grate the lemon peel without the bitter white pith.

➢ Almond and coconut flours can dry out quickly if overbaked. Check your cake with a toothpick about 5 minutes before the recommended time; remove it once the toothpick comes out clean or with just a few crumbs attached to avoid dryness.

➢ If the cake is still warm when you add the lemon drizzle, the glaze will melt and soak in, losing its shine and texture. Cooling the cake completely lets the drizzle set up nicely on top for that perfect finish.

Additions For Make More Delcious

To make your keto lemon cake recipe even more delicious, try these tasty additions:

1. Fresh Berries: Stir in blueberries or raspberries to add natural sweetness and a juicy burst with every bite.

3. Toasted Almonds: Sprinkle chopped toasted almonds on top or fold them into the batter for extra crunch and nuttiness.

4. Vanilla Extract: A teaspoon of high-quality vanilla extract deepens the flavor and complements the lemon beautifully.

5. Cream Cheese Swirl: Mix softened cream cheese with a bit of sweetener and swirl it into the batter before baking for a creamy surprise inside.

6. Poppy Seeds: Add a tablespoon of poppy seeds to the batter for a classic lemon-poppy seed flavor and subtle crunch.
