Ingredients

Dry Ingredients

2 cups finely sifted almond flour

¼ cup coconut flour

1 tablespoon baking powder

¼ teaspoon xanthan gum for additional structure

¼ teaspoon fine sea salt

Wet Ingredients

6 large eggs, separated into whites and yolks

½ cup powdered erythritol or powdered monk fruit sweetener

¼ cup unsalted butter, melted and cooled

¼ cup full-fat cream cheese, softened

¼ cup heavy whipping cream

2 teaspoons pure vanilla extract

1 teaspoon almond extract (optional)

1 teaspoon fresh lemon zest for brightness

½ teaspoon cream of tartar

Optional Flavor Variations

1 tablespoon unsweetened cocoa powder for chocolate flavor

1 teaspoon cinnamon

½ teaspoon espresso powder

Sugar-free chocolate chips

Unsweetened shredded coconut

Finely chopped pecans or walnuts

Fresh raspberries or blueberries for garnish

Equipment

Two large mixing bowls

Electric hand mixer or stand mixer

Rubber spatula

Fine mesh sieve

8-inch round cake pan

Parchment paper

Cooling rack

Kitchen scale for best accuracy

Preparing the Cake Pan

Preheat your oven to 325°F (163°C).

Grease the cake pan lightly with butter.

Line the bottom with parchment paper.

Dust lightly with almond flour if desired.

Set aside while preparing the batter.

Step 1: Separate the Eggs

Carefully separate the egg whites from the yolks.

Ensure absolutely no yolk enters the whites because even a tiny amount of fat can prevent the whites from whipping properly.

Allow both bowls to come to room temperature for about 20 minutes before mixing.

Room-temperature eggs whip much better than cold eggs.

Step 2: Mix the Dry Ingredients

In a medium bowl combine:

Almond flour

Coconut flour

Baking powder

Salt

Xanthan gum

Whisk thoroughly until every ingredient is evenly distributed.

Sifting the mixture removes lumps and produces a finer cake texture.

Step 3: Prepare the Yolk Mixture

In another bowl beat together:

Egg yolks

Powdered sweetener

Cream cheese

Butter

Heavy cream

Vanilla extract

Almond extract

Lemon zest

Mix for 3–5 minutes until smooth, creamy, pale, and slightly fluffy.

No lumps should remain.

Step 4: Combine Dry and Wet Ingredients

Gradually add the dry ingredients into the yolk mixture.

Mix gently until completely incorporated.

Avoid overmixing.

The batter will become thick but smooth.

Set aside.

Step 5: Whip the Egg Whites

Place the egg whites into a perfectly clean mixing bowl.

Add cream of tartar.

Using medium speed, beat until foamy.

Increase to high speed.

Continue beating until stiff glossy peaks form.

The egg whites should stand upright when the beaters are lifted.

Avoid overbeating, as dry egg whites become difficult to fold into the batter.

Step 6: Fold the Egg Whites

Add one-third of the whipped egg whites into the batter.

Mix gently to lighten the batter.

Add the remaining egg whites in two more additions.

Use a rubber spatula.

Fold slowly from the bottom upward.

Rotate the bowl while folding.

Do not stir vigorously.

Maintaining as much air as possible is the key to creating the signature cloud-like texture.

Step 7: Fill the Cake Pan

Transfer the batter into the prepared pan.

Spread gently using an offset spatula.

Lightly tap the pan once or twice to remove only large air bubbles.

Avoid excessive tapping because too much air loss will reduce the cake’s height.

Step 8: Bake

Bake for approximately 35–45 minutes.

The top should become lightly golden.

The cake should spring back gently when touched.

A toothpick inserted into the center should come out mostly clean with only a few moist crumbs.

If the top begins browning too quickly, loosely cover it with aluminum foil during the final 10 minutes.

Step 9: Cool Properly

Remove the cake from the oven.

Allow it to cool inside the pan for 15 minutes.

Carefully run a knife around the edges.

Transfer to a cooling rack.

Allow the cake to cool completely before slicing.

Warm cake is fragile and may collapse if cut too early.

Optional Keto Whipped Frosting

Ingredients

1 cup heavy whipping cream

3 tablespoons powdered erythritol

1 teaspoon vanilla extract

Whip until medium peaks form.

Spread generously over the cooled cake.

Do not overwhip, or the cream may become grainy.

Keto Cream Cheese Frosting

Ingredients

8 ounces softened cream cheese

¼ cup softened butter

½ cup powdered erythritol

1 teaspoon vanilla extract

2 tablespoons heavy cream

Beat until smooth and fluffy.

Spread evenly over the cooled cake.

Refrigerate for 20 minutes before serving for easier slicing.

Chocolate Variation

Replace two tablespoons of almond flour with unsweetened cocoa powder.

Add sugar-free chocolate chips.

Finish with chocolate whipped cream.

Dust lightly with cocoa powder before serving.

Lemon Variation

Increase the lemon zest to two teaspoons.

Add one tablespoon of fresh lemon juice.

Finish with lemon whipped cream.

Decorate with thin lemon slices.

Almond Variation

Increase almond extract slightly.

Top with sliced toasted almonds.

Serve with whipped cream.

Berry Version

Top each slice with fresh raspberries, strawberries, or blueberries.

The berries add freshness while keeping the carbohydrate count relatively low when served in moderation.

Serving Suggestions

Serve slightly chilled.

Pair with freshly brewed coffee.

Enjoy alongside hot tea.

Serve with keto ice cream.

Top with toasted coconut flakes.

Drizzle with sugar-free chocolate sauce.

Add chopped roasted pecans.

Dust lightly with powdered keto sweetener.

Expert Tips for Success

Always use finely ground almond flour.

Measure ingredients accurately.

Separate eggs carefully.

Use room-temperature ingredients.

Whip egg whites until stiff peaks.

Fold gently without stirring.

Never overmix the batter.

Bake in the center of the oven.

Avoid opening the oven door during the first 30 minutes.

Cool completely before frosting.

Store leftovers properly to preserve moisture.

Common Mistakes to Avoid

Using coarse almond meal instead of fine almond flour.

Adding too much coconut flour.

Overbeating the egg whites until dry.

Deflating the batter while folding.

Using cold ingredients.

Skipping parchment paper.

Removing the cake too early from the oven.

Cutting the cake while still warm.

Adding liquid sweeteners that alter the batter consistency.

Overbaking, which can dry out the cake.

Storage Instructions

Store the cake in an airtight container in the refrigerator for up to five days. Allow slices to sit at room temperature for about 20 minutes before serving for the softest texture.

Freezing Instructions

Wrap individual slices tightly in plastic wrap and then in aluminum foil or place them in freezer-safe containers. Freeze for up to three months. Thaw overnight in the refrigerator before serving.
