Ingredients

6 large eggs, separated carefully

4 ounces cream cheese, softened to room temperature

¼ cup unsalted butter, softened

¾ cup powdered keto sweetener such as erythritol or monk fruit blend

1 teaspoon vanilla extract

½ teaspoon almond extract (optional)

½ teaspoon cream of tartar

1 teaspoon baking powder

¼ teaspoon salt

2 tablespoons coconut flour

½ cup finely ground almond flour

2 tablespoons heavy whipping cream

For the optional whipped topping:

1 cup heavy whipping cream

2 tablespoons powdered keto sweetener

1 teaspoon vanilla extract

Optional garnish:

Fresh raspberries

Fresh strawberries, sliced

Unsweetened toasted coconut flakes

Sugar-free dark chocolate shavings

Lemon zest

Powdered keto sweetener for dusting

Equipment Needed

Two large mixing bowls

Electric hand mixer or stand mixer

Rubber spatula

Fine mesh sieve

Measuring cups and spoons

8-inch round cake pan

Parchment paper

Cooling rack

Offset spatula if frosting

Preparing the Cake Pan

Preheat the oven to 325°F (163°C).

Grease the cake pan lightly with butter.

Line the bottom with parchment paper.

Lightly grease the parchment.

This preparation helps the delicate cake release easily after baking.

Preparing the Egg Yolks

Separate the eggs carefully, ensuring no yolk enters the whites.

Place the yolks into a large mixing bowl.

Add softened cream cheese.

Add softened butter.

Beat until smooth and creamy.

Mix in the powdered sweetener gradually.

Continue beating until light and fluffy.

Add vanilla extract.

If using almond extract, mix it in now.

Add heavy cream.

Mix until completely smooth.

Sift together almond flour, coconut flour, baking powder, and salt.

Slowly add the dry ingredients into the cream cheese mixture.

Mix just until fully incorporated.

Do not overmix.

The batter should be thick, creamy, and completely smooth.

Whipping the Egg Whites

Place the egg whites into a completely clean mixing bowl.

Add cream of tartar.

Beat on medium speed until foamy.

Increase to high speed.

Continue whipping until stiff glossy peaks form.

The egg whites should hold their shape firmly when the beaters are lifted.

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

Folding the Batter

Add one-third of the whipped egg whites into the yolk mixture.

Stir gently to lighten the batter.

Fold in the remaining egg whites in two additions.

Use a rubber spatula.

Fold gently from the bottom upward.

Rotate the bowl after every few folds.

Continue only until no white streaks remain.

The batter should remain light, fluffy, and airy.

Overmixing will remove the trapped air and reduce the cake’s height.

Filling the Pan

Transfer the batter into the prepared cake pan.

Spread evenly using an offset spatula.

Tap the pan once very gently to remove only large air pockets.

Avoid excessive tapping.

Smooth the surface.

Baking Instructions

Bake in the preheated oven for 35 to 40 minutes.

The top should become lightly golden.

The center should spring back when touched gently.

A toothpick inserted into the center should come out mostly clean.

Avoid opening the oven during the first 30 minutes of baking.

Sudden temperature changes may cause the cake to collapse.

Cooling the Cake

Remove the cake from the oven.

Allow it to cool in the pan for about 15 minutes.

Run a thin knife around the edges.

Carefully remove from the pan.

Transfer to a cooling rack.

Allow the cake to cool completely before frosting or slicing.

Cooling completely helps the structure stabilize.

Preparing the Whipped Topping

Pour chilled heavy cream into a cold mixing bowl.

Add powdered keto sweetener.

Add vanilla extract.

Whip until medium peaks form.

Do not overwhip.

Spread generously over the cooled cake.

Optional Cream Cheese Frosting

For a richer dessert, prepare a keto cream cheese frosting.

Beat together:

8 ounces softened cream cheese

¼ cup softened butter

½ cup powdered keto sweetener

1 teaspoon vanilla extract

2 tablespoons heavy cream

Beat until smooth and fluffy.

Spread evenly over the cooled cake.

Serving Suggestions

Top each slice with fresh raspberries.

Add sliced strawberries for natural sweetness.

Sprinkle with toasted coconut flakes.

Decorate with sugar-free chocolate curls.

Pair with freshly brewed coffee.

Serve alongside hot tea.

Enjoy with iced coffee during warm weather.

Add a few chopped toasted pecans for extra crunch.

Flavor Variations

Use orange extract instead of almond extract.

Add finely chopped toasted pecans.

Mix in sugar-free chocolate chips.

Swirl keto peanut butter into the batter.

Make cupcakes by dividing the batter into muffin tins.

Turn the cake into a layered celebration cake.

Expert Tips

Always use room-temperature ingredients.

Separate eggs while cold, then allow them to reach room temperature.

Clean bowls thoroughly before whipping egg whites.

Even tiny amounts of grease can prevent proper whipping.

Measure coconut flour carefully since it absorbs significant moisture.

Fold slowly to preserve air bubbles.

Avoid overbaking.

Cool completely before slicing.

Store leftovers chilled.

For the softest texture, allow refrigerated slices to sit at room temperature for 15 minutes before serving.

Storage

Store the cake in an airtight container in the refrigerator for up to five days.

For longer storage, wrap individual slices tightly in plastic wrap and place them in a freezer-safe container. Freeze for up to two months.

Thaw overnight in the refrigerator before serving.

Avoid repeated freezing and thawing, as this may affect the delicate texture.

Frequently Asked Questions

Why is my cake dense instead of fluffy?

The egg whites may have been overmixed into the batter or not whipped to stiff peaks. Gentle folding is essential to maintain the airy texture.

Can I make this cake dairy-free?

This recipe depends heavily on cream cheese and butter for structure and flavor, so dairy-free substitutions may significantly change the final result.

Can I use only almond flour?

A small amount of coconut flour helps absorb moisture and improves texture. Replacing it entirely with almond flour may produce a softer, less stable cake.

Why did my cake collapse after baking?

Minor settling is normal, but excessive collapse usually happens from underbaking, opening the oven too early, or overmixing the egg whites.

Can I prepare this cake ahead of time?

Yes. It actually tastes even better after chilling for several hours, allowing the flavors to develop and the texture to become even more tender.
