Ingredients Spotlight

• Almond Flour: The backbone of this cake, almond flour keeps it low-carb while adding a subtle nutty flavor. For best results, use finely ground blanched almond flour.
  Substitution: Coconut flour can work, but use only ¼–⅓ the amount and increase liquid slightly.
• Eggs (Separated): The whipped egg whites are what give this cake its signature cloud-like texture. Don’t skip the separation—it makes all the difference.
• Erythritol or Stevia: These sweeteners keep the cake keto-friendly without affecting blood sugar. Adjust to taste, especially if you prefer a milder sweetness.
• Heavy Cream: Adds moisture and richness while keeping the crumb tender.
  Dairy-free option: Full-fat coconut cream works beautifully.
• Vanilla Extract: Enhances the overall flavor and adds warmth. Almond extract can be used for a more nut-forward profile.

3 Expert Secrets for the Perfect Keto Cloud Cake

Whip the Egg Whites at Room Temperature

Cold egg whites take longer to whip and don’t reach the same volume. Let them sit at room temperature for 15–20 minutes before beating to achieve stronger, more stable peaks.

Fold, Don’t Stir

When combining the whipped egg whites with the batter, use slow, deliberate folding motions. Stirring aggressively will knock out the air you worked so hard to build, resulting in a denser cake.

Cool Completely Before Slicing

This cake continues to set as it cools. Cutting too early can cause it to collapse slightly in the center. Patience pays off with clean slices and a better final texture.

Step-by-Step Instructions

1. Preheat and Prepare
   Preheat your oven to 350°F (175°C). Line a round cake pan or springform pan with parchment paper to prevent sticking.
2. Separate the Eggs
   Carefully separate the egg whites from the yolks. Place the whites in a clean, dry mixing bowl—this is essential for proper whipping.
3. Mix the Wet Ingredients
   In a separate bowl, whisk together the egg yolks, heavy cream, vanilla extract, and sweetener until smooth and well combined.
4. Combine the Dry Ingredients
   In another bowl, sift together the almond flour, baking powder, and salt to ensure an even texture.
5. Whip the Egg Whites
   Using a hand mixer or stand mixer, beat the egg whites until stiff peaks form. They should hold their shape when the beater is lifted.
6. Fold Gently
   Slowly fold the yolk mixture into the whipped egg whites using gentle, sweeping motions. Take care not to deflate the mixture.
7. Incorporate the Dry Ingredients
   Gradually sift the dry ingredients into the batter, folding gently until just combined. Avoid overmixing.
8. Bake the Cake
   Pour the batter into the prepared pan and smooth the top. Bake for 25–30 minutes, until lightly golden and a toothpick inserted in the center comes out clean.
9. Cool and Serve
   Allow the cake to cool completely in the pan before slicing. This helps the structure set and preserves the airy texture.

Serving Ideas

This cake shines on its own, but it’s also incredibly versatile:

• Serve with coffee or tea for a light afternoon treat
• Use it as a base for keto strawberry shortcake
• Dust lightly with powdered erythritol for a classic finish

Optional Add-Ins & Variations

• Keto chocolate chips for a dessert-style twist
• Fresh berries like raspberries or strawberries for contrast
• Homemade whipped cream for extra indulgence

Storing the Cake:

Once completely cooled, store the cake in an airtight container. It can be kept at room temperature for up to 2–3 days if your kitchen is cool and dry. For longer freshness, refrigerate the cake for up to 7 days. Chilling helps preserve the texture, especially if the cake is topped with whipped cream or fruit.

Freezing Instructions:

This cake freezes surprisingly well. Wrap individual slices tightly in plastic wrap, then place them in a freezer-safe container or bag. Freeze for up to 2 months. Thaw overnight in the refrigerator or let sit at room temperature for about 30 minutes before serving.

Reheating Tips:

If you prefer your cake slightly warm, microwave individual slices for 15–20 seconds. Avoid overheating, as it can dry out the cake. For a more even warmth, place slices in a low-temperature oven (300°F / 150°C) for a few minutes. Handled gently, your Keto Cloud Cake will stay just as fluffy and satisfying as the day it was baked.

Absolutely. I’ve found that this cake is actually even better the next day. Once it’s fully cooled, just store it in the fridge in an airtight container. The texture holds up beautifully, and the flavors have time to really come together.

Frequently Asked Questions

Can I make Keto Cloud Cake ahead of time?

Absolutely. I’ve found that this cake is actually even better the next day. Once it’s fully cooled, just store it in the fridge in an airtight container. The texture holds up beautifully, and the flavors have time to really come together.

Can I use coconut flour instead of almond flour?

Yes, but with a little caution. Coconut flour is much more absorbent. My secret for this is using only about ¼ to ⅓ of the amount and adding a bit more liquid. The texture will be slightly different, but still delicious.

Why did my cake turn out flat?

This usually comes down to the egg whites. I’ve found that if they aren’t whipped to stiff peaks—or if they get overmixed when folding—the cake can lose its lift. Take your time with this step and fold gently.

Can I freeze Keto Cloud Cake?

You’re going to love how freezer-friendly this cake is. I slice it, wrap each piece tightly, and freeze for up to two months. When I want a slice, I just let it thaw at room temperature or in the fridge overnight.

Is this cake sweet enough for non-keto eaters?

In my experience, yes. I’ve served this to plenty of people who don’t follow keto, and no one has ever guessed it was low-carb. If you prefer a slightly sweeter cake, you can always add a touch more sweetener to suit your taste. Beat the egg whites until stiff peaks form.
