Caramel Cloud Cake — Ultra-Fluffy Layer Cake

The first bite is airy and melting, with warm caramel notes that linger on the tongue. This Caramel Cloud Cake balances a pillowy sponge with a glossy, barely-thick caramel glaze for a dessert that feels fancy but is surprisingly simple to make. After testing this recipe 8 times with different mixers and pans, I settled on the technique below to keep the cake tall and soft while avoiding a gummy crumb. I developed this version during weekend recipe trials at home and refined the caramel so it sets shiny without becoming brittle. If you love caramel desserts, you might also enjoy our salted caramel pretzel for a crunchy contrast to this cake. Read on for ingredient science, clear steps with metric and imperial measures, and pro tips to get it right the first time.

Why This Recipe Works

Egg-whites folded into whipped yolk batter create a very light, stable sponge without heavy dairy.
Creamy caramel is reduced to the right thickness so it glazes the cake but doesn’t harden into candy.
Room-temperature ingredients incorporate more evenly, giving a tender crumb and uniform lift.
Baking in the recommended pan size prevents a collapsed center by leaving room for the cake to rise.
Brief cooling on a wire rack stops steam from making the glaze runny, preserving shine and texture.

Ingredients Breakdown

All-purpose flour — 250 g (2 cups). Provides structure. Weigh for best results; spoon and level if using cups.
Granulated sugar — 220 g (1 cup) plus 60 g (¼ cup) for the caramel. Sugar sweetens and helps the sponge brown.
Eggs — 5 large, separated. Whites whipped to stiff peaks give lift; yolks add richness and color.
Whole milk — 240 ml (1 cup), warmed to 35–40°C (95–105°F). Warmer milk helps dissolve sugar and bloom the batter.
Unsalted butter — 113 g (½ cup), melted and cooled. Adds tenderness and mouthfeel.
Baking powder — 10 g (2 tsp). Light leavening for a gentle rise.
Fine sea salt — 3 g (½ tsp). Balances sweetness. Use Diamond Crystal by volume; if using Morton’s, halve the amount.
Vanilla extract — 10 ml (2 tsp). Enhances caramel notes.
Heavy cream — 120 ml (½ cup) for the caramel. Creates a soft, pourable glaze.
Water — 30 ml (2 tbsp) for the caramel. Helps dissolve sugar while cooking.
Substitutions with impact warnings: You can swap 250 g (2 cups) all-purpose flour for a 1:1 gluten-free blend, but the crumb will be slightly denser and may need 1 extra egg white for lift. Replacing butter with neutral oil yields a moister cake with less buttery flavor.

Essential Equipment

9-inch (23 cm) round cake pans, two layers — do not use 8-inch pans; batter volume requires a 9-inch pan to avoid overflow.
Digital scale — for accurate weighing of dry ingredients.
Stand mixer or electric hand mixer — for whipping egg whites to stiff peaks.
Rubber spatula — for gentle folding.
Candy thermometer — helpful for checking caramel temperature (optional).
Wire rack — to cool cakes and set glaze.
Parchment paper — to line pans for easy release.
If you don’t have two 9-inch pans, bake in one pan and slice the cake horizontally once cooled for layers.

Step 1: Recipe Timing and Servings

Prep Time 30 minutes; Cook Time 25 minutes; Inactive Time 1 hour (cooling); Total Time about 1 hour 55 minutes; Serves 8 slices.

Step 2: Preheat and Prep Pans

Preheat the oven to 175°C (350°F). Line and butter two 9-inch (23 cm) pans, and dust lightly with flour. Give yourself 10 minutes for this prep.

Step 3: Sift Dry Ingredients

Whisk together 250 g (2 cups) all-purpose flour, 10 g (2 tsp) baking powder, and 3 g (½ tsp) salt in a bowl. Set aside for 2 minutes. This ensures even leavening and removes lumps.

Step 4: Make the Yolk Batter

In a clean bowl, whisk 5 large egg yolks with 220 g (1 cup) granulated sugar until pale and slightly thick, about 2–3 minutes by hand or 1 minute with a mixer. Add 240 ml (1 cup) warm whole milk, 113 g (½ cup) melted butter, and 10 ml (2 tsp) vanilla; whisk until combined. Fold in the dry ingredients gently until no streaks of flour remain, about 20–30 seconds. Do not overmix — stop as soon as no dry flour is visible.

Step 5: Whip Egg Whites

In a separate bowl, beat 5 large egg whites until soft peaks form, about 2–3 minutes with a stand mixer on medium. Gradually add 30 g (2 tbsp) granulated sugar and continue beating to firm, glossy peaks, about 2 more minutes. The peaks should stand but bend slightly at the tip.

Step 6: Fold Whites into Batter

Fold one-third of the whipped whites into the yolk batter to loosen it, about 15 seconds. Gently fold in the remaining whites in two additions, using a rubber spatula and lifting from the bottom, turning the bowl. Fold until streaks disappear — about 10–15 folds. Be gentle to keep the batter airy.

Step 7: Bake

Divide batter evenly between the two prepared pans. Smooth tops and tap the pans once on the counter to release large air pockets. Bake at 175°C (350°F) for 20–25 minutes, rotating pans at 12 minutes for even browning. Cakes are done when golden and a toothpick inserted near the center comes out with a few moist crumbs, or an instant-read thermometer reads 93°C (200°F).

Step 8: Cool

Let cakes cool in pans for 10 minutes, then invert onto a wire rack. Cool completely, about 45–60 minutes, before glazing. Cooling fully prevents the glaze from sliding off.

Step 9: Make the Caramel Glaze

Combine 60 g (¼ cup) granulated sugar and 30 ml (2 tbsp) water in a heavy-bottomed saucepan. Cook over medium heat without stirring, swirling the pan occasionally, until the mixture turns a deep amber, about 6–8 minutes. Remove from heat and carefully whisk in 120 ml (½ cup) heavy cream and 15 g (1 tbsp) unsalted butter; the mixture will bubble vigorously. Stir until smooth. If you have a candy thermometer, target 118–121°C (245–250°F) for a pourable glaze. Cool to about 40–45°C (104–113°F) before pouring.

Step 10: Glaze and Assemble

Place one cake layer on a serving plate. Pour a few tablespoons of caramel to soak the top, then set the second layer on top. Pour remaining caramel over the center and tilt the cake to let it drip naturally down the sides. Allow glaze to set for 30 minutes at room temperature before slicing.

Expert Tips & Pro Techniques

For the lightest crumb, use room-temperature eggs; they whip better and incorporate air more easily.
Avoid adding sugar to whites until soft peaks form; adding too early can weigh them down.
Common mistake: overfolding egg whites. Stop when streaks disappear — the batter will still have tiny air bubbles.
Make-ahead: Bake layers up to 24 hours ahead. Wrap tightly in plastic wrap and keep at room temperature. Glaze just before serving.
Professional trick adapted for home kitchens: Warm the cake layers for 10 seconds in the microwave (at low power) before glazing to help the caramel adhere evenly. Do not overheat.
If your caramel crystallizes while cooking, add 1 tsp of lemon juice or a few drops of cream to re-smooth it on low heat.

Storage & Reheating

Refrigerator: Store glazed cake in an airtight container or under a cake dome for up to 3 days. The glaze will soften over time but remain flavorful.
Freezer: The unglazed, wrapped layers freeze well for up to 2 months. Thaw in the refrigerator overnight, then bring to room temperature before glazing. Do not freeze glazed cake — the glaze becomes grainy on thawing.
Reheating: Warm single slices in a 150°C (300°F) oven for 6–8 minutes to slightly revive texture. Avoid microwaving — it makes the sponge gummy.

Variations & Substitutions

Salted Caramel Version: Add ¼ tsp flaky sea salt to the caramel and sprinkle a little on top after glazing. Everything else stays the same.
Coconut-Caramel Twist: Replace 60 ml (¼ cup) heavy cream in the caramel with 60 ml (¼ cup) coconut cream. Keep baking times unchanged; expect a subtle coconut aroma.
Egg-Free Option: Use 250 g (2 cups) self-raising flour, 240 ml (1 cup) whole milk, 60 ml (¼ cup) neutral oil, and 1 tsp baking powder plus 1 tsp baking soda as a trial. Results will be denser; consider adding 1 tsp apple cider vinegar to the milk to help lift.
Mini Layer Cakes: Bake batter in three 6-inch pans; reduce bake time to 14–18 minutes. Stack as usual.

Frequently Asked Questions

Q: Why did my cake turn out dense instead of fluffy?
A: Most often this comes from overmixing after adding flour or deflating the egg whites by folding too vigorously. Fold gently and stop when streaks of batter disappear.

Q: Can I make this without eggs?
A: You can try an egg-free version, but expect a denser crumb. See the egg-free option in Variations for suggested swaps and notes.

Q: Can I double this recipe to feed a crowd?
A: Yes. Use two 9-inch pans for each batch size, or bake in larger pans and adjust bake time. Make sure not to crowd the oven; bake in batches if needed.

Q: Can I prepare this the night before serving?
A: Yes. Bake the layers and wrap them; glaze the next day for the best texture. Store layers at room temperature for up to 24 hours.

Q: How long does this cake keep in the fridge?
A: Glazed cake keeps for up to 3 days in the refrigerator in an airtight container. Unfrosted layers last about 2 days at room temperature or up to 2 months in the freezer.

Q: My caramel hardened and won’t pour — what happened?
A: The caramel likely cooked too long or cooled too much. Warm gently over low heat and stir in 1 tsp warm cream to smooth it. Avoid overheating.

Q: Can I use brown sugar in the sponge?
A: Replacing some granulated sugar with brown sugar will add moisture and a deeper caramel flavor but may slightly darken the crumb. Try replacing up to 50 g (¼ cup) and test texture.
