Custard Powder And Egg Recipe: Fluffy Clouds With Crispy Celery Top

This custard powder and egg recipe transforms simple ingredients into a velvety dessert with a golden, crispy celery topping that looks like edible lace. The secret lies in balancing custard powder—whether store-bought or homemade—with eggs and milk to create a silky texture that sets perfectly while the celery crust achieves that signature crunch. I perfected this recipe after years of experimenting with custard desserts, and the difference between a dense, rubbery flan and this light, airy version is all in the technique.

The foundation starts with whisking eggs and custard powder until smooth, then slowly incorporating warm milk to prevent lumps. Baking at a precise 325°F ensures the custard sets evenly without curdling, while the celery topping gets its signature crispness from a high-heat finish. This vegetarian dish is elegant enough for brunch but simple enough for a weeknight dessert—just don’t skip the water bath, which guarantees a silky interior every time. The contrast between the creamy custard and the crispy top is what makes this recipe unforgettable.

What you’ll end up with is a dessert that looks like it belongs in a patisserie: a smooth, trembling custard center crowned with a delicate, shatteringly crisp celery lattice. The aroma of vanilla and warm milk fills the kitchen as it bakes, and the first bite delivers that perfect balance of textures—creamy, cool custard melting under the crispy top. This is the kind of dessert that makes you feel like a baking pro, even if you’ve never attempted custard before.

Perfect for special occasions or when you want to impress without fuss, this recipe scales beautifully for parties or individual servings. The custard powder can be adjusted to your preference—whether you use a commercial mix or make your own from flour and sugar—and the celery topping adds a sophisticated touch without complicating the process. Let’s get started on creating your own fluffy clouds with crispy tops.

Ingredients for custard powder and egg

Six simple ingredients transform into a showstopping dessert with crispy celery lace.

The custard powder is the heart of this recipe—whether you grab Betty Crocker or make your own from flour and sugar. King Arthur flour works best for homemade mixes, and I always double-check the expiration date since old powder can make custards gummy. For the eggs, farm-fresh from local markets have richer flavor, but store-bought works fine. Warm the milk to 160°F before mixing—it blends smoother and prevents lumps. The vanilla extract should be pure, not imitation, and Trader Joe's has a great affordable option. Butter matters here too—full-fat gives that luxurious mouthfeel you can't get with low-fat versions.

No custard powder? Make your own by mixing 1/4 cup flour, 1/4 cup sugar, and 1/4 tsp salt—it's the same ratio but gives you control. Short on eggs? Flax eggs (1 tbsp ground flaxseed + 3 tbsp water = 1 egg) work in a pinch, though texture will differ slightly. The celery topping needs thick stalks—avoid thin ones from the middle of the bunch. For the lattice, slice the celery at a 45-degree angle for that signature look. No vanilla? Almond extract at half the amount adds a nice twist. And if you're baking for a crowd, double the celery topping—it disappears fast!

This custard keeps beautifully—3-4 days in the fridge covered tightly. The celery lattice stays crisp for 2 days if stored in an airtight container. For parties, assemble it morning-of and bake just before serving. Freeze the custard portion (without topping) for up to 3 months—thaw overnight in the fridge. The celery topping can be baked ahead and reheated briefly in the oven to restore crispness. Always chill the custard completely before adding the topping—cold custard prevents soggy lattice

Step-by-step instructions for fluffy clouds with crispy celery top

Here's how to create silky-smooth custard with a golden, crispy celery lattice—it's easier than it looks!

In a large mixing bowl, combine the 4 whole Large Eggs and 1.5 cups Granulated Sugar. Using a hand mixer or whisk, beat on medium-high speed for 3-5 minutes until the mixture is pale, thick, and forms soft ribbons when the whisk is lifted. This step is crucial—it incorporates air, which creates that signature light, cloud-like texture.

I like to stop occasionally and scrape down the sides of the bowl with a spatula to ensure everything gets fully incorporated. The mixture should look almost like a thick, glossy meringue. If you're using room-temperature eggs, they'll blend more smoothly without any lumps.

In a separate saucepan, gently warm the 2 cups Whole Milk over medium heat until it reaches 160°F—just until small bubbles form around the edges but don't boil. This temperature ensures the milk is hot enough to blend smoothly but not so hot it cooks the eggs immediately when combined.

With the mixer running on low speed, slowly pour the warm milk into the egg mixture while whisking constantly. This gradual addition prevents the eggs from scrambling. Once fully combined, add the 0.5 cup Custard Powder and mix until completely dissolved. Then stir in the 1 tbsp Vanilla Extract and 0.25 cup Unsalted Butter. The mixture should be smooth and slightly thickened.

While the custard base cooks, prepare the celery lattice. Preheat your oven to 350°F. In a small bowl, mix together the 1 cup All-Purpose Flour, 0.5 tsp Baking Powder, 0.25 tsp Salt, and 0.25 cup Granulated Sugar. Cut the 1 bunch Celery Stalks into thin strips, about 1/8-inch thick, and toss them in the flour mixture until evenly coated.

Arrange the celery strips in a lattice pattern on a parchment-lined baking sheet, leaving a 1-inch border around the edges. Bake for 12-15 minutes until golden brown and crispy. Keep warm while you prepare the custard—it'll stay crispy for a few minutes.

Pour the custard mixture into a 9-inch round baking dish that fits inside a larger roasting pan. Carefully pour the 1 cup Water into the bottom of the roasting pan, then place the baking dish inside. This water bath creates gentle, even heat that prevents cracking while ensuring a silky texture.

Bake at 350°F for 45-50 minutes, until the custard is just set but still slightly wobbly in the center. You'll know it's ready when the edges are set and the center jiggles like gelatin. Remove from the water bath and let it cool to room temperature before refrigerating for at least 4 hours—this step is non-negotiable for that perfect, creamy texture.

Once fully chilled, carefully place the crispy celery lattice on top of the custard. The contrast of the warm, crunchy celery against the cool, creamy custard is what makes this dessert special. Serve individual portions by cutting through the lattice and custard together—each bite delivers that perfect balance of textures.

For an extra touch, dust the top with a little extra Granulated Sugar or a sprinkle of custard powder before serving. The custard should be smooth, velvety, and just sweet enough, while the celery lattice adds a delightful crunch that keeps every bite exciting.

Vanilla Bean Sauce

Elevate your custard dessert with a homemade vanilla bean sauce—simmer ½ cup heavy cream, 2 tbsp sugar, and 1 split vanilla bean for 10 minutes until thickened. Strain and drizzle over individual servings. The natural sweetness complements the custard’s richness without overpowering it. 🌿

Caramel Drizzle

For a luxurious finish, make a salted caramel drizzle by heating ½ cup sugar in a saucepan until melted, then adding ¼ cup heavy cream and 1 tbsp butter. Swirl it over the custard before serving.
