Diplomat Cream Recipe (Crème Diplomate)

Quick Summary: Diplomat cream (crème diplomate) is a light, luscious French filling made by folding whipped cream into gelatin-stabilized vanilla pastry cream. It comes together in about 40 minutes plus chilling time and pipes beautifully into cakes, tarts, choux pastries, and layered desserts.

Making one of the most delicious French creams, the Diplomat cream is a part of the prestigious CAP Pâtissier program in France, as well as other esteemed culinary schools.

What is Diplomat cream?

Diplomat cream, also called Crème Diplomate in French, is a basic French cream filling made with French pastry cream (crème pâtissière), gelatin, and whipped cream.

You may also hear other names, such as whipped pastry cream, pastry cream with whipped cream, or whipped pastry cream, which all mean the same thing: Diplomat cream.

But don't confuse Crème Diplomate with Crème Madame:

• Creme Diplomate has gelatine added to the party cream or Creme Pat, for extra stability and firmness.
• Creme Madame has no added gelatine, making it lighter than Diplomat cream.

Why you'll love this recipe

• It is easy and quick. This vanilla diplomat cream comes together from simple components without any special skills required.
• It uses a few simple ingredients. The cream is built on pastry cream and whipped cream, with the option to add your favorite flavors.
• It is light yet stable. Folding whipped cream into the pastry cream gives a smooth, airy filling, while a touch of gelatin helps it hold its shape.
• It is the best filling for pastries. Use it in a mille-feuille, tarts, and choux pastry such as eclairs and cream puffs.
• It is versatile for cakes. It works beautifully as a filling and garnish for layer cakes, fruit cakes, and number cakes.

Ingredients

For ingredients and detailed instructions, refer to the recipe card below.

• Milk: The pastry cream recipe calls for whole milk. To make it lighter, replace it with low-fat or semi-skimmed milk, but avoid skim milk.

Use half of the milk and half of the heavy cream for a richer version. To vary, or for a dairy-free version, you can replace some or all of the milk with coconut or other plant-based milk (unflavored).

• Vanilla bean or gousse de vanille brings a beautiful flavor to the vanilla pastry cream and the finished product, Diplomat cream. Alternatively, you can use vanilla extract (extrait de vanille) or vanilla paste.

• Sugar: The recipe calls for granulated or caster sugar.

• Cornstarch acts as a thickener in creme patissiere. You can replace it with all-purpose flour, the same as plain flour in the UK, to achieve a firmer cream texture.

You can also use potato starch or a 1:1 mix of flour and cornstarch. The custard cream made with only cornstarch has a lighter texture, though.

• Eggs provide the flavor and structure of the pastry cream. Use either egg yolks or jaunes d'oeufs, or replace them with whole large eggs to make the cream lighter. Make sure to bring eggs to room temperature.

• Gelatin sheets or feuilles de gélatine are used to stabilize creme Diplomate. You can use powdered gelatin if desired. The thickness of the final cream depends on the amount of gelatin used.

You can replace gelatin with agar-agar, using 3 times as much agar-agar as gelatin. To activate the agar-agar's gelling action, add it to the milk and bring it to a boil for 1 minute. Then proceed with the recipe.

• Heavy cream is an essential ingredient in the recipe. Opt for "heavy cream" or "heavy whipping cream" with at least 30% fat content. If you live in the UK, use double cream.

If you want to use a dairy-free cream alternative, ensure it contains enough fat to whip.

How to make French Diplomat cream

The key to the success of Diplomat Cream is to respect the ingredient order, cream-making steps, and chilling time. Creme Diplomate is made in three simple steps:

1. Making French pastry cream;
2. Making whipped cream;
3. Incorporation of the whipped cream into the pastry cream.

Step 1: To make French pastry cream, place the gelatine sheets in a large bowl with cold water (grand bol d'eau froide) for 10 minutes.

Step 2: In a mixing bowl, whisk egg yolks with icing (powdered) sugar with a hand whisk until whitish. Then add cornstarch and whisk again.

Step 3: Split the vanilla pod lengthwise and scrape the seeds with a knife. Pour milk into a heavy-bottomed saucepan and add the vanilla pod, split in half, and vanilla bean seeds. Bring it to a boil over medium-high heat. Cover the saucepan with a lid and leave it to infuse for about 20-30 minutes if time permits. 

Expert tip: Consult the French pastry cream recipe for step-by-step, photographed explanations, helpful tips, and tricks.

Step 4: Pour the hot milk mixture over the egg yolk/sugar mixture, stirring vigorously with the whisk. Pour everything back into the saucepan and cook over low heat, stirring constantly, until the cream thickens (30 seconds to a minute). Don't stop stirring while cooking the cream to prevent it from sticking to the bottom of the pan.

Step 5: Pour the pastry cream into a shallow dish and remove the vanilla pod. If you see cream lumps, pass the cream through a fine-mesh sieve or use an immersion blender. Otherwise, omit this step.

Step 6: Add the softened and well-drained gelatin and mix well (photo 2). Gelatin must be added to the pastry cream while it is off the heat.

Step 7: Cover the dish with plastic film or film alimentaire on contact. The film must touch the surface of the cream to prevent skin formation. Leave it to cool to room temperature without refrigerating it.

Attention: Some recipes recommend chilling the pastry cream for 2-3 hours, or overnight, as a make-ahead option. Prolonged chilling of the pastry cream results in a strong gelatin set, making the cream too thick and difficult to work with.

Step 8: To make whipped cream, place the bowl of a stand mixer fitted with the whisk attachment in the freezer for 10 minutes. Remove the chilled bowl and beater from the freezer, then pour very cold cream into the bowl.

Expert tip: Consult the whipped cream recipe for step-by-step, photographed explanations, helpful tips, and tricks.

Step 9: Whip at medium speed until soft peaks form. You can use an electric hand mixer if desired.

Expert tip: The goal is to incorporate air into the whipped cream without reaching stiff peaks. Try to avoid whipping the cream at high speed.

Step 10: To make creme Diplomate, pass the pastry cream through a fine-mesh sieve for a smoother, finer cream; this is optional. Transfer the pastry cream to a clean mixing bowl and whip it for a few moments.

Step 11: Gently fold ⅓ of the whipped cream into the pastry cream with a rubber spatula. Then add the remaining whipped cream and gently mix, working in the same direction and lifting the cream from the bottom of the bowl.

Transfer the ready Diplomat cream to a pastry bag with a decorating tip and use it immediately. Or keep it in a closed piping bag in the refrigerator. 

Expert Tips

1. To prevent the milk from sticking to the bottom of the saucepan, add a bit of sugar to the empty pan, then pour the milk.
2. Cook the pastry cream over low heat, stirring constantly to prevent burning.
3. Using the gelatine powder, follow the package instructions for the amount of water needed and the time required to bloom. Then, add the gelatin mixture to the warm pastry cream.
4. Cover the cream with plastic wrap, keeping it in contact to prevent skin from forming on its surface.
5. If the final cream seems soft, refrigerate it for 1-2 hours before using.

Flavor variations

How to get creative with Diplomat Cream? You can play with pastry cream flavors by adding some ingredients. Let's try some unique flavor variations to find your signature recipe.

• Infuse milk: You can infuse the milk with flavors other than vanilla. For example, use star anise, cinnamon sticks (for making cinnamon Diplomat cream), mint, basil, tea, coffee beans (to make coffee Diplomat cream), or citrus zest. Let the boiled milk, covered with a lid, stay out of the heat for about 30 minutes. Then pass it through a fine-mesh sieve and continue with the recipe.

• Add chocolate: To make chocolate Diplomat cream, use dark chocolate, about 10% of the weight of the pastry cream ingredients (not counting the heavy cream). Break the chocolate into small pieces and add it to the hot pastry cream out of the heat and mix it. Then add gelatin and mix well again.

• Add alcohol: If you want to flavor your cream with alcohol, add dark rum, Grand Marnier, or another liquor, about 8% of the final pastry cream's weight. Remove the pastry cream from the heat, then add the alcohol before adding the whipped cream.

• Add fruit puree: You can incorporate a fruit puree of your choice, pistachio, or hazelnut paste, about 8% of the weight of the final pastry cream. Add puree or nut paste before adding the whipped cream.

• Add butter: Some pastry chefs add unsalted butter to the pastry cream for a richer, more gourmet flavor. The final cream will become richer if you add 1 oz. (30 g) of cold butter before adding the gelatin (out of the heat). But if you want to make light Diplomat cream, stick with the present recipe.

Storing & freezing

Due to its dairy nature, the cream is fragile and should not be kept at room temperature (not above 68°F or 20°C) for more than 30 minutes.

However, you can store the Diplomate cream in an airtight container in the refrigerator for up to 48 hours.

Can you freeze creme Diplomate? Unfortunately, it doesn't freeze well, but you can freeze cakes, cupcakes, or choux pastries filled with Diplomat cream. If used in desserts, you can freeze the desserts for up to 1 month.

Can you make diplomat cream ahead of time?

Yes, diplomat cream is well-suited to making ahead, which is why it is a favorite for filling pastries in advance. Because it is set with a little gelatin, it holds its shape once chilled, so plan around a couple of simple points.

• Prepare it a day ahead. Make the diplomat cream up to 24 hours before you need it and keep it covered in the fridge until you are ready to fill or pipe.
• Fill pastries close to serving. Pipe the cream into eclairs, cream puffs, or a tart shortly before serving so the pastry stays crisp and does not soften.
• Do not freeze it. Freezing breaks the delicate emulsion, causing the cream to separate and weep once thawed, so it is best enjoyed fresh.

How to use crème Diplomate

With vanilla Diplomat Cream, the dessert options become endless, from fluffy cakes and cupcakes to creamy pies and tarts. It is used to

• garnish a "number cake"
• fill and decorate a layered sponge cake and cupcakes
• garnish Mille-feuille and tarte Tropezienne
• fill choux pastry desserts such as chouquettes, choux à la crème, éclairs
• make a verine dessert with fresh fruit or fresh fruit tarts
• use it instead of the crème mousseline or whipped chocolate ganache

Troubleshooting tips

1. Pastry cream is too runny

Reason: The pastry cream isn't cooked enough.
Solution: Bring your pastry cream to a low simmer for 1-2 minutes, stirring constantly until the desired consistency.

2. Pastry cream is too thick (before adding gelatin)

Reason: The pastry cream is overcooked.
Solution: Add cold milk gradually to thin out the cream, mixing and checking for the right consistency.

3. Pastry cream is gelled

Reason: The pastry cream was cooled for too long after the gelatin had set, and the cream now looks "stuck."
Solution: Bring the pastry cream for 30 seconds in the microwave at 50% power, then give it a whiplash.

4. Pastry cream is lumpy

Reason: You either poured the hot milk into the egg mixture quickly or stirred the cream irregularly.
Solution: Pass the pastry cream through a fine-mesh strainer, or use an immersion blender with caution; it may turn the cream into liquid.

5. Heavy cream doesn't reach soft peaks

Reason: You probably used the liquid cream with a fat content of less than 30%, or the cream isn't cold enough for whipping.
Solution: If the cream has the right fat content (at least 30%), bring it to the freezer for 10-15 minutes, then whip it.

6. Heavy cream is too thick

Reason: The cream is probably overwhipped or has reached the stage of stiff peaks.
Solution: At this stage, it is impossible to save the cream, so whip another batch of cream to finish the Diplomat cream. Next time, watch the whipped cream closely for consistency, and stop the mixer at soft peaks.

7. Unable to fold in cream with pastry cream

Reason: You either have issues with pastry cream (too runny, too thick, or lumpy) or whipped cream (too thin or too thick).
Solution: To find the answer to why your pastry cream is not as desired, consult the troubleshooting section of the French pastry cream recipe.
For questions about making whipped cream or troubleshooting, refer to the sugar-free whipped cream recipe.

8. Diplomat cream is too soft

Reason: You either omitted gelatin or added less gelatin than required.
Solution: Place the bowl with the cream, covered with plastic wrap, in the refrigerator for 1-2 hours to thicken. Next time, try adding more gelatin to make the Diplomat cream firmer.

9. Diplomat cream is too thick

Reason: You might use too much gelatin, too much cream, or whipped cream until medium-high peaks form.
Solution: Unfortunately, at this stage, you cannot change the consistency of the final cream. Next time, check the amount of gelatin and heavy cream used in the recipe. Also, make sure to whip up the cream until it forms soft peaks.

In the end, you can control the fluffiness of the Diplomat cream by the amount of cream, and its firmness by the amount of gelatine.
