What is creme patissiere (pastry cream), and what is it used for?

Creme Patissiere is crème anglaise, a vanilla sauce thickened with egg yolks (or eggs) and cornstarch into a considerable body used for all-purpose desserts like cake fillings, and for other fillings such as tarts (like this Torta Della Nonna), fruit tarts (like this Tarte Aux Fraises), choux pastry, Cruffins, donuts (like these Boston cream pie donuts), Pavlova, and other many more.

It is made by cooking eggs, milk, sugar, and cornstarch over direct heat and flavoring it with vanilla essence. But countless flavor options can be added while warm.

Sometimes the cream is folded into Almond Cream Filling to make a classic Frangipane.

Key ingredients

We only need simple ingredients to make this delicious creamy vanilla custard and the perfect filling. Note that these basic ingredients are key for a successful recipe.

Ingredients to make pastry cream


Eggs are rich in proteins, and when exposed to heat, the proteins tend to stretch and bond with each other into a weaving structure. In our case, the liquid is trapped between the gaps of the weave structure.

Egg whites are richer in protein than egg yolks, while egg yolks are rich in fat, contributing to the creamy texture of any classic pastry cream. 

One egg can thicken 1/2 cup of liquids; into a self-standing custard, but in our case, since we are using one cup per egg, the custard gets a thinner texture.

In this recipe, you can use two large whole eggs or one whole egg plus two egg yolks or four large egg yolks. It is a good idea to use room-temperature eggs.


Half and half is a mixture of cream and milk and can provide a creamy custard without the fear of it cuddling. 

You can use whole milk instead, but not cream. The cream might cause the creme to break and curdle. 

Corn starch

The cornstarch will absorb the liquids the eggs could not trap because of the large amount of half-and-half in the recipe. See how starches swell and thicken in my What Is Heavy Cream post. While all starches swell and thicken, some are thickened into a firmer structure, like potato starch, so avoid substituting.

Vanilla Flavor

This pastry cream recipe is flavored with vanilla bean paste for that classic vanilla pastry cream flavor. You can also use vanilla extract (add it with the butter) or a vanilla pod

Time needed: 20 minutes

Please read the step carefully before making the recipe.

  1. Prep

    To ensure the recipe’s success, preparation is crucial.
    To start, measure the necessary ingredients and whisk the eggs and cornstarch together in a bowl. Incorporate 1/4 cup of the half-and-half into the mixture, then set it aside. Keep a sieve handy nearby.
    Next, take a medium-sized saucepan and add the remaining half-and-half, vanilla, sugar, and salt to it.a pan and a bowl with ingredients to make custard

  2. Apply Heat 

    First, heat the half-and-half in a saucepan until it boils. Take four tablespoons of the boiling liquid and slowly pour it into the egg mixture, then strain it through a sieve and into a small bowl.

    Return the remaining half-and-half in the saucepan to a boil over medium heat, and then add the egg mixture.

    Continuously stir the mixture for 20-30 minutes, ensuring it reaches the bottom and sides of the pan. Once the cream has thickened or reached a temperature of 180F, please remove it from the heat and add in the butter, stirring until it has melted.

Flavoring classic crème pâtissière

This French pastry cream can be flavored with many different flavor and texture options; here are some ideas:

  • Coffee crème pâtissière. Add 1-2 teaspoons of instant coffee or espresso powder to the half-and-half.
  • Chocolate pastry cream. Add 1/3 cup chopped chocolate when warm and stir until smooth.
  • Peanut butter pastry cream. Stir 1/2 cup of smooth peanut butter into a hot pastry cream and stir until smooth.
  • Crème légère. Fold 2-3 cups of whipped heavy cream into a cold pastry creme. (creme diplomat, or diplomat cream, is the same but with an addition of relating for more stability). I used it to make these Choux a la creme.
  • Citrusy cream. Add some lemon or orange zest with the butter.
  • Creme Chiboust. Meringue lightened creme pat.
  • Creme Mousseline. Patissiere cream whipped with butter

Common pastry cream mistakes and FAQ

The pastry creme is too thick

You may have added too much cornstarch. Add some more liquid and cook while stirring.

The custard is too thin.

At first, it may seem a bit thin, and it thickens as it cools. If it is thick when warm, but then it is completely thin, it means that you did not cook it long enough. An enzyme called amelize tends to break the cornstarch if we don’t deactivate it by cooking it to 180F. 

The creme patissiere is grainy

​The eggs were not incorporated well, some were cooked and curdled, or the custard broke. Try to run it through a sieve and then whip it with an electric mixer.

Why is my creme gray?

Avoid using aluminum bowls, beaters, or saucepans. Aluminum discolors eggs into gray-greenish color. (and vice versa, eggs discolor aluminum dishes)

Can I use flour instead of cornstarch?

Yes, and cake flour is the best option.

Can I freeze crème pâtissière?

Yes, up to one month. If it seems to curdle, whip it with an electric mixer.
