Microwave Pastry Cream: How To Make it Lump-Free

Sneak Preview: Yes. You can make a microwave pastry cream for your next pie or pudding in minutes. No worries about scorching. Lump-free texture!

Learn how to make a silky smooth microwave pastry cream or cream-pie filling in a microwave as good or better than making it on top of the stove. No worries about scorching, tempering eggs, lumps, etc.

Try it out for yourself with a tasty banana cream pie or a coconut cream pie.

Why use a microwave?

In only 7 minutes (or less), you can make the smoothest, tastiest cream-pie filling your taste buds have ever encountered.  Here’s why:

  • It’s faster. Cook one batch of pie filling in 7 minutes. Add 5 more to put the ingredients together.
  • No need for a double boiler
  • Constant stirring and babysitting are unnecessary. But you will have to stir a few times when using a microwave to even out the cooking.
  • No worries about scorching
  • No need to temper the eggs
  • No need to strain pudding if you started using a blender or food processor to mix everything.

Admittedly, microwave ovens aren’t efficient for large quantities. So it’s completely understandable why restaurants and bakeries might not use them. But for home cooks making one or two pies, it’s the best and easiest way.

One thing is for sure. It’s no longer tempting to use a mix (questionable taste and ingredients) or a grocery-store pie (where’s the love and homemade flavor in that?) when I can make a cream-pie filling in a microwave. It’s just too quick and effortless.

What is the difference between pudding and custard and cream-pie filling and pastry cream?

They all begin with milk and sugar. From there, it depends on how you choose to thicken the mixture. It also matters where you live as to how these terms are understood.

Some people describe pudding as having no eggs, as you see in the definition below.

Pudding is made by cooking the milk and sugar base and adding cornstarch to thicken the mixture. This leads to a semisolid consistency and creamy texture. It is usually served chilled, but it can be served warm or at room temperature.”

Others define custard as milk, sugar, and eggs with no other thickener.

Custard is made by cooking the milk and sugar base and adding whole eggs to thicken the mixture. When cooled, the mixture solidifies, leaving you with the jiggly consistency and silky texture.

We’re not talking about that kind of custard today. Never mind that some people use the term interchangeably with pudding or pie filling.

According to Leaf.TV,  Custard refers to any dish thickened with eggs. Often called Creme Patissiere, pastry cream is a rich and creamy custard filling in eclairs and cream puffs.

I would add cream pie filling to that last sentence.

The recipe I’m giving you uses cornstarch and eggs (yolks, specifically) to thicken the filling. I have another recipe for pudding/pie filling that calls for flour. The end result is a little more sturdy and not quite as delicate but still irresistibly tasty (and easy to make in a microwave.)

Ingredients and substitutions:

  • MILK: Whole milk will result in the richest and creamiest pudding. Using 2% and non-fat milk is acceptable and will also result in a thick consistency.
  • SUGAR: I use granulated sugar for the best taste. If you want fewer calories, try Swerve. It’s a 1-1 ratio when you substitute for sugar.
  • THICKENER: Cornstarch is my thickener of choice in this recipe. However, flour works, too. Cornstarch makes a lighter-tasting product with a more delicate texture. There is a time and place for either one.
  • EGGS: You only need the yolks for this recipe. Freeze the whites and save for meringue, angel food cake, or egg white omelets.

How do you freeze egg whites?

Here’s a nifty hack if you already own silicone tart molds or muffin cups.

How to make Microwave Pastry Cream:

pouring ingredients for microwave pastry cream into a blender.
Put all ingredients, except butter and extract, into the blender. Blend for 10 seconds.
transferring ingredients to microwave-safe pitcher.
Transfer uncooked mixture to a microwave-safe Pyrex glass bowl or 2-quart pitcher.
whisking pie filling during cooking in microwave.
Cook in the microwave on HIGH. Halfway through, whisk well. Repeat every minute after that.
showing thickness of pudding or pie filling.
The pastry cream should get thick like this.
adding butter and vanilla to cream filling.
Add butter and vanilla.
final whisking
Whisk well and cover with plastic wrap. If using for a pie filling, now is the time to put the cream filling into the baked pie shell.
wrapping bowl with plastic wrap pushed down on the surface of the pudding.
Push plastic wrap down to meet the surface of the pudding to prevent “skin” from forming when it cools.

I made a banana cream pie with this vanilla pastry cream by simply layering in a couple of bananas. See notes in the recipe for more details.

Microwave Pastry Cream for a Cream Pie Filling

Use a microwave to make this super quick, super easy cream pie filling from scratch.
Paula Rhodes
4.6 from 10 votes
Prep Time 10 mins
Cook Time 7 mins
Total Time 17 mins
Course Desserts
Servings 8 servings

Ingredients

  • 2 ¼ cups milk
  • 4 egg yolks
  • cup sugar
  • ¼ cup cornstarch
  • teaspoon salt
  • 1 teaspoon vanilla bean paste or vanilla extract
  • 2 tablespoons butter

Instructions
 

  • Dump milk, egg yolks, sugar, cornstarch and salt into blender or food processor. (See notes if you need to do this by hand.)
  • Blend for about 10 seconds. There may be a lot of foam. That’s OK–it will disappear when cooked.
  • Pour into a 2-quart glass batter bowl. (DO NOT USE A SMALLER CONTAINER–it could boil over and make a mess.)
  • Cook in a microwave on HIGH for 5-7 minutes. Whisk well after 3 minutes and every minute thereafter. Microwaves vary wildly. If the pudding mixture is not thick after 7 minutes, keep cooking and stirring until the custard looks like pudding. It should heavily coat a spoon.
  • Stir vanilla and butter into the thickened custard.
  • Press plastic wrap over the surface to prevent a skin from forming. Let cool on the counter (or in an ice bath if you are short on time) until lukewarm, then pour filling into prepared crust. Again press plastic wrap against the surface and refrigerate until filling is cold and firm.

Notes

Variation:
Banana Cream Pie:
Whisk cream filling and pour a thin layer into the pie shell. Slice and add a single layer of bananas, then cover with another layer of cream. Repeat. In the end, you should have three layers of cream with two layers of bananas, ending with the cream on top. Cover with plastic wrap pressed down to the surface of the filling.
No blender or food processor?
Use a whisk and some arm power instead of a blender. If you end up with any lumps, force the pudding through a strainer. It will be as smooth as silk

How would I make this into a coconut cream pie filling? and would i eliminate adding the butter at the end? thank you

Add a half-cup (or more) of coconut to the finished pastry cream. In addition, I like to sprinkle some toasted coconut on top of the pie.

I would not eliminate the butter. Butter contributes three things: 1. Flavor 2. Smoother Texture 3. Makes the filling set up firmer.

Love this recipe, and I discovered that you can made an amazing chocolate version by adding 1/2 c of cocoa to the blended mixture. So good! I'll never by boxed pudding again.

You're my kind of cook. Thumbs up!

This is THE BEST recipe for cream pie. I have made this several times and it turns out perfectly every time. I'm making it again this weekend as my niece requested it for her birthday party. I'll be using a graham cracker crust and putting it in individual cups - a little crust in the bottom, tamped down, then the filling and whipped cream on top. I'll actually be making it 3 times - one just plain vanilla, one with bananas and one with coconut. I love that I can use one recipe for all three versions. Hubby loves banana cream pie and until I found this recipe I rarely made it because no matter how low I cooked it, or how much I stirred it, it always stuck to the pan. Now it's super easy and super good!
