This custard-based German buttercream is made with just a few simple ingredients. Perfect for those who like a rich and silky frosting that isn’t too sweet!
I’m so excited to be sharing a new buttercream recipe with you guys today! Last week I told you all about How to Make Pastry Cream and today I’m going to tell you how to use that to make a delicious buttercream.
As you know, I am a die-hard Swiss Meringue Buttercream fan. It is THE best buttercream, as far as I’m concerned, but it’s not for everyone. It’s a bit high maintenance and some people find it either too buttery or too sweet, or both.
American Buttercream, on the other hand, is super easy to make, but gritty due to the powdered sugar and usually very sweet.
There are a variety of different buttercreams out there and I’m going to be experimenting with a bunch of them this year. I’m kicking it all off today with this German Buttercream!
What is German Buttercream?
German buttercream is a custard-based buttercream that consists simply of pastry cream, butter, and any additional flavourings you may want.
This buttercream is perfect for someone who likes a creamy, buttery frosting, but one that has a very subtle sweetness. How sweet you make it is up to you — the sweetness will come from the pastry cream itself.
I kept the sweetness fairly mild in mine but you can increase the sugar if you like. Alternatively, you can add additional powdered sugar at the very end.
How to Make German Buttercream
This buttercream is very easy to make, but it does require some pre-planning as you need to make the custard (pastry cream) in advance and let it cool. Here’s the step-by-step process of making German buttercream:
Step #1 – Prepare Pastry Cream
Make your custard in advance and chill to set. Refer to my How to Make Pastry Cream post for a detailed tutorial.
Step #2 – Bring your Butter and Pastry Cream to Room Temperature
The pastry cream will be thick and gelatinous and needs to be rewhipped before use. I just do this by hand with a whisk. It smooths out very quickly.
Step #3 – Beat your butter until Pale & Fluffy
Don’t skip this step. Whip it for a good 3 minutes on high. I use a paddle attachment because I like that mine scrapes the sides of the bowl, but you can use the whisk attachment if you prefer.
Step #4 – Add Pastry Cream a bit at a time
Slowly add the pastry cream about 1 Tbsp at a time while the buttercream is whipping. This is kind of like adding butter to a Swiss meringue buttercream. Incorporate it slowly.
I just used a regular soup spoon to add it in, it doesn’t have to be precise.
Step #5 – Beat until fluffy and smooth
Once all of the pastry cream is incorporated, beat the buttercream on high for 2-3 minutes until it is smooth and fluffy. Taste it to see if you want to add any more vanilla or powdered sugar for sweetness.
Storage and Perishability
You can store German buttercream like any other. It will last for a week or two in the fridge or can be frozen for up to 3 months. Bring to room temperature and rewhip before use.
I like to store mine in an airtight container in the fridge, but if I’m freezing it I spread the buttercream on a large sheet of plastic wrap, wrap it up, flatten it, and place it in a freezer bag.
Who is German Buttercream best for?
Like all buttercreams, custard buttercream is not for everyone. It is best suited for someone who likes a frosting that is:
- rich and silky
- not too sweet
This frosting is very buttery, which is why it’s important to whip that butter very well at the beginning and then again once you incorporate the custard.
You want to lighten it up as much as possible.
Since the buttercream is made mostly of butter (yellow) and pastry cream (yellow-ish), it will be more on the yellow side. Again, whipping that butter will really help lighten it up!
Take a look through my How to Make White Buttercream for tips and tricks on how to neutralize that yellow color.
Flavouring German Buttercream
You have a few options here when it comes to flavouring the buttercream. You can infuse the milk — I talk about this a bit in my Pastry Cream post, but the flavour will be diluted a bit once you add it to the butter. Or you can just add in flavouring at the end like any buttercream.
Here are some flavouring options to add in at the end:
- 8oz cooled, melted chocolate
- 2 Tbsp Instant espresso powder (of instant coffee) dissolved in 1 tsp hot water
- 1/2 cup caramel or dulce de leche
- Beat the butter with 1 Tbsp lemon zest and then add more lemon juice at the end if desired
- 1/4 cup freeze-dried berry powder
- 1/4 cup peanut butter powder
I can’t wait to hear what you guys think of this German Buttercream recipe.
I love that it’s silky smooth, not too sweet, and that I can add more sugar at the end if I want it sweeter. It’s much easier than Swiss meringue buttercream, but does require a bit of prep and planning.
If you find most frostings too sweet, but want something more stable than whipped cream, this is the frosting for you! Let me know if you try it!

Hi Indhuja! I would suggest trying this recipe instead: https://livforcake.com/ermine-frosting/
Tess says
Hello thank you so much for sharing i cant wait to try…can we color it and does it work over fondant….
Olivia says
Hi Tess! You can color it for sure. The buttercream is softer than something like an American one or a merignue one, so I’m not sure it would work as well under fondant.
Laura says
Can’t wait to try! But was just wondering, if I iced some cupcakes with this, are they safe stored at room temperature for a few hours or so they need to be refrigerated? Many thanks, Laura
Olivia says
Hi Laura! They should be fine for a couple hours but otherwise I would refrigerate. How long exactly do you plan to have them out?
Maral says
Hi, can a shop bought custard be used in this recipe?
Olivia says
Hi Maral! I haven’t tried it myself so I can’t say for sure.
Amalia says
I am not a big fan of ABC so I would like to give the GBC a try. Can it be used for icing and decorating a cake?
Thanks!
Olivia says
Hi Amalia! Yes for sure. It’s a bit softer than an ABC or SMBC but it should be fine to frost a cake.
Mona says
Hi. I want to make a peanut butter flavored German buttercream but I don’t have powdered peanut butter. Can I use the regular creamy peanut butter instead of the butter? Kindly help. Thanks.
Olivia says
Hi Mona! You can try it for sure but the buttercream is already on the softer side and adding the peanut butter will make it softer.
