What is ermine buttercream?
Also known as flour buttercream, boiled milk frosting and heritage frosting - this buttercream is made with milk pudding base (milk, flour, sugar, salt) and unsalted butter. Since there is no eggs in this recipe, it's significantly easier and cheaper to make than meringue based recipes. Not to mention the better flavour you're getting.
It's similar to German Buttercream frosting which is the holy grail of frostings in Croatia, but much easier and again - doesn't require eggs to make custard, which then gives you a delicious, but yellow frosting.
On my quest to find the best buttercream frosting - more than three years ago - I'd discovered a blog called The Tough Cookie. I'll forever be grateful to Nila for introducing me to this wonderful frosting, which had some of my cake testers confused for whipped cream+mascarpone frosting. Yes, it's that light! 🙂
Since my first encounter with Nila's base recipe, I adapted it to suit my needs and preferences, but also made a lot of different flavours, such as chocolate, raspberry and pistachio. There are more to come in the cake cookbook I'm currently writing, so stay tuned! 🙂
Why you'll love this frosting
- It's egg free.
- It has the perfect balance of sweetness - no more sacrificing flavour to get the consistency right.

- It's easy to whip up, you don't have to pay attention to reaching certain temperatures.
- It colours and pipes beautifully.
Ingredients you'll need
- All-purpose flour

- Salt
- Butter
- *Vanilla (or other flavourings)
How to make ermine frosting (step-by-step)
Step one
In a small heavy bottom saucepan whisk together flour, sugar and salt. Add whole milk and whisk until everything is combined or until there are no lumps or flour floating around (like showed in the picture).
Step two
Cook the mixture on a medium-high heat, whisking constantly so it doesn't catch on the bottom. Some prefer using a silicone spatula, but I get better results with no lumps using a whisk.
The cooking is done when the mixture thickens quite a bit and bubbles appear on the surface, just like when making a pastry cream. From that moment on, cook for another 2-3 minutes to get rid of possible flour aftertaste and you're done.

Step three
Strain the pudding base through a fine mesh sieve to make sure there are no lumps and you get a smooth texture. If you want it to cool quicker, use a larger, shallow plate. Cover with cling film touching the surface to prevent skin forming and leave to cool at room temperature.
You can let it cool in the fridge if you're in a hurry, but please make sure it's room temperature before mixing it up with butter.
Step four
After your pudding base is cooled and ready, give it a stir with a silicone spatula or a spoon before incorporating with butter. This is how your pudding base should look like when it's ready.

Step five
In a bowl of a stand mixer (or using an electric hand mixer), beat the butter for at least five minutes, until it becomes really pale (almost white) and fluffy.
Step six
While the mixer is still running on a medium speed, add one tablespoon at the time of the pudding mixture, making sure it's nicely incorporated with the butter before proceeding to add another one.
Once you've added all of the pudding, beat on medium-high speed and scrape the bottom of the bowl once or twice to make sure everything is combined. Add in the vanilla and give it mix one last time.
That's it! You got yourself a delicious, fluffy, vanilla flour buttercream! 🙂
My top tips for success every time
- Beat the butter for full 5 minutes, even longer if you're making a double batch. I know it seems a lot and your hands might hurt if you're using an electric hand mixer - but it will make all the difference in getting that light and WHITE frosting.
Scrape the bowl with a silicone spatula every now and then to ensure every bit of butter is thoroughly beaten.
- Make the pudding base the night before the day you plan to complete the frosting and assemble the cake, so you don't end up panicking if it doesn't cool quick enough. Time management is everything. 😉
- If you need to make a lot of frosting, I'd rather make one or double batch at the time , just because it's easier for the mixer and you won't risk messing up the ratios.
When I'm making a three layer 6-inch cake and want to have enough buttercream to generously fill, frost and do various decorations (different colours etc.), I'll make a batch using 300 or 350g of butter. I'd rather have some leftover than not enough.
Just move the serving slider until you see that number and it automatically calculates the rest. 🙂

FAQ + Troubleshooting
Most likely one of your ingredients was too cold, either the pudding base or the butter. Not to worry, all you have to do is heat it up a little bit - I usually use a hair dryer outside of the bowl. Do it one bit at a time, so you don't melt the butter and keep whipping it until it comes together.
Two situations might have occurred.
1. It's just too hot, so your ingredients were softer/hotter than needed. Whack the bowl in the fridge for 20-30 minutes and check again.
2. You tampered with measurements and possibly added more milk/sugar, which leaves you with a softer pudding base and ultimately softer buttercream.
You sure can, but adding more sugar will make the pudding base looser (and a softer buttercream), so you need to add some more flour too, to keep the consistency right.
1. Are you sure you measured everything correctly?
2. You probably didn't cook it long enough. Although I always try to explain the process the best I can, the things you end up doing are beyond my comprehension . Maybe your hob runs colder than mine. Maybe you've used a different pan that needs more time to heat up.
Yes you can. I've made the vegan version successfully using soy and rice milk. I've also tried using oat milk, but it leaves too much of an aftertaste. I suggest you use the one you like the taste of or the one that has the least noticeable taste. Plant based milks are usually more watery than regular cow milk, so it's important to use more flour in order to get the same thickness of the pudding base, that is - roux.
This is also one of the most common questions I get asked by experienced home cake bakers. I don't use fondant, nor have I ever used it, so I can't speak from personal experience. That said, from what I've gathered, I don't see why not. Like every other buttercream, it firms up in the fridge because of the butter solidifying, so it can hold up fondant very well without collapsing.
You can, just make sure to bring it up to room temperature ( around 21˚C/70˚F) and then whip it up to bring back the fluffiness. However, if possible, make it fresh on the day of stacking the cake, because refrigerating might make it lose some of its volume.
That said, I've tested on multiple occasions leaving the buttercream in a bowl at room temperature overnight (tightly covered with plastic wrap) and didn't have any issues.

flour buttercream recipe
Description
Ingredients
Vanilla buttercream
- 35 g all-purpose flour
- 160 g white caster sugar
- ¼ teaspoon salt
- 280 g whole milk
- 250 g unsalted butter
- 2 teaspoons vanilla extract
Instructions
- In a small saucepan (I always use heavy-bottomed one to prevent burning) combine flour, sugar, salt and milk. Cook over medium-high heat, stirring constantly with a whisk until it thickens and bubbles appear on the surface. This can take about 15 minutes.
- Once it's done, strain it through a fine mesh sieve into a shallow plate to get rid of any lumps. Put a cling film over it touching the surface to prevent "skin" forming and let it cool to room temperature. This is your pudding base. You can do this in a fridge, but before using it let it come to room temperature.
- Using a stand mixer fitted with the paddle attachment, beat the butter for at least 5 minutes until it's pale and fluffy. Then add spoonful by spoonful of previously made pudding. Mix until it's all nicely incorporated and with no lumps. Add vanilla extract and mix until everything is combined.
Notes
- If you don't have a stand mixer, you can use a hand mixer.
- If you still don't own one, I advise you to buy a kitchen scale - they're cheap and easy to use, and always guarantee the same results in baking!

I am very familiar with this frosting as my mother always used it on her red velvet cake. She described it as tasting like whipped cream. This is my favorite cake! I have pictures, on my 5th birthday, blowing out the candles on my red velvet cake (I'm now 62). My mother made the pudding using a double boiler, and that is how I make it. My frosting is perfect every time. Thank you for introducing this delicious frost to bakers of today!
Dear Ann,
thank you so much for sharing your memories and story, it was a delight to hear them. I will surely try and make the pudding using a double boiler to see if it makes the frosting even better than it is now. Thank you for sharing this with me!
Hope you have a lovely day x
This is beautifully light and tastes a lot like whipped cream. How long can it safely sit at room temp? Thanks so much for this wonderful recipe!
Hi, Deb! I'm happy you like it and think so, it's my favorite frosting! 🙂
If you're asking for just completed buttercream, before the assembly, I've let it a whole day one day, because something went wrong in the kitchen, so I couldn't assemble the cake on time. If you're asking for the assembled cake, it can be at room temperature for 2 days, maybe 3 if it's not too hot and if the buttercream was freshly made when the cake was assembled.
However, if you want to be on the safe side, I suggest keeping the cake in the fridge, but letting it come to room temperature completely before serving. Ideally 2-3 hours for a fully assembled cake.
Does this help you? x
Hello ana 🙂 I am so so happy that i have tried your ermine frosting from your oreo cake recipe. I have always hated the sickeningly sweet american buttercream but also found that swiss meringue cream is a little lackluster (mostly taste like butter) 🙁 So I have always been on the hunt for the perfect balance, and chanced upon your ermine frosting on this website! Tried it once and it was a success! It was so easy to work with, especially with Singapore's hot weather :") I have always tried a multiple recipes from you and they work wonders! I just wanted to say keep doing what you are doing and keep those recipes coming, I love them!
Hi Ana,
Thank you for your detailed instructions and photographs- really helps for new bakers like me! I'm thinking of making a tangy lemony frosting; do you think it will work if I replace maybe 5 tablespoons of milk with lemon juice, and cook it over the stove with the dry ingredients?
Cheers! (:
Hi Jav,
so happy you enjoy the detailed explanation. 🙂
For lemon frosting, I would add freshly grated lemon zest at the very end, instead of vanilla extract. You can also add a couple of tablespoons of lemon curd. If you add the lemon juice to the milk mixture, the acidity from the lemon will curdle the milk and you will end up with split, curdled, cheesy mixture.
Usually, the oils released from the lemon zest (make sure to grate directly over the bowl) are enough to bring out the lemon flavor.
Hope this helps! x
