Made without icing sugar / powdered sugar, this is actually an old fashioned frosting called “Ermine Frosting”. If you’ve never heard of it before, the ingredients and method will intrigue you!

My secret Fluffy Vanilla Frosting

I call this my “secret” Vanilla Frosting because it’s not a widely known type of frosting and people are always flabbergasted when I tell them how it’s made using butter, milk, flour and sugar. Sweetness and richness: Much less sweet than buttercream with 60% less sugar. In reality it is quite rich because it uses 225g/2 sticks of butter but it doesn’t taste rich because of the very fluffy, whipped cream-like texture. Uses: Piped or spread onto cakes and cupcakes, or used in place of cream to dollop onto or on the side. How it sets: At room temperature, it’s soft and fluffy but firm enough to be piped into tall swirls. In the fridge, it will set and become firmer, but not hard like butter. This frosting does not get a crust. Storage: Keep covered in airtight container or cake dome. On counter on mild days up to about 22°C/71°F. Refrigerate on warmer days that makes butter melt. Best served at: room temperature. If too cold, the frosting is firmer than ideal. It’s my best all-rounder that’s a hit with everyone. Take a classic buttercream, in all its rich, sweet glory, and a lightly sweetened vanilla whipped cream, and this Vanilla Frosting sits squarely in the middle. But unlike buttercream, it’s 100% silky smooth. And unlike whipped cream which deflates within hours, this Vanilla Frosting will hold a tall piped swirl for days and days. This looks and pipes like buttercream, but it’s WAY less sweet and rich! This frosting is actually an old fashioned frosting called Ermine Frosting. Also known as boiled-milk frosting, roux frosting and mock cream, none of these names sound particularly flash nor do they capture the magic of this frosting that has a cult following. Some declare it as the best frosting in the world!

About this Fluffy Vanilla Frosting

Though the proper name of this frosting is Ermine Frosting, I’m going to continue to call it Fluffy Vanilla Frosting because that’s exactly what it is – and it sounds a lot more flattering than the real name!😂 The method by which it is made will sound highly unusual: hot milk, flour and sugar is cooked on the stove until thickened into a thick custard texture, then once cool it becomes a thoroughly unappetising looking bowl of gluey-jelly which is then whipped into butter.

And this is when the ugly duckling transforms into a beautiful swan. Because suddenly, you’re staring into a bowl of what looks like whipped cream. Except….. you haven’t used cream at all. You touch it and know that it’s firm enough to pipe into sky-high swirls. You taste it, and it’s silky smooth. A cross between buttercream and whipped cream!

What you need for this Fluffy Vanilla Frosting

All you need is butter, flour, milk, sugar and vanilla. Flour?? I hear you query. YES. That is what thickens this into a frosting texture. I promise you will not detect even the faintest bit of flour once finished – not in texture and certainly not taste.

How to make my secret Less-Sweet Fluffy Vanilla Frosting

First, we make the roux. It’s just like how we start creamy-sauce savoury foods like Mac and Cheese – except it’s sweet, and we take it much further until it’s very thick.

Cooling the roux / making ahead – I usually cool on counter for 20 minutes then refrigerate for 30 minutes or so to speed things up but don’t let it get fridge cold because otherwise it won’t mix together well with the room temp butter (because the temperatures are too different). You can also leave it overnight in the fridge but take it out about 1 hour prior to dechill it and bring to room temperature. Now, we whip it up like any other frosting.

  1. Beat butter until creamy – just for a couple of minutes. We don’t need it to become aerated because we will be whipping the combined mixture like you do whipped cream and at this stage it will fluff up more;
  2. Add dollops of the roux, beating as you go. Take about 1 minute to add all the roux in, this will ensure your Frosting stays smooth;
  3. Beat, beat, beat – Add vanilla and a pinch of salt for flavour, then beat for another 2 to 3 minutes, just like you’re whipping up a big bowl of cream; and
  4. Voila! Your Fluffy Vanilla Frosting is done!

How to use this Fluffy Vanilla Frosting

Spreading and piping

Spread it onto cakes (like Vanilla Cake) and cupcakes  Vanilla Cupcakes or Chocolate Cupcakes). Or transfer to a piping bag and pipe sky-high swirls, as pictured throughout this post (Wilton 2D tip). In fact, this frosting was the traditional frosting used for Red Velvet Cake! It was only in modern times that cream cheese frosting became the frosting of choice for Red Velvet. You can pipe sky-high mounds of this frosting onto cupcakes, and you won’t find it sickly sweet like with buttercream!

Flavours and colouring

Treat it like your everyday buttercream – this frosting can be tinted and flavoured with concentrated flavouring. To make it Chocolate flavoured, just whip in 1/4 cup cocoa powder at end. Melted chocolate doesn’t work as well because it weighs it down. Note: I haven’t tried using fresh citrus like lemon, lime and orange to ensure it doesn’t split.

Storage

The butter in this frosting will require refrigeration if the temperature is warm enough for the butter to start softening – this causes the frosting to droop. I find that up to about 23°/73°F, this frosting is fine out on the counter. If you are forced to refrigerate, make sure you take cakes out 1 1/2 hours prior to serving and cupcakes out 1 hour prior so they come to room temperature. The frosting firms up in the fridge (because the butter goes hard) which is not very pleasant to eat! You need the frosting to come to room temperature so it’s creamy and soft again. It will soften faster than fridge-cold butter because the fridge-cold frosting is not as hard as butter. So, now you know my secret frosting recipe. 🙂 I’ve been making it for years, relishing in how people who ordinarily shy-away from sky high mounds of frosting have dived into it after I assured them that it’s way less sweet and rich than typical frostings. Tell me what you think if you try it! – Nagi x
