If you grew up eating bakery-style cream buns, sponge cakes or doughnuts with that sweet, fluffy filling that somehow wasn’t quite fresh cream… hello, mock cream.
This old-fashioned mock cream recipe is ridiculously simple, uses basic fridge-and-pantry ingredients, and takes about 15 minutes to whip together. No fancy cake-decorating diploma required.
It’s sweet, light and fluffy, easy to flavour or colour, and handy when you want something a little sturdier than freshly whipped cream for cakes, cupcakes, doughnuts or lamingtons.
And because it’s made from ingredients you probably already have, it’s also excellent for those “I volunteered to bring a cake and completely forgot” situations. We’ve all been there.
What Is Mock Cream?
Mock cream is an old-school alternative to whipped cream made by beating butter and sugar until light and fluffy, then gradually adding milk and hot water.
It has a smooth, creamy texture but is sweeter and richer than fresh whipped cream.
You can use it to:
- fill sponge cakes
- sandwich lamingtons
- pipe or spread onto cupcakes
- fill cream buns and doughnuts
- decorate simple birthday cakes
- rescue a cake that looked much more impressive in your head than it does on the bench
Basically, if something needs a fluffy vanilla filling, mock cream is ready for duty.
Why You’ll Love This Mock Cream Recipe
There’s nothing complicated going on here.
You only need five ingredients, no cooking is required, and you can easily customise the flavour and colour depending on what you’re making.
It’s also useful when you’re preparing a cake ahead of time because it holds its shape better than freshly whipped cream. Just remember that this version still contains milk and butter, so it needs to be kept refrigerated.
Tips for Making Really Good Mock Cream
Start with softened butter
You want butter that’s soft enough to beat easily but not half-melted on the kitchen bench.
If the butter is too cold, you’ll struggle to get that lovely fluffy texture. If it’s practically liquid, the cream can become too soft.
Add the liquid slowly
This is probably the most important step.
Adding the milk and boiling water little by little gives the butter mixture time to absorb everything without separating.
If it looks slightly questionable halfway through, don’t panic. Keep beating.
Use caster sugar, not regular sugar
Caster sugar has finer crystals, so it dissolves more easily and gives you a smoother finished mock cream.
Nobody wants crunchy cake filling unless the crunch is supposed to be there.
Chill it if it’s too soft
If the mock cream becomes a little soft after beating—especially on a warm Aussie day—pop it into the fridge for 10–20 minutes before spreading or piping.
Easy Mock Cream Flavour Ideas
Once you’ve mastered the vanilla version, you can play around with it.
For chocolate mock cream, add a little sifted cocoa powder.
For lemon mock cream, add finely grated lemon zest and a tiny amount of lemon juice.
For strawberry or raspberry mock cream, use a small amount of berry flavouring or freeze-dried berry powder.
For coffee mock cream, dissolve a little instant coffee in the boiling water before adding it.
And obviously, you can add food colouring for birthday cakes, cupcakes or any occasion where somebody has specifically requested icing in a colour that does not occur anywhere in nature.

Mock cream is especially good as a filling for traditional-style cakes and bakery treats.

How Long Does Mock Cream Last?
Keep mock cream in an airtight container in the refrigerator and use it within three days.
If you’ve already filled or iced a cake with it, keep the finished cake refrigerated as well.
Bring it out shortly before serving so the butter has time to soften slightly and the filling isn’t rock-hard.
Can You Freeze Mock Cream?
We don’t recommend freezing this mock cream.
Freezing and thawing can change the texture and cause the mixture to separate, so it’s better to make a fresh batch when you need it.
Luckily, it only takes about 15 minutes.
Mock Cream Recipe FAQs
Is mock cream the same as whipped cream?
No. Whipped cream is made by whipping cream until it becomes light and airy. Mock cream is a sweet butter-based mixture made with butter, sugar, milk and water.
The flavour and texture are different, but mock cream works beautifully as a filling or icing.
Can I pipe mock cream?
Yes. If your mock cream is firm enough, you can spoon it into a piping bag and use it for cupcakes, cakes or doughnuts.
If it’s too soft, refrigerate it briefly before piping.
Can I colour mock cream?
Absolutely.
Gel or liquid food colouring will work, but start with a tiny amount. You can always add more. Removing neon-pink food colouring from icing is considerably more difficult.
Why has my mock cream split?
Usually because the liquid was added too quickly or the butter became too warm.
Keep beating and it may come back together. If the mixture feels very soft, refrigerate it for a short time and beat it again.
An Easy Old-Fashioned Recipe Worth Keeping
Mock cream isn’t fancy, and that’s exactly why we love it.
It’s cheap, quick, nostalgic and made from ingredients most of us already have. Whether you’re filling a sponge, rescuing tomorrow’s birthday cake or stuffing doughnuts because apparently we’re making excellent life choices today, this is one of those little recipes worth keeping tucked away.
