Why Homemade Buttercream Never Tastes Like Bakery Buttercream

June 12, 2026

You followed the recipe exactly. You softened the butter, sifted the icing sugar, and beat it all together. But when you tasted the result, something was off. Too sweet, slightly greasy, or just flat. Meanwhile, the buttercream at your favourite bakery is light, silky, and has that flavour you can never quite replicate at home. So what are they actually doing differently

Why American Buttercream Falls Short

The recipe passed around most widely online is American buttercream: butter and icing sugar, beaten together, sometimes with a splash of milk or cream. It works, and it pipes reasonably well, but it has a core problem. Icing sugar is intensely sweet, and when it makes up most of the recipe, there is no escaping that one-dimensional flavour. The more you add to stiffen the consistency, the sweeter and more cloying the result.

Some bakers try reducing the sugar, only to end up with something too soft to hold a swirl. Others add cream cheese or flavoured extracts to balance things out, but that changes the character of the buttercream entirely. The result is always a compromise.

Bakeries producing those perfectly smooth, subtly creamy celebration cakes are almost never using American buttercream for their decorating work. They use a different base.

What Professional Bakers Use Instead

The buttercream behind bakery-quality finishes is Swiss meringue buttercream. Instead of relying on icing sugar for structure, it builds around a cooked meringue base, with real butter folded in. The result is naturally less sweet, lighter in texture, and far less likely to leave a coating of fat on the tongue.

It also behaves differently when you work with it. It spreads smoothly, levels cleanly, and holds detail in piped designs in a way that icing sugar-based buttercream cannot match.

The problem is that making Swiss meringue buttercream from scratch is genuinely difficult. You need a sugar thermometer, careful temperature control, a stand mixer, and a fair amount of time. Even experienced bakers find it can split mid-process, leaving a curdled, greasy mess right when they need it most.

A Ready-Made Option That Does Not Cut Corners

This is exactly why Frostella Buttercream was created. It is a ready-made Swiss meringue buttercream, freshly made in small batches with real butter, sugar, egg whites, and vanilla. No additives, no preservatives, nothing artificial. It is the UK's first additive-free ready-made buttercream.

Orders are dispatched within one business day, with free next-day UK delivery via Royal Mail Tracked 24.

The Family Pack (500g, £14.99) frosts around 12 cupcakes or a 6-inch two-layer cake.
The Party Pack (1000g) covers a 10-inch tall cake or around 24 cupcakes.
The Big Bake Tub (1500g) is there for bigger bakes. Every review left so far has been five stars.

One thing to know before you open the pack: Swiss meringue buttercream contains real butter and egg whites, and these can separate during storage and transit. The buttercream may look curdled, lumpy, or broken when you first open it. This is completely normal and does not mean it has gone off. Stirring gently or leaving it at room temperature will not fix it.

Here is what to do:

Empty the entire pack into a microwave-safe bowl
Microwave for 5 seconds on medium power
Whip with a hand mixer on medium speed until smooth and creamy

That is all it takes. For an even smoother, bubble-free finish, use a stand mixer with the paddle attachment on low-medium speed for around 15 minutes. The buttercream comes together into exactly the light, silky consistency you would expect from a professional kitchen.

Why does my homemade buttercream taste too sweet?

The most likely cause is the type of buttercream. American buttercream relies heavily on icing sugar for its structure, and icing sugar is intensely sweet by nature. Swiss meringue buttercream uses far less sugar relative to total volume, which is what gives bakery-style buttercream that lighter, creamier flavour.

Is ready-made buttercream as good as homemade?

Yes, if it is made to the same standard. Frostella uses real butter, sugar, egg whites, and vanilla, with no fillers or artificial ingredients. The texture and flavour are equivalent to a well-made Swiss meringue buttercream made from scratch, but without the equipment, the timing, or the risk of it splitting on you.

How much buttercream do I need for a celebration cake?

The 500g Family Pack covers a 6-inch two-layer cake or around 12 cupcakes. For a 10-inch tall cake or around 24 cupcakes, the 1000g Party Pack is the right choice. The Big Bake Tub at 1500g handles 36 or more cupcakes.
