There is no better way to satisfy a sweet tooth craving than to bite into a donut or cupcake with a deliciously sweet, oozing filling.
But unfortunately, the filling can’t always be baked straight into the product. Luckily, we have these extremely useful tools called filling injectors or fillers.
Like with any product, some are way better than others, and choosing the perfect one for your needs can be a nightmare!
So, what are the best filling injectors? The best one is one that will work for your specific need. First, choose what you want to do with it before anything else. Then look at the design of the product and whether it is easy to use and durable.
In today’s article, we will be looking at exactly what an injector is and what makes a good one. Then we will discuss our favorite cupcake fillers and donut injectors available online.
What Are Filling Injectors?
Filling injectors might sound like something used in an engineering conversation or even a medical facility, but it is literally what it sounds like: a piece of equipment that injects, in our case a filling, into something else.
There are many items such as cupcakes, donuts, and éclairs that need a delicious flavor-packed filling on the inside. These fillings can include anything like pastry cream, creamy custard, fruity jams, chocolate ganache, and caramels.
Injectors are fairly easy to use. Whichever filling you want to insert into your pastry, simply place it into the injector, push the tip into the pastry, and squeeze.
What also makes injectors so great is that you can also use them to moisten cakes. Instead of having to struggle brushing on syrups, you can now place it into your injector and inside it into various areas in the cake or cupcake.
Even though there are hundreds of filling injectors on the market, they all pretty much do the same thing and also almost have the same features. What makes some unique from the others is mostly in design.
This includes how it was designed, its size, the materials it is made of, and how easy it is to use. This is mostly what will affect your choice.
Buyer’s Guide For Filling Injectors
Filling injectors may seem simple and very easy to use, and they definitely are. But trust us, when things go wrong they go horrifically wrong!
If the mechanisms of the injector don’t properly fit into each other, if the overall quality of the injector is bad, or if the design is flawed, you can end up with a sticky mess that will take forever to clean.
Another big factor to consider besides quality is function. What do you want to use the filling injector for? Do you want to fill donuts? Do you need to insert frosting into cupcakes? Or use it to moisten cakes and pastries?
If you can decide what you want your injector to do, you will have a much easier time choosing the correct design.
The injector consists of mainly two parts: the body and the tip. The body part is where the filling goes, so it is important that whatever the tube is made of, it won’t leak or change the flavor or color of the filling.
For example, some cream-based fillings will discolor when they come into contact with copper or other metals. They could also potentially get a metallic taste from these materials.
So when choosing an injector, take this into consideration. Personally, we feel like for something like this (that will probably be used for multiple types of fillings) it is best to choose one made from hard food-safe plastics.
Glass is also a fantastic option as it is completely non-reactive; however, it is a very fragile material to work with. Higher-end filling injectors used for commercially made pastries are usually made from stainless steel for durability.
Then for the tip or nozzle, there are usually a few options. They vary in shapes and sizes and can perform a wide variety of functions.
They can be made from metal or hard plastic. Anything soft and pliable won’t work as they will bend when you insert them into the pastries.
The durability of the filling injector depends on the material it is made of, both the body and the nozzle. The injector should also be easy to clean because any residual product can contribute to shortening the equipment’s shelf life.
For example, it can cause the item to rust (if made from metal) or deteriorate (if it is made from cheap plastics).
Filling injectors made from hard food-safe plastics, glass, or a durable metal like stainless steel will last the longest.
Nozzles made from metal will last longer than plastic nozzles but can be more expensive because they are considered to be of a higher quality.
If you are only planning on using your filling injector occasionally, rather choose a hard plastic nozzle. Choose metal nozzles if you are an advent baker and plan on using them often.
What Makes A Good Cupcake Filler?
Cupcakes are decorated beautifully and often intricately, so you need a filling injector that will carefully insert your filling without ruining all of your hard work.
The same applies to other pastries. You need something that will allow you to easily inject the filling without damaging the entire pastry.
We also always prefer kitchen equipment that can perform multiple functions. So injectors that can insert different types of fillings with different, interchangeable nozzles or tips, are in our opinion, your best value for money option.
This way you don’t have to buy a different injector for different functions and it will help you de-clutter your drawer!
What Makes A Good Donut Filler?
The filling cavity in a donut might be slightly bigger than a cupcake depending on the type of donut you are making.
Usually, donuts that have a filling on the inside is a solid donut and not a ring donut. This makes inserting the filling a lot easier since the cavity is bigger.
With a bigger cavity to fill we need to make sure we get the whole cavity filled, because who likes eating a donut full of air? Not us!
You need a longer nozzle that will be able to go deeper into the cavity and also one whose tip is wide enough to insert a lot of filling.

1. Cupcake And Donut Filling Injector 9-Piece Set
This nifty set is one of these items that serve multiple functions and don’t just add to the cluttering cupboard we all have!
It is an incredibly versatile injector that can perform virtually any function.
This injector comes with 9 different interchangeable nozzles which allow you to not only fill donuts but to decorate cupcakes and even cakes as well.
Included in the set is a nozzle with a longer tube specifically made for filling donuts. It will create a big enough hole so you can insert a ton of filling without leaving a massive crater!
And because these nozzles are interchangeable, you can easily switch between them instead of having to refit an injector with a new nozzle. Trust us, that is time-consuming, frustrating, and extremely messy!
The nozzles screw on tightly which prevents fillings from leaking out and creating a mess. And the injector itself is made from durable hard plastic that won’t affect the filling or pastry in any way.
A design feature we truly appreciate on this product is that it is see-through. This will help you see exactly the amount of filling you are inserting and when you need to refill the tube.
2. Ateco Bismark Metal Piping Tips
Even though this product only includes the piping tip, we still think that it is a fantastic option for anyone who already owns piping bags or at least knows how to use them.
It also makes a great addition to any piping nozzle collection, especially as a filling tool.
The nozzle has a thin and long design, perfectly suited for filling longer cavities such as donuts and eclairs.
It is made from stainless steel and measures roughly 0.25 x 1 x 0.25 inches. Stainless steel is an extremely durable material and will also not react with the fillings you use.
Even though this nozzle is far simpler than the other injectors that might perform more functions, it still performs its function far better than a ton of other options.
We recommend this product to anyone who is looking for a simple solution.
3. Topenca Supplies Frosting Decorating Syringe
This decorating syringe from Topenca Supplies is another multi-functional product.
It is made from aluminum so is a very budget-friendly non-reactive option to have.
And it is more durable compared to other materials.
Seeing it is actually a decorating product, it does include decorating nozzles. Trust us though, these can definitely still work as a filling nozzle. It also does have a donut filling nozzle (the thin ones).
The set also comes with a handy small spatula that will make inserting the filling much easier than using a spoon. The spatula can also be used to smooth out the filling at the exit of the cavity or for general use in the kitchen.
The only downside to this injector is that there is no way to see the filling inside, making it harder to control how much filling you are inserting and to know when to refill it.
4. Kuhn Rikon Stainless Pastry Bag

It also has 5 small nozzles and 1 filling nozzle.
They have also smartly included 2 different adaptors so you can easily swap out the nozzles.

The marks will also ensure that the same amount of filling is inserted into each product, taking amateur skills to a professional level!
