A well-made bulletproof coffee closely resembles a creamy latte and to get that wonderful texture a milk frother is the best device to use. And a handheld frother is by far the best type. Some manufacturers claim their automatic electric frothers will do the job but a handheld model is the most effective and the best value.

Why use a milk frother for bulletproof coffee?

You can of course make your bulletproof coffee without using a milk frother. Many bulletproof coffee drinkers use a blender to make their drinks. But, to be honest, this is a bit like using a sledgehammer to crack a nut.

If you’re making a big batch of bulletproof coffee a blender would seem to be a logical choice. But even if you and your partner both drink the coffee do you really need a blender full every day? Probably not.

Added to that using a blender is such a faff and cleaning the thing afterwards is a nightmare. Which is why we recommend a milk frother.

With a milk frother you can make one or two cups of bulletproof coffee quickly and easily. No fuss, no mess and no need to take the device apart and spend ages cleaning it.

But – not all milk frothers are suitable for bulletproof coffee. Some manufacturers do claim their electric frothers are suitable for this type of drink but we wouldn’t recommend these devices. Again, like a blender it’s a bit overkill.

We recommend you use a handheld milk frother. These are small battery-operated devices which are very easy to use. They are great value for money and are just the tool you need to quickly make one or two cups of coffee at a time.

Best of all they create a really thick and creamy foam. Perfect for that early morning get up and get at ‘em cup of bulletproof coffee.

There are plenty of good handheld milk frothers out there but we’ve picked our top six for you.

1 – Bosenkitchen electric milk frother

Top of the list is this cracking little frother from Bosenkitchen. But, let’s clear up a little bit of confusion first. Bosenkitchen describe this device as an ‘electric milk frother.’ Er…. it isn’t. It’s battery operated.

However, that slight misstep in translation aside this is definitely the best milk frother for bulletproof coffee. Despite weighing in at only 100 grams it’s very powerful. The whisk rotates at a really high speed – it’s only around 2cm in diameter but the speed it goes creates a thick foam in no time at all.

Features of the Bosenkitchen milk frother

  • Light, handheld frother.
  • Uses 2 x AA batteries.
  • Ergonomic design.
  • Stainless steel shaft and whisk.
  • One touch on / off button.
  • Easy to clean.

How to use it

First of all, let’s talk about how not to use it. Don’t try to froth your coffee in a shallow contain or cup. Once you start frothing the liquid will go everywhere. Remember this is a powerful little device.

But using it is easy enough. Insert the frother into your bulletproof coffee before switching it on. Press down and hold the on button and as the liquid starts to foam raise and tilt the frother so it’s always in the foam. When you’ve got the thickness you want – this should only take 30 seconds or so – press the button to turn off the device before lifting it out of the coffee. And that’s it. Jobs a good ‘un.

To clean the Bosenkitchen milk frother simply hold it under running water or rinse the head of the whisk in hot soapy water.

This little milk frother does a great job and only costs around a tenner.

2 – Zulay Milk Boss

Probably the best-selling milk frother on Amazon. It has well over 80,000 reviews and can be used to whisk or foam just about anything. It’s really light, available in around 20 different colours and comes complete with a sturdy stand for the kitchen.

We can’t recommend this frother highly enough. It’s made from very high-quality materials and should last for years. In fact, Zulay provides a ‘lifetime happiness promise.’ Which is a cute way of saying a 100% lifetime guarantee. You can’t argue with that. As we said, this great little device will last for years. You will of course have to change the batteries every now and again…

The frother is very powerful and will produce a nice creamy foam in around 30 seconds. It has an on / off button on the top of the handle and is very easy to use.

Features of the Zulay Milk Boss

  • Light, only 91 grams.
  • Takes 2 x AA batteries.
  • Quality construction.
  • Available in many different colours.
  • Includes stand.
  • Lifetime guarantee.
  • Stainless steel shaft and whisk.
  • One touch on / off button.
  • Easy to clean.

How to use it

Just hold it like a pen, pop it into the coffee and click the on button. It’s pretty easy and you’ll soon master the technique. One tip is to swirl the whisk around and hold it at an angle once the froth begins to form.

After use, cleaning the device is simply a matter of holding it under running water. For a good clean keep the whisk running while you rinse it.

The Milk Boss is a great device which you’ll find dozens of uses for in the home. Not just for frothing your bulletproof coffee.

3 – HSIULMY USB milk frother

This frother uses a built-in 1200mAh battery which is charged by USB. You can use your phone, power bank or any other USB charging device to keep the power topped up.

The HSIULMY is a solid device and weighs twice as much as the other frothers we’ve reviewed so far. But it’s still easy to handle and comes with two different whisks. It also has three speeds so is extremely versatile. On its highest setting this is a very powerful frother and will have no problems at all in making you a foamy bulletproof coffee.

Features of the HSIULMY USB milk frother

  • 1200mAh battery.
  • Rechargeable.
  • 3 speed settings.
  • 1 x spring head (use this to froth your coffee).
  • 1 x whisk head.
  • Includes USB charging cable.
  • Made from ABS plastic with stainless steel stem and whisks.
  • Easy to clean.

How to use the milk frother

Like most handheld milk frothers this is a very easy to use device. The important thing is to remember to put the whisk into the coffee before you turn it on. Once in the liquid press and hold the on switch. Once it starts to foam move the whisk head slightly to keep it in the foam. Once the foam is frothy as you need, release the button and remove the frother from the liquid.

And that’s it. You’ll have a wonderfully creamy and frothy cup of bulletproof coffee. To clean the device just hold the whisk under a running tap for a few seconds.

Before use do make sure the device is always fully charged. The less power the less froth. So, don’t forget to plug in that USB every now and again. The great thing about this is that you can plug the frother into the USB port of your laptop to charge up while you’re enjoying the bulletproof coffee it’s just helped you make.

4 – CHINYA Milk Frother

This is a lightweight easy to use little device that will produce great cups of foamy bulletproof coffee every time.

It has a powerful battery powered motor and it will generate a lovely creamy foam within 30 seconds.

The CHINYA milk frother is very well made with a stainless steel shaft and whisk. Some users have reported issues after a few months but the frother does come with a lifetime guarantee.

It’s a nicely styled device and while it is a little more expensive than some of the other frothers we’ve reviewed it definitely does the job. It can be used on all kinds of milk and is powerful enough to mix a nice cup of foamy bulletproof coffee.

Features of the CHINYA Milk Frother

  • One touch switch.
  • High torque motor.
  • Takes 2 x AA batteries.
  • Lifetime guarantee.
  • Durable stainless steel whisk.
  • Creamy foam within 15 – 30 seconds.
  • Easy to clean.

How to use the frother

It’s a standard handheld milk frother so it works just like any other. But do be aware of the powerful motor so don’t switch the device on before putting it in the coffee or you’ll redecorate the kitchen walls.

When you’re frothing move the device slowly up and down to generate the creamiest foam. After only 15 – 30 seconds your foamy bulletproof coffee will be ready to drink.

It’s number four on our list but will is an excellent device for frothing and any other whisking jobs in the kitchen.

Check the latest pricing for the CHINYA milk frother.

5 – Wanderlife milk Frother

This is a fantastic frother and it comes bundled with lots of nice extras. It hasn’t been on the market that long and it differs from many other handheld frothers in that it is fully adjustable. It has three different speeds so it can handle any whisking job.

It also comes with three interchangeable whisks. You should use the double headed spring whisk on the highest speed to make your bulletproof coffee. It develops 13500rpm on the highest setting so it generates plenty of power to whisk that coffee.

Features of the Wanderlife Milk Frother

  • Powerful motor.
  • Produces foam in around 20 seconds.
  • Built-in 1200mAh rechargeable 18650 lithium battery.
  • USB charger.
  • Quiet operation.
  • 3 different speeds.
  • Includes 3 whisk heads.
  • Includes 16 latte art stencils (for when you feel creative).

Using the frother

The device holds its charge really well. When you do need to recharge it you can use any compatible charger including your phone, laptop or power bank. The different whisks provided with the device means it can be used for all sorts of tasks in the kitchen.

Despite the powerful motor it’s surprisingly quiet. To use it just click the on / off button and choose the speed by pressing the appropriate button on the body of the device. If necessary you can change the whisk in seconds. To clean the whisk just detach it from the body and hold under running water for a few seconds.

This really is a nice frother and definitely the one for you if you want a device that can do many different jobs in addition to frothing your bulletproof coffee.

6 – Dallfoll Coffee Frother

This may be the last milk frother we review on this page but it’s certainly not the least impressive. It’s another USB charged frother and probably the most powerful of all the devices we’ve looked at on this page. It really is a pocket dynamo. It reaches up to 13,000rpm on its highest setting and believe me it will absolutely blitz your bulletproof coffee. You’ll have a lovely foamy brew within 20 seconds.

Features of the Dallfoll Coffee Frother

  • 3 speeds up to 13,000rpm.
  • Charging indicator light.
  • On / off switch.
  • Low noise motor.
  • Built-in 1200mAh rechargeable 18650 lithium battery.
  • Fantastic foam in just 20 seconds.
  • 2 whisks provided – balloon and double head spring (use this one to froth your coffee)
  • Easy release system to change whisks.

Using the Dallfoll frother

The first thing you’ll notice about this device is how quiet it is when you switch it on. It’s not silent by any means but definitely quieter than most other handheld milk frothers. The frother comes with two whisks which are easily interchangeable. You need to use the double headed spring whisk for your bulletproof coffee.

When the coffee is prepared insert the whisk into the liquid before turning it on. Move the whisk head in a circular motion and as the foam forms move pull the whisk up slightly so it’s always in the top layer of the foam. It should only take 20-30 seconds to create a thick creamy foam.

When you clean the frother make sure you remove the whisks and hold under a running tap. Remember the body isn’t waterproof so keep it away from the running water.

A powerful but light device, this frother is ideal for bulletproof coffee. And, with two whisks, it will be a versatile tool for any kitchen.

What to look for when buying a milk frother for bulletproof coffee

As we mentioned way back at the top of the page the best frothers for butter or bulletproof coffee are the handheld models. They are far more suited to the task than the all-in-one or electric frothers.

We’ve reviewed six handheld milk frothers here but there are dozens available. They range in price from around £10 up to £20. But you can get them even cheaper than that. Some are available for 1p if you pay the postage from China. Don’t be tempted. You really do get what you pay for.

The best handheld frothers are cheap enough anyway. Yet most will last for a year or two, many much longer, but do be prepared for a shorter life cycle.

The main decision you need to make is whether you’ll go for a battery or USB model. Battery powered models are far more common but USB frothers have begun to appear. The battery ones are more convenient – until the battery runs out. But the USB frothers are more environmentally friendly and have lower running costs. A single charge will last quite a while and it’s really no hardship to charge the device every now and again.

Consider whether you want the frother purely for your bulletproof coffee or to do other jobs in the kitchen. If the later you’ll want to choose a device with more than one whisk. It should also have variable speeds to make it more versatile.

A frother with more than one whisk and variable speeds can do everything from frothing milk to beating eggs.

Finally, look at the weight of the frother. Some come in at less than 100 grams while others are over 200 grams. This is worth thinking about if you have difficulty holding objects.

How to make bulletproof coffee or butter coffee with a handheld milk frother

You’ll be delighted to know that making your bulletproof coffee with a milk frother is so easy. Most websites recommend using a blender but, as we said earlier, there’s no need to do that. It’s too much of a faff and you’ll spend more time cleaning the blender than making your coffee. No, a handheld frother is definitely the way forward.

What you need

A cup of high-quality brewed coffee
Tbsp butter (unsalted Irish Kerrygold is popular)
Tbsp coconut oil

What you do

Pour coffee into a cup
Add butter and coconut oil
Blend for 30 seconds with your handheld milk frother

That’s it. But of course, many people have their own little wrinkles on the process. Like this guy:

Not sure if bulletproof coffee is for you?

It’s not for everyone. To be honest when most people first hear of butter coffee their jaw drops and lips curl in distaste. But bulletproof coffee drinkers swear by it. It’s very high in calories and has added fat. They claim it fills you up, makes you ultra-alert and focused. It starts your day with a bang and propels you through it like a rocket. It’s a popular drink with followers of keto plans and low carb diets.

If you haven’t tried bulletproof coffee before do some research and give it a go if you feel it fits in with your lifestyle. If you’re already a fan get yourself a handheld milk frother to make your coffee taste even better in a far shorter space of time.
