Homemade Magic Bullet: Using a Mason Jar with Your Blender

Want the convenience of making your protein shake right in the glass but don't want to drop the funds on a store-bought solution? Try a mason jar.

I've always wanted a Magic Bullet blender, but I never wanted to pay for it. After reading several mixed reviews I never dropped the $50+ to pick one up.

If you've never seen one of the infomercials, it's essentially a blender system that comes with a bunch of different sized cups that you can make your shakes, salsa, or what have you, right in the cup. Instead of using a regular blender and dirtying both the blender carafe and the cup or bowl you're going to eat out of, you make it right in your glass.

Certainly a first world problem if I've ever heard one, but if you're making yourself a lot of protein shakes (check out my recommendation here) or making other supplements, you go through a lot of glasses and a lot of clean up.

So when I came across this little tip on Reddit a few weeks ago I was excited to go home and see if it would work with my blender. As it turns out, your everyday mason jar is the same size as most blender attachments.

For $.79 each I picked up a bunch of mason jars and now have an easy solution for thwarting double clean-up duty.

If you want to see if your blender will accommodate a mason jar before you go buy a bunch of 'em, the opening of a normal jar is about 2 5/8″.

This is also a great way to make properly measured, individual frozen drinks for guests like frozen margaritas or daiquiris.  Or, do make-it-yourself milkshakes as a cheap date dessert and you can both customize your shake just the way you want.

The cap with the blades for the blender fits right on a typical mason jar. Note your blender may vary, they're not all the same size.

    Genius. Mason jars are great for their original purpose as well (e.g., canning and preserving).

    What blender do you use?

      Hey Mike, It’s an old Sunbeam I’ve had for years. I think I got it at Kmart.

    Or just use a stick blender – far easier!

    • Reply July 21, 2011


      Ed, I love stick blenders too they work great on protein shakes! Can’t use them for making frozen drinks, though, they won’t chop the ice.

    Similar solution to French Press coffee: http://www.bodum.com/us/en-us/shop/detail/K11102-01US/

    Instead of dirtying a press and mug separately, Bodum has combined the two–making the morning coffee brew much easier, and portable!

    Andrew R., I actually have one of those! Works pretty slick. I do find I get grounds sometimes.

    If you are making protein shakes, most places like GNC sell those shaker bottles that work pretty well. No clumps, and just throw it in the dishwasher when done.

    This worked perfectly this morning for a smoothie – love it!

    I will definitely have to see if this works with my blender when I get home from vacation. The thing I loved about the magic bullet when I had one, was that I never made too much shake for just myself. Portion control – it’s a beautiful thing.
    Some name brand foods come in regular mason jars, like Classico pasta sauce. I always keep them.

    Hey, kilelr job on that one you guys!

    Most Oster and some Hamilton Beach blenders fit the mason jars. Your best best is either of these brands with the blade assembly looking like the picture, simple and not elaborate. Some models by these manufacturers have more elaborate screw on assemblies that are larger and attempt to stabilize the large blender pitcher over a wider area and these models may not work as well.

    You can also “grind” small amounts of grain using a pint mason jar. Wheat berries, barley and popcorn do not work as the seeds are as hard as pea stones. However, triticale, rye berries, chickpeas, peas and lentils can be spun easily into a nearly fine flour and added to breads or pancakes. Kamut is somewhere in between, the final product is on par with very coarse cornmeal.

    All you need is some 7-10 speed Oster blender costing $20-25.

    That is an excellent blender hack. This setup will probably actually perform better than the magic bullet because the magic bullet has a really weak motor, around 300 Watts. Even the cheapest blenders you can find in the store will have a more powerful motor, 450 Watts or higher. Blend away! And thanks for testing this out.

    Now you need to get the “Cuppow” to drink out of your jar. Love these things. http://cuppow.com/

    Also, many commercial products come in jars with this size opening so you can recycle. For instance, Classico Pasta Sauces actually come in Mason Jars (just make sure to wash thoroughly first, and remove the labels as well). Down here in Texas, Mrs. Renfro’s salsas and relishes, etc. have the same size mouths to their jars. I be willing to bet that there are a multitude of others.

    great idea – I have the magic bullet and love it, however, I did not want to use the plastic cups–i am trying to avoid using plastic in connection with food as much as possible. I am going to take the blender piece from the bullet to the store to see which mason jar it fits on. thanks for sharing

    this is a great idea all be it an old one to me…I have been doing this for about 6 – 8 months now.
    It is so much better & easier than using the original blender jar…
    Mason jars are just about the coolest thing invented! They have so many uses besides canning….

    Do you need an air pocket?

    I have the feeling this may make a great spice mill attachment. I can’t wait to try. Heck I would buy a blender the right size to do this. It’s so hard to find a spice mill that’s got the power, the blade durability and will do it in removable, washable, glass or stainless steel.
