Protein Mug Cake Mix

Delicious Microwavable Cake With 33g of Protein.






$3.00 (NZD)

Protein Mug Cake Mix

NZ Protein's Mug Cake Mix is a delicious microwavable cake with a huge 33 grams of protein per serve. Think mud cake - but made in a mug, and with gains.

We've formulated our recipe to be ridiculously easy as it just needs water and microwaving for less than a minute!

It makes for a great high protein treat and satisfies sweet tooth cravings. Because it's low in sugars and fat you don't even have to feel bad about eating cake.

The protein used is hydrolysed collagen from beef. Collagen is the connective tissue that accounts for up to 30% of proteins in our body.

Collagen is the most important structural protein in our body and the primary protein in connective tissue such as bones, tendons, ligaments and cartilage.

Collagen makes up 90% of connective tissue, 90% organic bone mass, and 70% of our skin and has unique functional properties over other proteins such as whey and casein.

This product does have some carbohydrates from flour. We tried to remove the carbs but the product didn't work, so there are carbs but the sugars are low.

Delish! Perfect treat when craving something to 'hit that spot'
Review by: Tracee on Thu, Jul 11, 2024 4:10 PM
It's alright. Not my favourite protein dessert from these guys but it's nice for variety. I had more success cooking it in a bowl instead of a mug.
Review by: Nathan on Mon, May 13, 2024 4:05 PM
I found this not to be to my liking, I do think I will try in a more shallow dish though so this can cook a bit more even.

Such an easy snack. Amazing macros. Well-priced. Delicious

Not nice, deflated to nothing and was dry.

Love this great flavour easy to make. Good protein boost.
Review by: Shona on Fri, Sep 15, 2023 8:27 AM
Feels like such a treat, definitely curbs the sweet tooth cravings and boosts up protein intake
Review by: Kate on Sat, Sep 2, 2023 1:13 PM
Easy to make, hits that sweet tooth spot so well, like the consistency & taste, I've now ordered 5 more for those craving moments 😍
Thanks NZ Protein another win on another great product 👌
Review by: Alannah on Tue, May 30, 2023 9:33 PM
Pretty solid. Gotta ensure there's ample room in mug for it to rise but tastes good 👍
Review by: Aaron on Thu, Mar 30, 2023 1:13 PM
These are actually the best thing I’ve ever tasted. So gooey and rich. Tastes just like a chocolate lava cake 👌🏻. I posted a picture to my IG story and so many people have since ordered and thanked me for how good they are…don’t wait, try them for yourself!!!

I keep a couple of these in my locker at work for those lazy days when I haven’t made my lunch.
Review by: Elizabeth on Wed, Feb 1, 2023 1:15 PM
C’est mangeable mais vraiment pas terrible.
Review by: Calvin on Fri, Jan 6, 2023 6:32 PM
I followed the instructions, but it did not turn out well. The texture was very unpleasant. I will stick to the chocolate mousse (which is delicious).
Review by: Tania on Sun, Nov 27, 2022 3:06 PM
This is awesome if you miss your chocolate cake hit. Admittedly its a bit hit and miss in getting the full serving to cook properly without going back and heating it some more, but the taste for me is bang on. A little rich to eat in one go so i usually put it down for 30 minutes and finish it off later.

So quick and easy with great taste

Very nice, a perfect cake with heaps of collagen

These are delicious, so easy and quick to make.
Review by: Angie on Fri, Aug 5, 2022 6:31 PM
Doesn’t go cakey, just stays like uncooked, hot batter. I even tried cooking twice as long and no luck. Tastes ok but the texture is a disappointment.
Review by: Bree on Mon, Aug 1, 2022 1:07 PM
So good!! I wish they sold them in bulk bags cause I buy so many of them 😋
Review by: Anonymous on Wed, Jul 13, 2022 12:17 PM
This company has several really good products, this isn't one of them. Consistency is odd and it just tastes like mushy protein powder. NZPROTEIN REPLY: sorry it hasn't been good for you, we've sent you an email
Review by: Anonymous on Wed, Jul 6, 2022 12:29 PM
Not nice at all. Did not cook properly, even with cooking it for over twice the recommended time. Also just tasted of artificial sweetener. Really yuck.
Review by: Kiri on Mon, Jul 4, 2022 7:29 PM
Wow yummy this ones a winner
Review by: Sarah on Thu, Apr 28, 2022 7:33 PM
My fave this one
Review by: Jo on Mon, Apr 25, 2022 12:15 PM
These are delicious, I've been craving a decent mug cake for a while. So impressed with these. New fav dessert!
Review by: Tania on Wed, Apr 13, 2022 9:02 PM
These are so yummy, especially if you add a few (hand fulls) of the high protein marshmallows!!!
High protein gooeyness!!!!
Review by: Steve on Mon, Apr 11, 2022 3:25 PM
How awesome is it when you have met your protein requirements while having a treat! Easy to make and would suit those who really like the fudge cake consistency. I wouldn't go over the 1/4 water but would increase the cooking by just a few more seconds.
Review by: Debbie on Sun, Apr 3, 2022 3:14 PM
Tasted mushy. Usually everything i by from here is great but the mug cake just didn’t have the texture of a cake. NZPROTEIN REPLY: we're sorry this one didn't work for you. It appears that the odd microwave or mug doesn't work.
Review by: Annalise on Fri, Apr 1, 2022 7:53 PM
I though this was great, needed a little longer in the microwave than the 1 min though
Review by: Emma on Wed, Mar 30, 2022 5:10 PM
These Mug cakes are the best totally enjoyed with no guilty feeling knowing they such a great protein hit as all your products are
Review by: jason on Mon, Mar 21, 2022 7:01 PM
The taste is fine. Just like the double chocolate protein flavour. What I had an issue with is the wetness of the cake. I followed the instructions the first time. water, stir, microwave for 45 seconds. The second time I tried 60 seconds in the microwave, it still came out wet. NZPROTEIN REPLY: We have heard of the odd person with this issue. We think it may be the mug itself or the microwave and we suggest trying in a different mug and microwave next time if possible

Paired with halo ice-cream and equal milk chocolate so good!

I personally couldn't get past the glue type texture and taste of tis one. NZPROTEIN REPLY: you may have made this one wrong - shouldn't be gluey!

Amazing. Tastes better than any other microwave cake I've had plus shipping is fast.

Well done probably your best product. I have been buying these for years because they're virtually a whole meal. I have told many people about it sponsor me please
Review by: Pete on Wed, Sep 22, 2021 4:44 PM
Odd flavour so not something I would buy again
Review by: Anonymous on Wed, Sep 22, 2021 8:03 AM
Delicious is an understatement. I like to undercook it so it's nice and fudgy. My new favourite snack! Much easier than making your own protein mug cake. Fast delivery and service too!
Review by: Lauren on Sat, Aug 28, 2021 12:39 PM
Had an alright taste, but found the texture a bit "gummy", like eating peanut butter from a spoon.
Review by: Belinda on Sat, Aug 28, 2021 10:22 AM
Easy to make, great tasting, and high protein content for what it is. One of my go-to treats.
Review by: Anonymous on Thu, Jul 22, 2021 7:05 PM
Love the texture and convenience of this mug cake. Nice to have a wee treat which isn't too naughty. Was a tad bit to sweet for me though. Overall a great product. Only one I've come across on the market too!
Review by: Payal on Tue, Mar 2, 2021 11:19 PM
Really enjoyed this product, very fudgey and had it with the vanilla protein ice cream....match made in heaven
Review by: Lee-Anne on Sun, Jan 24, 2021 10:33 AM
It’s a good product, if you’re craving something sweet but you don’t want to eat bad. It’s a different texture to an actual mug cake though.
Review by: Anonymous on Tue, Dec 8, 2020 7:15 AM
This is the bomb. If you like chocolate as much as I do then this is something worth having
Review by: Kevin on Tue, Dec 1, 2020 2:05 PM
There are absolutely horrible. Didn't get offered a refund either. Take them off the shelves! NZPROTEIN REPLY: we tried to help you with making these and you didn't even message us back!!!
Review by: Matt on Sat, Nov 7, 2020 8:42 AM
Soooo yummy! It’s like chocolate self saucing pudding in a mug!
Review by: Phoebe on Thu, Sep 24, 2020 8:12 AM
Convenient and tastes good
Review by: Anonymous on Wed, Aug 19, 2020 3:44 AM
I purchased this a while ago with some other bits and pieces but only got around to having this today..... WOW!!! such an amazing mug cake! it is sooooo fudgy, chocolaty, rich and decadent but only .5gr sugar! amazing! really feels like you are having a 'naughty' piece of cake. 33gr of protein! I am definitely ordering more. totally knocks the sweet craving on the head while being totally satisfied and doing you body good at the same time.
Review by: Megan on Thu, Aug 6, 2020 10:44 AM
Tastes so good and delicious you know that there is a protein in the mug but the chocolate overpowers this.
Review by: Camilo on Fri, Mar 27, 2020 9:56 PM
Love this... wierd texture but I still love it. I cook it a bit longer than recommended however. Can't stop at just one!!

Great product for a late night treat that you can get away with since it has a lot of protein. Great with yogurt and some berry's on top!

Tasty goodness
Review by: Colin on Mon, Oct 7, 2019 4:19 PM
Easy and delicious! I have it as a once per week treat.
I hope you are going to make more of these and I'd be interested in buying tubs!
Review by: Serena on Fri, Sep 6, 2019 3:59 PM
I am in love with this product.
Maybe you can sell it in bulk. Like 10 satchels in a box or bag.....
Cause one at a time will definitely not do it for me. its way to yum

Review by: Jay on Thu, Aug 29, 2019 7:36 AM
yum!!! love this mud cake. so rich in flavour.
better than other brands I have tried so I will buy this again. the protein mousse is also really good too!
Review by: Amanda on Wed, Aug 14, 2019 4:58 PM
I have been very impressed with all of the nzprotein products so far and this did not fail to disappoint. It is rich and chocolaty, but a tad gummy.that may be down to the fact I added a bit too much water. Super yummy for a low calorie snack and I love the fact it has added collagen as well
Review by: GC on Tue, Aug 13, 2019 10:13 AM
Takes different amounts of time in different microwaves so just kept going till I got the right consistency but nomnomnom totally my fave craving buster!! Also paired with the berry protein ice-cream = perfection!!!
Review by: Anonymous on Wed, Jul 17, 2019 1:53 PM
Sadly, this was the most revolting thing I've ever had. It leaves an awful chemical aftertaste, it's not even remotely sweet. It ressembles sugarless cake batter with some kind of dusty pea protein thrown in. NZPROTEIN REPLY: these are a very popular product and for good reason. A very small number of people appear to have mugs/microwaves that aren't hot enough or don't allow enough heat through and the product doesn't work. We suggest using a different mug/microwave in such cases.
Review by: Nicole on Tue, Jul 9, 2019 6:32 PM
First product from NZ Protein that I am disappointed with. Followed the steps mentioned in the sachet but the end result was nowhere like a Mug cake. It was runny and tasted horrible.
Review by: Anonymous on Wed, Jun 19, 2019 3:47 PM
So easy and very tasty. Helps fill the gap especially if you crave a treat. Definitely on my "buy again" list
Review by: Carol on Fri, May 3, 2019 12:00 PM
This is the best protein dessert I've ever had.
Review by: David on Sun, Apr 7, 2019 8:29 PM
This is BY FAR the best mug cake I have ever had. And I'm not just talking protein mug cakes, I mean ALL mug cakes. As soon as I took one bite, my skin cleared, birds outside started singing sweetly, my gpa went up three points, and my third eye opened.

For real though, this is rich and the texture is very smooth - unlike the usual protein baking which has a weird chewy texture. This is great, 100% would recommend. Big ups to the cows
