Hey there, welcome back to my blog for another keto product review! I’ve been thinking a lot lately about what makes a diet plan successful and what makes others fail. Keto really works for me because of the way I feel when I eat according to the plan. While some may criticize it to say, “that’s restrictive because you can’t have carby foods,” I prefer to look at it as an opportunity to get really creative with the flavors I already love. I’ll bet you didn’t think you could have pizza, ice cream, and onion rings on keto, right? Well I’m here to tell you it’s totally possible with some creativity and experimentation in the kitchen. You can totally enjoy your favorite foods with keto-friendly ingredients. If you don’t already follow this blog, go ahead and bookmark it (and follow me on Instagram for updates!) so you can totally change your mindset on keto.

Though I fondly refer to these “craving” items as “junk food,” by no means are they filled with junk. When I think of “junk food,” I think of chips, ice cream, fried foods, chocolate, and all things comforting when you’ve had a long day and/or a few beverages. One of those favorite junk foods for me is ice cream. If you’ve been following my social accounts for a while, you know I love a pint of really good keto ice cream. And if you have a Joe Biden-level affinity for the timeless treat as I do, you’re going to want to know about Mammoth Creameries.

Mammoth Creameries is a company I’ve had a keto crush on for a while now. They have great ingredients in their keto custards and their social media kicks ass. Go follow them on IG now if you don’t already. Before I tell you too much about them, I just want to make sure you know they provided these in exchange for a review. That little tidbit doesn’t influence my opinion on them at all. I just want to know sure I’m transparent with you guys about these. I held off on purchasing because of the high price point for this long, so I was absolutely stoked when they messaged me to offer some in exchange for a review. As always, my opinions and thoughts here are 1000% my own and I don’t take talking points from companies. I’ve been keeping it real with you guys since day 1.

So before we start, a big thank you to Mammoth Creameries for sending these over. And now, without further adieu, let’s get into the review.

Who is Mammoth Creameries?

It’s not uncommon for great keto products to grow out of the constraints presented by an illness. Most commonly, I’ve noticed these products are created by people who are Diabetic or pre-Diabetic. Mammoth Creameries falls into that category of products. I share that with you because it’s something that can really benefit you, as a keto product consumer. This means that the founder has paid special attention to the ingredients and their quality to ensure it falls within the parameters of the diet. When other companies make keto versions of their existing products (i.e. Lenny and Larry’s Keto Cookies or Breyer’s Carb Smart ice cream), the ingredients tend to be of poor quality and not so good for those who need to follow a strict keto diet. The ingredients in MC’s keto custards are A1 on the keto standard.

There are currently 4 flavors available: Vanilla Bean, Chocolate, Lemon Buttercream, and Chocolate Peanut Butter. I’ll go through my thoughts on each of these and then I’ll offer a couple of suggestions for additional flavors (in case any of the cool MC people are reading this and looking for ideas)

If you’re trying these for the first time, you need to treat them like keto ice creams that require thaw time before eating. Or, if you’re impatient like me, you need to throw the whole pint in the microwave for 15-30 seconds to warm it a little for scooping.

Vanilla Bean

INGREDIENTS: heavy cream, grass-fed butter, xylitol, egg yolks, natural vanilla extract, vanilla bean seeds, pink himalayan salt.

Flavor profile: Very mild on flavor. I love that this is super creamy and I don’t taste anything eggy that makes this scream “custard” to me. I can see the vanilla bean seeds in the ice cream and I think that gives it a little boost on the “fancy” scale. This one is my second favorite.


INGREDIENTS: cream, xylitol, egg yolks, chocolate liquor, grass-fed butter, cocoa processed with alkali, pure vanilla extract, pink himalayan salt.

Flavor profile: Very, very low on flavor. I taste chocolate but I’m not sure if I like it as much as the Vanilla flavor. It’s reminiscent of semi-sweet hot cocoa, but in a frozen custard form.

Lemon Buttercream

INGREDIENTS: cream, grass-fed butter, xylitol, egg yolks, natural lemon extract, turmeric extract (color), pure vanilla extract, pink himalayan salt, citric acid.

Flavor profile: This is the keto sherbet you’ve been waiting for. This doesn’t remind me of a custard at all – it’s like the most delicious citrus ice cream cake filling I’ve ever had. I use this and some Sprite Zero (you can use seltzer, too) to make one of those delicious “baby shower punch” recipes and it was SO DAMN GOOD. Super light and fluffy. I downed it in like 10 seconds. This is the flavor I’ll be thinking about when I go to sleep at night.

Chocolate Peanut Butter

INGREDIENTS: heavy cream, xylitol, peanut butter (peanuts, peanut oil), chocolate liquor, egg yolks, grass-fed butter, cocoa processed with alkali, natural vanilla extract, pink himalayan salt.

Flavor profile: This is like a very mild Reese’s cup. The thing I like about all of the Mammoth flavors is that they’re just a tad salty. This one has the perfect amount of salt.

Flavor Suggestions

Since the fruity flavor was the star of the show, I’d love to see more of those. I’m thinking strawberry shortcake, raspberry lime, and margarita would be welcome additions. Mammoth could absolutely play off the mocktail theme and do an entire line of keto-friendly custard pints (hold the alcohol).

Also, since we’re staying in our strict-keto lane here, I’m going to get a little weird. Bacon is the perfect, stereotypical keto food. I would love to see a maple bacon flavor show up in the web shop. I haven’t seen anyone else do that one and I would absolutely throw that on one of my sweet breakfast chaffles.

Other Stuff

MC has placed a locator on their website to help you find it in stores near you. I’ve placed a screenshot here of what was near me. Unfortunately, there aren’t any locations in the state, however that can always change if you request it at the right places!

Here’s that screenshot:

Now let’s do one final breakdown before we rate.


  • Formulated by a keto dieter, for keto dieters
  • Excellent ingredients
  • Really smooth texture
  • Light on sweetness
  • Quality shipping materials kept the product cold


  • Flavor is very mild compared to other frozen keto desserts
  • Not available in any stores in my area (Alabama and/or Georgia)
  • Price point is very high compared to other frozen keto desserts

RKF Product Score

Taste: 9/10
The flavors are super mild compared to other frozen keto desserts, HOWEVER, I think that people looking to cut down on their “sweet” consumption will really appreciate that mildness.

Availability: 6/10
Mammoth Creameries has placed its keto custards in a bunch of stores across the United States. Unfortunately, Alabama and Georgia don’t have any (sad face). Their web shop will ship it to you, though, and with really great packaging to ensure it stays frozen.

Necessity: 6/10
Those looking to lower their sweet intake but still enjoy a treat every once in a while will really enjoy these. +1 point for the excellent ingredients.

Cost: 4/10
I’m so torn here, because per calorie, you’re getting a little under 100 calories per $1, which is my usual benchmark. But when I think of frozen treats like this, I have to compare it to the prices of keto ice creams, which have a little less calories overall but drastically different prices. I think the average person is going to compare dollar-for-dollar the volume of ice cream they get and not the actual caloric makeup. For that reason, I’ve given MC a lower rating here. If the ice cream was somewhere in the $8-9 per pint range, I could totally justify the cost. Maybe that’s how much it costs in stores. But paying ~$11/pint online (including shipping) is just too high for the average consumer in my area. I don’t think budget shoppers will try this item at the price point it is online.

Something that could help this rating IMO is emphasizing the value of the included priority overnight shipping. I know that’s gotta be worth like $20 (and with the quality of shipping materials, that’s even more). But it’s mentioned as sort of an afterthought on the product page which makes it easy to miss when customers look to purchase.

Quality: 10/10
Only a few, really great ingredients. That’s it. Nothing bad here.

Branding: 10/10
I have a marketing crush on these guys.

Bottom line: 7.5/10 

Did it knock me out of ketosis? No

Final thoughts: I really love this stuff, but man is it expensive. If you’re not into purchasing products (especially frozen ones) online, then you probably won’t want to buy this. Despite the low marks for cost and availability, though, I’m still a big fan. If this was available locally, I’d buy it as a treat every once in a while. If you can spend $30 on a single steak every once in a while, you can spend $11 on a really good pint of keto-friendly dessert every once in a while, too. It’s about priorities.
