I don’t know about you, but I’ve always got a sweet tooth. The problem is I follow a ketogenic diet, low carbs, no sugars, so my choices are far and few in between. I came upon this FitBake vanilla buttercream frosting online and I couldn’t wait to try it because I had one question: does it taste good? Frosting hadn’t been on my plate in a long time. This one changed that.
Quick Verdict
A spoonful straight from the tub got me through a late-night sweet craving with zero net carbs. This FitBake vanilla buttercream frosting is the creamiest sugar-free frosting I’ve had, and it’s become one of my go-tos on keto.
Buy if you:
- Follow keto or low carb and your sweet options are far and few in between
- Want a spoonful treat to get through a late-night sugar craving
- Like smoothing frosting over a fresh strawberry as dessert
- Occasionally frost keto cupcakes and want something ready to use
Skip if you:
- Can’t handle intense sweetness, this is very sweet on the spoon
- Avoid erythritol and sugar alcohols entirely
- Want a huge tub, it’s a single 8oz jar
| Flavor | Vanilla buttercream (also in chocolate, cream cheese) |
|---|---|

| Calories | 90 per serving |
| Sweeteners | Monk fruit extract + erythritol |
| Size | 8 oz jar |
| Diet fit | Keto, Atkins, Paleo, gluten free |
I Hadn’t Had Frosting in a Long Time Until This
Zero Net Carbs, and Here’s How the Label Actually Works
The label reads four grams of total carbs, but every one comes from the erythritol. Subtract the sugar alcohol and you land at zero net carbs, no sugar, no added sweetness in the way that spikes you. The front of the jar says zero sugars and that’s what let it fit my keto diet in the first place. It’s sweetened with monk fruit and erythritol, 90 calories per serving, and it comes in an 8oz jar.
That math is the whole reason this works for me. A single frosted cupcake from a bakery can run 30-plus grams of carbs before you even count the cake. This jar is zero net carbs per serving, so I can hit a spoonful at 10pm and wake up still in ketosis.
I Pulled Off the Lid and It Looked Like Whipped Cream
This is one of the creamiest sugar-free frostings I’ve used, it looks like whipped cream but spreads like buttercream on cupcakes. I grabbed my little spoon and dug in, and the creamy texture was instantly obvious.
Taste? Totally delicious and very sweet. A spoonful is extremely sweet and that’s all I need. If I’m trying to get through the night and I’m just craving something sweet, a spoonful does the job. This has been a game changer for me.
The move I keep coming back to: I grab a larger fresh strawberry and smooth this vanilla buttercream frosting right on top. Now I’ve got the sweetness of the frosting on the strawberry, and that has been phenomenal. It’s my favorite way to eat it.
The Sweetness Is Strong, Pace Yourself
A spoonful is extremely sweet, and that cuts both ways. It satisfies a craving fast, which I love, but it also means you don’t want to plow through half the jar in one sitting. A little goes a long way here. If you’re someone who likes a mellow, barely-sweet dessert, the intensity might catch you off guard the first time. I treat it as a small controlled hit rather than a bowl of ice cream, and that’s exactly why it fits my diet instead of derailing it.

Who This Vanilla Buttercream Frosting Is For
Buy this if you’re on keto and your late-night dessert options currently top out at a handful of nuts. It’s also the right call if you bake keto cupcakes a few times a month and don’t want to spend 20 minutes making buttercream from scratch. Skip it if you need a large-batch frosting, eight ounces disappears fast once you’re eating it by the spoonful.
Vanilla vs. the Chocolate and Cream Cheese Versions
All three flavors, vanilla buttercream, chocolate, and cream cheese, run the same zero-net-carb setup, so the choice is purely about taste. Start with vanilla: it’s the most versatile, works on cupcakes, strawberries, and straight off the spoon. Cream cheese is my close second, sharper and a little less sweet, which actually makes it easier to pace yourself. Chocolate I’d try last; the vanilla and cream cheese versions are harder to put down.
How I’d Use It, and One Thing to Remember
Keep it at room temperature and stir before you use it. Cold makes it harder to spread, so if the texture feels stiff, that’s usually a temperature thing, not the frosting. My advice: don’t treat it like a snack you graze on. A spoonful, or a smear on a strawberry, is the sweet spot. Use it that way and it stays a guilt-free treat that fits your macros. Overdo it and the calories and sugar alcohol add up.
Pros
- Zero net carbs, no added sugar, 90 calories per serving
- Creamiest sugar-free frosting I’ve had, looks like whipped cream
- Very sweet, so a small spoonful kills a craving fast
- Spreads very well on cupcakes and smooths great over strawberries
- Ready to use, no scratch mixing, and comes in three flavors
Cons
- Very sweet on the spoon, can be too intense if you like mellow desserts
- Uses erythritol, which not everyone tolerates well
- Only an 8oz jar, small if you bake a lot
Frequently Asked Questions
Is FitBake frosting really zero net carbs?
Yes. The label shows four grams of total carbs, but they all come from erythritol. Subtract the sugar alcohol and you’re at zero net carbs with no added sugar.
Does it have an artificial sweetener aftertaste?
Not a chemical one for me. It’s sweetened with monk fruit and erythritol, and it tastes sweet and creamy rather than fake. The main thing to know is that it’s strongly sweet, so a little goes a long way.
Can you eat it straight from the jar?
Yes, and that’s how I use it most. A spoonful straight from the tub is my go-to when I’m craving something sweet late at night. You don’t need to bake anything to enjoy it.
Why is my frosting hard to spread?
Cold temperatures stiffen it up. Store it at room temperature and stir well before each use to get that smooth, creamy texture back. Warmer conditions make it spread more easily.
How many flavors does FitBake frosting come in?
Three that I know of: vanilla buttercream, chocolate, and cream cheese. The cream cheese is one of my favorites alongside the vanilla, so it’s worth trying more than one.
Does it work for a low carb vanilla buttercream cake?
Yes, it’s designed to frost keto cakes, cupcakes, and cookies. It spreads well on cupcakes when I use it that way, though I mostly eat it by the spoonful or on fruit.
Is it gluten free and paleo friendly?
Yes. It’s made with gluten free ingredients and fits keto, Atkins, and paleo diets. That’s a big part of why it works for my low carb lifestyle.
How should I store it after opening?
Keep it at room temperature and give it a stir before each use. That keeps the texture smooth and easy to spread, since chilling it makes it stiffer to work with.
