Carbs in Traditional Peanut Butter Frozen Yogurt

According to the app Cronometer, the Publix brand of premium peanut butter cup frozen yogurt has 23 grams of total carbs in 2/3 cup. That’s high for such a small serving plus it has 19 grams of sugar.

This is not something to indulge in on a ketogenic diet or even a low carb diet if you don’t want to spike blood glucose.

Pro Chef Tips

#1 Use Full-Fat Greek yogurt.
Full-fat yogurt contributes to the creamy texture and richer mouthfeel essential for frozen yogurt. Low-fat versions tend to be icy and less satisfying once frozen.

#2 Chill the mixture before freezing.
Letting your yogurt and peanut butter blend chill in the fridge for at least an hour enhances the final texture when you freeze it. This step helps develop a smoother consistency and reduces ice crystal formation.

#3 Stir during freezing.
If you don’t have an ice cream maker, stir the mixture every 30 minutes as it freezes. This mimics churning, breaking up ice crystals and keeping the yogurt silky smooth.

#4 Measure sweetener carefully.
Since sugar alternatives can be much sweeter than sugar, add them gradually and taste to avoid over-sweetening. A perfectly balanced sweetness will highlight the natural peanut flavor without overshadowing it.

#5 Store in airtight containers.
Prevent freezer burn and flavor loss by storing your frozen yogurt in airtight containers. Press plastic wrap directly onto the surface before sealing to keep it fresh longer.

Flavor Boosters

​Toast Peanuts
Top this keto frozen yogurt with some peanuts for crunch. Lightly toasting peanuts intensifies their natural flavor and adds a hint of smokiness to the frozen yogurt.

Add a Pinch of Sea Salt
A small amount of sea salt enhances the sweetness and deepens the overall peanut butter powder flavor, balancing the profile beautifully.

Mix in a Touch of Cinnamon or Nutmeg
Delicate spices can bring warmth and complexity, making the frozen yogurt feel cozy and inviting.

Troubleshooting Common Problems 

​Frozen Yogurt is Too Hard
This can happen if there’s not enough fat or sugar substitute to keep it smooth. Try adding a bit more full-fat yogurt or a teaspoon of alcohol like vodka to soften the texture. Also using a liquid sweetener like liquid or powdered Allulose can help the frozen yogurt not freeze rock solid hard.

Grainy or Icy Texture
Stir the mixture regularly while freezing if not using an ice cream machine to prevent ice crystals from forming. Using an ice cream maker, Ninja Creami can greatly improve creaminess.

Too Sweet or Not Sweet Enough
Sweeteners vary in intensity—add gradually and taste test as you go. Remember, flavors mellow once frozen, so aim for slightly sweeter than you’d want initially. Use my Sweetener Guide & Conversion Chart to help you decide how much to use.

Peanut Butter Overpowers Flavor
Balance strong peanut butter with a touch more vanilla or sea salt, to avoid bitterness.

Yogurt Separation After Freezing
Use full-fat yogurt and mix ingredients thoroughly to prevent separation. Avoid refreezing thawed frozen yogurt as it can worsen texture.

Freezing Leftovers

Store leftover frozen yogurt in an airtight container or freezer-safe container to prevent freezer burn. Press plastic wrap over the surface before sealing to keep it fresh.

Frozen, it will keep well for up to 2 weeks; beyond that, texture may deteriorate.

I’d recommend using a glass container or another microwave-safe bowl, (avoid plastic as that can leash harmful chemicals into your food)  then you can microwave the frozen yogurt from the freezer for just 15 seconds to soften and enjoy. 

Can I use powdered peanut butter instead of peanut protein powder?

Yes, powdered peanut butter is lower in fat and calories but may create a less creamy texture. You might need to add a bit more yogurt or cream to balance consistency.

Can I make this recipe without an ice cream maker?

Yes, stirring the mixture while freezing helps maintain creaminess, mimicking an ice cream maker’s function. But for best results I do recommend using a Ninja Creami.

You could just blend up the ingredients in a food processor or high-speed blender and pour into a popsicle mold for a yummy keto ice cream frozen bar. 

Can I use regular peanut butter instead of peanut protein powder?

If you want to use natural peanut butter that doesn’t contain anything else but peanuts and salt, you can do that.

Please note that the nutritional information I have below on the printable recipe card will change and it will add more calories and more fat. 

Can I make this Nut Free?

Yes if you have a peanut allergy, feel free to swap the peanut butter protein powder I used for something else like vanilla whey protein powder or strawberry whey protein powder and add in some fresh berries. 

​Can I replace plain Greek yogurt with cottage cheese?

Yes, you can swap the plain Greek yogurt I used with cottage cheese if you prefer.

Can I use Low Fat Greek Yogurt?

I don’t recommend it as I did test with low fat yogurt and found it to be unsatisfying in my opinion.
