Chocolate and peanut butter

Personally, peanuts and peanut butter quickly can become an addiction so I’ve had to limit buying giant jars of peanuts. I’ve found one of the best treats for me personally is a chocolate peanut butter cup. Peanut butter frosting (no powdered sugar) came about as a twist on the same theme.

What is the perfect reward or birthday treat? I can’t think of a better one than a keto peanut butter frosting on keto chocolate cupcakes. Yes, please!

Enemy giants moved toward the breach, and Tyson picked up the fallen warrior’s club. He yelled something to his fellow blacksmiths—probably “For Poseidon!”—but with his mouth was full of peanut butter it sounded like, “PUH PTEH BUN!” His brethren all grabbed hammers and chisels, yelled, “PEANUT BUTTER!” and charged behind Tyson into battle.

Are peanuts low carb and keto-friendly?

First of all, what are peanuts?

Peanuts are not tree nuts but a legume. As a legume, they’re in the same family as lentils, beans, and soy. Also, because peanuts are legumes, this means they have more sugar than tree nuts. They are high-fat and a good source of protein.

What else? Well, I’m glad you asked! Actually, peanuts are low carb. They have 6 carbs in one-fourth of a cup with 2 grams dietary fiber, which would equal 4 net carbs (per myfitnesspal.com). They’re also high in vitamins and minerals.

It sounds almost too good to be true, and for quite a while peanuts were my go-to quick snack. However, as with anything, you can have too much of a good thing. I’ve always had a snacking problem, and a snack high in fat and calories (not to mention some sugar) must be portioned.

Peanuts and peanut butter can definitely be enjoyed on a keto diet, but in moderation. Nowadays, I like to use peanut butter as a treat or reward rather than an everyday snack. 

How important is it to choose organic peanuts or peanut butter?

As much as possible, it’s important to buy organic and put the best foods in your body. 

In my opinion, it’s even more important to buy organic peanut butter and peanuts. Why? Peanuts are grown underground with a soft shell that absorbs. 

What does it absorb? Pesticides. Many different forms are commonly used on peanuts. In addition, peanuts are rotated on fields with cotton plants which are often sprayed with the herbicide glyphosate (aka Monsanto’s Roundup) [1].

Even if some of the pesticides are considered “safe”, I prefer to avoid them as much as possible. Therefore, I buy organic and the best quality I can find. What’s the best low carb peanut butter? Read more about the best keto peanut butter options.

To make keto peanut butter frosting you’ll need:

• medium or large-sized bowl
• a spatula
• measuring cups and spoons
• hand-held or standing mixer
• piping bag and tips or a gallon zipper bag

I’m going to live until I die, and everything in between is just another excuse to eat peanut butter.

Ingredients in low carb peanut butter frosting

• 8 oz cream cheese (room temperature)
• ⅔ cup natural peanut butter (sugar-free)
• ⅔ cup powdered sweetener, (such as Swerve Confectioners)
• 1 tsp vanilla extract
• ½ cup heavy cream

When it comes to ingredients, I like to use as fresh and natural as possible. I’ve had some comments on why don’t you make a cool whip peanut butter frosting? Um, no. We definitely want to avoid sugar and any unnecessary added ingredients in our frosting!

Fresh cream and organic is the way to go!

How to make keto peanut butter frosting without powdered sugar

I absolutely love how easy it is to make keto peanut butter icing without butter. Because of the containers of frosting in the grocery store that are so easy to grab and go, we forget frosting’s not difficult to make. In fact, I think it’s one of those things built up in your head as too much trouble, especially when you haven’t tried it before.

Therefore, on a keto diet, it’s pleasantly surprising to find frosting so easy to make. Perhaps the most difficult part of this entire recipe is getting all the ingredients out and letting them come to room temperature.

Once all the ingredients are ready, measure them out and put each one in the same large bowl. Then use a standing or hand mixer to completely blend everything together evenly for two to three minutes.

Be sure to mix it for a good amount of time to whip up the cream and other ingredients for a good-textured frosting. 

Next, after it’s all completely smooth, judge whether or not it’s the right consistency. If it’s too hard, add an additional tablespoon of cream and mix it in until the frosting is as you’d like.

How to store keto peanut butter frosting

After you’ve determined the texture of the frosting is perfect, it can be used immediately. Put it on Keto Chocolate Cupcakes or Low Carb Peanut Butter Brownies!

Or, if you’d like to store it to use later, spoon it in an airtight container, and it can be kept in the refrigerator for up to one week.

If you’d like to freeze it, I would say keep it in the freezer for up to one month before using it. I doubt it will last that long! Wink. 

Variations on keto peanut butter frosting

There are many ways to vary this near perfect frosting should you wish.

1. Almond butter icing: If you wish to make an almond butter frosting, simply switch out a good sugar free almond butter for the peanut butter. This makes a delightful almost keto buttercream frosting.
2. Chocolate almond butter frosting: Simply switch out the peanut butter with almond butter and add 1/4 cup of cocoa powder. If it becomes too thick, add two tablespoons of unsweetened almond milk and mix, continuing until you reach the desired spreadable consistency.

Play around with the ingredients and flavors! It’s fun to add extracts like lemon or almond to your almond buttercream frosting!

How to use keto peanut butter icing without powdered sugar

While is incredibly easy to eat keto peanut butter frosting with a spoon out of a bowl, again I advise portion control. Lol! 

There are so many options for this delicious keto frosting without powdered sugar, and I highly recommend it on my low carb peanut butter brownies seen here:

What else? The possibilities are endless! Keto chocolate cupcakes, keto flourless chocolate cake, as a keto cake filling, or the frosting for the perfect keto birthday cake!
