Are you a fan of chocolate and peanut butter doing keto? Well, these delicious keto peanut butter brownies will satisfy that craving easily.

It’s a recipe for low carb peanut butter brownies because who doesn’t love the combination of peanut butter and chocolate? I mean honestly, these two were meant to be besties and live side by side as far as I am concerned.

Am I wrong? Don’t you agree that certain foods were just destined to go together? It’s as if they bring out the best of one another by enhancing their flavor profiles.

I’ve always been a fan of the combo of chocolate and peanut butter. AND….I don’t see this love of mine changing any time soon.

These keto peanut butter fudge brownies are made extra fudgy with the addition of cream cheese in the peanut butter swirl. Cream cheese makes these peanut butter brownies extra moist and further enhances the flavor of these brownies.

Keto Peanut Butter Fudge Brownies

Do you know that before I made low carb keto a lifestyle, Reese’s Peanut Butter Cups were a regular part of my life? Fast forward, and a real Reese cup hasn’t crossed my lips.

BUT….by no means that I suddenly stopped loving the combination of peanut butter and chocolate.

However, traditional chocolate and peanut butter desserts no longer fit my lifestyle.

So, a new healthier version needed to take its place.

Creating a low carb treat, like these gluten-free peanut butter brownies gave this girl an excuse to enjoy chocolate and peanut butter goodness.

AND…it gives you another easy keto treat to try.

Before I share my keto peanut butter and chocolate brownies with you, let’s talk about the quality of your ingredients.

To begin with, your peanut butter needs to be an all-natural variety. One that has zero sugar added. This will ensure that it’s low in carbs and that doesn’t throw you out of ketosis.

When using an all-natural peanut butter remember to give it a good stir to ensure that all it’s fully incorporated before mixing it into your keto peanut butter swirl brownie batter.

The quality of your chocolate also matters. Personally, I’m pretty partial to Baker’s unsweetened baking chocolate because of its rich chocolate flavor. You get great consistent results each and every time with this brand.

The Best Sugar Substitute For These Keto Brownies

I have several options when it comes to which sweetener you can use in my recipes. I really like Lakanto Monk Fruit because the texture is spot on and because there is barely any aftertaste.  It’s the one sweetener that never gives me an issue.

I’m also partial to Swerve an erythritol blend. Although it does have a cooling aftertaste that some people dislike. Personally, it’s not an issue for me and it’s why I am a fan.

You could also use the stevia and erythritol-based brand Pyure for most of my baked goods. But for some reason, I find that chocolate and stevia do not play well together and generally it produces a greater aftertaste.

It’s also doubly sweeter than most sugar-substitutes you may need to add half the amount the recipe calls for when keto baking

So in the case of this recipe, I wouldn’t recommend it unless you’re familiar with it and it’s not an issue for you. 

Lastly, if you can’t easily find a more natural sugar substitute you can also use Splenda with great success. I know not everyone would agree with me here and I respect that but in my book, it’s still better than regular sugar. 

Can I Substitute Almond Butter For Peanut Butter?

But what if you can’t have peanut butter? Or you’re looking for a way to further reduce the carbs.

Not a problem…. I’ve created this recipe several times with almond butter instead of peanut butter and guess what?  Almond butter also goes amazingly with chocolate.

So, if you have a peanut allergy or don’t include legumes in your diet, don’t let that deter you from this easy keto brownie recipe.

Join Our Jesus And Keto Movement 

Randy and I came to the keto diet looking at it from a Christian perspective. As believers, we live our lives supported by God’s grace.

So when the Holy Spirit led us to combine our Christian faith and the keto diet, we did so in hopes of finding lasting transformation.

Randy had been a diabetic for over 15 years and he was dealing with the consequences of this disease. I was a survivor of the Guillan Barre Syndrome and was fighting fibromyalgia and chronic sciatica.

To say we needed God’s intervention is putting it mildly. When we followed the Holy Spirit’s prompting to we got on the path to real transformation. 

Knowing firsthand the benefits of this decision we have created a closed Christian group that is using the keto diet to transform their lives.  We invite you to join our Private Facebook Group and see if it’s not the key you have been missing.
