Keto Chocolate Peanut Butter 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 bars no longer fit my lifestyle.

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

Creating a low carb treat like these keto 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.

This recipe starts with a peanut butter base and then gets a MASSIVE dose of chocolate with a fudge swirl.

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 Hershey’s Dark cocoa powder because of its rich chocolate flavor. A little goes a long way with this cocoa powder. 

The Sugar Substitute

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 produces a greater aftertaste. It’s also a bit sweeter than most sugar-substitutes you may need to adjust the amounts 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 peanut butter swirl brownies.

Here’s Another Chocolate/Peanut Butter Recipe

If you’re a lover of chocolate and peanut butter, you MUST give my Keto Peanut Butter Fat Bombs recipe also a try.

It’s as close as you’re going to get to a chocolate peanut butter cup candy. Of course with the major difference that they are S-U-P-E-R good for you.

Keto Hack To Stay On Track!

TruBrain Ketone esters

Can I let you in on a little secret? You see I use Trubrain’s ketone esters to stay on track. That’s right because the key to doing keto successfully is to stay the course long-term.

The main difference is that when supplementing with either ketone salts or ketone esters is that your body can use the energy they provide immediately. Whereas with MCT Oil your body must first break down the fatty acids before it can use it as fuel. 

By creating a ketone supplement that uses both esters and salts TruBrain has been able to address the two limitations that made it impossible for the average person to experience the use of ketone esters.

First, the cost has been dramatically reduced making it possible for more people to afford a supplement that has ketone esters and second the flavor is no longer an issue.

Their science team was able to engineer an ideal mix of both raw ketone ester plus ketones that are bound to minerals like potassium, calcium, magnesium, and sodium. 

Doing so has created a supplement that gives you the uptake of ketones so that they can experience quicker while also giving you benefits of being in a state of ketosis for a longer window. Plus the minerals in the product ensures that you are getting the proper electrolytes while supplementing with ketones. 

Stay In Ketosis Easily

Enjoy the benefits of ketosis without the painful discipline required to be in nutritional ketosis. Supplementing with Trubrain ketones is a great solution for those who want to do a keto diet but find it hard to stay in ketosis or who simply want to raise their threshold of carb allowance.

Although supplementing with ketones does not automatically equate to weight loss it can be a tool in your weight loss goals. Mainly because exogenous ketones act as a strong appetite suppressor.

    Made a pecan maple chocolate chip version with a hint of peanut butter (only had 1/4 cup on hand. I tagged you in my Instagram stories

    • Hi Jahmila, the IG pictures are lovely thanks for tag beautiful one and for stopping by to comment.

      Hi Hilda!
      Just made this recipe. It ‘s cooling on a rack right now but the entire house smells so Devine! I do have a question..
      I let it continue to bake for quite a number of min over the maximum time listed. Probably 45 min or more altogether. It’s looking very dark and began to crack on top, but still has a little bit of jiggle to it. I’m guessing they might be like traditional brownies and continue to bake after coming out of the oven.
      Thanks for another winning recipe! The batter alone was phenomenal! Can’t wait to dive in!
