Keto Peanut Butter Cake Bars

My recipe for Keto Peanut Butter Cake Bars is full of peanut butter goodness. It’s thick, soft and chewy in one perfect little keto-friendly treat. 

Years ago I would make a recipe similar to this for my family. Of course, back then it was one very high carb-loaded dessert. That high carb option needed a keto makeover and these easy keto peanut butter bars is the result wanting that craving satisfied.

 

 

This girl has always enjoyed the flavor of peanut butter and if it’s slipped inside a cookie, bar, or cake then I am for sure all in. If you’re anything like me, you will appreciate the bold peanut flavor in this dessert. 

I love how this makes enough for a large crowd. But fear not, because this recipe freezes beautifully so you can certainly tuck them away in your freezer for when you want to satisfy your peanut butter cravings safely. 

This is one of those recipes you can serve to your entire family. Since these low carb cake bars are so good that even those not on a keto diet will enjoy. Don’t you just love giving your family healthy treats that they will actually ask for?

I would describe these as a cross between bars and cake. They are not exactly bars but not exactly cake either, these are more what you would call cake bars.

For a true bar experience, you might try my Keto Peanut Butter Chocolate Chip Bars and my cookies for a Keto Peanut butter cookie recipe that is unmatched. I also have a complete list of Keto Cookies that any cookie lover doing keto would enjoy exploring.

Recently, I made a batch of these to have as a dessert option when I had some family drop-in wanting to test our new ping-pong table. After a few rounds of ping pong, my niece Melissa asked if I had anything sweet to eat. To which I quickly responded by pulling out my large pan of keto-friendly peanut butter bars.

Seeing so many non-keto folks around that pan was a tad intimidating but I thought what better way to test a recipe than with a group of people who rarely if ever have anything ketogenic. 

All I can say is that their ohhhs and awwws proved that it was a winning recipe. And that vote of confidence made my day.

To make these keto peanut butter cake bars you’ll need a few basic keto baking ingredients. My recipe includes creamy peanut butter, eggs, butter, almond flour, and a little whey protein.

If you do not have any whey protein available, that’s not a problem. Just substitute it for more almond flour. I told you this was a simple recipe.

You can, of course, substitute the peanut butter for your favorite nut butter and still have an amazing keto treat. See there I just gave you more options!

These keto peanut butter cake bars have a rich peanuty flavor profile thanks to the generous amount of peanut butter. But do make sure that when choosing your peanut butter, that it’s one that only has peanuts in the ingredients.

I wanted these bars to be moist and I accomplished this by using both butter and cream cheese in the batter. And as far as what flour to use to keep it low in carbs, I went with almond flour. I also added some zero carb protein powder for stability. 

The Sugar-Substitute

When it comes to choosing which sugar-substitute to use for this recipe, I have a few options for you to choose from.

My go-to choice is Lakanto Monk Fruit because it truly is the closest thing to sugar in my book. Not only does it behave like sugar but there is barely any aftertaste. It is a monk fruit and erythritol blend. In this recipe, you can choose to use their granulated or gold option with equally great results.

Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. It’s why it’s a great all-natural sugar-substitute and has zero calories and zero glycemic index.

I’m also partial to  Swerve an erythritol blend. Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures just like sugar.

It’s also a sugar substitute that browns and caramelizes just like sugar. Swerve is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives or flavors.

Swerve is the name brand of Erythritol it’s unlike other sugar alcohols has a 0 % impact on blood sugar.

You could also use the stevia and erythritol-based brand Pyure for these cake bars. But if using Pyure you will want to use 1/2 the amount called for in this recipe since it’s much sweeter.

Lastly, if you can easily find a more natural sugar substitute you can also use Splenda with great success.

You will want to use the Splenda that has a bulking agent. It’s the one that comes in larger bags. I don’t recommend Splenda Bake because it’s actually half sugar half sucralose product and will be too high in carbs to be considered keto-friendly.

I’m not completely sure why fall is my favorite season, especially since it’s really non-existent here in South Florida where I have lived most of my life.

Despite this, I still love everything about what the fall season represents. You know the start of a new school year, pumpkin latte, coming up with a keto peanut butter bar recipe and even the cheesy fake fall leaves in the department stores.

I did warn you that I LOVED everything about this season.

For some reason, I associate peanut butter also with the fall season. Again, maybe it has something to do with all those peanut butter and jelly sandwiches I had as a kid.

If there is one thing I particularly proud of sharing it’s how we combined our Christian faith with the keto diet.   

In case you don’t know, Randy and I came to the keto diet looking at it from a Christian perspective. As believers, we live our entire 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.  I love how supportive and encouraging this group of believers are. It’s exciting to see how people are transforming their lives by combining this lifestyle with the Christian faith. 

The testimonies coming out of our Fittoservegroup is what motivates us to continue to share what we’ve learned.

  12. Store leftovers in the refrigerator for up to 5 days or freeze for up to 3 weeks.

  1. Does it matter which type of whey protein – isolate, concentrate, casein or a combination of someall? I find ones containing casein tend to be less dry. Nice recipe!

    I can’t wait to try this Peanut Butter Extravaganza… it looks like a new fav for me. I would also like to make it for my Keto girlfriend who has a peanut allergy, substituting almond butter and sliced almonds with the melted almond butter drizzle on top….
    What do you think? It seems as though that would work out just fine, right?
    Blessings❣️
