You would be amazed by what you can give up, lose, or break, and yet still be a person who gets happy over brownies.

– Augusten Burroughs

The history of brownies

There are all sorts of stories about where the brownie originated. Most will agree it’s an American concoction. I’ve read some stories that say they came from a baker forgetting to put the baking soda in a chocolate cake.

In the latter part of the 19th century, smaller portable cakes became the fashion for outdoor activities. Ladies requested desserts that could be eaten al fresco and packed easily.

One such recipe was on behest of Bertha Palmer of the Palmer House Hotel in Chicago. It was 1893, and she wanted a small dessert, yet still cake-like. Why? Well, she wanted to provide a dessert for the ladies attending the World’s Fair.

The Palmer House Hotel is now a Hilton, and to this day you can order “Bertha’s Brownie”. Actually, some claim this to be the first brownie with walnuts and an apricot glaze.

I wonder if the recipe has changed in the past couple hundred years!

How to make low carb peanut butter brownies

I most certainly do like a recipe that is super-simple and quick to throw together. In particular, I like a recipe where you can throw all the ingredients together in a bowl. Then mix them up, and say voílà!

Granted this recipe is not quite that easy, but it’s pretty close. Shall we begin?

First, take out a large bowl. Second, preheat the oven to 350 degrees Fahrenheit, and grease the baking dish with butter or coconut oil.

I like a thicker brownie so I use and 8″ by 8″ glass baking dish. If you prefer a thinner brownie, you can shorten the baking time by 5 minutes and use a 7″ by 11″ pan.

Next, whisk together the melted butter (or coconut oil), peanut butter, vanilla, and powdered sweetener in the large bowl until smooth. Add in the eggs one at a time mixing as you go.

Then, add everything else but the chocolate chips and stir the mixture with a spoon or spatula until it’s all evenly combined and a dough-like consistency.

Add the sugar-free chocolate chips

The last thing before you bake is to mix in the chocolate chips. Make sure to get them evenly spread throughout so you don’t have a big section of chocolate chips and then another part of just plain dough. Not that I’ve done that before or anything! 😉

Now, spread the mixture evenly along the bottom of the greased baking dish. Then put it in the oven for 20-25 minutes or until golden and beautifully baked.

Tip: For the best results cool the uncut brownies on a cooling rack completely before cutting them up into bars.

To frost or not to frost

That is the question.

Keto peanut butter brownies are fabulous plain or topped with keto ice cream. However, if you want to take it up a peanut butter notch make up a batch of Keto Peanut Butter Frosting and spread on top!

It’s not something you’ll regret.

Cut them up into 16 even pieces and serve. Also, they keep well in the freezer for up to a month for emergency afternoon snacks.

I may even be known to warm one up every now and then for a quick breakfast!

A basic rule of baking is that, in general, it’s almost impossible to make an inedible batch of brownies.

Keto brownies: Gooey vs. Cake-like

So let’s all weigh in. Without the scale. Ha!

Kidding, but what is your opinion? Should brownies be gooey or more cake-like? Do you have a preference or consider them two different kinds of dessert?

I’m definitely an ooey-gooey fudgy brownie fan. However, I know plenty of people who would demand, “How could you eat that underbaked dessert?!”

Consequently, I’m going to tell you this. If you prefer a gooey brownie, slightly shorten the bake time on these low carb peanut butter brownies.

On the other hand, if you prefer a more cake-like brownie bake these the full 25 minutes or even more. Of course, you will need to watch so they don’t burn, but add a couple of extra minutes. The top will be more golden, and the brownies more cake-like.

Thanks for reading and sharing peanut butter treat time today! I hope it becomes one of your easy go-to family favorites.

Mine would simply not bake together. What I ended up with makes a great crumble for ice cream, but not does not hold together enough for brownie status.


Friday 26th of July 2019

This is the best keto recipe I have made! I normally despise almond flour recipes, they seem not enough like the real thing normally but this has a perfect texture! I used regular butter and actually used a loaf pan to make them even thicker (still 16 servings though)! I liked them a little tiny under cooked to be more like brownie texture and even my kids loved them!


Sunday 14th of July 2019

I'm sorry they didn't work out for you! To be honest, ingredients can be very different depending on the brand (peanut butter and almond flour brands can both vary) so if the batter is at all crumbly I would add a tablespoon of almond milk at a time until you get the right consistency. Lately, I've come to like them better with butter instead of coconut oil, although I've done both many times. Also, it's important to let these cool almost completely before cutting them into bars. I'm glad you at least got a good ice cream crumble out of it!


Thursday 20th of June 2019

I made these last night. I tasted a lot of coconut than the peanut butter. I am not a big fan of coconut so I was wondering is there a substitute I can use? Could I use butter instead. Plan to make this with maybe more peanut butter and more chocolate and maybe butter instead of coconut oil next time. I bake with coconut floor and it doesn’t bother me but these brownies I felt they were overpowered by the coconut oil. Help!!


Thursday 20th of June 2019

Yes, you can definitely use 1/2 cup of melted butter instead of the coconut oil. Certain coconut oils do have more of a coconut flavor than others so the butter should take care of that for you. Enjoy!

Soooo good! The texture reminded me of a cookie cake!! Current plan is to remake this in the larger dish to get it thinner and top with a keto ice cream and make it into an ice cream cake!


Wednesday 22nd of May 2019

Sounds fabulous! I may have to give the keto ice cream idea a try too! I'm glad you liked it.


Thursday 11th of April 2019

Thanks for sharing! Do they keep long?


Thursday 11th of April 2019

I tend to keep them in the fridge in an airtight container, as they can dry out if left out too long. To be honest, they generally don't last long at our house, but I would say they keep up to a week in the fridge. If you want to keep them longer I'd put them in the freezer (up to a month) and get them out one at a time.


Thursday 11th of April 2019

These look so good! It is a nice twist on the classic!
