Fudgy Flourless Halloween Brownies

The fudgiest, flourless, brownies you could ever dream of! When I baked these I could not believe how fudgy they were for only 98 calories a piece!

There is another benefit to these brownies, there is no flour, so if you are gluten free these are going to become a dessert staple!

So you may ask, how can you make brownies without flour? You use nut butter! As we all know, my favorite nut butter is Nerdy Nuts, so of course I used that. I used Dirt Cup, which is a chocolate peanut butter to begin with so it was a great brownie ingredient. But with that being said you do not need to use chocolate peanut butter… I would use Nerdy Nuts because it’s amazing.. But seriously any peanut butter would work, or almond butter! 

Let’s get into the ingredients for the fudgy flourless halloween brownies:

Whole Eggs: whole eggs are necessary for this recipe, it will make a difference! You can try with just liquid egg whites but I think they will cook flat!

Light Butter: I used Brummel and Brown light butter, I really like this spread because it is made with greek yogurt and vegetable oil! And it tastes the best in my opinion.

Peanut Butter: As I noted above, I used Nerdy Nuts Dirt Cup, which is a chocolate peanut butter. If you have not tried Nerdy Nuts you need to, but if you do not have it on hand, then using regular peanut butter, or almond butter. 

Coconut Sugar: I love baking with coconut sugar, it is equivalent to table sugar in terms of measurements, and it has a brown caramel flavor to it which makes every recipe better! If you do not have this I would try and use brown sugar, or Swerve brown sugar.

Unsweetened Cocoa Powder: Hershey’s will work but I used a little higher quality brand that was also organic. Not being snooty but these things make a difference especially with brownies!

Sugar Free Maple Syrup: I like the Maple Grove Farm brand, I find it does not have much of an aftertaste! If you do not have this you can use honey or pure maple syrup.

Baking Soda and Salt: You will need both of these ingredients for the fudgy brownies!

Festive Sprinkles: I made these in October around Halloween, so I used cute halloween sprinkles, decorate these for whatever occasion you would like.

These brownies are super easy to make, I cut them up smaller into 16 squares, if you wanted a larger brownie you could cut them into 12, either way, I know you are going to love these.

For ease of making these brownies, I highly recommend that you use an electric mixer, the peanut butter is difficult to handle with just a hand mixer. 

I used a KitchenAid mixer, but you can also use an electric hand mixer, as I said this will make the baking process way more feasible… trust me!

Frequently Asked Questions:

How do you make brownies more fudgy?

When it comes to baking brownies, the more oil, the more fudgy the brownie! So, since the main ingredient of these brownies is peanut butter, this offers a lot of the oils, you also get fat from the light butter, and the yolks of the eggs.

Can you make brownies healthy and low calorie?

These brownies are proof that lower calorie brownies with limited ingredients can taste amazing and can be easy to make! They are also very cute and festive but you do not need to add the halloween sprinkles.. You can add Christmas sprinkles, or even birthday sprinkles and candles!

Are the fudgy flourless halloween brownies gluten free?

These brownies are gluten free, there are not added grains or flour. If you like a cakey brownie, have no fear, these are not extremely dense to the point where they taste like fudge, they still have a little sponge to them. Give them a try.

How do you know when fudgy brownies are done?

These brownies are thick in terms of the batter, they do take some time to bake but you do not want to over bake them! I baked mine for 25 minutes and constantly checked on them by inserting a toothpick and taking them out of the oven when the tooth pick was mostly clean. Keep in mind they are fudgy, and they will bake more as they cool.

Why are my brownies still gooey?

These brownies are gooey, and as I noted above and will take longer to cook in the center, check them with a toothpick to make sure they do not over-bake. They should no longer be runny in the center.
