Ingredients needed to make a gluten-free brownie skillet

The ingredients needed for this delicious gooey and fudgy banana brownie recipe are all wholesome, clean, and really good for you! You will need:

Wet Ingredients

Ripe Bananas or Sweet Potato Puree
Ripe bananas and sweet potato puree are naturally sweet, so you don’t need much more added sugar to this recipe.

Almond Butter
For nuttiness, gooeyness, fat, and moisture. I prefer a smooth almond butter like this one, but hey, you do you.

To bind and make the brownie moist, use room-temperature eggs. 

Dry ingredients

Cacao Powder
You can use unsweetened cocoa powder as well if that’s what you have on hand.

Chocolate Chips
Both on top and in the batter. Does anyone else agree with the more the better when it comes to chocolate?

Coconut Sugar (Optional)
If you are using really ripe brown bananas I don’t think you necessarily need to add any sugar. But sometimes, when I really crave something sweeter or the bananas aren’t sweet enough, I will add 2 -3 tbsp of coconut sugar (which is totally paleo-friendly) to this banana brownie recipe.

Baking soda
Baking soda just to give the eggs a little help in puffing up the brownie skillet.

Sea Salt
A sprinkle of salt in the batter will enhance all the chocolate flavor. I wouldn’t be mad if you sprinkled some flakey sea salt on top as well.

This brownie skillet is flourless and gluten-free

What started as an accident resulted in the best kind of brownie. 

Once I simply forgot to add almond flour to my paleo brownie and halfway through baking time I realized my mistake. But you know what?

It might have been the best brownie I had made to that day! 

So simply put, brownies (most of them) don’t need any flour! Especially if you like a gooey brownie like I do, you can most likely skip the flour.

Not using any flour only makes this rich and decadent dessert even denser and gooey, which is exactly what we want in a brownie!

Also, no flour means that my brownie recipe is gluten-free, grain-free, paleo, and keto-compliant as well! 

How to make Cast Iron Skillet Brownies

on the first bowl you can see smooth almond butter, eggs and mashed bananas and in the second bowl the ingredients are mixed together

If using the banana brownie recipe, in a large bowl, mash ripe bananas either with a fork or a hand mixer.

Then, add almond butter and eggs to the mashed bananas and mix until smooth and even.

Lastly, pour into a greased cast-iron skillet, top with more chocolate chips.

Then, gently fold in chocolate chips into the brownie batter.

Bake and enjoy!


Tips on making the best gooey ooey brownie skillet

This recipe is so easy to make that I almost want to call it fool-proof.

Here are a few tips to make the best brownie skillet!

  1. Under-bake the brownie skillet for an ooey-gooey result.
  2. Use room temperature eggs. The batter will mix better, the brownie will bake more evenly, and the bake time will be more exact. 
  3. Swirl some nut butter after pouring the batter into the skillet. It will look so pretty! 
  4. Sprinkle some flaky sea salt on top, it really compliments the chocolate brownie so well.


Some Ideas to enjoy this chocolate brownie skillet

Doesn’t it look so festive to serve the decadent brownie straight out of the skillet? 

And of course, there are so many ways you could serve this rich and gluten-free dessert.

Some of my favorite ways are:

  • Serve the brownie skillet warm with a few scoops of vanilla ice cream
  • Drizzle more nut butter and chocolate chips on top
  • Drizzle with melted chocolate or maple syrup
  • Enjoy the brownie skillet with a big glass of cold milk
  • Sprinkle some powdered sugar and/or whipped coconut cream
  • For a refreshing dessert, serve with whipped full-fat yogurt and fresh raspberries


Substitution Ideas You can Try

Swap out the almond butter for peanut butter for a yummy twist, or try sun butter if wanting to stay nut-free.  

If you want to make this brownie skillet dessert low carb, choose the Gooey Paleo Pumpkin Brownies recipe and use keto-friendly sweetener or skip the coconut sugar altogether.

Try any of my brownie recipes mentioned above to switch this cast-iron recipe up a bit. You can’t go wrong with either. 

Want to make this brownie vegan? Use flax eggs instead of real eggs. To make a “flax egg”, simply mix 1 tbsp of ground flax seeds with 2 tbsp of water and let sit for a few minutes. For this recipe, you will need two flax “eggs”. 

Storing Brownie Skillet (without the Skillet)

For convenient reasons, this brownie skillet will be best served when it is still warm and straight out of the skillet.

However, you can store this brownie in the fridge for up to 5 days – if these amazing brownies can last that long… 

And yes, you can freeze it too! I would suggest that you first try to take it out from the skillet and individually wrap portion-sized pieces in plastic.

To defrost, heat the individual brownie pieces in the microwave for 30-40 seconds or let them thaw on the countertop for 10 to 20 minutes. 

Now, let’s start baking!
