Warm Peanut Butter Brownies

Ready to bake in 5 minutes and no xanthan gum needed.

Growing up, my mom would get after me for dipping my spoon into the peanut butter jar and pulling out a hunk of the stuff. I would sneak off and slowly eat it off the spoon. I still do it today, but no one gets after me.

Except maybe the dogs. I think they want me to give them some. Peanut butter cookies are still my favorite and I will wrestle with anyone for the last bit of peanut butter pie. But these gluten free bars sure are amazing, especially for a peanut “nut” like me!

This is from my Gluten Free Brownies and Bars Cookbook .



Easy, quick and tasty. Make this for dinner tonight. Prep time is 5 minutes max and bake time is about 25 minutes.

Gluten Free Peanut Butter Brownies













1/2 cup creamy peanut butter
1/4 cup butter, softened
1 tsp. gluten free vanilla extract
1 cup packed brown sugar
2 eggs
2/3 cup gluten free flour

Hint: There is no need for xanthan gum in this recipe. The amount of flour used is under one cup. The peanut butter and eggs will keep it together for you. If you have gluten flour that already has gum in it, that’s fine. You just don’t need to add any if your flour doesn’t.

Equipment needed: Bowl, mixer, spatula, 8×8 baking pan, measuring cups and spoons


Preheat the oven to 350 degrees.

Mix together the peanut butter, butter, vanilla and brown sugar in a bowl with an electric mixer. Beat in the eggs one at a time and then mix in the flour. Spread it into a well greased or parchment lined 8×8 baking pan. Bake for 20 to 30 minutes.

Don’t over bake or your brownies will be DRY! If you’re not sure how done is done, poke the center with a toothpick. If you have a few crumbs on your toothpick, good. Better underdone than over done with brownies.

Remove pan from the oven, cool and then spread with Peanut Butter Frosting to really make this an over the top PB delight.ย 

Peanut Butter Frosting

Place 1 cup creamy peanut butter and 1/3 cup of powdered sugar in a bowl and blend together. If it’s too stiff to spread, add a little more powdered sugar until it’s just right.

You could also spread these brownies with Nutella, or change the peanut butter in the frosting with some grape jelly and use that instead. PB and J brownies. Sounds good.

Another idea is to take the brownies unfrosted, cut into squares, place in dessert bowls and top with a scoop of ice cream, chocolate or butterscotch syrup, a squiggle of whipped cream and a maraschino cherry. Cheaper than going to the local ice cream shop.

Happy Baking!

I love my USA baking pans! These pans are made of aluminized steel and excel in superior heat distribution. Usa baking pans also have a nonstick coating that makes it easy to get your brownies right out of the pan without destroying your goodies!! These brownies turned out gooey on the inside while still giving a nice crust along the edge (which is my favorite part). Best part about these baking pans is they are made right here in the United States. Click on the link and see why so many others love this product too!!

    Would these be just as good with non-dairy butter?

      Yes, they would. The flavor will be a little different because butter gives flavor, but they will be still be delicious.

    I thought I was ordering an actual book. I do not have a Kindle. The order #D01-3682702-9056208 needs to be canceled. I would like to order a book if they are available. I am sorry for the mixup.

      Sorry about that. Right now I only have it available on Kindle. You can download Kindle format for your computer or an iPad if you have one.
      If that won’t work, just get in touch with amazon and cancel the order. They will refund it to you. Thanks for trying ๐Ÿ™‚

    My daughter is allergic to wheat, eggs, modified cornstarch & beef. What would you use in place of the eggs? She doesn’t like the flavor of egg replacer. Could you use applesauce?

      Have you tried using the flax meal egg replacer? 1 Tbsp. flax seed meal mixed with 3 Tbsp. of water per egg. Let it sit until it gels and then add with the liquid ingredients. Try that and see if it works for you.

      I know someone who is allergic to chicken eggs, but she can eat duck eggs. Do you know if your daughter can eat duck eggs? You may be able to find them near you – probably not at a grocery store, but from someone who raises ducks.

        Since one egg equals 1/4 cup, just make sure you measure out your eggs. Duck eggs would be fine. Might give a different taste but other than that, go for it.

    Could you use stevia instead of brown sugar?

    • kathy

      Reply Reply October 26, 2015

      You probably could. I would add a little molasses to the recipe because brown sugar has some molasses in it, so you will lose that flavor. Just add a tablespoon or two of molasses and see what happens. I’m sure it will be fine. The big thing with brownies….don’t over bake! Anything else can be adjusted as needed ๐Ÿ™‚

    Thanks for the recipe and I’ll be off to check out your book!

    Can you tell me if these can be made with “natural’ peanut butter or does it have to be made with standard brands like skippy or jiff?

    Thank you


    • kathy

      Reply Reply October 26, 2015

      I’m not sure! I used Skippy brand. Natural are usually stiffer in texture so you made need to add a little less flour if it gets too stiff.
      Try it and see what happens! That’s the fun part. As long as you don’t over bake it I’m sure it will turn out just fine.

    I made these last night, they turned out great! I used 3/4 cup of maple syrup in stead of 1 cup of sugar. I had to bake them a bit longer, I believe it was 35 minutes. Thank you for sharing your recipe.

    Could you use coconut flour?

    • kathy

      Reply Reply November 9, 2015

      You could use coconut flour. I would start with 1/4 cup and try that. If it doesn’t have the right consistency go up to 1/3 cup but I would not do any more that that. I think the 1/4 might be enough.

    will ghee or coconut oil work?
    will soy butter or cashew butter work?
    any gluten free flour? coconut flour? potato flour? oat flour?
    Please advise, thank you

    • kathy

      Reply Reply November 11, 2015

      Yes, ghee would work or coconut oil. You can definitely change out the peanut butter with any nut butter you would like. As for the gluten free flour, any you suggested would work as the amount is under one cup. You could use coconut flour. I would start with 1/4 cup and try that. If it doesn’t have the right consistency go up to 1/3 cup but I would not do any more that that. I think the 1/4 might be enough.
