Peanut butter brownies are rich, delicious, crispy and buttery brownies with peanut butter filling and peanut butter chips in just 45 minutes!

Don’t get me wrong, chocolate brownies are amazing (look up my Fudge Iced BrowniesSalted Caramel Brownies or S’mores Brownies for proof), but sometimes you have to try something new.

 Peanut butter brownies are the rich, delicious dessert that you didn’t know you needed in your life. People seriously love brownies, not matter the size, shape or flavor. To prove my point, America has not one, not two, but three holidays dedicated to this delicious dessert.

For more delicious peanut butter desserts, next time you should try my recipes for Peanut Butter Fudge, Peanut Butter Cup Cookies or classic Peanut Butter Cookies.


  1. Preheat the oven to 350 and grease a 9×13 inch pan.
  2. Cream together peanut butter, butter and sugars until light and fluffy.
  3. Add in eggs then dry ingredients.
  4. Add in peanut butter chips then put into baking dish.
  5. Bake for 30 minutes.

For a delicious dessert, serve up the peanut butter brownies with a scoop of homemade Vanilla Ice Cream or a dollop of homemade Whipped Cream.

Top of Peanut Butter BrownieVARIATIONS

  • Chocolate peanut butter brownies: for a brownie that tastes like a giant peanut butter cup, add some cocoa powder to the mixture before you bake it. For a marbled effect that will give you peanut butter swirl brownies, stir chocolate chips into the batter.
  • Jam/Jelly: Add dollops of your favorite jam or jelly into the batter and swirl to make a peanut butter and jelly bar.
  • Powdered sugar: sprinkle over the top of your brownies to give them a high end bakery look.
  • Gluten free: for gluten free brownies, replace the all purpose flour with almond flour and adjust the cooking time.
  • Nuts: instead of using creamy peanut butter, use chunky. This will give you brownies with chopped nuts already mixed in for no extra work. You can also crush up some peanuts to dust on the top as a garnish.

Fun Facts: The original recipes for brownies had no chocolate in them, so one guess is that the molasses used in the original recipe dyed the dessert a deep golden brown.

December 8th is National Brownie Day, January 22 is National Blonde Brownie Day and February 10th is National Have a Brownie Day. If that didn’t convince you, the biggest brownie ever made was 3,000 lbs and was made 850 lbs of sugar, 500 lbs of butter, 750 lbs of chocolate chips and 500 lbs of all purpose flour.

If you want to try something a little lighter than a 3,000 lb chocolatey brownie, try my recipe for light, delicious peanut butter brownies that are perfect for parties, brunch or just for a treat with a cup of coffee.

Peanut Butter Brownie Tips:

If you’re going for a particular consistency in your brownie, here are some helpful tips.

  • Cake brownies: if you want the brownies to be extra light and fluffy, use less flour and no baking soda. Be a little careful because this will alter the cooking time slightly. You can also use melted butter to make the brownies denser.
  • Fudgy brownies: to make brownies that are essentially peanut butter fudge, use more butter and less flour.
  • Chewy brownies: if you want your brownies to have a chewier texture, use more eggs and more peanut butter.

How to Store Peanut Butter Brownies:

  • Serve: brownies are okay at room temperature for about 3 days before they start getting really stale.
  • Store: put your brownies in the fridge to keep them moist longer. They will still start to get gross at the 4 day mark though.
  • Freeze: brownies stay frozen really well. You can freeze them for up to 3 months and they’ll thaw out perfectly.

  1. Peanut but is my absolute favorite and these sound incredible! Do you have any good egg replacement ideas that I could use in this recipe?

    1. Though I haven’t tested it with this recipe, you could try replacing the eggs with 1/2 cup of mashed banana, applesauce or ground flax seed mixed with water. I’d love to know how it turns out if you decide to try. Thanks!

  2. The instructions do not say anything about vanilla yet it is listed in ingredients. I just realized I never used the vanilla after I put it in the oven. Hope it’s not really needed.

    1. Oh no, sorry about that. It just adds a bit of sweetness to them. I hope you still enjoyed them. I did edit the recipe card to include it in with the eggs. Thanks for letting me know.

  3. I only have a question, Do you use all purpose flour or self rising flour? It has been a while since I made these and I don’t know which I used.

  4. These turned out amazing!! I added one extra egg and 1/2 cup more of peanut butter and they were the perfect, chewy consistency. Definitely saving this recipe!

  5. Is there any way I can use natural peanut butter? I have a few bottles I need to use up. Here are the ingredients: peanuts, wildflower honey, organic coconut oil and sea salt.

    I hope I can. Please let me know!
