Banana Blondies with Creamy Peanut Butter Frosting

You know, there’s an old saying, “two wrongs don’t make a right”. I wonder what they’d say about two rights? Does that make it wrong? Let’s hope not because today I’m sharing with you something that has two super right things – bananas and peanut butter. That’s what these Banana Blondies with Cream Peanut Butter Frosting are all about. And you know what? If these Banana Blondies are wrong, I’m not so sure I even want to be right.

Easy and delicious Vegan Banana Blondies with Creamy Peanut Butter Frosting - our favorite dessert!

And now I have a quandary for you. If we’re talking about a person and we call them kind of dense, that’s not such a good thing. Right? But if we’re talking about a blondie and we call it dense, we hear groans of pleasure in response.

Sometimes I think too much.

All I know is dense blondies (or brownies for that matter) make for some pretty good eatin’ in my book.

Delicious, fudgy Banana Blondies with super creamy peanut butter frosting. It's SO good!

What I Love About these Banana Blondies

That peanut butter frosting is so perfect on top of these Banana Blondies. Sometimes I like to spread lots of that creamy peanut butter frosting and let it ooze over the sides. And sometimes I like to have it all neat and tidy. I can’t decide which one is best!

Also, these Banana Blondies are sweet, and oh-so-easy to make. Just a few ingredients and around 30 minutes later and you’ve got yourself a decadent dessert that everyone’s gonna swear you spent hours on. (Don’t worry, your secret is safe with me).

I love that this dessert is made with bananas and ground flax meal. Throw in a little protein with the peanut butter, and this is almost a health bar instead of dessert. Again, let’s just keep that part between us. There’s nothing like the word “healthy” to create a total dessert buzzkill.

 

Delicious, moist, Banana Blondies with Peanut Butter Frosting. Make these in less than 30 minutes and enjoy!!

Ingredients
For the Banana Blondies:
  • ½ cup margarine
  • 1 flax egg 1 tbsp ground flax, 1 tbsp corn starch, 3 tbsp water
  • 1 cup light brown sugar
  • ½ cup mashed ripe banana 1 banana mashed with a fork
  • 1 tablespoon vanilla
  • cup all purpose flour
  • ¼ teaspoon salt
For the Creamy Peanut Butter Frosting:
  • ¼ cup creamy peanut butter
  • 2 tablespoons coconut oil
  • 1 cup powdered sugar
  • 2-4 tablespoons plant-based milk almond, soy, etc
Instructions
For the Banana Blondies:
  1. Heat your oven to 350F and line the bottom of an 8X8-inch baking pan with parchment paper or aluminum foil. Spray with a light coating of vegetable spray.
  2. Place the margarine in a microwave-safe mixing bowl and heat in the microwave for about a minute, until melted.
  3. Add the brown sugar, mashed banana, flax egg, and vanilla and stir until well incorporated.
  4. In a separate, small bowl combine the flour and salt and give it a whisk to combine. Add the flour to the banana batter. Stir to combine.
  5. Pour the batter into your prepared pan and bake for 25 minutes, until a toothpick inserted into the middle comes out clean.
  6. In the meantime prepare your Creamy Peanut Butter Frosting.
  7. Allow bars to cool for about 10-15 minutes before removing from the pan and adding the frosting.
For the Creamy Peanut Butter Frosting:
  1. Combine the peanut butter and coconut oil in a medium-size bowl. Stir to combine. If your coconut oil is too firm, it can be helpful to heat it up by placing it in the microwave for about 11 seconds. It doesn't take long!
  2. Add the powdered sugar and stir until you have a crumbly mixture. Add the plant-based milk one tablespoon at a time until you reach a desired, spreadable consistency.

  1. Good gracious these look good!!! Definitely putting them on my To Make list!

  2. Anything with peanut butter seems to win my family over, yum! Especially Peanut Pan Peanut butter (i know, not the best for you, will try the organic kind instead =)

    • I think your family and my family has a lot in common Laura! Honestly, I use the organic peanut butter, but I also buy brands like Jiff and Peter Pan, especially their natural varieties. I find they work really well in recipes like this one. I hope you love these Banana Blondies as much as we do!

  3. These blondies look heavenly! Can’t wait to try this amazing recipe!

  4. These looks scrumptious! Do you think I could substitute almond or coconut flour for the flour, and use xylitol or stevia for the brown sugar? I’m adrenally challenged and the sugar and carbs tempt me so.. but just aren’t good for me. lol

    • These blondies are so moist that I bet you could get by with using either almond or coconut flour. Regarding the sweetener, I could see trying the stevia. But I’ve been into date sugar lately. Have you tried that? Or even coconut sugar. I’m not sure how these impact your condition, so you will have to make that call in the end. Let me know how it goes!

  5. What incredibly and sweetly delicious blondies. I just love the look of them – and all that oozy peanut butter frosting!

    • OMG, Thalia, that oozy peanut butter frosting is the BEST! I could have eaten that with a spoon. Oh wait. I think I did! Oh well, less frosting for the blondies is ok. Right?

  6. Omg Marly, your recipes look fantastic! I can’t wait to try these banana blondies–as well as many other amazing recipes on your website! I’ll let you know how it goes 🙂

  7. I made these last night and they were so good! Excellent recipe 🙂

    • I’m SO glad, Jessica! Thanks so much for coming back to tell me this. I loved this recipe too – so simple and yet so flavorful. XOXO, Marly

  8. Love these! I have really been into baking with bananas lately. Maybe it’s the weather, but banana treats just feel so cozy. Can’t wait to give these a try. That peanut butter frosting is sending me over the edge!
