PB2 Flourless Chocolate Brownies

My husband and daughter love when I make a a new batch of brownies. Some of their favorites are these Cheesecake Brownies Zucchini Brownies, and these Flour-less Black Bean Brownies. When I played around with this recipe, we were pleasantly surprised with the outcome! The texture is somewhere in between a chocolate cake consistency and a fudgy brownie, they really hit the spot if you’re craving chocolate.

PB2 Chocolate Brownies

I’m not a baker. Baking is an edible science that requires accuracy and precision. It requires the perfect balance between flours, leaveners, fats, and liquids. When I bake, I feel more like a mad scientist because I break all the rules. So when something actually works and turns out awesome, I’ll be honest, I’m often surprised! These brownies are the perfect example – no flour, no oil or butter, but they are amazing (happy dance)! And the best part, you don’t need a fancy mixer. I mixed this all by hand in a large bowl with a whisk and a spatula.

If you’ve never heard of PB2 (affil link), it’s basically a powdered peanut butter with 85% less fat. You add a little water to make it a spreadable peanut butter. I personally prefer real peanut butter if I’m spreading it on toast, but for baking and adding to smoothies, PB2 is excellent. I used to buy it on Amazon, but now I see it in my local supermarket.

Variations and Tips

  • To Make Them Dairy Free – They also happen to be gluten-free, and if you use dairy-free chips they can be dairy-free as well.
  • Don’t like honey? Swap it with maple or agave syrup.
  • Reduce the sugar more by using Lily’s Chocolate Chips!
  • Nut Free Brownies – If you have nut allergies however, these are not for you. Make these Amazing Flourless Brownies instead as a nut-free option. They are made with black beans instead of flour but I swear, you’ll never know!

  1. Thank you for the recipe!

    In my case it came out quite dry but I believe that is because I replaced the chocolate chips with walnuts! 
    So if anyone is looking to leave out the chocolate chips, be careful and maybe try to make up for the moisture with something else.

    If @skinnytaste, you’ve encountered this issue because, would appreciate your suggestion! 

    Thank you,

  2. I made this yesterday, and these are the best brownies I’ve ever made! Rich, gooey and a total chocolate fix. You don’t miss the sugar or flour at all. Absolutely delicious!

  3. Just ok. A little dry and didn’t taste like peanut butter to me, so seems like an expensive ingredient when it doesn’t add any peanut butter flavor.

    I just made these! They are fantastic! The only thing I did different was I do not like honey so I replaced it with blackstrap molasses! 

  5. Just made these in a mini heart shaped pan for Valentine’s  Day, not sure what I did wrong but these were inedible. Followed recipe exactly, using pb2 powder and all other ingredients. I’ve never had a Skinnytaste recipe not be delicious, so I’m very surprised. My kids even spit them out in the garbage. The flavors were terrible with a very strange salty almost baking soda flavor. 

  6. Amazing  stuff – peanut buttery, fudgy, and delicious. You can’t tell is not the full day kind. Highly recommend to satisfy a craving. 

  7. I’ve been on the hunt for low calorie chocolate recipes and this really satisfied the craving. I only used 1/3 cup of honey, didn’t add the chocolate chips, & used baking powder instead of baking soda (didn’t have any). I also used the pb2 cocoa powder instead of pb powder (less calories in the cocoa version). I looove how dense they turned out. And it knocked them down to about 75 calories each ☺️

      Hi Hillary. Since you used the PB2 cocoa powder, did you still add in the separate cocoa powder from the recipe? did you just increase the amount of PB2 Cocoa Powder to account for the regular cocoa powder? Thanks!

      1. I used the pb2 with cocoa and these were perfect. I occasionally add walnuts!

  8. These weren’t too bad. They did have a slightly ‘weird’ taste, but I think that was just the honey that I wasn’t used to. I liked the texture of them. They were simple to make and baked up nicely. I was happy to find a use for my gigantic jar of powdered peanut butter other than just using it to dip celery!

  9. These are my favorite brownies!  I scale down to only 1/3 cup of honey and 1/2 cup of chocolate chips, cut them into 16, then they are only 4 green points! Nobody can tell and they are the perfect sweet afternoon snack!

  10. I’m sorry but I followed directions exactly and it doesn’t taste very good. More like cake, but too much honey taste and kinda dry. 

  11. Wondering about the raw organic honey and if this is ok to use in the recipe that will be eaten by people with potentially compromised immune systems, such as the elderly? thanks for feedback.
