Flourless Peanut Butter Blondies (2024)

This Peanut Butter Blondie recipe is as easy as it gets, calling for only 6 ingredients that you probably already have on hand. They are unbelievably decadent, while being naturally-sweetened and flourless!

What’s the Difference Between a Brownie and a Blondie?

If you’re not familiar with “blondies,” they are basically brownies without cocoa powder added in. They remind me of a deep dish cookie, with more of a buttery, brown sugar flavor. And they’re even more like a deep dish cookie when you add in some chocolate chips!

How to Make Gluten-Free Blondies

These peanut butter blondies are naturally gluten-free because they use NO flour– and you don’t even miss it! They are inspired by the book Breaking the Vicious Cycle, which lays out guidelines for the Specific Carbohydrate Diet (also called SCD, for short).

This special diet may help to heal the intestine (including yeast overgrowth, like candida) through avoiding certain types of starches and sugars, while embracing others. Honey is one of the recommended sweeteners for the SCD, as it’s a monosaccharide, and can be used by the body very quickly without expending much digestive energy.

I’ve also included a vegan option using coconut sugar if you prefer to use that. (You can find my substitution notes directly under the printable recipe in this post.)

How to Make Them

Making these flourless peanut butter blondies couldn’t be easier. Simply stir together the peanut butter, honey, egg, salt, and baking soda, and pour it into a pan to bake.

Just 20 minutes later, it’s like a rich deep-dish cookie!

I like to add some dark chocolate chips to these for extra decadence, but that’s totally optional. (And chocolate is not SCD compliant if you follow that protocol.)

It’s important that you let these blondies cool completely before slicing and serving them. They are very tender when they are warm, and will be difficult to hold without them breaking.

I recommend placing them in the fridge to cool down faster, and I even keep mine stored in the fridge because they last longer that way.

Which Peanut Butter is Best for Blondies?

I use all-natural peanut butter when making this recipe, which has no added oil or sugar. (You can make homemade peanut butter in just 5 minutes, too!)

If you want to use a peanut butter like Jif or Skippy, that will most likely work, too, but I haven’t tested those myself. (But let me know if you try it so I can hear how it goes for you!)

How to Make Vegan Blondies:

To make this recipe vegan, replace the egg with a chia egg, and replace the honey with 1/2 cup of coconut sugar. Check out my Almond Butter Blondies, which are naturally vegan & paleo friendly for this method.

As always, feel free to experiment with other nut butters and sweeteners. If you try something different, please leave a comment below letting me know what worked for you! We can all benefit from your experience.
