Recipe Ingredient Notes
Gluten Free Flour: I use my own Gluten Free Flour Blend in this recipe. This blend already contains xanthan gum. If you would like to use Bob's Red Mill 1-1 or King Arthur Measure for Measure Flour please reduce the flour to 150 grams.
Brown Butter: The browned butter gives the Gluten-Free Peanut Blondies a hint of nuttiness and keeps them soft and chewy. Brown Butter is made by slowly cooking butter over low heat. The butter turns golden brown with a nutty aroma, and the milk solids separate into brown specks that sink to the bottom. Brown butter smells like toasted hazelnuts. If you have never made brown butter before, make sure to check out my step-by-step instructions found here: How to make Brown Butter
Peanut Butter: I use Jif Creamy Peanut Butter in this recipe. All-Natural Peanut Butter will NOT work and result in a very dry blondie. Save that organic all-natural PB for snack time.
Chocolate: In this recipe, I use a mix of dark chocolate chunks and a chopped-up milk chocolate bar. This is a great recipe to use up odd ends of chocolate chips and chunks you may have in your pantry. I like having big puddles of chocolate on top of my blondies so I do top the blondies with additional chocolate before baking.
Peanut Butter Cups: I use Reese's Peanut Butter cups in this recipe. All varieties of Reese’s Peanut Butter Cups are gluten-free except for their seasonal items. Please make sure you double-check the packaging before purchasing.
Peanut Free Alternatives: I have not tested this recipe with an alternative to Peanut Butter. But there should be no issue substituting a different kind of nut or seed butter for the peanut butter. As for the Peanut Butter Cups, there are several options available on the market these days such as Almond Butter Cups and Sunflower Butter Cups. You can always substitute the peanut butter cups for additional chocolate.
What is the difference between a blondie and brownie?
Blondie recipes are similar to brownies. They are made with brown sugar, melted butter, and vanilla which gives them their distinctive butterscotch flavor. Their consistency is very similar to brownies. They are rich, dense with a fudgy texture from the melted butter.
Just like brownies, blondies can be made with a variety of add-ins such as dried fruit, chopped nuts, chocolate, and of course candy.
How to make Gluten Free Peanut Blondies
This recipe for gluten free peanut blondies can be made by hand with a whisk, hand mixer, or your stand mixer.
- Preheat your oven to 350F
- Line an 8×8 pan with parchment paper and set it aside. Make sure to leave some overhang so you can easily remove your blondies from the pan.
- In a small pot, over medium heat, melt your butter. Continue cooking and stirring until the butter starts to smell nutty and turns a medium amber color. Remove from the heat and transfer into the bowl (make sure to get all the brown bits) of your mixing bowl and allow to cool for 10 minutes before proceeding with the recipe.
- In the meantime combine your gluten free flour, milk powder (if using), baking powder, and salt and whisk to combine.
- Once your browned butter has cooled, add the peanut butter and sugar to it and whisk to combine.
- Add the room temperature egg and vanilla and mix well.
- Mix in your dry ingredients. This is is easier with a flexible spatula than a whisk.
- Fold in your chocolate chips and chopped up peanut butter cups (or other add-ins you may want to use instead)
- Add the batter to the prepared pan, smoothing out the top with the back of a spoon or an offset knife.
- Top the peanut butter blondie batter with additional chocolate and peanut butter cups. Bake at 350F for 24-26 minutes. 24 minutes will give you a fudgier blondie while 26 minutes (or longer) will give you an almost fully baked blondie. Baking times depend on your oven.
- Remove the gluten free peanut blondies from your oven, sprinkle with some flaky sea salt (if using) and allow for them to cool in the pan.
- Store any leftover blondies you may have in an airtight container at room temperature up to 5 days.

Baking in grams
I share my recipes in grams and by weight since baking by weight is the most accurate way to bake. Digital Scales are very affordable and very affordable. You can purchase them on Amazon for less than a set of measuring cups. Measuring cups are very inaccurate and can cause significant errors when it comes to baking. Especially since I bake with gluten-free flours which weigh differently than “regular” flours. I do provide some ingredients like spices and leavening agents in measuring spoons. To learn more about Baking with a digital scale, make sure to check out my post about Baking by weight.
Note about Ovens and Oven Temperatures
All my recipes are tested and developed with a conventional oven. I always bake my baked goods on the rack placed in the MIDDLE of my oven. This way the heat coming from the bottom will not burn my baked goods.
If you are baking with convection (fan-forced), please adjust the recipes accordingly. Be also prepared that the convection oven can cause your baked goods to dry out quickly and still be raw inside. Be aware that it takes at least 15-20 minutes for a standard American Oven to be fully preheated. I highly recommend investing in an Oven Thermometer.
Substitutions and Modifications
Any dietary or ingredient modifications/substitutions to this recipe may alter the end result in appearance and taste. I test my recipes several times as published in this post and The Gluten Free Austrian Blog is not responsible for the outcome of any recipe you find on our website.
