Peanut Butter Chocolate Chunk Blondies (Gluten Free, Refined Sugar Free)
Rich, fudgy, and studded with puddles of melted dark chocolate, these Peanut Butter Chocolate Chunk Blondies are made with simple, gluten-free ingredients you probably already have on hand. They’re the perfect treat to bake when you’re craving something a little sweet and salty.
These blondies are everything I love in a peanut butter dessert.
Thick. Gooey. Packed with chocolate. They come together in just one bowl with ingredients I always have on hand. I used chopped dark chocolate instead of chips for extract big and perfect melty puddles.
These blondies are naturally gluten-free, and refined sugar-free, but you’d never guess it from how good they taste. I’ve made them for friends who had no idea they were “healthier,” and they vanished in minutes.
I love storing them in the fridge for that extra fudgy texture, but they’re also amazing warm from the oven with a scoop of vanilla ice cream. You truly can’t go wrong with these.

Why You’ll Love These
One-bowl recipe: You don’t even need a mixer, just one bowl and a spoon.
Deeply satisfying texture: Soft, gooey, and slightly chewy with crisp edges and a molten center.
Naturally gluten-free: Made with just a little gluten-free flour and peanut butter as the base.
Sweetened with coconut sugar + maple: Lower glycemic and less processed than white sugar.
Chocolate in every bite: Chopped dark chocolate gives these the best texture and melty center.
What You’ll Need
Creamy peanut butter: Acts as the main fat and structure. Choose a drippy natural kind that only contains peanuts and salt.
Eggs: Help bind everything and create that rich, fudgy center.
Maple syrup: Adds moisture and natural sweetness.
Coconut sugar: Gives a deep caramel-y sweetness and enhances chewiness.
Gluten-free flour: I used a 1:1 blend, but oat flour could work too.
Baking soda: Just enough to give them a little lift.
Chopped dark chocolate: Way better than chips! Those gooey pools are everything.
Vanilla extract: Rounds out the flavor perfectly.
Flaky sea salt: The perfect finish for that sweet and salty flavor.
How To Make Them
Preheat the oven to 350°F and line an 8×8 pan with parchment.
In a large bowl, stir together the peanut butter, eggs, maple syrup, coconut sugar, and vanilla until smooth.
Add the gluten-free flour and baking soda, and stir until just combined.
Fold in the chopped chocolate, reserving a few chunks for the top.
Spread the batter evenly into the prepared pan and top with remaining chocolate.
Bake for 20–25 minutes, or until edges are golden and center is just set.
Let cool before slicing for clean edges (or dig in warm…no judgment here).

FAQ
Can I use a different nut butter?
Yes! Almond butter or cashew butter will work well. Use a thick, natural nut butter for best results.
Are these blondies refined sugar-free?
They’re sweetened with maple syrup and coconut sugar, both are unrefined, lower GI alternatives to white sugar.
Can I make these vegan?
You can try flax eggs (1 Tbsp ground flax + 2 Tbsp water) just know the texture may be softer.
Do they need to be refrigerated?
Once cooled, store in an airtight container at room temp for 2 days or refrigerate for up to 5 days. They also freeze super well!
