This gluten-free blondies recipe is made with gluten-free flour, brown sugar, butter, and vanilla. Simply make the batter, spread it into a pan, and bake. And since it’s so easy to make, it’s a great recipe for beginner gluten-free bakers.
Gluten-free blondies are dense, buttery, and very rich. Once you make a pan, you’ll understand why they’re a beloved baked good.
Most folks think of blondies as a “vanilla brownie” or a blond brownie. Since it’s impossible for me to think about brownies without chocolate, that definition never worked for me. Instead, I think of them as a cross between a chocolate chip cookie bar and brown sugar fudge.
If you want something a little less rich and buttery, try gluten-free chocolate chip bars. The flavors are similar but the texture is more cake-like.
Gluten-Free Blondies: Ingredients and Substitutions.
- Gluten-Free Flour. The soft and delicate texture for these bars comes from a gluten-free flour blend. I tested the recipe with Bob’s Red Mill’s 1:1 Gluten-Free Baking flour. It contains xanthan gum. If your flour blend doesn’t add ¼ teaspoon.
- Brown Sugar. The terrific butterscotch flavor comes from brown sugar. For a caramel-like flavor, use light brown sugar. For pronounced molasses flour, use dark brown sugar.(Blondies pictured were made with light brown sugar.)
- Butter. Melted butter ensures the blondes stay thick and dense. It also adds a lot of flavor. If you’re dairy-free, use dairy-free butter. Shortening or oil don’t work in this recipe because they don’t add flavor to the bars.
- Eggs. Provide structure, richness, and flavor. Use large eggs for the best results.
- Vanilla Extract. Three things make blondies taste like blondies: brown sugar, butter, and vanilla. While you can omit vanilla extract in many baking recipes, I suggest including it in these blondies for the best flavor.
- Baking Powder. A teaspoon of baking powder gives the bars a little lift without making them too cakey.
- Salt. Since blondies are sweet, salt helps balance the flavor. For the batter, use table (fine) salt. If you want to sprinkle salt over the top, use Kosher or a flaky-style salt.
- Nuts. (optional) Some folks wouldn’t dream of making blondies without nuts. And some folks wouldn’t dream of including them. I’ll leave it up to you! Add up to one cup of toasted, chopped pecans or walnuts.
- Chocolate Chips. (optional) Add up to one cup of dark, milk, or white chocolate chips. If you want to use butterscotch chips, those are also great in blondies. As always make sure any baking chip you use is gluten-free.
How to Make Perfect Gluten-Free Blondies. Five Tips for Success.
- Whisk the gluten-free flour with the baking powder and salt. I know you might want to skip this step. But don’t. Doing this mixes the small amount of baking powder and salt throughout the flour.
- Mix the melted butter with the brown sugar, eggs, and vanilla. You’ll love this step. When you mix these ingredients together, it looks (and smells!) like caramel sauce.
- Make the Batter. This batter comes together easily. You can mix it with a rubber spatula or electric mixer. Whichever you prefer!
- Pick your pan! If you like your gluten-free blondies thin, use a 9×13-inch pan. For thicker blondies, bake the bars in an 8×8-inch pan.
- Cool the bars in the pan. In most of my recipes, I recommend moving gluten-free baked goods from the pan to a wire rack. This lets steam escape and prevents gluten-free treats from getting gummy in the center. These bars are an exception. Let them cool right in the pan.
How to Store and Freeze.
Gluten-free blondies keep at room temperature for about three days. To store them, let them cool. Then place them in an airtight container or place them on a plate and cover with plastic wrap.
To freeze them, bake as directed. Let the blondies cool and cut into squares. Place them into a freezer container. If you need to layer the bars, place a piece of waxed paper or parchment paper between the layers. Freeze for up to two months. Thaw the blondies at room temperature.

- 1 ½cups gluten-free flour, Bob's Red Mill 1:1 Gluten-free Baking Flour recommended.(7½ ounces; 212 grams)
- 1teaspoonbaking powder
- ½teaspoonsalt
- 1 ½sticks butter, melted(6 ounces; 170 grams)
- 1 ¼cups packed dark brown sugar(9 ounces; 255 grams)
- 2largeeggs
- 1teaspoonvanilla extract
- 1cupchocolate chips, optional (dark, milk, or white)(6 ounces; 170 grams)
- 1cuptoasted pecans or walnuts, chopped(3½ ounces; 100 grams)
Instructions
Preheat oven to 350°F. For thick blondies, use an 8×8-inch square pan. For thin blondies, use a 9×13-inch pan.
Line the with parchment paper, leaving a 1-inch overhang on two opposite sides of the pan.
Whisk together gluten-free flour, baking powder, and salt in a small bowl.
In a medium bowl, stir together brown sugar and melted butter until smooth. Add eggs and vanilla. Whisk until creamy.
Add gluten-free flour mixture. Mix with a wooden spoon until the batter is thick and smooth. If using chocolate chips and/or nuts, stir them in now.
Spread batter into prepared pan. If using a 9×13-inch pan, it might look like there's not enough batter for the pan. Use a small spatula or the back of a spoon to evenly spread the batter into the pan.
Bake until bars are golden brown and the top is shiny and slightly cracked. About 35 minutes for an 8-inch pan and 30 minutes for a 9×13-inch pan.

Lift bars out of the pan with the overhanging parchment paper. Place bars on a cutting board and cut into squares with a sharp knife. When cut, the bars might look underbaked. That's normal. They are very moist and buttery.
Store in an airtight container at room temperature for up to four days. Freeze cooled bars in a freezer container for up to two months. If you need to stack the bars, place a piece of parchmene paper or waxed paper between the layers.
Recipe Notes
Gluten-free flour. Use a gluten-free flour blend that contains xanthan gum. If yours doesn’t whisk ¼ teaspoon into the flour along with the baking powder and salt.
Butter.Allow the melted butter to cool slightly before adding it to the brown sugar. For dairy-free bars, use a dairy-free butter.
Nuts. Toast nuts on a baking sheet in a 350°F oven for about 10 minutes. Remove nuts from the oven when they are golden brown and aromatic. Allow nuts to cool before chopping.

Is this baking soda or baking powder? The ingredients list calls for powder, but the directions call for soda.

What do you mean by “regular” GF flour? Are you using a blend like King Arthur??

Hi Robert,
My comment about “regular” gluten-free flour was in response to a question about self-rising or plain gluten-free flour. I tested the recipe with Bob’s Red Mill 1:1 Gluten-Free Baking flour. Using a different gluten-free flour blend, like King Arthur’s, should work in this recipe but the texture of the blondies might be a little different. Hope this helps!Reply
Jules says
I made these with King Arthur’s GF Measure for Measure Flour and they were delicious. Moist, chewy, cakey texture – what’s not to like!Reply
Celeste says
The whole family enjoyed them. I did not have brown sugar but used 3/4 cane sugar and 1/3 cup maple syrup. Added some chick chips to half of it for those who can eat chocolate. All had seconds:)
ThanksReply

Thanks for this recipe. I made with King Arthur GF flour. They were “softer” than those I’ve made in the past with regular flour; not as dense or chewy. I wonder if banging the pan partway through would solve that issue. Anyway, cooking from what I had on hand, I used light brown sugar, browned the butter, added toasted unsweetened coconut flakes. chopped cashews, and Maldon salt on top. Pretty tasty!

This recipe works well with Better Batter’s all purpose gluten-free flour (cup for cup). Thank you!Reply

At 4,000 ft. above sea level, this took 55 minutes to bake! Patience prevailed, and it was DELICIOUS! The lady who wrote this knew what she was talking about, and she achieved gluten-free blondie excellence!

Love this recipe, no one would guess it’s GF! My only issue is the baking time. I always feel like mine are underdone even when I add cook time. Are they supposed to be quite gooey? I just don’t want to make anyone sick!Reply

Can u freeze these?

Yes. Let them cool first and then wrap. They keep for about two months.

What a great recipe! These taste delicious and have a wonderful texture. I wanted to make a 13×9 pan, but didn’t want them to be too thin. I made 1 1/2 the recipe and it resulted in a perfectly thick 13×9 pan of sweet, buttery goodness!Reply
Barbara says
Tried making them this morning. Rather disappointing. Color darker than photo. They stuck to pan even with parchment, fell apart when I tried to remove them. Taste good but mostly crumbs. ?
Only difference was I used Bobs Red Mill gf 1 for 1 flour.Reply
Elizabeth says
This is an odd result. The recipe was created with Bob’s 1:1 Gluten-Free Flour, which it sounds like you used? It’s hard to get anything to stick to parchment paper. But you’re saying that they stuck and then crumbled? (Just trying to troubleshoot.)
I’m not sure what would have caused them to stick. As for crumbling, I have two guesses. Something might have been mismeasured or your oven temp might be off.

Followed the recipe exactly except 1 cup sugar instead of 1.25. Quite tasty but it came out as cake not gooey blondies. Next time I will cut the flour down quite a bit bc I prefer the gooey kind and see if it works

Reducing the sugar would have changed the texture a bit to cakey. Glad you liked the flavor!
