So what are blondies, and what do they taste like? To put it simply, they have the soft, chewy texture of a brownie with the irresistibly rich vanilla flavor of a chocolate chip cookie, despite the higher fat to flour ratio. However, blondies are way easier to make than either brownies or chocolate chip cookies, the perfect sweet tooth fix for a busy schedule.

Why You'll Love This Recipe

  • Gluten free blondie bars are great for kids. Actually, I figure that most anyone would have a hard time passing up these yummy cookie bars!
  • They're quick & easy. You mix up the dough, dump it in a pan, and bake in the oven; that's it!
  • Blondie bars are baked like a brownie, but they take on the vanilla flavor of a chocolate chip cookie, the best of both worlds!
  • They're irresistibly rich and chewy with a crisp, sweet top, and they're full of melt-in-your-mouth white chocolate chips.

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

Although blondies have the soft chewiness of most brownies, there are some starkly contrasting differences between the two.

Unlike brownies, blondies have no cocoa powder or melted chocolate. So the dominant flavor in blondies comes from the brown sugar, not chocolate.

The lack of cocoa is also responsible for their signature blonde color.

What's the Difference Between a Blondie and a Brookie?

Brookies are made by alternating layers of brownie batter and chocolate chip cookie dough in a baking pan. The result is a rich, fudgy cookie bar that is half chocolate chip cookie and half brownie.

On the other hand, blondies are made of their own unique dough that resembles features from both brownies and chocolate chip cookies. Although they share many similarities and are equally delicious, blondies and brookies are not the same.

Ingredient Notes

Let's talk about a few of the ingredients for this gluten-free blondie recipe…

  • Vegan Butter – I use dairy free plant butter, like Earth Balance sticks. Other dairy free substitutes might include vegetable oil, canola oil, coconut oil, applesauce, and even some mayonnaise! Of course, if you don't care to make this recipe dairy free, you can simply substitute 1:1 with regular salted butter.
  • Brown Sugar – For this recipe, I use a mix of light brown sugar and dark brown sugar. The darker the brown sugar, the more molasses it contains. It's crucial that you use the exact amounts specified, as the type of brown sugar used can greatly affect the final flavor and texture of the bars.
  • Vanilla Extract – I always avoid imitation vanilla, instead opting for 100% real vanilla extract. In my opinion, real vanilla is far superior in flavor.
  • Gluten-Free All-Purpose Flour – I almost always use Authentic Foods Classical Blend gluten-free flour. Time and time again, this flour blend has given me the best results and gluten-free baked goods that taste no different than the original.
  • Xanthan Gum – I add xanthan gum to my flour to help give the blondie bars a leavening agent. Some flours already contain xanthan gum, so be sure to check the ingredients before adding more. Too much xanthan gum and/or baking powder can give the blondies a soapy flavor.
  • Dairy-Free White Chocolate Chips – Being a dairy free recipe, it is important that you use dairy free white chocolate chips.

Expert Tips and Recipe FAQ's

Why are my blondies too cakey?

Although cakey blondies can be a result of either too much liquid in the batter or under-stirring, the most common cause is over-baking. To obtain that soft, chewy texture that blondies are so well-known for, it's important that you bake them only to the point that a toothpick inserted into the center comes out mostly clean, but with a few moist crumbs. If there are no crumbs on the toothpick, your blondies are over-baked.

Why did my blondies sink?

Most of the time blondies will sink when they are too raw in the middle. This can be either a result of undercooking or, more commonly, it can also happen when the eggs and sugars are not mixed together well enough. In fact, under-aeration of the blondie batter will result in a doughy, greasy mess. For more information, check out this great article on, “Why Your Blondies Are Raw In the Middle” over at Food52.

Are blondies supposed to be gooey?

Although they shouldn't be overly greasy, it's normal for blondies to be slightly gooey in the middle. If you prefer a more cake-like blondie, bake them longer, or 'til a toothpick inserted into the center comes out clean with no crumbs.

How do you store them?

Stored in an airtight container at room temperature, gluten free dairy free blondies will typically last for up to 5 days.

Can you freeze gluten-free blondies?

Yes, you can. The best way to freeze blondies is by wrapping them in either plastic wrap or aluminum foil and placing them in an airtight container or freezer bag in the deep freeze. Stored this way, they should last up to 3 months. To defrost, simply leave them on the counter at room temperature for a few hours.

What Can I Add to Blondies?
