For those new to or experienced in allergen-friendly cooking, understanding which King Arthur flour is gluten-free is an essential first step for successful baking.

Quick Summary

King Arthur offers specific gluten-free flours for different baking needs: Measure for Measure for 1:1 substitutions in non-yeasted recipes, and an All-Purpose blend for scratch recipes calling for a GF mix. Additional specialized GF options are also available.

Key Points

Choose Correctly: Not all King Arthur flours are gluten-free; select a product from their certified gluten-free line.
1:1 Conversion: Use King Arthur's Gluten-Free Measure for Measure Flour for an easy, cup-for-cup swap in most non-yeasted recipes.
For Scratch Baking: Use King Arthur's Gluten-Free All-Purpose Flour when a recipe calls for a specific GF blend, often requiring the addition of a binder like xanthan gum.
Different Flours, Different Uses: The two main gluten-free blends are for different purposes; Measure for Measure is best for quick breads and pastries, while the All-Purpose is better for yeasted items with specific liquid adjustments.
Trust the Certification: All of King Arthur's gluten-free flours are Certified Gluten-Free by the GFCO, ensuring they meet rigorous standards.
Adjust Your Baking: Be prepared for slight differences in texture and baking time with gluten-free flour blends and let baked goods rest for the best results.

King Arthur's Dedicated Gluten-Free Products

While King Arthur offers a wide range of flours, not all are gluten-free. The company provides a specific line of products dedicated to gluten-free baking, and it's essential to check the label for certification. The two primary offerings for general baking purposes are the Measure for Measure Flour and the Gluten-Free All-Purpose Flour, each formulated for different uses.

King Arthur Gluten-Free Measure for Measure Flour

This blend is designed to be a direct, 1:1 substitute for traditional all-purpose wheat flour in most non-yeasted recipes. It is a convenient option for bakers who want to convert a traditional recipe without overhauling the ingredient list. The formula is crafted to mimic the structure and texture of conventional flour, making it ideal for the following baked goods:

Cookies
Cakes
Muffins
Brownies
Pancakes

Unlike the All-Purpose version, this blend contains xanthan gum, which acts as a binder to replace the elasticity and structure that gluten provides. This means you typically do not need to add any additional binders when using this flour.

King Arthur Gluten-Free All-Purpose Flour

This blend is intended for bakers using recipes that specifically call for a 'gluten-free flour blend'. It is formulated without xanthan gum, which allows for greater control over the final texture, especially in yeast-based recipes where an elastic structure is desired. The blend consists of:

White rice flour
Whole grain brown rice flour
Tapioca starch
Potato starch

Since it does not contain xanthan gum, you will need to add a binding agent, such as xanthan gum or psyllium husk, to your recipes when using this blend. This gives experienced gluten-free bakers more flexibility to tailor their bakes.

Other Specialized King Arthur Gluten-Free Products

Beyond the primary blends, King Arthur also offers specialized mixes and flours for specific gluten-free recipes, including:

Gluten-Free Bread Flour: Specifically formulated for yeasted breads, with added sorghum flour and xanthan gum.
Gluten-Free Pancake Mix: A ready-to-use mix for quick and easy gluten-free pancakes.
Gluten-Free Brownie Mix: A popular and easy-to-use mix for fudgy brownies.

Pro Tips for Baking with King Arthur Gluten-Free Flours

Achieving perfect results with gluten-free flour can sometimes require minor adjustments. Follow these tips for a better baking experience:

Rest the Dough: For cookies, consider refrigerating the dough overnight. This allows the flours to fully hydrate, reducing grittiness.
Adjust Liquid: For yeast recipes using the Gluten-Free Bread Flour, you may need to add a couple more tablespoons of liquid per cup of flour, as the blend is more absorbent than wheat flour.
Expect Different Textures: Understand that gluten-free bakes will have a different texture than their conventional counterparts. Often, they can feel a little wetter when they come out of the oven but will firm up as they cool.
Check for Doneness Differently: The 'toothpick test' might not be reliable. Instead, rely on a deep golden-brown color for visual cues of doneness.
Don't Over-Knead: Gluten-free doughs do not need to be kneaded with the same intensity as wheat-based doughs. Gentle handling is key to prevent a gummy texture.
