I've always been an advocate for using store-bought gluten-free flour blends because of their convenience and ease of use. It saves you from having to keep numerous small bags of different gluten-free flours and starches around and it simplifies your gluten-free baking.
Cup4Cup gluten-free flour has always been a go-to of mine. It was the only flour that worked so well in many of my gluten-free recipes, like gluten-free pie crusts and homemade gluten-free pasta. It's also great for cookies, like these gluten-free peanut butter chocolate chip cookies, and quick breads, like my gluten-free banana bread. While it is one of the more expensive gluten-free blends, it was always worth it to me because it worked so well.
What Is Cup4Cup?
Cup4Cup is a commercial gluten-free flour blend that was developed by chefs at Thomas Keller's The French Laundry. It was designed to replace wheat flour in equal amounts, or cup for cup, in any recipe. It had a unique mix of cornstarch, rice flours, and milk powder, making it the go-to choice for delicate baked goods like gluten-free cakes, biscuits, and breads.
Changes to Cup4Cup Multipurpose Blend
In October 2024, Cup4Cup reformulated their multipurpose blend to remove milk powder and with that changed up the ingredient list-rice flour blend is now the first ingredient, rather than cornstarch. These changes have sparked questions and concern from many in Cup4Cup's loyal fan base.
While Cup4Cup maintains that these changes do not affect performance, many longtime users, including myself, are concerned about how these adjustments might impact our favorite recipes.
Why Consider a Homemade Blend?
Despite the benefits of pre-made mixes, there's something empowering about creating your own gluten-free flour blend. It puts you in control of your gluten-free diet, allowing you to adjust ingredients to meet your specific dietary needs and taste preferences. Homemade blends can also be more cost-effective and prevent any surprises from brand recipe changes. Taking charge of your flour mix ensures consistency in your baking and gives you a deeper understanding of your ingredients.
The success of this recipe also inspired me to create my own homemade recipe for Bob's Red Mill gluten-free flour as well!
Recipe Testing Notes
I took great care in my efforts to reverse engineer this flour blend. I wanted it to be as close to the original Cup4Cup multipurpose blend as possible. Based on the ingredient list and nutritional analysis, I think this is as close as you can get with a homemade blend to the original Cup4Cup multipurpose blend.
I've tested this flour on my pie crust, pasta dough, and biscuit recipes; it is working just as well as the original cup4cup blend. The pasta needs a bit more water though, so keep that in mind when you work with it if you're using that recipe. I plan to go in and tweak that recipe and will update here when it's done also.
For the best results and to avoid a grainy texture, use superfine rice flours. Make sure to look for labels that specifically mention 'superfine' when shopping, as this indicates they are very finely ground. This small detail is often missed and can make a huge difference in your recipes.
Update (12/23/24): I've decreased the amount of xanthan gum in the blend to about 2% because the previous 3% seemed to be too much for some recipes. If you prefer, you can always leave the xanthan gum out and add it as needed per your recipe.
Simple Ingredients

- Cornstarch: Lightens the blend, which can help mimic the texture of gluten-containing flours. It also helps in thickening and binding.
- White Rice Flour: Provides a neutral flavor and a light texture. It forms the base of many gluten-free flour blends. Use superfine white rice flour for the best results.
- Brown Rice Flour: This whole grain flour adds a slight nuttiness and more fiber compared to white rice flour, which can improve the nutritional profile and give a heartier texture. Use superfine brown rice flour for the best results.
- Tapioca Flour (Tapioca Starch): Contributes a chewy texture and helps in binding and moisture retention, making it essential for achieving the right texture in baked products like cakes and breads.
- Potato Starch: Not to be confused with potato flour, potato starch is a light, fine powder that helps add moisture to baked goods without making them heavy, which is crucial for gluten-free baking.
- Xanthan Gum: Acts as a stabilizer and emulsifier, helping to give doughs and batters more elasticity, trapping air, and thus allowing breads and cakes to rise better and hold their shape.
- Whole Milk Powder: Enhances browning, adds richness, and can also improve the structure and texture of baked goods, contributing to a tender crumb.

Top Recipe Tips!
Before using your homemade gluten-free flour blend, it's crucial to give it a good whisk. This helps redistribute the flours and starches evenly, ensuring consistency in your recipes every time you bake.
I learned from my friend Daniela over at The Gluten-Free Austrian, that if you really want to mix it up well and make sure everything if finely ground, you can give it a whiz in a high-powered blender. I tried this in the Vitamix dry grains jar for my blender and it works remarkably well! Such a great tip!

Recipe FAQs
One cup of this gluten-free Cup4Cup flour blend weighs 128 grams.
Substitutions can be made in this homemade Cup4Cup flour recipe. For instance, if you need a dairy-free version, you can omit the milk powder or replace it with a dairy-free milk powder alternative. Similarly, if you're sensitive to corn, arrowroot powder can be used in place of cornstarch. Just keep in mind that each substitution may alter the texture and behavior of the flour in your recipes, so some experimentation might be necessary to achieve your desired results.
Cup4Cup is a versatile flour for gluten-free baking. It excels in a variety of uses, from light and fluffy cakes and cookies to artisan breads and pizza dough. This flour also performs well in making smooth roux for thickening sauces, as well as tender pie crusts and pastries.

Donna says
I've made this flour recipe and used it to make my first good soft loaf of bread. After many failures using KA 1 to 1 /measure for measure, the KA only made bad crumbly hard horrible bread. I'm so thankful for this recipe. Thank you
caroline says
I am not able to get brown rice flour, could i just use more white rice flour?
Katie Olesen says
I haven't tried it but I suspect it will change the balance of the blend.
Nancy says
I really loved this brand of flour but I unfortunately have a dairy allergy as well. Can I substitute the milk powder with something else?
Katie Olesen says
The new Cup4Cup formulation is dairy free, they removed the milk powder. I haven't tried any dairy free milk powders in this blend, so I don't have substitution recommendations at this time.
Evelyn says
Can you convert the flour mixture into cups instead of grams.
Katie Olesen says
To be quite honest, it's better to measure by weight for this one. It will be more accurate, giving you better results.
Marybeth says
I’m going to give us a try! Do you think this would work well making sourdough bread using my gluten-free sourdough starter?
Katie Olesen says
I don't know how well it would perform in your sourdough recipe. Does the recipe call for Cup4Cup? Or what flour blend do you normally use?
Louise Gagne says
Can I substitute Arrowroot starch for the cornstarch as I'm deathly allergic to corn?
Thank you for your hard work putting this together.
Katie Olesen says
I haven't tried this yet. I think it could work. I will give it a try soon and report back!
Sally Meyer says
Did you try it with the arrowroot starch? I love this for most of us who are gf, but have a grandson with many allergies including corn. I’d love to make him some bread.
Julie Parnell says
This is the blend I make all the time now
Perfect 👍
Katie Olesen says
So happy you're enjoying it, Julie! Thanks for the feedback! P.S. I'm currently working on a Bob's Red Mill copycat too! 😉
Joanne says
Best I’ve made so far. Texture is much better than some of the others that I’ve tried. Thank you.
Katie Olesen says
Thanks for the wonderful feedback, Joanne!
Kathy says
Would this recipe be alright to make a loaf of bread in a bread machine , have tried but failed so far, any advice would be much appreciated 👍
Katie Olesen says
Unfortunately, I haven't made much gluten-free bread in a bread machine. I don't have any advice other than I'd look for a recipe that specifically calls for Cup4Cup.
Lorena says
What can I add to a bag of the new formula to make it like the old formula?
Katie Olesen says
According to Cup4Cup, you can add 9 grams of milk powder to one cup of Cup4Cup Multipurpose Flour to make it similar to the old blend. I haven't personally tried this yet though, so let me know what you think of it if you give it a try!
Elle says
Sadly, just adding milk powder to the new formula will not make it like the old. They changed more than just removing the milk powder.
Katie Olesen says
I tend to agree with you. Hope you enjoyed the recipe!
Eleanor says
would 1 cup = 128g ? Thank you.
Katie Olesen says
Yes! That's correct.
Dani says
Is powdered egg white a suitable substitute for the milk powder. Would it provide similar browning and protein structure?
Katie Olesen says
I haven't tried this, so I am not sure how it will behave in all recipes. If you do, let us know how it works for you.
Callista says
Can I use Meyenburg powdered goat milk?
Birdie says
I don't see why not; that's what I plan to do!
Lynne says
Thank you, Thank you, THANK YOU!!!! America’s Test Kitchen addresses the addition of milk or milk powder in recipes. Who wants an anemic-looking pastry? Cup4Cup would have been wiser to have two products. I will think twice before purchasing their flour.
Melanie Muller says
I totally AGREE with you, Lynn! For the life of me, I don't understand why Cup4Cup doesn't offer "both" blends. I mean, why not? I'm stumped as to why they didn't make that (brilliant) business decision.
Zion says
I have corn sensitivity. Can the corn starch be replaced with another starch?
