How to DIY Cake Flour and Self-Rising Flour

May 24, 2016

We're revisiting this post to remind you that you probably have everything you need to make both cake flour and self-rising flour in your pantry. Right now.

A lot of us keep a bag of all-purpose flour kicking around, a faithful old friend that we lean on for pancakes, muffins, and everything in between. More devoted bakers might even have a few wildcards in their baking arsenals, like whole wheat pastry or spelt flour. But only in the most organized and well-stocked of home pantries will you find a bag of the self-rising variety, or cake flour in its kitschy, outdated packaging.

If you didn't plan quite so far ahead, you might get tripped up on a recipe that calls for one of these vaguely esoteric flours. Don't want to make another trip to the grocery store? Never fear. Both are easily faked at home, using ingredients that you probably have on hand.

Cake Flour

Cake flour has a lower protein content (8%) than its all-purpose cousin (11%), which means your batter won't develop as much gluten and your finished product will be lighter and softer, with a finer crumb. Sometimes higher-protein flour is a good thing, like when you're baking a sturdy loaf of bread, but if you're whipping up an airy chiffon cake, your recipe might call for cake flour.

You can replicate it by measuring out the same amount of flour that your recipe calls for, replacing all-purpose flour for cake flour. Next, remove two tablespoons of flour for every cup of flour you're using, and replace each of those tablespoons with cornstarch. So, if your recipe calls for 2 cups of cake flour, measure out 2 cups of AP flour, remove 4 tablespoons, and add 4 tablespoons of corn starch. If your recipe calls for 3 1/2 cups of cake flour, you'll remove 7 tablespoons, and so on and so forth.

Whisk together your flour and cornstarch, and then sift. A lot. About five times, actually. Since we're aiming for lightness, you want your hacked cake flour to be very-well aerated, with the corn starch completely integrated. Sorry, it wasn't my idea—Alice said you have to.

Self-Rising Flour from Food52

And voilà, cake flour!

Self-Rising Flour

This variety already has salt and baking powder mixed into it, so recipes that call for it typically won't require additional salt or leavening. It's a very big deal in Southern cooking, especially in biscuits, and it's also pretty simple to replicate: for every cup of self-rising flour that your recipe calls for, measure out one cup of all-purpose flour and add 1/4 teaspoon salt and 1 1/4 teaspoons baking powder.

So, if your recipe calls for 2 cups of self-rising flour, you'll measure out 2 cups of all-purpose flour, and add 1/2 teaspoon salt and 2 1/2 teaspoons baking powder.

Whisk everything together, and then sift. That's right, about five times total. Aeration, you know. Alice's orders.

Keep in mind, however, that certain cult-following brands of self-rising flour such as White Lily and Presto are similar to cake flour in that they're milled from softer wheat and have a lower protein content than all-purpose. If your recipe calls for one of these flours, or you feel like being a total over-acheiver (unlikely, since this particular kitchen hack is an exercise in laziness), use your DIY cake flour instead of all-purpose in the above conversion. Your unthinkably fluffy, mile-high biscuits will thank you.

I have a recipe that calls for cake flour. I only have self
rising flour. Do I need to make any changes?
Betty D. February 14, 2018
Yes. Cake flour has cornstarch added. You need 2 tablespoons for every 1 cup of flour. Remove 2 tablespoons of flour and add 2 tablespoons of cornstarch. Then sift it well.

Hi there. If the recipe calls for 350 g of self raising flour thays abt 2 3/4 cups i think? How many salt and baking powder should i place and should i leave out thr 3tsp baking powder thats included in the ingredients? Or keep it?

What if the flour is in weight in the recipe? Other than converting flour in weight to flour in cups, do you have a formula for these DIYs when flour is measured in weight? thank you.

Read this before using in an angel food cake the DIY alternative suggested above: Scroll down to the third set of comparison cakes for more information on this substitution, as well as compelling evidence proving the point. ;o)

Could I use rice flour or potato flour in place of reg. flour?

To turn all purpose into bread flour, I keep Hodgson Mill Vital Wheat Gluten on hand.

I myself use a different formula for cake and self rising flour that always deliver superior results. 1 cup cake flour = 3/4 cup all purpose + 2 tbsp cornstarch. 1 cup self rising flour = 1 cup all purpose flour + 11/2 tsp baking powder. I omit the salt but if I must I put only 1/8 tsp. I bake all the time and these formulas always work for me. Also, I don't like cake flour due its acidific aftertaste and what I think is a powdery texture, and i have made cakes that ask for cake flour and then made then a second time using my formula. The cakes made with the combination of AP flour and cornstarch is superior in terms of texture and taste.

Looking forward to trying your version--thanks Regine!

What about pastry flour? I use to have a local source for it, but no longer. Someone told me that pastry flour was similar to cake flour. Can anyone clear that up for me?

Pastry flour is similar, but not identical, to cake flour -- it's also low-protein, but the protein level usually sits somewhere between those of cake flour (8%) and all-purpose flour (11%), and it's slightly starchier. If you're in a pinch, using a 50/50 mix of cake flour and all-purpose flour makes a good pastry flour substitute.

Thanks Jen!

Can someone make a large batch of something like this and keep it in the pantry? Kinda like keeping a bag of the premade stuff?

Wow, this is great I can't wait to try it out and of course take photos.

Very helpful, even for this old-school type who cannot imagine a pantry without cake flour (but finds herself without enough on occasion, and appreciates being spared a trip to the grocery). Quick question, though . . . . does the cake flour conversion work when measuring by weight, not volume? Yes, I know that most recipes in the US are by volume, but being lazy to the core, I much prefer using a scale; typically I convert based on the nutrition information on the box. (Those labels with the calories, fat content, etc., always include both volume and grams; simple arithmetic is all one needs to make the conversion.) Thank you! ;o)

Ooh, that's a good question. I imagine the conversion would work just fine, as long as you keep the proportions the same, but perhaps more seasoned bakers could chime in?

I am always surprised at some of the cultural cooking differences between countries, in the UK every shop that sells flour will have at least two varieties (and often more) - plain and self-raising

Thanks for the translation. From what I gather from a couple of baking books published in the UK, self rising flour is more frequently used there as well.

Great tip on the self rising flour. I remember looking in the past and not being able to find the amount of baking powder to flour ratio!
