Ask Judy – Canola oil and Baking

Converting a recipe from butter to canola oil

Last month one of our readers asked: “How does one convert a recipe that uses butter, to one that uses canola oil?”

Thanks, Jeanine from for the great question.  We are glad you asked and Judy is happy to answer.

The following post is brought to us by guest blogger Judy Fowler, Recipe Developer, Tester and Food Stylist. 

Q: How does one convert a recipe that uses butter, to one that uses canola oil?

A: We are very happy to report that – yes – this substitution is actually fairly straightforward. Generally, when substituting canola oil for butter in baked products, you can use ¾ cup of canola oil for every cup of butter.

If you do a straight conversion (cup for cup), you will need to slightly reduce one of the other liquid ingredients in the recipe. You want to retain the consistency of your dough or batter.

You should not notice any difference in consistency in quick bread batters or doughs or yeast bread doughs. You might find a slight difference in the consistency of some cookie doughs.

Once you start using canola oil in some of your breads and cookies, you should find that, overall, very little needs to be changed. I think you will be quite surprised at the results in some of your baked products when you make this substitution.

We have had great comments about the chocolate chip cookie recipe in our recipe bank. I would suggest that you try this recipe and “get the feel” of baking with canola oil!

  1. Wonderful! Thank you very much for taking the time to answer my question – perfectly timed for the “My Cookies are the Best” contest too. 😉
    I appreciate it!


  2. Thanks for answering Jeanines question as it helps me as well as I am lactose intolerant . .how do I get a “creamy” soup without the dairy, Judy?

  3. My question is, can I reverse the above chart? As in, if the recipe calls for canola oil, how do I determine the best substitute? How much butter, or corn oil, or olive oil, to use instead? (Canola oil makes me ill – if someone is cooking with it and heats it, the smell makes me retch, and if I consume it in any form – in a recipe or an item cooked in it – I get stomach cramps and other ill feelings).

    1. Hi Anne,
      Thank you for your question. It is not our area of expertise to convert recipes from oil to a solid fat. Perhaps our friends at Dairy Farmers of Manitoba would have an answer for you. Their website is

    1. Thanks for you comment! It would depend on the type of recipe. If you are making a standard batch of muffins, cookies or a cake I would start with 1/2 cup and adjust from there. All the best with your baking!

  6. Hi!

    I have been toying with recipes for cupcakes and I’ve seen canola oil come up in some ingredient lists. What can canola oil do to make a cupcake better?

  9. I’ve been using canola oil instead of butter in recipes for years. It is especially good for cookies. I have been using an equal amount of oil for butter but will try reducing the oil as suggested here. Nobody has ever complained about the lack of butter in my baked goods. Cookies and cakes disappear like magic.

    1. Canola oil can be used to bake cookies. Have you tried out Judy’s Chocolate Chip Cookie recipe? It’s one of our favourites.

  11. Hi Judy,

    This information will be very useful because I have a dairy allergy. When I bake cakes for myself I have to use Canola Margarine or any other vegetable oil.
