Fat substitutes in gluten-free baking: Chocolate Chip Cookie Smackdown

One of the most common questions we get from our gluten-free readers and bakers is how to make fat substitutes in gluten-free baking. Most of our recipes use either butter or vegetable oil as the primary fat, simply because they’re the most accessible for the majority of our audience. But we also want you to know that we hear your questions about using alternatives.

Most people are unsure when you can substitute different fats 1:1 for one another: what the difference would be if you used butter vs. shortening vs. oil, for example. So we decided to put one of our tried-and-true gluten-free recipes to the test: Gluten-Free Chocolate Chip Cookies.

 

Why we chose cookies

We decided to do a cookie test for a few reasons. First, cookies generally use just one fat and don’t require any fancy techniques. Second, our Gluten-Free Chocolate Chip Cookies recipe uses butter, and many of our readers are looking for a dairy-free alternative.

Finally, that recipe is one of the most beloved on our site, with nearly 100 reviews and a 4.5 star rating. So we wanted to test versions of this cookie using alternate fats in order to enable even more people to enjoy them.

 

What fat substitutes we’re using

We had a hard time choosing which fat substitutes to try in this test, but what it boiled down to was the oils/fats that we get the most questions about from our readers baking gluten-free. Here’s what we decided on:

Butter: This is the fat used in our chocolate chip cookie recipe, and the standard that we tested against.

 

Vegan butter: This is a vegetable-based butter substitute that looks and tastes very similar to butter. It’s solid at room temperature and is usually made from a blend of plant-based oils like palm, soy, and olive. Note: We used Earth Balance Vegan Buttery Sticks, a blend of palm, soy, flax, and olive oils.

 

Coconut oil: Another non-dairy based fat, coconut oil is a bit different than vegan butter. Usually coconut oil is liquid at room temperature, but solidifies and gets rock hard when kept in the refrigerator. Note: coconut oil comes in both refined and “virgin,” which have different flavors. We recommend that you taste several before finding one with the flavor you like.

 

The fat substitute test

To make this test as fair and straightforward as possible, we kept the recipe exactly the same throughout, simply changing the type of fat. We followed the existing recipe, using our gluten-free flour, but didn’t include any nuts. The baking temperature was 350ºF.

Curious to see what happened? Here are the results.

The results

As expected, and as you can see from the picture above, the fats that we used certainly had an effect on the final recipe. We’ll talk about each of the specific fat substitutes in a moment, but we just wanted to demonstrate how much the type of fat you use in a recipe can affect the final product. These three cookies varied in everything from texture to bake time to flavor.

Butter

Out of all the versions, this was the cookie that we kept coming back to. It had the right texture, the right flavor, and was baked to perfection, with lightly browned edges and soft, gooey centers. The cookies were a wonderful blend of chewy and crunchy, and carried just the right amount of sweetness.

Since the butter was at room temperature we were able to easily beat it with the sugar, which helped make the cookies nice and light.

Dough: The dough was sticky, but was easily shaped with a cookie scoop. The cookies also kept their shape on the baking sheet.

Texture: Chewy, soft, and lightly crisp around the edges.

Bake time: 11 minutes.

Vegan butter

Our next favorite result came with vegan butter. The flavor of the cookies most resembled the original recipe, though we did notice they tasted a bit sweeter. While vegan butter doesn’t list any sugar/sweetener in its nutritional panel, we think it simply pulls out a slightly different flavor from the sugars.

Since vegan butter was also soft at room temperature, we were able to easily beat the fat and sugar together. Again, this helped keep the cookies light.

Dough: The dough in this version was a little softer than the original. When scooped onto the baking sheet, the cookies didn’t hold their shape as well, starting to spread as soon as they were scooped.

Texture: These were a bit cakier and less chewy than the butter-based recipe. The edges were crisp and golden brown, while the centers remained chewy and soft.

Bake time: 12 minutes.

Coconut oil

The coconut oil chocolate chip cookies showed a marked difference from the original recipe, and were our least favorite. Since we used all coconut oil in the recipe, there was an underlying coconut flavor to the cookies.

Since coconut oil is rock hard when chilled, it’s impossible to cream it with sugar like you do with butter. And because we tested our other fats at room temperature, we also wanted to test the coconut oil at room temperature, which meant that the oil was completely liquefied. Thus when we beat the fat and sugar together the dough didn’t lighten in texture like it did in our cookies made with a solid fat. This certainly added to the coconut oil cookies’ denser texture.

Dough: The dough was much smoother than the original. It had a slight shine to it, and felt a little more oily. It did hold its texture when placed on the cookie sheet; and when baked, the cookies didn’t spread as much as the butter or vegan butter cookies.

Texture: The texture was also very different from the butter-based cookies. Coconut oil cookies were much cakier; and instead of spreading fairly flat, they had a large dome. The edges also weren’t quite as crispy and they didn’t brown as much as the butter (and vegan) butter ones. Additionally, they were very tender and soft, but crumbled a bit more than the other cookies when completely cool.

Bake time: 14 minutes.

 

Final thoughts

While it’s certainly possible to use different fats in gluten-free baking, understand that the end result won’t necessarily be the same.

It’s important to note that we tested these fats in a recipe that doesn’t require the fat to be chilled (such as pie crust); coconut oil would be even trickier to use in a recipe requiring solid/chilled/hard fat.

Our suggestion: if you’re looking for a dairy-free fat substitute in your gluten-free baking, choose a fat that most resembles the one used in the original recipe. For example, a recipe that calls for butter would be best made with a vegan butter substitute. For a recipe made with vegetable oil, you could use coconut oil in its place. In order to keep the recipes as much the same as possible, match your fat substitutions as best you can.

Finally, we recommend that you watch your baking times. We always provide time ranges for our recipes; when you’re using a fat substitute, start with the shorter time, and check every 1 to 2 minutes, until done.

 

And now we’d love to hear from you!

    Trying to make a healthier cc cookie. I have been using fresh, mashed avacado as a fat substitute. Eggs. I mix 4 different gluten free flours with still some regular flour. Have substituted date paste (water and dates in vitamix) and a little coconut sugar for brown sugar. Next will try subbing maple syrup, honey, maybe a little molasses for white sugar. Avacado has higher moisture content than butter so must add more dry ingredients. Will need another 3 tablespoons if going to honey, etc. I use 60% cocoa chips. Also add a tablespoon of cocoa. Soda, salt, vanilla and nuts. I make another change each batch and always write it down. All have been eatable but still looking for perfection😊.

    I have a grandson who is highly allergic to dairy. I also like Earth Balance vegan butter, but for chocolate chip cookies, I like Spectrum organic palm shortening. If you like a crisp chocolate cookies, this works well. For other cookies, I stick with Earth Balance. Hope this helps.

    This has nothing to do with gluten free baking but it is an interesting sidebar about moisture in baking. I was making refrigerator cookies (remember them?). You make the batter and roll it into a tube and enclose it in wax paper and chill. Then slice and bake. I used Crisco
    shortening. Well I had a hard time slicing them and they were crumbly sort of. I noticed a 1-800 number on the can so I called. The nutritionist said that Crisco does
    not have any water in it vs. butter that is part water. She suggested that I add a T. or so of water to the mixture. She was right!

      It’s true, Mary! Vegetable shortening like Crisco is 100% fat, unlike butter, which is about 80% butterfat. Oftentimes they can be used interchangeably in baking, but with slightly different results. If you’re curious, you can read more about the difference in baking with these two ingredients in our blog article on the topic. Happy baking! Mollie@KAF

    Has anyone ever used plain yogurt as a fat substitute? I’m wondering what that would be like? Thank you in advance for your replies.

      You can often times use a full-fat (whole milk) plain yogurt to replace some of the oil in recipes like muffins and quick breads. It tends to get more tricky if you attempt this swap in recipes like cakes, in which the fats can be partially responsible for creating the foundation of the cake. For recipes that call for vegetable oil, you can try replacing about 25-50% of it with yogurt to see how you like the results. Good luck! Kye@KAF

    Thanks for the article and information, you guys are the best at discovering what really works in baking. I’ve been working with a non-fat diet which has required me to learn how to bake without all three of the items in your study. I’ve ended up using a lot of ripe bananas and applesauce. Would you consider doing a study about that??

      Thanks for the comment, Cristine! So glad you’ve found our information helpful. While I’m not sure our plans to do a dedicated blog post around this topic, we have enjoyed experimenting with bananas and applesauce on our own as fat replacements. While we haven’t found that it works in all of our recipes or that it can replace 100% of the results, we’re pleased to know that it people like you have had success adapting the recipes to fit your lifestyle. Keep us posted with any more discoveries you make! – Alyssa

    I really enjoy KA muffin mix & use unsweetened applesauce for 1/2 the oil & occasionally
    use egg replacer & it works very well. The muffin mixes are great & convenient since I cook GF for one.
    Thanks,
    Bette

    Although I would like to use coconut oil for health reasons, I wonder how vegetable shortening would hold up as opposed to vegan butter?

      Donna, vegetable shortening is frequently called for in cookie recipes, and generally doesn’t spread as much as cookies made with butter, but should work fine. If you notice you’re not getting as much spread as you would like, you can pat the dough balls down a bit before baking. Barb@KAF

    My best result with making the gluten free and dairy free is using the g/f baking mix (Bisquick like) and the crisco sticks which are dairy free. I’m finding trial and error but these are by far the most like regular chocolate chip cookies.
