Wondering why your vegan cookies go flat when baking? This post will explain some of the reasons that this can happen and how to prevent it from happening again in future.

Why Do My Vegan Cookies Go Flat? (1)

Ever pop a batch of cookies into the oven only to find they’re flat, greasy and glued to the tray when you take them out? I’m sure we have all been there at one point and it’s disappointing to say the least! I’ve created this post to help you get soft, fluffy cookies every time. I hope you find it useful!

Why do vegan cookies go flat?

Let’s take a look at some of the most common mistakes that might be causing your vegan cookies to go flat.

1. Your vegan butter or margarine was too soft

Using butter or margarine that’s too soft is probably the most common reason why vegan cookies go flat. This can happen if you’ve melted it, left it out of the fridge for too long before using, or it could simply be that your kitchen is too hot and humid. Using cold butter/margarine will create more air pockets and will help you get fluffy cookies rather than flat ones. Even for cookies that are supposed to spread, like my double chocolate cookies, it’s best to use your margarine straight from the fridge, otherwise the cookies might spread a bit too much.

It’s important to note that vegan margarine and vegan butter are not the same thing. Although they’re both made with oils, vegan butter has a higher fat content and lower water content than vegan margarine. It’s crucial to use the one that the recipe specifically calls for because using the wrong type of fat can alter the end result. You can check out my vegan butter post for more information about the difference between the two.

2. You didn’t use enough flour

Another common reason vegan cookies go flat is if the fat to flour ratio is off. This is likely to happen if you’re using cups to measure rather than a food scale. The way you measure a cup of flour today might be different than the way you measured a cup of flour yesterday. For best results and accuracy, always use a food scale to measure your cookie ingredients.

3. You didn’t chill the dough

Chilling the dough before baking helps to make the fat firmer. Doing this ensures that the butter/margarine takes longer to melt when it’s in the oven, meaning it will spread slowly and steadily.

You don’t need to chill the dough for all types of cookies- most of my recipes don’t require it. But for cookies where you need to hold the shape, it’s best to chill the dough first. If the recipe you’re using asks you to chill the cookie dough, don’t skip this step. It’s there for a reason!

4. You flattened the dough too much

In many of my cookie recipes, I roll the dough into balls then flatten them slightly before baking. If you don’t flatten them, they’ll end up like cakey cookie balls rather than soft, chewy cookies. However, if you flatten them too much, you’ll end up with flat, lifeless vegan cookies.

If a recipe asks you to flatten the cookie balls before baking, you generally want them to be roughly 1/2 an inch thick. For cut-out cookies like sugar cookies, read the instructions carefully for how thin you should roll the dough out. If the dough is too thin then the cookies won’t rise well.

5. You’re using the wrong type of sugar

Many cookie recipes call for a mix of brown and white sugar and there’s a good reason for this. White sugar helps the cookies to spread so if you use too much of it, you might end up with flat cookies. I have had a few comments from readers in the past saying they substituted the brown sugar in my cookie recipe for more white sugar and their cookies turned out flat. Always make sure to follow the recipe closely and for best results, avoid making substitutions.

6. You didn’t use any raising agent

To prevent flat cookies, you should always be using either self-raising flour, baking powder or bicarbonate of soda, depending on the recipe. The raising agents are what will give the cookies that extra lift and create a soft, fluffy texture.

If you’ve used a raising agent and are still getting flat cookies, check the use by date. Raising agents that have been in your cupboard for too long can lose their power over time.

7. Your oven is too hot

If your oven is too hot, the butter or margarine in your cookies will melt quickly, causing the cookies to spread too rapidly. This is a surefire way to get flat vegan cookies!

To make sure your oven temperature is accurate, you can use an oven thermometer. You’d be surprised at how many ovens run too hot or too cold! I use this thermometer from Amazon.

Your vegan butter or margarine was too soft

How do you keep cookies from flattening? ›

Why are my cookies spreading flat? ›

Excess Sugar and Fat

Measuring is key in baking. If your cookie contains excess sugar or fat, it will spread while baking. If your first batch of cookies spreads, try adding a few tablespoons of flour to help thicken the remaining dough.

How do you make cookies rise more? ›

Baking Powder. The type of leavening you use in your cookies doesn't just help them rise while baking, it affects their texture and structure too. Baking soda in cookies yields a denser cookie with craggy tops, while baking powder causes cookies to rise higher during baking for a cakier texture.

What makes cookies rise baking soda or baking powder? ›

Does adding more baking powder make cookies fluffier? ›

If you use baking soda and your cookies are flat, switch to baking powder as this helps puff up dough more, making your cookie fluffy.

To remedy this, buy an oven thermometer (it doesn't need to be an expensive one) so that you know what the temperature in your oven actually is.

What happens if you use almond flour in cookies? ›

Baking with almond flour: conclusions

Cookies and scones may spread more; cake, biscuits, and muffins may rise less. When you add almond flour to yeast-based recipes, bread or rolls will be moister and more tender — good if you're talking soft dinner rolls, not so good for crusty/chewy breads or pizza crust.

Should you chill cookie dough before baking? ›

Chilling cookie dough before baking solidifies the fat in the cookies. As the cookies bake, the fat in the chilled cookie dough takes longer to melt than room-temperature fat. And the longer the fat remains solid, the less cookies spread.

How do you keep cookies puffy? ›

Room temperature butter is just the right consistency to incorporate air when it's creamed with sugar. These trapped air pockets result in risen, fluffy cookies. If the butter is any warmer, it won't incorporate enough air and your cookies will have less rise.

What baking ingredient makes things fluffy? ›

Baking Soda

Once the dough has chilled, let it warm up at room temperature until it's just pliable (about 5 to 10 minutes).

What is the best sugar for cookies? ›

Granulated sugar

Using granulated white sugar will result in a flatter, crispier and lighter-colored cookie. Granulated sugar is hygroscopic, so it attracts and absorbs the liquid in the dough. This slows down the development of the gluten (flour), which makes the cookies crispier.

What is the secret to chewy cookies? ›
