Is egg necessary in cookies?

Cookies are a beloved baked good that can be found in almost every culture around the world. They come in a variety of shapes, sizes, and flavors – but most traditional cookie recipes call for at least one egg. So why is egg such a common ingredient in cookies? Is it really necessary, or can you make good cookies without eggs?

The Role of Eggs in Cookie Recipes

Eggs serve several important purposes in cookie recipes:

  • Structure – Eggs help give cookies their characteristic soft, chewy texture. The proteins in eggs coagulate when heated, helping to set the structure of the cookies.
  • Binding – Eggs act as a binder to hold the wet and dry ingredients together in a cookie dough. This helps the cookies keep their shape during baking.
  • Color & Browning – The proteins and fats in eggs promote browning and give cookies a lightly golden color during baking.
  • Moisture – Eggs add moisture to the dough, resulting in softer, chewier cookies. The fat in egg yolks also prevents cookies from drying out.
  • Rising – Eggs help leaven cookies slightly, giving them some lift as they bake.
  • Flavor – Eggs contribute a light egg flavor and richness to cookies.

So in traditional recipes, eggs play an important role in giving cookies their classic characteristics. Omitting eggs or replacing them with something else will change the makeup of the cookie dough and finished cookies.

Are Eggs Absolutely Necessary for Cookies?

While eggs certainly help make great cookies, they are not always 100% necessary in every cookie recipe. There are ways to bake cookies without eggs:

  • Replace each egg with 1-2 tbsp oil, butter/margarine, applesauce, mashed banana, or commercial egg replacer.
  • Use a flax or chia “egg” – 1 tbsp ground flax or chia seeds whisked with 2.5 tbsp water.
  • Add a little extra leavening agent like baking powder or baking soda to help the cookies rise without eggs.
  • Use milk, yogurt, pumpkin puree, or cottage cheese for moisture in place of eggs.
  • Substitute all-purpose flour for up to 1/4 of the flour in a recipe with oat flour or nut flour to improve texture.
  • Add a few tablespoons of corn starch to help bind the dough together.

However, removing eggs from a cookie recipe will alter the final product. Eggless cookies may spread more, be more dense, drier, chewier, or more crumbly. The flavor will also be less rich without egg yolks. You may need to tweak other parts of the recipe to compensate when omitting eggs.

Types of Cookies That Require Eggs

While it’s possible to bake eggless cookies, certain styles of cookies depend more on eggs for their signature texture:

  • Chocolate Chip Cookies – The eggs help chocolate chip cookies achieve their soft, chewy texture and golden color. Replacing eggs makes them flatter and cakier.
  • Sugar Cookies – Eggs give sugar cookies their signature tenderness and help them hold their shape when cut out. Eggless sugar cookies will be crumbly and fragile.
  • Oatmeal Cookies – The binding power of eggs helps keep oatmeal cookie dough together. Too many oats without eggs makes them dry and crumbly.
  • Peanut Butter Cookies – Eggs balance out the dense peanut butter in this dough. Removing them makes peanut butter cookies drier with a much denser, pasty texture.
  • Gingerbread Cookies – The molasses and spices in gingerbread cookies means they require the moisture and rising effects eggs provide. Eggless versions may not spread enough and can be dry.

For these cookie styles, it’s best to keep the eggs in the recipe, otherwise the texture and mouthfeel may not be quite right. If you need to replace the eggs, use an equal ratio egg substitute and adjust the other ingredients as needed.

Types of Cookies That Can Be Made Without Eggs

On the other hand, some cookie recipes work fine without eggs or only need small tweaks:

  • Shortbread Cookies – The high fat, low moisture content means shortbread holds together fine without eggs. It will be slightly more crumbly and delicate.
  • Biscotti – These twice-baked Italian cookies have enough structure from their low moisture content and stiff dough that eggs aren’t essential.
  • Florentine Lace Cookies – The crisp, delicate wafer-like texture of these cookies comes from sugar, butter, and flour – no eggs needed.
  • Icebox/Refrigerator Cookies – The long chill allows the dough to firm up properly without eggs.
  • Rolled Oats Cookies – Quick oats have enough binding power on their own to make these cookies hold together when shaped.

For these types, you can usually omit the eggs without drastically altering the final cookie. You may need to add a touch more liquid or binding agent, but the recipes work fine eggless.

Best Egg Substitutes for Baking Cookies

If you do want to bake cookies without eggs, which ingredients make the best substitutes? Here are top options:


Replacing each egg with 1/4 cup unsweetened applesauce is one of the most popular egg substitutions for baking. The moisture helps bind the dough, while the pectin adds structure. Be aware applesauce cookies will have a hint of apple flavor.


Mashed ripe banana can substitute for eggs in a 1:1 ratio. Bananas act as a binder and add moisture just like eggs. Banana also improves the texture. Cookies may have a mild banana flavor.


Vegetable oil, canola oil, melted coconut oil, or other neutral tasting oils make an easy egg replacement. Use 2-3 tablespoons oil per egg omitted. The fat replicates the moisture of eggs without changing flavors.

Ground Flax or Chia Seeds

When combined with water, the mucilaginous (gel-like) properties of ground flax or chia bind ingredients together. Use 1 tablespoon seed + 3 tablespoons water per egg. Be aware this may add a nutty flavor.

Commercial Egg Replacer

Special powdered egg replacer products like Ener-G Egg Replacer allow you to bake without eggs. Simply whisk the powder with water following package directions. Adds moisture without egg flavor.

Vinegar + Baking Soda

Activate baking soda by mixing with vinegar or lemon juice to help cookies rise. Use 1 teaspoon of each per egg omitted. Be careful adding too much soda, which can give a soapy taste.

How Do Eggless Cookies Compare?

When bakers make cookies without eggs, how does it impact the final product? Here’s how eggless cookies typically compare:

Characteristic Cookies with Eggs Eggless Cookies
Texture Soft, chewy Cakier, crisper, crumblier, flatter
Moisture Moist, tender Drier
Color Lightly golden brown Paler
Spread Hold shape when baked Spread more/flatten out
Rise Some lift Less rise
Binding Stays together well Crumblier, doesn’t hold together as much
Flavor Richer, eggy taste Less flavor depth

As this comparison shows, eggless cookie dough tends to produce different results than traditional recipes. Cookies without eggs won’t have quite the same characteristics unless other ingredients are adjusted accordingly.

Recipe Experimentation

When formulating an eggless cookie recipe, be prepared for some trial and error to get the texture and flavor right. Here are some tips:

  • Add a few extra tablespoons of liquid if the dough seems too dry.
  • Try an extra 1/4 tsp baking powder or soda for more rise.
  • Reduce oven temperature 25 degrees F to prevent over-browning.
  • Chill dough thoroughly to help prevent spreading.
  • Swap up to 1/4 of the all-purpose flour for oat flour or almond flour for more structure.
  • Stir in a couple tablespoons corn starch to help bind the dough.
  • Fold in a mashed ripe banana, yogurt, or pumpkin puree for moisture and binding.
  • Brush cookies with milk or cream before baking for extra browning and sheen.

Be willing to tweak a recipe 2-3 times until you achieve the perfect eggless cookie for your needs. The results will depend on the specific ingredients and proportions in a recipe.

Best Cookie Recipes to Bake Eggless

Looking for inspiration for eggless cookies to try baking? Here are some top recipes that work well without eggs:

Eggless Sugar Cookies

The simplicity of a basic sugar cookie dough means you can easily leave out the eggs. Swap in yogurt or milk to retain moisture and shape.

Eggless Oatmeal Raisin Cookies

Quick oats naturally help bind and add structure once baked. The raisins also provide moisture to keep these eggless cookies soft.

Eggless Shortbread Cookies

Buttery shortbread doesn’t require eggs to give it that delicate, crumbly texture. An extra spoonful of cream or milk is sufficient.

Eggless Peanut Butter Cookies

Dense peanut butter has enough moisture on its own to make these cookies stick together. Reduce oven temperature so they don’t dry out.

Eggless Ginger Molasses Cookies

For eggless ginger cookies, substitute the eggs with pumpkin puree or Greek yogurt to provide moisture and binder. The molasses keeps them chewy.

Eggless Cookie Ideas for Special Diets

Eliminating eggs from cookies makes them accessible for more diets and restrictions including:

  • Vegan – Ditching eggs allows you to make cookies without any animal products for a vegan treat.
  • Dairy-free/Lactose-free – Those avoiding milk can enjoy cookies without eggs or dairy.
  • Nut-free – Cookies without eggs can provide a safe treat for nut allergies by avoiding almond or peanut flours.
  • Egg Allergies – People with egg allergies can satisfy their cookie cravings with egg-free recipes.

Get creative mixing and matching egg substitutions like banana, applesauce, or flax eggs to whip up allergy-friendly cookies the whole family can enjoy.

Storing Eggless Cookie Dough or Baked Cookies

How does omitting eggs impact storing cookie dough or keeping baked cookies fresh? Here are some tips:

  • Refrigerate eggless cookie dough up to 5 days – the chill helps bind moisture.
  • Freeze eggless dough up to 3 months.
  • Eggless cookies may not stay as soft but can be stored airtight at room temp up to 1 week.
  • Freeze baked eggless cookies up to 3 months to preserve freshness.

The lack of eggs means the dough won’t last as long before baking. And eggless baked cookies tend to firm up faster. For maximum freshness, chill or freeze dough and cookies.


At the end of the day, cookies can certainly be made without eggs. While eggless cookies won’t mimic the exact taste and texture of traditional recipes, they can still be tasty when done right. Get creative with your favorite cookie style by trying apple sauce, banana, or chia seeds as substitutes.

However, for classics like chocolate chip, chewy gingerbread, and soft oatmeal cookies, keeping the eggs in the recipe just makes them better. The binding, moisture, structure, and richness eggs provide helps these cookies achieve their signature consistency that is hard to duplicate eggless. But the versatility of cookies means bakers can experiment to find or customize the perfect eggless cookie variation for their dietary needs.
