The Ultimate Guide to Egg Substitute for Cookies (and What to Use for Butter, Sugar, and More)

There’s nothing quite like the smell of fresh cookies wafting through your kitchen. But what happens when you’re halfway into mixing the dough and realize you’re out of eggs? Or maybe you’re baking for someone who’s vegan, allergic, or following a special diet. Whether you’re short on pantry staples or trying to make healthier choices, having the right substitutes on hand can save your cookies—and your day.

In this ultimate guide, you’ll discover exactly what to use as an egg substitute for cookies, along with alternatives for butter, sugar, and even flour. With smart swaps, you can still bake delicious cookies that rival your favorite bakery (yes, even cookies like Crumbl)—no eggs or butter needed.

Why You Might Need Substitutes in Cookie Baking

Picture this: it’s a cozy evening, and you’re craving a batch of warm, gooey cookies. You gather your ingredients only to realize you’re missing eggs. Or maybe you’re prepping cookies for someone who eats gluten-free, is managing diabetes, or simply doesn’t do dairy. Sound familiar?

Ingredient shortages, dietary restrictions, and lifestyle changes are more common than you think. With the rise of veganism and food sensitivities, more home bakers are exploring cookies without eggs, dairy, or refined sugar. And let’s face it—sometimes you just want to bake a healthier version of your favorite treat without sacrificing flavor or texture.

You don’t need to compromise. You just need the right swaps.

Best Egg Substitute for Cookies (Texture, Taste & Binding Compared)

When you’re baking cookies, eggs do more than bind ingredients. They also add moisture, richness, and structure. Choosing the best egg substitute for cookies depends on what kind of texture you’re aiming for.

1. Mashed Banana

• Use ¼ cup mashed ripe banana per egg.
• Works great for chewy cookies.
• Adds natural sweetness and a mild banana flavor.
• Best in oatmeal, peanut butter, or chocolate-based cookies.

2. Unsweetened Applesauce

• Substitute ¼ cup for one egg.
• Keeps cookies soft and moist.
• Ideal for cakey or tender cookies.
• Neutral in taste, but slightly sweet.

3. Ground Flaxseed (Flax Egg)

• Mix 1 tablespoon ground flaxseed with 3 tablespoons water. Let sit 5–10 minutes.
• Best for hearty, chewy cookies.
• Adds a nutty flavor and boosts fiber content.
• A top choice for anyone making egg substitute cookies that are also vegan.

4. Other Options: Chia Seeds, Silken Tofu, Yogurt, Aquafaba

Pro Tip: If you’re experimenting, test different egg swaps in small batches to see what works best for your recipe.

What’s the Best Butter Substitute for Cookies?

Butter brings richness and that classic cookie flavor, but plenty of alternatives get the job done—sometimes even better. Choosing the right butter substitute for cookies depends on the flavor and texture you’re going for.

1. Coconut Oil

• Replace in a 1:1 ratio.
• Yields crispy edges and a slight coconut flavor.
• Great for chocolate chip or tropical-flavored cookies.

2. Margarine or Vegan Butter

• Closest to real butter in both taste and consistency.
• Ideal for thick, soft cookies like Crumbl-style.
• Many plant-based versions are available.

3. Nut Butters or Applesauce

• Peanut butter, almond butter, or cashew butter gives dense, rich cookies.
• Unsweetened applesauce creates soft, cakey cookies.
• Perfect for cookies for diabetics or those watching their fat intake.

4. Greek Yogurt or Avocado

Use these if you’re looking for healthier options or reduced fat in your cookie recipes.

Brown Sugar Substitute for Cookies (When You’re Out or Avoiding Sugar)

Need a brown sugar substitute for cookies, but still want that warm, caramelized taste? You’re in luck—there are lots of sweet alternatives.

1:1 Swaps:

• Coconut sugar – dark, rich flavor, lower glycemic index.
• Maple sugar – subtle maple notes, great for fall baking.
• Date sugar – earthy flavor, high in fiber.

Low-Carb & Diabetic-Friendly Options:

• Erythritol – mild taste, zero calories.
• Monk Fruit – sweet and clean, best blended with erythritol.

Quick Fix:

• Mix 1 cup white sugar + 1 tbsp molasses = 1 cup brown sugar

Avoid using artificial sweeteners like sucralose, which can alter the texture and flavor in unwanted ways.

What Can You Use Instead of Baking Soda in Cookies?

Out of baking soda? No problem. The key is understanding how leavening agents work. Baking soda reacts with acid to create lift. If you’re looking for a substitute for baking soda in cookies, here are your best bets:

Try These Options:

• Baking powder: Use 3x the amount. For 1 tsp soda, use 3 tsp powder.
• Self-rising flour: Already includes leaveners. Great for drop cookies.
• Club soda: Use in small amounts to provide lift and moisture.

Keep in mind: Using more baking powder can slightly alter the flavor and cause puffier results.

Flour Swaps & Special Diet Options

Flour is the base of your cookie dough—but not all flours act the same. Whether you’re avoiding gluten or want a lower-carb option, here’s how to work with different flours for cookies with almond flour and beyond.

Popular Swaps:

• Almond flour: Rich and moist, perfect for low-carb cookies.
• Oat flour: Light and nutty, adds chewiness.
• Coconut flour: Absorbent—use less and add extra liquid.

Tip: For cookies for diabetics, almond flour paired with a natural sweetener like monk fruit is a winning combo.

Cookies vs Biscuits: Are They the Same?

If you’ve ever traveled outside the U.S., you’ve probably noticed something strange—cookies vs biscuits can mean very different things.

• In the U.S., “cookies” are sweet, soft, or chewy treats.
• In the U.K., “biscuits” are usually crisp, dry, and meant for dunking.
