Ingredients for chocolate chip cookie in a mug recipe no egg
Five minutes, one mug, and these simple ingredients transform into a warm, gooey cookie—no eggs required.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | ½ cup | Sifted for best texture |
| Unsweetened Applesauce 🍎 | ¼ cup | Unsweetened variety preferred |
| Granulated Sugar 🍚 | ¼ cup | Light brown sugar for depth |
| Packed Brown Sugar 🍚 | ¼ cup | For chewy texture |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla for flavor |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Baking Soda 🍞 | ¼ tsp | For lift and texture |
| Semi-Sweet Chocolate Chips 🍫 | ½ cup | Enjoy Life brand for vegan |
| Milk 🥛 | 2 tbsp | Any milk works here |
| Microwave-Safe Mug ☕ | 1 whole | 12-16 oz capacity preferred |
The applesauce is the star here—it replaces eggs perfectly while keeping the cookie tender. Trader Joe's has the best unsweetened variety, but any brand works as long as it's not sweetened. For the butter, full-fat is non-negotiable—it's what gives these cookies that rich, melt-in-your-mouth texture. The chocolate chips? Enjoy Life brand is my go-to for vegan options, but any semi-sweet will do. If you're feeling fancy, grab a 12-16 oz ceramic mug—it retains heat better than glass, but any microwave-safe mug works in a pinch.
No applesauce? Unflavored pumpkin puree works in a 1:1 swap, though the flavor will shift slightly. Running low on butter? Coconut oil melts just as well, though it has a different taste. The milk can be any kind—dairy, almond, or even coconut—but don't skip it entirely. It helps bind everything together. For a nutty twist, swap half the chocolate chips for chopped walnuts or pecans. And if you're really in a hurry, you can even melt the butter and chocolate chips together first—it saves a step and ensures perfect melting.
This cookie reheats beautifully—just pop it back in the microwave for 15-20 seconds if it cools down. Store leftovers in an airtight container for 3-4 days, though I've never had any last that long. The mug itself? Wash it right away—those chocolate chip remnants dry like cement. For extra indulgence, sprinkle a pinch of flaky sea salt on top before microwaving. Trust me, it takes this from good to next-level.

Step-by-step instructions for single-serve chocolate chip cookies
Here's how to create two perfect mug cookies with crisp edges and gooey centers—no eggs required.
Melt the Butter and Mix Wet Ingredients
Place the 0.5 cup unsalted butter in your microwave-safe mug. Microwave for 30 seconds on high, then stir until completely melted. Add the 0.25 cup unsweetened applesauce, 0.25 cup granulated sugar, 0.25 cup packed brown sugar, 1 tsp vanilla extract, and 2 tbsp milk. Stir vigorously for 20 seconds until the sugars fully dissolve and the mixture becomes smooth and glossy.
This step is where the magic happens—the applesauce replaces eggs by adding moisture and binding properties. If the mixture looks too thick, add 1 teaspoon of milk at a time until it reaches a pourable consistency. The goal is a thick batter that clings to the spoon but can still be easily stirred.
Combine Dry Ingredients for Perfect Texture
In a small bowl, whisk together the 0.5 cup all-purpose flour, 0.5 tsp salt, and 0.25 tsp baking soda. Sift the flour mixture directly into the wet ingredients in your mug. Use a fork to gently fold everything together until just combined—you should still see small flour streaks. Avoid overmixing, which develops gluten and makes cookies tough.
Here's the thing—this no-egg version relies on proper mixing to create structure. The baking soda will react with the applesauce and milk to create lift, while the flour provides the chewy texture we love in mug cookies. Fold in the 0.5 cup semi-sweet chocolate chips by hand using a spoon, making sure they're evenly distributed throughout the batter.
Microwave for Perfect Doneness
Microwave the mug on high for 60 seconds. Immediately after microwaving, let the cookie rest for 30 seconds—this prevents the center from becoming too soft. You'll notice the edges will be slightly underdone at this point, which is perfect because they'll finish cooking during the resting phase.
For the best results, use a toothpick to check doneness. It should come out with a few moist crumbs but no wet batter. If the center looks too soft, microwave for an additional 10-15 seconds. The cookie will continue setting as it cools, so don't overbake—we want that signature gooey center that makes mug cookies special.
Optional Customization and Serving
While the cookie is still warm, you can customize it with a sprinkle of flaky sea salt on top or a drizzle of melted chocolate. Let it cool for 1 minute before transferring to a plate—this makes it easier to handle while keeping it warm and delicious. The cookie will firm up slightly as it cools, developing that perfect balance of crisp edges and soft centers.
I like to serve these with a glass of cold milk or a cup of coffee. They're perfect for satisfying that late-night sweet tooth craving or providing quick energy on busy mornings. The beauty of this recipe is that you can make two perfect cookies in just minutes, with no mess and no cleanup—just pure, warm chocolate chip goodness.
Pro Tips For Making Chocolate Chip Cookie In A Mug Recipe No Egg
- MEASURE BROWN SUGAR RIGHT: I learned this the hard way—packed brown sugar is not the same as scooped. Use a spoon to press it firmly into the measuring cup, then level it off. Too much air = overly sweet, gummy cookies. (And don’t drain the bag—just scoop and pack.)
- MIX DRY INGREDIENTS FIRST: Skip the flour clumps by whisking the dry stuff—flour, baking soda, salt—before adding anything wet. I used to just dump and stir, and ended up with lumpy dough that didn’t spread right. Two minutes with a fork saves you from a sad, dense cookie.
- MICROWAVE IN BURSTS: High heat for 30 seconds, then let it sit for 10. Repeat. The first blast sets the edges, the rest cooks the center without burning. I was skeptical until I tried it—now my cookies aren’t rubbery or half-raw inside. (Yes, even if you’re impatient like me.)
- USE COLD BUTTER: Cut that unsalted butter into tiny cubes and refrigerate it while you prep. Melted butter makes the dough too soft, and your cookie will spread into a sad pancake shape. Cold butter = crisp edges and that classic cookie texture. (No, you can’t skip this.)
Creative variations of this chocolate chip cookie in a mug recipe no egg
Sweet Variations
Craving something extra decadent? Swap the semi-sweet chocolate chips for white chocolate chips or dark chocolate chunks (70% cacao or higher). I love adding ½ cup mini M&M's for a fun, colorful twist—just fold them in after the chocolate chips.
For a caramelized touch, stir in 2 tbsp chopped pecans or walnuts before microwaving. 🍫
Spiced Twists
Warm spices elevate this cookie to new heights. Add ½ tsp cinnamon and ¼ tsp nutmeg to the dry ingredients for a snickerdoodle-inspired flavor. For a chai-inspired version, mix in ¼ tsp cardamom and ¼ tsp ginger.
These spices blend seamlessly with the chocolate and add a cozy aroma that’s perfect for cooler evenings.
Nutty Upgrades
If you love texture, fold in ¼ cup chopped hazelnuts or almonds alongside the chocolate chips. For extra crunch, toast them first in a dry pan over medium heat for 3-4 minutes until fragrant.
I also love adding 2 tbsp chopped crystallized ginger for a sweet-spicy kick that pairs beautifully with the chocolate. 🌰
Flavor Boosters
Brighten the cookie with a splash of flavor: Add 1 tsp orange zest or ½ tsp almond extract to the wet ingredients for a sophisticated twist. For a tropical vibe, stir in ¼ cup shredded coconut along with the chocolate chips.
These additions keep the cookie’s signature warmth while adding exciting new dimensions to every bite.
Gluten-Free Adaptation
For a gluten-free version, replace the all-purpose flour with ½ cup gluten-free 1:1 baking flour (like Bob’s Red Mill). Add 1 tbsp cornstarch to the dry ingredients to improve texture.
The applesauce substitution remains the same, ensuring the cookie stays tender and delicious. This adaptation works perfectly for those with dietary restrictions without sacrificing flavor. 🌾

Frequently asked questions
Can I use something other than applesauce to replace the egg?
Yes! If you don't have applesauce, try 1 tbsp ground flaxseed mixed with 3 tbsp water (let it sit for 5 minutes to thicken) or ¼ cup unsweetened pumpkin puree. Both work well for binding and adding moisture, though the texture may vary slightly. The flaxseed option adds a subtle nutty flavor, which pairs nicely with chocolate.
Why does my cookie turn out too dense or dry?
This usually happens if you overmix the batter or undercook it. Stir the dry ingredients just until combined to avoid developing gluten, which makes cookies tough. For microwaving, start with 60 seconds and check doneness with a toothpick—it should have a few moist crumbs but no wet batter. If it's still undercooked, microwave for 10-15 more seconds.
Can I make this recipe in an oven instead of a microwave?
Preheat your oven to 350°F and spoon the batter into a greased mini muffin tin (or small ramekins). Bake for 10-12 minutes until the edges are golden. The oven method gives you slightly crispier edges, but the microwave version is still gooey and perfect for single servings. For best results, use a light-colored mug—it absorbs heat more evenly.
How do I store leftover mug cookies?
Let the cookies cool completely, then store them in an airtight container at room temperature for up to 3-4 days. For longer storage, wrap them individually in plastic wrap and freeze for up to 1 month. To reheat, microwave for 10-15 seconds to restore that warm, gooey texture. The cookies will firm up slightly but still taste delicious!
What's the best mug to use for this recipe?
Use a 12-16 oz microwave-safe mug made of ceramic or tempered glass—these materials distribute heat evenly. Dark-colored mugs can make the cookie cook unevenly, so opt for light colors if possible. Avoid metal mugs, as they can cause sparks in the microwave. A mug with a handle makes it easier to remove from the microwave safely after cooking.
