    Do you ever just get a craving for warm and gooey chocolate chip cookies? Mug cookies taste just like cake and are an easy way to get your cookie fix–without all the extra cookies to put away! 

    Sweet brown sugar gives this cookie just the right amount of sweetness that will be hard to say no to. Prepare this recipe whenever that late night sweet-tooth hits and you need a soft mug cookie ASAP! 

    When it comes to chocolate chips, I’m a little obsessed. My single serve edible cookie dough is made with crunchy chocolate chips and makes my mouth water. Every. Single. Time. Both are great options for whenever you need to treat yourself to a sweet treat.

    • Butter: Use either salted or unsalted butter for this recipe. If you’re using salted butter, keep this in mind as you add the salt as it could make it too salty. For a dairy-free option, use dairy-free butter. 
    • Brown Sugar: Dark or light brown sugar will work for this cookie and allow it to be moist and sweet. Of course, you can use regular white granulated sugar in its place. 
    • Vanilla: Pure vanilla extract is a classic ingredient for cookies, but you can experiment with different other types of extracts such as almond.
    • Salt: A little bit of salt balances this cookie out and makes sure the recipe is filled with plenty of flavor. 
    • Egg Yolk: One single egg yolk makes the consistency of this dessert cakey and rich. 
    • Flour: We like to use all-purpose flour for baking because it works so well. For a gluten-free version, use a 1:1 gluten-free flour with xanthan gum added to it.
    • Chocolate Chips: Milk chocolate or dark chocolate chips can be used! Want to switch things up even more? Use white chocolate chips. 

    Pro Tip: Vanilla extract is an essential ingredient for cookies! Pure vanilla enhances all of the flavors of the cookies and creates the perfect balance of a little bit of savory with sweet.

    1. Melt the Butter: First, place the butter in a microwaveable safe eight-ounce mug and place in the microwave for about ten seconds or until the butter is melted. 
    2. Mix: Next, gently place some brown sugar into the mug with the melted butter and gently stir with a spoon. Add the egg yolk and vanilla extract and mix until smooth. 
    3. Combine: Add the salt to the sugar and butter mixture, then add some flour to the mug. With a spoon or rubber spatula, mix all of the ingredients until just combined, but do not overmix! 
    4. Chocolate Chips and Microwave: Finally, fold the chocolate chips into the batter. Place the mug cake into the microwave and cook for thirty-five to forty seconds until the cookie has expanded and fluffed up. 

    Be careful not to over cook the cookie. Different microwaves will yield different results so be sure to check after the thirty second mark and every seven seconds after that.

    Serving and Storage

    If you manage to have any of this recipe leftover, just top the mug with aluminum foil or place the cookie in an airtight container. Store in the refrigerator for three days. 

    Serve this classic recipe with a scoop of your favorite cold ice cream like cookies and cream or vanilla. A glass of chilled milk would also taste incredible with this dessert in addition to a cup of hot tea or coffee. 
    You could also drizzle some homemade caramel sauce over this treat depending on how far you want to go.

    • In the microwave, melt the butter in an eight-ounce mug for 8-10 seconds. Carefully remove.
    • Mix in the brown sugar and salt (if using salted butter, you will not need as much salt).
    • Add the egg yolk to the sugar mixture and whisk until fully combined. Lastly, add the flour until no dry patches remain, being careful to not overmix.
    • Fold in the chocolate chips. Add more chocolate chips to the top of the batter if you would like.
    • Microwave for 35 – 40 seconds until the cake has risen and becomes fluffy. If the cookie is underdone, microwave it for 5-7 more seconds. It is better to undercook the cookie than overcook it. The texture should be soft and gooey in the center.
    • Serve with ice cream, caramel sauce, chocolate sauce, and much more!
