    ⭐Why I Love It:

    • Chewy M&M Cookie - By using an egg yolk and by not over baking the cookies, the insides stay perfectly gooey (without being raw!) and chewy.
    • Super Small Batch Recipe - I love that this single serve M&M cookie recipe makes only two large cookies. It lets me can satisfy my cookie craving without having to make an entire batch of cookies. Another favorite small batch cookie recipe is this Single Serve Chocolate Chip Cookie and Single Serve White Chocolate Macadamia Nut Cookie!
    • No Mixer Needed - Because it's such a small amount of dough, you can mix it all up by hand using a rubber spatula instead of needing to use an electric or stand mixer.

    🥘Ingredients

    Ingredients to make a small batch of M&M cookies in small glass prep bowls.
    • Unsalted Butter - Softened to room temperature! As long as your butter is softened, then you can easily mix up the dough by hand. If you use salted butter, just omit the amount of salt by half. When measuring the butter, I prefer to cut from the middle of the stick since the tablespoon markers at the ends of the stick can be off. For a small recipe, it's extra important to be accurate with measurements.
    • White Granulated Sugar
    • Brown Sugar - When measuring brown sugar, make sure to pack it into the measuring cup. You can use either light brown sugar or dark brown sugar.
    • Egg Yolk - Using only the egg yolk helps keep the recipe super small and it also gives the cookies their chewy/fudgy/almost gooey center. If you want to use up the leftover egg white, you can make this Single Serve White Cake or Single Serve Chocolate Cake recipe!
    • Vanilla Extract - For flavor!
    • All-Purpose Flour - When measuring flour, make sure to use the 'spoon and level' method. This is where you spoon the flour into the measuring cup and then level off the top. Instead of dipping the measuring cup directly into the flour bin which can lead to over measuring.
    • Baking Soda - This is the leavener for the cookie to help them rise.
    • Kosher Salt - I like the Diamond Kosher Salt. A small amount of salt is so important to balance the sweetness in cookies. If you use table salt, then I would cut the amount by half.
    • M&M Candies - I love to make this recipe for different holidays by using different colored M&M candies.

    See the recipe card for full information on ingredients and quantities.

    🔪How To Make Single Serve M&M Cookies

    This recipe for Single Serve M&M Cookies could not be any easier! Just mix up the dough in one bowl, pop in the fridge while the oven preheats, then bake on one sheet.

    Butter creamed with brown sugar, sugar, and egg yolk.

    Photo 1 - In a medium bowl, stir together the softened butter and sugars until combined (I like use a rubber spatula to ‘smoosh’ the mixture against the side of the bowl to really cream things together). Mix in the egg yolk and vanilla extract until well combined.

    Photo 4 - Bake until the edges are firm and set and the center is just set. Allow to cool for at least 10 minutes on the baking sheet so the cookies can finish cooking on the warm sheet. Enjoy!

    💭Recipe Tips

    • Softened Butter - In order to mix up the cookie dough, your butter needs to be softened to room temperature. If you're in a pinch you can microwave for just a couple of seconds, but be careful not to melt it!
    • Allow to Cool on Baking Sheet - Letting the single serve cookies cool on the baking sheet for 10 minutes lets the cookies finish baking on the warm baking sheet so they set up.
    • Don't Over Bake - The cookies will finish setting up on the baking sheet so in order to have the gooey (but not raw) insides be sure not to over bake them. The egg yolk helps give the center a gooey/fudgy interior so know that as long as they're set around the edges, golden on the bottom and golden brown/slightly set on top then they are baked 🙂
    • Use 'Spoon and Level' Method When Measuring Flour - When measuring flour, make sure to use the 'spoon and level' method. This is where you spoon the flour into the measuring cup and then level off the top. Instead of dipping the measuring cup directly into the flour bin which can lead to over measuring.

    👩‍🍳Recipe FAQs

    Why does the recipe use only an egg yolk

    Using only the egg yolk helps keep the single serve cookie recipe super small and it also gives the cookies their chewy/fudgy/almost gooey center. A great way to use the leftover egg white is in this single serve chocolate cupcake recipe!

    What is the 'Spoon and Level' method?

    The spoon and level method is best for measuring flour because it reduces the risk of over measuring. Start by fluffing up the flour int the container then use a spoon to spoon it into the measuring cup and use a knife to level off the top. This is much more accurate than scooping the flour directly from the container with the measuring cup.

    This Single Serve M&M Cookie recipe is a super small batch cookie recipe that is mixed up in one bowl with a rubber spatula (no mixer needed), loaded with M&M candies, and makes only two large chewy cookies. Perfect to satisfy your cookie craving!

    • Author: Kathleen Hansen
    • Prep Time: 5 minutes
    • Cook Time: 11 minutes
    • Total Time: 35 minutes
    • Yield: 2 large cookies
    • Category: Dessert, Cookies, Single Serve
    • Method: Oven
    • Cuisine: American

    Ingredients

    • 3 tablespoons unsalted butter, softened to room temperature
    • 3 tablespoons packed brown sugar, light or dark
    • 1.5 tablespoons white sugar
    • ¼ teaspoon vanilla extract
    • 1 egg yolk
    • ½ cup all-purpose flour
    • ¼ teaspoon baking soda
    • ¼ teaspoon kosher salt
    • ¼ cup M&Ms

    Instructions

    1. Prep - Get the oven preheating to 350 degrees F. Line a baking sheet with parchment paper.
    2. Mix Butter and Sugar - In a medium bowl, stir together the softened butter and sugars until combined (I like use a rubber spatula to ‘smoosh’ the mixture against the side of the bowl to really cream things together).
    3. Add Yolk and Vanilla - Mix in the egg yolk and vanilla until well combined.
    4. Add Dry Ingredients - Stir in flour, baking soda, and salt. Then mix in the M&Ms.
    5. Chill Dough - I like to pop the dough in the fridge for 15-20 minutes while the oven finishes preheating. 
    6. Roll into Balls - Roll the dough into two balls and place on a baking sheet. I like to use a large ⅓ cup cookie scoop (the same size I use to fill a standard muffin pan). I also like to press a few M&Ms on top of each.
    7. Bake - Bake for 11–13 minutes - until the edges are golden and set and the centers are just set. I like my cookies to have a gooey (not raw) center so they are extra tender, but you can adjust to your preferences.
    8. Cool on Baking Sheet - Allow the Cookes to cool on the baking sheet for about 10 minutes so they will finish cooking on the sheet and set up the final amount. Enjoy

    Notes

    Spoon and Level Method - When measuring flour, make sure to use the 'spoon and level' method. This is where you spoon the flour into the measuring cup and then level off the top. Instead of dipping the measuring cup directly into the flour bin which can lead to over measuring.

    Leftovers can be stored at room temperature, in an airtight container, for up to 1 week.
