20 Minute M&M Cookies (1)

If you’re craving cookies and want them RIGHT NOW, you’ve come to the right place. These cookies take just 20 minutes and are SO delicious. They also yield just 6 small cookies, so you don’t have to worry about having enough to feed a whole party just because you wanted a freshly baked cookie! These cookies are a sister recipe to my 20 minute chocolate chip cookies and are essentially just those but with a mix of chocolate and mini m&m’s.

small batch vs. 20 minute cookies

If you’ve looked around my blog, you might notice that I have some cookies that are “small batch” and some that say “20 minute” and yield a small batch. My 20 minute chocolate chip cookies were the first cookie that I developed as small batch, and they, like this recipe, use just 1 egg yolk to yield 6 cookies. However, I realized that not everyone wants extra egg whites sitting around, so I wanted to make my small batch cookies ones that used a whole egg. Using a whole egg would make sure that you weren’t leftover with any egg whites, and that you could scale them up super easily! However, when you’re looking for something super fast and a little smaller, these cookies will be around as well. If you need a quick way to use up that extra egg white you have from this recipe, you can check out my 20 minute double chocolate chip cookies!

recipe tips

weigh your ingredients

Weighing your ingredients is important for getting the recipe perfect and getting consistent results. Not weighing your ingredients can lead to adding too much or too little of an ingredient. If you haven’t already, I highly recommend purchasing a kitchen scale.This oneis super cheap and worked well for me when I was starting out!

mix the dough carefully

When adding in the flour, only fold the mixture just until no flour streaks remain. Overmixing the dough leads to more gluten formation, which can make the cookies super tough and chewy.

how to keep your cookies soft after baking

The secret to soft cookies is actually just underbaking them a little! Cookies continue baking after they have been taken out of the oven, so you shouldn’t pull them out once they look completely done. The cookies may look a little underdone at 10 minutes, but it’s important to take them out to keep them nice and soft. Let the cookies rest on the baking sheet for an additional 5 minutes before transferring them to a wire rack to cool (or just eat them right there!)

how to get perfectly round cookies

Wanna know the secret to perfectly round cookies? It’s cookie scooting! Right when the cookies come out of the oven, take a bowl, cup, or biscuit cutter that is just slightly larger than your cookies and place it over one of the cookies. Gently swirl the bowl around the cookie to make the cookie perfectly round (and slightly thicker). And that’s all there is to it!

ingredients and substitutions

All purpose flour:for structure and chewiness. If you’d like to make these gluten free, you can use a 1:1 gluten free flour such as Bob’s Red Mill or King Arthur.

Baking powder & baking soda:for helping the cookies rise.

Salt:to help balance and bring out the sweetness of the cookies

Unsalted butter:for tenderness and flavor. You can use salted butter in place of the unsalted, just be sure to omit the extra salt from the cookies. I highly recommend splurging a little and using European style butter here for the best flavor.

Light brown sugar:for sweetness and for moisture. We’re not going to use any granulated sugar here since these are fast and we want the maximum amount of flavor possible in the dough. Brown sugar will also help these cookies bake up a little thicker. You could also usedark brown sugarhere for some extra flavor!

Eggyolk:for binding and for moisture.

Vanilla:for flavor. I use and lovethis vanilla extract!

Chocolate:put your favorite chocolate here. I used Valrhona baking discs (these ones here) and can’t recommend them enough. Just look at those puddles! But they are definitely on the pricier side. If not using the discs, I recommend using a chocolate baking bar. You can also of course use chocolate chips here, just note that the cookies will most likely end up a little thicker. In terms of using milk, semi-sweet, or dark chocolate, use your favorite!

Mini m&m’s: the star of the show. Personally mini m&m’s > regular m&m’s but you can put whichever you prefer! If you choose to use regular sized m&m’s, I would use more since they won’t be as dispersed in the dough.

20 minute m&m cookies q&a

can I double these small batch m&m cookies?

Of course! Obviously they will not be small batch anymore but small batch isn’t always what we need! Simply double all of the ingredients in the recipe to make 12 delicious m&m cookies. I even more strongly recommend measuring by weight if you are going to double the recipe for the best results.

can I make these cookies ahead of time?

Definitely! Cookie dough only gets better with time. You can keep the cookie dough tightly covered in the fridge for up to 2 days before baking. For longer term storage, you can also freeze the cookie dough. Just be sure to take the dough out of the fridge at least 30 minutes to 1 hour before you want to bake, so that it becomes soft enough to scoop again!

how to store small batch m&m cookies

If for some reason you don’t feel like inhaling these 6 cookies (like I do), you can store them in an airtight container at room temperature. They will taste the best on the day that they are baked, but will keep fresh for up to 3 days.

why do you measure in grams?

My recipes are all written in grams because it is the most accurate way to bake. When you use a kitchen scale, you ensure that your baked goods turn out as close to the written recipe as possible. Plus, the cleanup is way easier when using a scale! I will provide standard cup measurements but please note that I have not tested the recipe using cup measurements and therefore can not guarantee your recipe will come out how mine did. Here is my favorite kitchen scale.

a note on oven temperature

Ovens vary and fluctuate in temperature and aren’t always at the temperature they claim to be. I highly recommend getting an oven thermometer if you love to bake, they are super helpful for letting you know when your oven might be lying to you! I use this one.

cookie troubleshooting

why did my cookies come out thick and crumbly?

If your cookies are thick, dry and crumbly, it’s most likely because you added too much flour. If you use cup measurements, it’s very easy to over-measure without even realizing it! I always recommend a kitchen scale(this one is super cheap and a great starter scale), but if that’s not an option for you, here’s the best way to measure flour: fluff up the flour with a fork, then use a spoon to fill up the measuring cup and level off the top with a knife.

why are my cookies crispy instead of soft?

The texture of these cookies should be quite soft, with slightly crisp edges. If the cookies are crispy, it could be that you added too much flour, but it’s most likely that you overbaked them. The cookies are done when the edges are slightly golden brown, and the middle looks like it’s just *almost* done setting. Your oven temperature may also be hotter than it claims to be, which is why I can’t recommend anoven thermometerenough.

Prep TimePrep Time 10 minutes minutes

Cook TimeCook Time 10 minutes minutes

Total TimeTotal Time 20 minutes minutes

ServingsServings 6 cookies


  • 50 g unsalted butter (3 ½ tbsp.)
  • 65 g light brown sugar (⅓ c.)
  • 1 egg yolk
  • ½ tsp. vanilla
  • 65 g all purpose flour (½ c.)
  • ¼ tsp. baking soda
  • ¾ tsp. baking powder
  • ¼ tsp. salt
  • 56 g mini m&m's (¼ c.) + extra for topping
  • 56 g semi sweet chocolate chips (¼ c. + 1 tbsp.)


  • Preheat the oven to 350°F / 175°C. Line a baking sheet with parchment paper or with a silicone mat.

  • In a medium sized microwave safe bowl, melt the butter in 20 second intervals, until it's *just* melted. The hotter the butter, the more the cookies will spread.

  • Add the light brown sugar into the butter and whisk until combined.

  • Add in the egg yolk and vanilla, and whisk until thoroughly combined.

  • Add in the flour, baking soda, baking powder, and salt. Use a rubber spatula to lightly fold the mixture together until there are only a few flour streaks remaining. Add in the mini m&m's and chocolate chips, and fold just until no flour streaks remain.

  • Use a 3 tbsp. cookie scoop to dish out the cookies and evenly space them out on the baking sheet. Bake for 8-10 minutes, or until the edges are golden and the middles of the cookies are almost completely set.

  • Immediately after taking the cookies out of the oven, you can take a bowl that is slightly larger than the cookies and swirl it around over the cookies to make them a little more uniform and circular. Serve and enjoy!
