Ingredients

- Box of chocolate cake mix – We used Devil’s food cake mix, but you can use any chocolate cake mix you like.
- Large eggs – Adds richness and helps to bind the dough for that perfect cookie texture.
- Melted butter – Gives the cookies a rich, buttery flavor and a soft, chewy texture.
- Vanilla extract – Enhances the chocolate flavor and adds a hint of sweetness.
- Mini chocolate chips – We used semi-sweet, but you can use milk, dark, or white chocolate chips for different flavor profiles.
- Mini M&M candies – Adds fun colors and just a little bit of crunch.
How to Make Easy Chocolate Cake Mix Cookies
Step One: Mix the Ingredients


- Preheat the oven to 350°F. Line baking sheets with parchment paper or silicone baking mats and set aside.
- In a large mixing bowl, combine the dry cake mix, eggs, melted butter, and vanilla extract. Stir ingredients until well combined and a thick dough forms.
- Gently fold in the mini chocolate chips and M&M’s candies until evenly distributed throughout the dough.
Step Three: Chill the Dough
- Cover the mixing bowl with plastic wrap and refrigerate the dough for at least 30 minutes, or overnight. Chilling the dough will enhance flavor and texture.
Step Four: Bake and Cool



- Once the cookie batter has chilled, using a medium-size cookie scoop, scoop out portions of dough onto the prepared baking sheets, spacing them about 2 inches apart.
- Bake the cookie dough balls, in your preheated oven, for 10-12 minutes, or until the edges are set and the tops of the cookies have a slight crust.
- Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a cooling rack to cool completely.

Tip: Do not overbake. The cookies may look doughy in the center but will firm up as they cool. This is what makes them stay soft.
Storing These Cookies
- Fridge: Store the cookies in an airtight container at room temperature for up to a week. There’s no need to refrigerate them.
- Freezer: You can freeze them too. Place the cookies in a single layer on a baking sheet until solid, then transfer them to a freezer-safe bag or container. They’ll keep well for up to 3 months. Let them thaw at room temperature or warm them up in the microwave for a few seconds.

Variations and Add-ins
- M&Ms – We used regular mini M&Ms, but you can swap them out for peanut, caramel, or crispy M&Ms for a different texture and flavor. You can use other colors too, red and green M&Ms for the holiday season or red and pink for Valentine’s Day, etc.
- Chocolate chips – We used regular semi-sweet chocolate chips, but you can use white chocolate chips, dark chocolate chips, or peanut butter chips for a fun twist.
- Nuts – Add a little crunch with chopped walnuts, pecans, or almonds. They pair perfectly with the rich chocolate flavors.
- Sprinkles – Mix in some colorful sprinkles for birthdays or other celebrations.
- Gooey caramel bits – Fold some small caramel pieces into the dough. They will melt as the cookies bake and give you little gooey pockets.
- Sea salt – Sprinkle a little sea salt on top of the cookies before baking. It adds a delicious sweet and salty flavor combo.
- Coconut flakes – Mix in some sweetened shredded coconut for a tropical twist.
- Toffee bits – Add some toffee bits for extra sweetness and crunch.
Top Tips for Making M&M Cookies
- This dough is fairly sticky, so make sure you always use a prepared cookie sheet because they tend to stick otherwise.
- Make sure not to overbake the cookies; they should stay soft and chewy.
- Stir in the mini M&M’s and chocolate chips by hand instead of using a mixer to avoid crushing the candies.
- Using a medium-sized cookie scoop helps you create evenly-sized cookies, but you can make them as big or small as you prefer.

Cake Mix Cookie FAQ’s
Yes, but use about ¼ or ⅓ cup of each instead of ½ cup. If there are too many the cookies won’t be able to spread properly.
Of course! The Devil’s Food Cake mix gives the cookies a rich, chocolatey flavor, but feel free to use any kind you want. If you want chocolate cookies but only have white or yellow cake mix, you can add 1/4 cup of unsweetened cocoa powder. This will give your cake the chocolate flavor you’re looking for. You’ll also want to add another tablespoon of melted butter.
These cookies have a soft texture and when warm, they are more delicate than some other chewy cookies. It’s best to let them cool completely on a wire rack before moving them around too much.
