🔪 Instructions
Check out how to make chocolate Halloween M&M cake mix cookies with these simple step-by-step instructions:
Preheat your oven to 350 degrees F and line a large baking sheet with parchment paper.
In a large bowl, mix together the cake mix eggs and oil until well combined. Stir in ½ cup of Halloween M&Ms until well mixed.
Use your hands to make about 30 even balls of dough; line them up on your baking sheet. The balls will be about 1-2 tablespoons worth of dough in size.
Top the dough balls with the remaining M&Ms. Bake for 10 minutes.
Let cool for 5 minutes on the baking sheet before transferring them to a wire rack to cool completely.
🍴 Recipe Tips
Dough consistency. If your cookie dough doesn't hold together well and appears to be too wet, add in ¼ cup of all-purpose flour. You want your dough to be thick enough that you can roll it into balls without it sticking to your hands.
Cake mixes. I use Devil's food cake, but you can use any type of cake mix for these chocolate cake mix cookies recipes. I just think that there's a poetic touch added when using Devil's food for a Halloween recipe but feel free to use other flavors like red velvet, yellow, cherry chip, etc.
Different M&Ms. I love the Hocus Pocus blend of M&Ms but any Halloween-themed M&M bag will do (even non-Halloween colors will work if you don't want it to be tied to a specific holiday).
