How to Make Cake Mix Monster Cookies

Step 1: Preheat and Prep

Start by preheating your oven to 350°F. Line a baking sheet with parchment paper or a silicone baking mat.

Step 2: Mix Wet Ingredients

In a large bowl, stir together the peanut butter, melted butter, and eggs until smooth and well combined.

Step 3: Add the Cake Mix

Dump in the cake mix and stir until everything is incorporated. The dough will be thick—don’t worry, that’s what you want.

Step 4: Fold in the Goodies

Add the quick oats, chocolate chips, and M&M’s. Gently fold everything together until evenly distributed. Try not to overmix.

Step 5: Scoop and Bake

Scoop out dough balls (about 1.5 tablespoons each) and place them a couple of inches apart on your baking sheet. Bake for 9–11 minutes, or until the edges are set and the centers are still slightly soft.

Step 6: Cool

Let the cookies cool on the baking sheet for about 5 minutes, then transfer them to a wire rack to finish cooling.

Pro Tips for Making the Recipe

• Don’t Overbake: These cookies firm up as they cool. Pull them out when the centers look slightly underdone for a soft, chewy result.
• Chill the Dough (Optional): If your dough feels too sticky to handle, pop it in the fridge for 15–20 minutes to firm up.
• Uniform Size: Use a cookie scoop to keep all your cookies the same size for even baking.
• Press Extra M&M’s on Top: After scooping the dough, press a few extra M&M’s on top of each cookie for a bakery-style look.

How to Serve

These cookies are so versatile—they’re great warm right out of the oven or cooled completely. Serve them:

On a Dessert Tray

Perfect for parties, bake sales, or potlucks.

With a Glass of Milk

A classic combo that never fails.

Ice Cream Sandwiches

Scoop some vanilla or chocolate ice cream between two cookies for a decadent treat.

Kid-Friendly Snack

Tuck one into a lunchbox or bring a batch to a playdate.

Make Ahead and Storage

Storing Leftovers

Store in an airtight container at room temperature for up to 5 days. They stay soft and chewy!

Freezing

Freeze the unbaked dough balls on a baking sheet, then transfer to a freezer bag. Bake straight from frozen—just add 1–2 extra minutes.

Reheating

Want that fresh-out-of-the-oven taste? Pop a cookie in the microwave for 10–15 seconds.

FAQs

Can I use crunchy peanut butter instead of creamy?
Yes! Crunchy peanut butter works great if you want a little extra texture and peanut crunch in your cookies.

Do I have to use M&M’s?
Not at all. Use any candy-coated chocolate or even chopped chocolate bars. You could even mix in mini marshmallows or toffee bits!

Can I make these gluten-free?
You can! Just use a gluten-free cake mix and make sure your oats are certified gluten-free.

Why is my dough so sticky?
This dough can be a bit sticky due to the peanut butter and melted butter. Letting it chill for a few minutes helps make it easier to handle.
