Christmas Monster Cookies Ingredients
To make this recipe, you will need butter, brown sugar, granulated sugar, egg, creamy peanut butter, vanilla extract, all purpose flour, baking soda, salt oats, M&M’s, white chocolate chips and holiday sprinkles.
How Do You Make Monster Cookies?
Preheat the oven, and line a baking sheet with parchment or a nonstick baking mat. Cream the butter and two types of sugar in a large bowl with a mixer until fluffy. Add the egg, peanut butter and vanilla to the bowl, then mix to combine. Next add the flour, salt and baking soda, and mix until just combined. Stir in the oats, M&M’s and chocolate chips. Make cookie dough balls, and dip each ball into the sprinkles. Press a few more M&M candies and chocolate chips into the top of each ball of dough. Place the dough on a cookie sheet. Bake until the cookies are set and golden brown, then cool on a wire rack. Store the baked cookies in an airtight container, or enjoy right away.
Tips For The Perfect Cookies
- For the prettiest cookies, press some extra M&M’s and white chocolate chips into the tops of the balls of dough before baking. It’s a bit of a tight fit with the sprinkles in the mix too, but it’s totally worth it for a beautiful end result.
- The cookie dough can be stored in the fridge for up to 3 days before baking. If you’re planning to make your dough ahead of time, you may want to omit the M&M’s and add them just before baking so that the color from the candies doesn’t stain the dough if it’s in the fridge for a while.
- Look for white chocolate chips that contain cocoa butter rather than palm oil for the best flavor.
- These cookies will stay fresh in an airtight container at room temperature for 5 days.
- I recommend using a creamy peanut butter such as Skippy or Jif. Natural peanut butter does not work well in this recipe.
Quick Tip
Use a cookie scoop or a tablespoon measure to make sure all of your cookies are the same size

The recipe says baking soda, while the video says salt. Which is it?
It’s baking soda, thanks for catching that!
Can you omit the oatmeal? Was planning on doing oatmeal choc chip and didnt want to do two oatmeal cookies!!
I would be hesitant to omit the oatmeal because it could make the dough too wet, I haven’t tested it this way myself.
Okay, thank you! Maybe I will test with a different add on like pretzels!
