These Christmas Monster Cookies are a lot like a Kitchen Sink or Trash Can cookie. They are loaded with sweet white chocolate chips and chocolate morsels and a salty surprise in crushed pretzels. We really bring on the festive holiday season by adding Christmas M&Ms. Add in some oats, and these cookies are really monsters with all the filling, you will love them!

How to make Christmas Monster Cookies:

These cookies really are monsters, with everything that is going in them! They are loaded with all your favorite cookie fillings. Like most cookie recipes you want to mix your wet and dry ingredients separately before mixing them together. Once you mix them together you will start adding in the oats. Once the oats are mixed in you will start folding in the chips, pretzels and M&Ms. Be care not to overmix, as you do not want a lot of air getting into the batter. Roll into dough balls about 2-inch balls and place them on the baking sheet lined with parchment paper. Bake and then enjoy!

ingredients for Christmas Monster Cookies.

Directions:

Step One – Preheat oven to 350 degrees F. Prepare a baking sheet with parchment paper and set aside.

  • Cooking Tip – Parchment Paper helps prevent the chocolates and M&Ms from melting directly on the pan when baking.

Step Two – Place softened butter, brown sugar, and granulated sugar in a large mixing bowl. Using a electric mixer cream together sugar and butter. Add in vanilla extract and continue to mix until combined.

  • Cooking Tip: Don’t substitute sugars. Both sugars should be used to get the best buttery and soft cookie. You can make these cookies only with white sugar, they will still taste good but there will be a difference.

Tips and FAQ:

Don’t Over-Bake: It’s important to not over bake your cookies. When you remove your cookie they might not look done but they will continue to cook on the pan.

Don’t Over-Mix: Over mixing your cookies they could come out of the oven flat. Make sure to mix until just combined.

Freezing Cookie Dough: Place them on a sheet pan and into the freezer. This way they all freeze individually without getting stuck together.

Once they are frozen you can place them all in a large freezer bag together.

Baking Frozen Cookie Dough: Start by removing the cookie dough from your freezer.

Take out the cookie dough balls from the baggy and place on a baking dish to thaw.

Once the cookie dough is back to room temperature you can bake them according to directions.
