Monster Cookies Recipe: Ingredients & Substitutions

Let’s discuss the ingredients, as well as possible substitutions, in this recipe.

• Salted Butter. Unsalted butter or coconut oil can be used in place of salted butter.
• Creamy peanut butter. I recommend using a variety of peanut butter that is solid at room temperature. You can also use crunchy peanut butter if you like the little pieces of nuts in your monster cookies.
• Eggs. Try to make sure the egg is room temperature! I have not made this recipe with an egg substitute, so if you do let me know in the comments below!
• Light brown sugar. If you like a little bolder, molasses taste then you can use dark brown sugar. Coconut sugar also works well.
• Granulated Sugar.Organic cane sugar is my granulated sugar of choice, but regular granulated sugar works perfectly.
• All-purpose flour. A 1:1 gluten-free all purpose flour can be used to make these cookies gluten-free.
• Fine sea salt. I only ever bake with pure, fine sea salt. If you are using iodized salt I recommend decreasing the amount of salt by half.
• Chocolate chips/M&Ms.The traditional mix-ins in monster cookies are chocolate chips and M&Ms. However you can choose to use whatever you’d like. Chopped peanut butter cups, peanut butter chips, white chocolate chips, etc.

How to Make Monster Cookies

These monster cookies are easy to make! We’ll walk through the process together and don’t forget to watch the video.

Begin by combing the flour, baking soda, sea salt, baking powder and cinnamon in a small bowl. Then, set it aside. Do not add the oats to this step, they are added in later.

Next, either in the bowl of a standing mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, beat the butter, peanut butter, brown sugar and granulated sugar together until light and fluffy.

Once the mixture is smooth, add the vanilla and egg and beat until combined.

Next, add the dry ingredient mixture and beat until combined.

Finally, add oatmeal, chocolate chips and M&Ms and stir until evenly distributed.

Once the monster cookie dough is finished, cover the bowl with plastic wrap, or transfer the dough to an airtight container with a lid and chill for at least 1 hour.

Portion & Roll Dough

Once the dough is chilled, preheat the oven. Use a small cookie scoop (1.5 to 2 TBS) to measure out the oatmeal cookie dough. Roll each portion into a smooth ball and place on a cookie sheet lined with parchment paper.

Once the dough balls are on the parchment paper, gently and ever-so-slightly press the tops down. This will ensure even baking. (NOTE: Dough will be slightly tacky, but should still roll easily into balls).

Bake

Bake the monster cookies in the preheated oven for 10-11 minutes, or until cookies are just barely set. Be very careful not to over-bake, or you run the risk of making dry cookies.

Cool

Once the monster cookies are baked, let them cool on the baking pan for 5-10 minutes, then transfer to a wire cooling rack to cool completely.

To Freeze the Dough

1. Form dough into balls.
2. Place cookie dough balls on a non-stick cookie sheet and put them in the freezer for 1-2 hours or until firm.
3. Transfer to an airtight, freezer-friendly container (I recommend either a glass storage container or a freezer-friendly ziplock bag).
4. Freeze for up to 1 month.
5. To bake: remove dough from the freezer and let it come to room temperature. Then bake according the the recipe instructions.

Store

Store these monster cookies in an airtight container at room temperature for 3-5 days (if they last that long)!You can also freeze baked cookies in an airtight container for up to 2 months.
