Ingredients You’ll Need for Monster Cookies

To make the ultimate Monster Cookies, you’ll need a handful of simple ingredients that come together to create the perfect blend of chewy, crunchy, and sweet. Here’s what you’ll need:

Butter (1 cup, softened)
The base of many cookie recipes, butter provides richness and helps create a soft, chewy texture in your Monster Cookies.
Peanut Butter (1 cup)
Creamy peanut butter is key to giving these cookies their signature flavor and helps bind the ingredients together while adding a bit of saltiness to balance the sweetness.
Brown Sugar (1 cup)
Brown sugar adds moisture and a slight caramel flavor that enhances the overall taste of the cookie.
Granulated Sugar (1/2 cup)
A bit of granulated sugar helps the cookies spread out while baking and adds sweetness.
Eggs (2 large)
Eggs provide structure and moisture, helping the dough hold together and giving the cookies their rich, soft texture.
Vanilla Extract (1 tsp)
Vanilla adds a subtle, warm flavor that complements the other ingredients and elevates the cookie’s taste.
Baking Soda (1 tsp)
Baking soda helps the cookies rise slightly and spread out while baking, giving them the perfect texture.
All-Purpose Flour (1 1/2 cups)
Flour gives the cookies structure and holds everything together, ensuring they don’t fall apart.
Old-Fashioned Oats (2 1/2 cups)
Oats are essential for giving Monster Cookies their chewy texture. Use old-fashioned oats for the best results.
Chocolate Chips (1 cup)
Choose your favorite chocolate chips—milk, dark, or semi-sweet. They’ll melt into gooey pockets of chocolate throughout the cookie.
M&Ms (1 cup)
The colorful candy pieces add crunch, sweetness, and a fun pop of color, making these cookies even more irresistible.
Optional Add-ins:
- Chopped Nuts (1/2 cup): If you like an extra crunch, add walnuts or pecans.

- Coconut Flakes (1/2 cup): For a tropical flavor and extra texture.

Step-by-Step Instructions for Perfect Monster Cookies

Follow these easy steps to make the perfect Monster Cookies that are chewy, crunchy, and absolutely irresistible!

1. Preheat the Oven and Prepare the Baking Sheets

Preheat your oven to 350°F (175°C).
Line two baking sheets with parchment paper or silicone baking mats to ensure the cookies don’t stick and bake evenly.

2. Cream the Butter and Peanut Butter

In a large mixing bowl, use an electric mixer or stand mixer to cream together the softened butter and peanut butter until light and fluffy (about 2-3 minutes).
This step helps form a smooth dough base and guarantees your cookies remain soft and chewy.

3. Add Sugars and Vanilla

Add the brown sugar, granulated sugar, and vanilla extract to the butter and peanut butter mixture.
Mix until the sugars are fully incorporated and the mixture becomes smooth and creamy.

4. Add Eggs

Add the eggs to the bowl one at a time, making sure to mix well after each addition.
The eggs help bind the ingredients together and contribute to the cookie’s soft texture.

5. Combine Dry Ingredients

In a separate bowl, whisk the all-purpose flour, baking soda, and salt until well combined.
Slowly incorporate the dry ingredients into the wet mixture, mixing only until everything is combined. Be careful not to overmix.

6. Stir in Oats, Chocolate Chips, and M&Ms

Fold in the old-fashioned oats, chocolate chips, and M&Ms using a spatula or wooden spoon.
The dough will be thick and packed with delicious mix-ins, so make sure everything is evenly distributed.

7. Portion the Dough

Use a cookie scoop or tablespoon to portion out the dough into balls about 1 1/2 inches in diameter. Space the dough balls about 2 inches apart on the prepared baking sheets to allow for spreading during baking.

8. Flatten the Dough Balls Slightly

Gently press each cookie dough ball down with the back of a spoon or your fingers to flatten them slightly. This helps the cookies bake evenly and achieve a nice shape.

9. Bake the Cookies

Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are golden brown, and the centers are just set. Be careful not to overbake them to ensure they stay soft and chewy.

10. Cool and Enjoy!

Allow the Monster Cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Enjoy your freshly baked cookies with a glass of milk or share them with friends and family!

Tips for Customizing Your Monster Cookies

Monster Cookies are incredibly versatile, and with a little creativity, you can customize them to suit your tastes. Here are some fun ideas to make these cookies even more special:

1. Change the Chocolate

Variety of Chocolate: Instead of using just regular chocolate chips, try mixing in different types of chocolate such as dark, white, or even peanut butter chips for a unique flavor combination.
Chocolate Chunks: Use chopped chocolate bars for big chunks of gooey melted chocolate in every bite.

2. Swap the Candy

M&Ms: While classic Monster Cookies feature M&Ms, you can try using other types of candy. For a fruity twist, swap them for Reese’s Pieces, Skittles, or even chopped candy bars like Snickers or Milky Way.
Candy Canes (for a festive touch): Crush candy canes to add a minty crunch during the holiday season!

3. Add Nuts for Extra Crunch

Walnuts or Pecans: Add 1/2 cup of chopped walnuts or pecans for an extra crunch and rich, nutty flavor.
Almonds: Sliced almonds are a great alternative if you prefer a more subtle nutty flavor.

4. Try Dried Fruit

Raisins or Cranberries: Dried fruit adds a chewy and slightly tart element that balances out the sweetness of the cookies. Try dried cherries or raisins for an unexpected twist.
Apricots or Figs: Chopped dried apricots or figs can add a unique sweetness and texture.

5. Make Them Gluten-Free

Gluten-Free Flour: Substitute the all-purpose flour with a 1:1 gluten-free flour blend to make the cookies gluten-free.
Oats: Be sure to use certified gluten-free oats, as regular oats can sometimes be contaminated with gluten.

6. Experiment with Different Nut Butters

Almond Butter or Cashew Butter: If you’re not a fan of peanut butter or want a different flavor, try using almond or cashew butter for a creamy twist.
Sunflower Seed Butter: For those with nut allergies, sunflower seed butter is a great alternative that still gives a rich, creamy texture.

7. Add Coconut Flakes

Sweetened or Unsweetened Coconut: Shredded coconut can add a tropical flavor and chewy texture. Use 1/2 cup of coconut flakes for a subtle touch or up to 1 cup for a more pronounced coconut flavor.

8. Spice It Up

Cinnamon or Nutmeg: Add 1/2 teaspoon of cinnamon or nutmeg to the dough for a warm, spiced flavor. This works especially well around the holidays.
Salted Caramel: Add a sprinkle of coarse sea salt on top of the cookies before baking for a sweet and salty flavor profile.

9. Make Them Healthier

Whole Wheat Flour: Swap half or all of the all-purpose flour for whole wheat flour to increase fiber content.
Reduce Sugar: Cut back on the sugar by 1/4 cup or use natural sweeteners like honey or maple syrup to make them a bit lighter.
Add Protein: Mix in protein powder or a scoop of collagen powder to boost the protein content without affecting the taste too much.

10. Make Them Mini

Mini Monster Cookies: If you prefer smaller portions, use a smaller cookie scoop and bake for 8-10 minutes to create bite-sized Monster Cookies. These are great for parties or kids!

How to Store and Keep Monster Cookies Fresh

Proper storage is key to keeping your Monster Cookies soft, chewy, and delicious for as long as possible. Here are some tips on how to store them and maintain their freshness:

1. Let Them Cool Completely

Before storing your Monster Cookies, allow them to cool completely on a wire rack. Storing warm cookies can lead to moisture buildup inside the container, causing them to become soggy or lose their texture.

2. Use an Airtight Container

For Short-Term Storage (Up to 1 Week): Place your cooled cookies in an airtight container. This helps retain moisture and keeps the cookies soft. You can layer the cookies with parchment paper in between to keep them from sticking together.
For Longer-Term Storage (Up to 3 Weeks): You can store them in a sealed jar or a plastic food storage bag. For added protection, wrap each cookie individually in wax paper or plastic wrap before placing them in the container.

3. Store at Room Temperature

Monster Cookies are best stored at room temperature for up to one week. Make sure they are kept in a cool, dry place, away from direct sunlight or heat sources.

4. Freeze for Longer Storage (Up to 3 Months)

If you want to keep your Monster Cookies fresh for a longer period, freezing them is a great option.

To Freeze Baked Cookies: make sure to let them cool completely first. Then, place them in a single layer on a baking sheet and freeze them for 1-2 hours until firm. After freezing, transfer the cookies to an airtight container or freezer bag. Label the bag with the date so you can keep track of how long they’ve been in the freezer.
To Freeze Cookie Dough: If you’d like to bake cookies fresh later, you can freeze the dough as well. Portion the dough into balls, place them on a baking sheet, and freeze until firm. Once frozen, transfer the dough balls into a freezer-safe bag or container. When ready to bake, simply bake straight from the freezer, adding an extra 1-2 minutes to the baking time.

5. Revive Softness

If your cookies become a bit hard after a few days, don’t worry! Simply place a slice of bread (preferably white or whole wheat) in the container with the cookies. The bread will help restore moisture, and the cookies will soften again. You can also microwave the cookies for 10-15 seconds to warm them up and bring back their fresh-baked softness.

By following these storage tips, your Monster Cookies will stay as fresh and delicious as the day they were made—ready to be enjoyed whenever the craving strikes!
