No Bake Monster Cookies Ingredients

You will need:

• 6 tablespoons butter, softened
• 6 tablespoons sugar
• ¼ cup brown sugar
• ¾ cup creamy peanut butter
• 6 tablespoons quick-cooking oats, pulsed in a food processor
• 1 teaspoon vanilla extract
• ½ teaspoon salt
• 1½ cups quick-cooking oats, not pulsed in the food processor
• 10 tablespoons miniature M&M’s, divided
• 1 cup semi-sweet chocolate chips
• 3 tablespoons heavy cream

PRO TIP: Pulsing the oats in the food processor is optional. If omitting this step, replace these oats with 6 tablespoons of all-purpose flour.

Substitutions and Additions

QUICK COOKING OATS: You can use old-fashioned oats instead, but the cookies won’t be quite as soft as if you use quick-cooking oats. 

CHOCOLATE CHIPS: As these will be melted, you could use regular chocolate broken into pieces rather than chocolate chips. 

MINIATURE M&M’S: If you can’t get hold of the mini M&Ms, you could use the full-size ones instead.

SUGAR: The brown sugar makes this recipe softer and moister, but it’s fine to just use white sugar if that’s what you have. Honey would be another good alternative to sugar.

PEANUT BUTTER: Other nut butter such as almond butter or cashew butter would be a good substitute in this recipe if needed.

How to Make No Bake Monster Cookies

STEP ONE: Prepare an 8-inch baking dish by lining it with either foil or parchment paper. Set aside.

STEP TWO: In a large mixing bowl, cream together the butter and sugars. Add the peanut butter and mix well.

PRO TIP: Make sure your butter is at room temperature and not melted, otherwise, it won’t blend with the sugars properly.

STEP THREE: Add in the 6 tablespoons of quick-cooking oats (pulsed in a food processor), vanilla, and salt. Slowly add the 1½ cups of oats. Fold in ½ cup of M&M’s.

STEP FOUR: Press the mixture into the prepared pan.

STEP FIVE: Melt the chocolate chips and heavy cream in a small bowl in the microwave, stirring every 30 seconds. Once the chocolate is smooth, spread it over the cookie dough mixture. Sprinkle with the remaining 2 tablespoons of M&M’s.

STEP SIX: Cover and refrigerate for at least 2 hours or until set. Cut into squares.

PRO TIP: Make sure you don’t skip the refrigeration step. The cookie bars need time to set, and it will make them much easier to cut once chilled.

How to Serve No Bake Monster Cookies

No-bake monster cookies are packed full of yummy ingredients that make a sweet treat for the whole family. These treats would also be a great after-school snack. Serve these no-bake cookies cold, or take them on the go. You could even enjoy them with a glass of milk or a homemade frosty to drink. 

Storage

With just a few simple steps, you can ensure your monster cookie bars are always as delicious as when they were first made. 

IN THE FRIDGE: You can store these monster cookie bites in an airtight container – or tightly in plastic wrap – in the fridge for up to two weeks. 

Keeping them wrapped tightly will prevent them from drying out, as well as maintain their flavor. Additionally, this will help keep them from absorbing odors or flavors from other food items in the refrigerator. 

IN THE FREEZER: Monster cookies freeze well for up to three months in an airtight container. Thaw overnight in the fridge. 

No-bake monster cookies are a scrumptious mashup of peanut butter, oats, chocolate chips, and M&M’s. This recipe is different from other monster cookie bars because these cookies also have a yummy layer of chocolate on the top. Such an easy treat to make, there is no need to turn on the oven for these monster cookie bites that are a great way to satisfy your sweet tooth.

FREQUENTLY ASKED QUESTIONS

Can I add other ingredients to this recipe? 

These no-bake monster cookie energy bites are perfect for customizing with your favorite mix-ins. Try chia seeds, flax seeds, or coconut.

Can I freeze these cookie bars? 

These monster cookies will freeze well stored in an airtight container for up to three months.

Could I turn this recipe into cookies rather than bars? 

We have not tried making them this way, but I can’t see why you couldn’t scoop them onto a baking sheet as energy balls or flattened them into cookies and chilled instead.
