Ingredients

• 6 tablespoons butter, softened
• 6 tablespoons sugar
• ¼ cup brown sugar
• ¾ cup creamy peanut butter
• 6 tablespoons quick cooking oats, pulsed in food processor
• 1 teaspoon vanilla extract
• ½ teaspoon salt
• 1½ cups quick cooking oats, not pulsed
• 10 tablespoons miniature M&M’s, divided into 8 tablespoons and 2 tablespoons
• 1 cup semi-sweet chocolate chips
• 3 tablespoons heavy cream

Each ingredient has a role in texture, flavor, or appearance. Butter and sugars create a rich, sweet base, while peanut butter adds flavor and moisture. Oats contribute chewiness, chocolate chips add gooey chocolate bursts, and M&M’s give color and crunch. Heavy cream helps bind the ingredients, giving the cookies a soft and cohesive texture.

Preparation Method

Follow these steps to make perfect No-Bake Monster Cookies:

Step 1: Prepare the Base

In a large mixing bowl, combine softened butter, sugar, and brown sugar. Beat together until smooth and creamy. Add peanut butter, pulsed oats, vanilla extract, and salt. Mix until fully incorporated.

Step 2: Add Whole Oats and Chocolate

Stir in the unprocessed oats and 8 tablespoons of miniature M&M’s. Fold in the semi-sweet chocolate chips and heavy cream. Mix gently until all ingredients are evenly distributed, ensuring each cookie will have plenty of chocolate and M&M’s.

Step 3: Form the Cookies

Line a baking sheet or tray with parchment paper. Using a cookie scoop or spoon, drop heaping tablespoons of cookie mixture onto the parchment paper. Gently flatten each cookie slightly with the back of the spoon or your fingers. Sprinkle the remaining 2 tablespoons of M&M’s on top for decoration.

Step 4: Chill to Set

Place the cookies in the refrigerator for at least 30–60 minutes to firm up. The chilling process allows the cookies to hold their shape without baking. Once set, they are ready to serve.

Step 5: Serve

Enjoy these cookies straight from the fridge for a chewy, chocolatey treat. They pair wonderfully with milk, coffee, or tea, making them perfect for dessert or an afternoon snack. Store leftover cookies in an airtight container in the refrigerator for up to one week.

Tips for the Perfect No-Bake Monster Cookies

1. Pulse some oats: Pulsing a portion of the oats ensures the cookies stick together better while keeping some texture from the whole oats.
2. Softened butter: Ensure butter is softened, not melted, for proper mixing and texture.
3. Adjust sweetness: Modify the amount of sugar or chocolate chips to suit taste preferences.
4. Keep M&M’s colorful: For a fun visual, sprinkle a few on top before chilling.
5. Firmness: If cookies are too soft after chilling, leave them in the fridge for an additional 30 minutes.

Nutritional Benefits

While these cookies are a sweet treat, they provide some benefits. Peanut butter adds protein and healthy fats, oats contribute fiber, and chocolate provides antioxidants. Portion control is key for enjoying them as a fun and indulgent snack without overindulging.

Variations

• Nut-free: Substitute sunflower seed butter for peanut butter.
• Extra chocolate: Add white chocolate or dark chocolate chips for variation.
• Festive themes: Use colored chocolate candies for holidays or parties.
• Coconut twist: Fold in shredded coconut for added texture and flavor.
• Mini cookie bites: Make smaller cookies for bite-sized snacks or lunchbox treats.
