Step-by-step process of making monster cookies

Step-by-Step Instructions

1. Preheat and Prepare

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone mats. This ensures even baking and easy cleanup.

2. Cream Butter, Peanut Butter, and Sugars

In a large bowl, beat together the softened butter and peanut butter until creamy and smooth. Add in both sugars and mix on medium speed until fluffy—about 2–3 minutes.

3. Incorporate Egg and Vanilla

Crack in the egg and add the vanilla extract. Beat until the mixture is smooth and fully combined.

4. Combine Dry Ingredients

In a separate bowl, whisk together the oats, flour, baking soda, and salt. Slowly add the dry mixture to the wet ingredients, stirring just until combined.

5. Add the Mix-Ins

Gently fold in the M&M’s, mini chocolate chips, white chocolate, and crushed pretzels. Reserve a handful of M&M’s and chocolate chips for decorating the tops of the cookies before baking.

6. Shape and Chill

Scoop the dough into balls—about 2 tablespoons each—and place them spaced evenly on the baking sheets. Slightly flatten each one. For best results, refrigerate the dough on the sheet for 20–30 minutes. This helps prevent excessive spreading.

7. Bake

Bake for 10–12 minutes, or until the edges are lightly golden but the centers are still soft. Do not overbake—these cookies will continue to set as they cool.

8. Cool

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. If desired, press additional M&M’s and sprinkles into the tops while they’re still warm.

Expert Tips for Perfect Monster Cookies

  • Use room temperature ingredients for better mixing and texture.
  • Don’t overmix the dough after adding flour; this helps keep the cookies soft.
  • Chill the dough to avoid flat cookies.
  • Make ahead by freezing cookie dough balls. You can bake them straight from frozen—just add 2 extra minutes to the baking time.
  • Add marshmallows or shredded coconut for an extra layer of flavor and texture.

Customization Ideas

The best thing about monster cookies is how easily you can personalize them. Here are a few ideas to make the recipe your own:

  • Nut-Free: Swap peanut butter with sunflower seed butter and avoid nut-containing candies.
  • Vegan: Use a flax egg and plant-based butter; ensure your chocolate is dairy-free.
  • S’mores Style: Add mini marshmallows and graham cracker bits.
  • Double Chocolate: Replace some of the flour with cocoa powder.

Serving Suggestions

These cookies are perfect on their own, but you can take them to the next level:

  • As ice cream sandwiches: Sandwich vanilla, chocolate, or strawberry ice cream between two cookies and freeze until firm.
  • Crumbled into trifles: Layer broken cookies with whipped cream and berries in small jars or cups.
  • Paired with coffee or iced milk: A great snack for both kids and adults.

Storing and Freezing

  • Room temperature: Store in an airtight container for up to 5 days.
  • Freezing baked cookies: Wrap tightly and freeze for up to 2 months.
  • Freezing unbaked dough: Shape into balls, freeze on a tray, then transfer to a bag. Bake from frozen as needed.

Frequently Asked Questions

Can I use quick oats instead of old-fashioned oats?

Yes, but your cookies may turn out slightly softer and less chewy. Old-fashioned oats provide better texture.

What if I don’t have M&M’s?

You can substitute with chopped chocolate bars, Reese’s Pieces, or any candy-coated chocolate. Just keep the red, white, and blue color theme if you’re going for a patriotic look.

Can I skip the pretzels?

Absolutely. They add a fun crunch and a hint of salt, but the recipe works just fine without them.

How far in advance can I make these?

You can make the dough up to 48 hours in advance and refrigerate it. Or, freeze shaped dough balls for up to 3 months.

Do I need a mixer?

A stand or hand mixer makes creaming the butter and sugar easier, but you can mix by hand with a little extra effort.

Can I use natural peanut butter?

Yes, but choose a no-stir variety for better results. Natural peanut butter can sometimes make the dough oily or affect consistency.

Press the dough into a greased 9×9-inch pan and bake at 350°F for 18–22 minutes or until golden. Cool and cut into squares.
