A single giant cookie that combines the nostalgic comfort of M&Ms, the richness of peanut butter, and the hearty texture of oats - this One Giant Monster Cookie is the ultimate answer to serious cookie cravings. At six inches in diameter, it's an impressive treat that transforms the classic monster cookie into a personal-sized indulgence perfect for sharing... or not!
Last weekend, I made this for a movie night at home. The look of pure joy on my partner's face when I brought out this massive cookie was priceless. We broke pieces off throughout the film, enjoying how the edges stayed crispy while the center remained deliciously chewy.
Essential Ingredients and Selection Tips
- Peanut Butter - Choose traditional brands like Jif or Skippy for best results. The stabilizers help maintain perfect texture
- M&Ms - Regular size works better than minis or mega size in this giant format
- Oats - Old-fashioned rolled oats provide the best texture and visual appeal
- Egg - The 2-tablespoon measure is crucial - too much egg will make your cookie cakey
Over years of baking, I've learned that measuring ingredients precisely becomes even more important when working with small-batch recipes like this one.
Detailed Instructions
- Perfect Setup
- 1. Start by preheating your oven to 325°F - this slightly lower temperature ensures even baking for a cookie this size. Line your baking sheet with parchment or a silicone mat. The lining is crucial as this large cookie tends to spread.
- Creating the Base
- 2. Beat your softened butter with both sugars until well combined and creamy. Don't skimp on this step - even in small quantities, proper creaming creates the perfect texture. The mixture should be noticeably lighter in color.
- Building Structure
- 3. Add your carefully measured beaten egg (just those 2 tablespoons!), vanilla, and peanut butter. Mix until they're fully incorporated. The mixture might look slightly curdled at first, but keep beating until it smooths out.
- Mix-In Magic
- 4. Fold in your M&Ms and chocolate chips gently. Some bakers swear by reserving a few M&Ms to press into the top just before baking - it creates that bakery-style look we all love.
- Shaping Your Giant
- 5. Scoop all that glorious dough onto your prepared baking sheet. Shape it into a mound in the center - don't worry about making it perfect. The heat will help it spread into a beautiful 6-inch circle.

Through countless batches, I've discovered that slightly pressing down the center of the dough mound helps achieve more even spreading.
The Art of Temperature Control
Understanding your oven's personality is crucial when baking a cookie this size. Every oven has hot spots, and with a cookie this large, those variations matter more. I've learned to rotate the baking sheet halfway through for even browning. If the edges brown too quickly, a piece of foil tented over the top works wonders.

Mastering Texture Variations
The final texture of your cookie can be customized to your preference. For a chewier cookie, pull it out when the edges are just set and the center still looks slightly underdone. For a crispier result, let it bake until the top is more evenly golden. The cookie will continue to set as it cools.
The Science of Giant Cookie Structure
The physics of baking changes when scaling up to this size. The weight of the dough affects how it spreads and bakes, requiring that slightly lower temperature. I've discovered that placing the rack in the middle position is crucial - too high and the top browns before the center sets, too low and the bottom can become too crispy. The peanut butter acts as a stabilizer, helping maintain structure throughout the extended baking time.
Mix-In Strategy
Strategic placement of mix-ins makes a huge difference in a cookie this size. I've learned to reserve about 1/4 of the M&Ms and chocolate chips to press into the top just before baking. This ensures even distribution and creates that appealing bakery-style look. Sometimes, I'll create a pattern with different colored M&Ms on top, making it even more gift-worthy. The heat from baking helps them settle perfectly into the dough.
Storage Solutions and Reheating
While this cookie is best enjoyed fresh, it maintains its quality for up to 5 days when stored properly in an airtight container. To refresh it, 10 seconds in the microwave brings back that just-baked texture. For make-ahead preparation, the shaped dough can be wrapped and frozen for up to 3 months - just add a few minutes to the baking time when baking from frozen.
Chef's Essential Tips
- Press additional M&Ms and chocolate chips into the warm cookie for a professional look
- Let the cookie cool completely on the baking sheet - moving it too soon can cause breaking
- For perfect slices, use a sharp knife warmed under hot water and dried well
Every time I make this giant cookie, I'm reminded that sometimes bigger really is better.
