If you love cookies that are chewy, hearty, and bursting with chocolate, you’re in for a treat. Monster cookies are the ultimate indulgence—packed with oats, chocolate chips, and sometimes a few extra goodies like peanut butter or candy pieces. Each bite is a satisfying mix of textures and flavors, perfect for dunking in milk or enjoying straight from the tray.
Ingredients You’ll Need
These cookies are all about texture and flavor, so make sure your ingredients are ready. Fresh oats and quality chocolate make a big difference!
- 1 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 1 cup brown sugar, packed
- ½ cup granulated sugar
- 2 large eggs
- 2 tsp vanilla extract
- 1 ½ cups all-purpose flour
- 1 tsp baking soda
- ½ tsp salt
- 3 cups old-fashioned oats
- 1 ½ cups chocolate chips (or chunks for extra gooeyness)
- Optional: ½ cup M&Ms or chopped nuts for extra fun
Tip: Using a mix of chocolate chunks and chips creates pockets of gooey chocolate and bite-sized pieces.
Step 1: Cream the Butter, Peanut Butter, and Sugars
Start by beating the softened butter, peanut butter, brown sugar, and granulated sugar together until light and fluffy—about 2–3 minutes. Then, add the eggs and vanilla extract, mixing just until combined.
Pro Tip: Don’t rush this step! Creaming the butter and sugars properly gives the cookies their soft, chewy texture.
Step 2: Mix the Dry Ingredients
In a separate bowl, combine the flour, baking soda, and salt. Whisk lightly to ensure even distribution.
Gradually fold the dry ingredients into the wet mixture until just combined. Overmixing at this stage can make cookies dense.
Step 3: Add Oats and Chocolate
Fold in the oats and chocolate chips gently. If you’re adding M&Ms or nuts, fold them in here too. The dough will be thick, hearty, and slightly sticky.
Tip: For extra-large monster cookies, chill the dough for 20–30 minutes before baking. This prevents excessive spreading.
Step 4: Shape and Bake
- Preheat your oven to 350°F (175°C).
- Line baking sheets with parchment paper.
- Scoop dough using a large cookie scoop (about ¼ cup per cookie) and place 2 inches apart.
- Flatten slightly with the back of a spoon if desired.
Bake for 12–15 minutes, until the edges are golden and the centers are set but still soft. Remember: they continue cooking slightly after being removed from the oven.
Pro Tip: Avoid overbaking to keep the cookies chewy and soft in the center.
Step 5: Cool and Serve
Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack. This ensures they stay intact and chewy.
Monster cookies are perfect on their own, with milk, or even crumbled over ice cream.
Optional Decorating Tip: Sprinkle a few extra chocolate chips or candy pieces on top immediately after baking for a colorful, fun presentation.
Tips for the Perfect Monster Cookies
- Use old-fashioned oats: They give chewy texture compared to quick oats.
- Don’t skip chilling: Helps cookies stay thick and not spread too much.
- Mix chocolate types: Semi-sweet, milk, or even white chocolate for flavor variety.
- Storage: Keep in an airtight container at room temperature for up to a week, or freeze for longer storage.
