How to Prepare Monster Cookies
Now, let’s get our hands dirty and prepare these scrumptious Monster Cookies! Follow these simple steps, and soon you’ll have a batch of cookies that will make everyone happy!
Preheat and Prepare
First things first, preheat your oven to 350°F (175°C). This is vital for getting that perfect bake! While the oven warms up, line two baking sheets with parchment paper or silicone baking mats to prevent sticking. Trust me, this makes cleanup a breeze!
Mix the Dry Ingredients
In a medium bowl, combine 1½ cups of old-fashioned oats, ½ cup of all-purpose flour, ½ teaspoon of baking soda, and ¼ teaspoon of salt. Stir these dry ingredients together until they’re well mixed. This step ensures an even distribution of flavors throughout your cookies!
Cream the Wet Ingredients
Now it’s time to cream the wet ingredients! In a large mixing bowl, beat together ½ cup of softened unsalted butter, ½ cup of creamy peanut butter, ½ cup of granulated sugar, and ½ cup of light brown sugar until the mixture is creamy and smooth. You want it to look fluffy and pale—this is the key to a delightful texture!
Combine Ingredients
Add in 1 large egg and 2 teaspoons of vanilla extract to your creamy mixture, mixing until everything is well combined. Then, gently fold in the dry ingredients you set aside earlier. Be careful not to overmix—just stir until you see no more flour streaks. This keeps your cookies nice and tender!
Fold in the Goodies
Now for the fun part! Gently fold in ¾ cup of chocolate chips and ¾ cup of chocolate candy-coated pieces. Use a spatula to mix them in without breaking them apart. Every bite will be a delightful surprise!
Scoop and Bake
Scoop the dough into 2-tablespoon portions and place them on your prepared baking sheets, leaving about 2 inches between each cookie. Bake in the preheated oven for 10 to 12 minutes. Keep an eye on them; you want the edges to turn lightly golden while the centers remain soft and chewy!
Cool and Enjoy
Once they’re out of the oven, sprinkle a little flake sea salt on top while they’re still warm. Let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. The salty-sweet combo is simply irresistible!

Tips for Success
To ensure your Monster Cookies turn out perfectly every time, I’ve got a few handy tips to share! First off, measuring your ingredients accurately is crucial. Use the spoon-and-level method for flour—scooping directly can lead to too much flour, making your cookies dense. Trust me, no one wants a brick of a cookie!
Next, always let your butter soften at room temperature. This helps achieve that creamy texture we love. If you forget, you can microwave it for just a few seconds, but be careful not to melt it!
Cooling times are also important. Don’t rush to transfer the cookies from the baking sheet too soon; give them that 5-minute rest to set up. This helps keep them chewy instead of crumbly. And remember, the cookies will continue to cook slightly while cooling on the sheet!
Finally, don’t skip the flake sea salt topping! It elevates the flavor and adds a delightful burst of contrast. Happy baking!
Variations of Monster Cookies
One of the best things about Monster Cookies is how easily you can customize them to fit your taste! Want to add a little crunch? Toss in some chopped nuts like pecans or walnuts for a delightful texture. If you’re a chocolate lover, try swapping out the chocolate chips for white chocolate or even dark chocolate chunks for a richer flavor. You can also mix in dried fruits like cranberries or raisins for a bit of chewiness. Feeling adventurous? Experiment with different flavored peanut butters, like honey or chocolate peanut butter, to give your cookies a unique twist. The possibilities are endless, and each variation is sure to bring a smile to your face!
