Step-by-Step Cooking Instructions

Now, let's break down the process to make these spooky Halloween Monster Cookies. Follow these easy steps to get the perfect batch:
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking and make cleanup easier.
Step 2: Mix Wet Ingredients
In a large bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar using a hand mixer or stand mixer on medium speed. Beat until the mixture is smooth and creamy, about 2-3 minutes. Add the eggs and vanilla extract, and mix until well combined.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, salt, and rolled oats. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.
Step 4: Add the Mix-Ins
Gently fold in the chocolate chips and candy-coated chocolates (M&M's or other similar candies). You can also add any optional ingredients at this point, such as white chocolate chips, marshmallows, or Halloween sprinkles.
Step 5: Scoop and Shape
Use a cookie scoop or a tablespoon to portion the dough into balls, placing them about 2 inches apart on the prepared baking sheets. Gently flatten the tops of the cookie dough balls to create a more even surface for decorating later.
Step 6: Bake the Cookies
Bake the cookies for 10-12 minutes or until the edges are golden brown but the centers are still soft. Be careful not to overbake, as these cookies are best when they’re chewy!
Step 7: Add the Candy Eyeballs
As soon as the cookies come out of the oven, gently press the candy eyeballs onto the tops of the cookies while they are still warm. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Common Mistakes to Avoid
To ensure your Halloween Monster Cookies come out perfectly every time, keep these common mistakes in mind:
- Overmixing the Dough: Overmixing can result in tough cookies. Stir the dry ingredients into the wet just until combined.
- Overbaking: These cookies should be slightly underbaked in the center for a chewy texture. Keep an eye on them around the 10-minute mark to avoid dry cookies.
- Skipping the Eyeballs Too Early: Make sure to add the candy eyeballs while the cookies are still warm. If you wait too long, they may not stick as well.
