Rollercoaster Cookies: A Whirlwind of Flavors and Fun

### Instructions:

#### 1. **Prepare the Dough:**
Start by preheating your oven to **350°F (175°C)**. Line two baking sheets with parchment paper or silicone baking mats to prevent sticking.

In a large bowl, cream together the softened butter, brown sugar, and white sugar using an electric mixer or by hand until light and fluffy. This should take about 2-3 minutes. Add in the eggs, one at a time, followed by the vanilla extract. Continue mixing until everything is well combined.

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix, as this could make the cookies tough. Stir in the rolled oats, which will add a nice chewy texture to your cookies.

#### 2. **Add the Fun Mix-ins:**
Here’s where the “rollercoaster” fun happens! Add in the chocolate chips, white chocolate chips, chopped nuts, mini marshmallows, dried cranberries, candy pieces, and pretzel bits. These ingredients will give the cookies that perfect blend of sweetness, crunch, and a touch of salt. Gently fold the mix-ins into the dough using a spatula or spoon. The dough might seem a bit thick, but that’s exactly what you want for chunky cookies packed with goodies.

#### 3. **Scoop the Dough:**
Using a cookie scoop or tablespoon, scoop out generous portions of dough and place them on your prepared baking sheets. Space the dough balls about 2 inches apart to allow for spreading. Don’t worry if they look a little heaping—these cookies are meant to be big, bold, and full of texture.

#### 4. **Bake the Cookies:**
Bake the cookies in your preheated oven for about **10-12 minutes** or until the edges are golden brown but the centers are still soft. Keep an eye on them as baking times can vary based on your oven. Once done, remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

#### 5. **Enjoy the Whirlwind of Flavors!**
The cookies will be a delightful mix of textures: soft, chewy centers with crisp edges, crunchy nuts, gooey chocolate, and a playful pop of sweetness from the candy pieces and marshmallows. The combination of sweet and salty flavors makes each bite an exciting ride—just like a rollercoaster!

### Tips for Perfect Rollercoaster Cookies:

– **Chill the Dough:** If you want thicker, chewier cookies, try chilling the dough for 30 minutes before scooping and baking. This helps prevent the cookies from spreading too much while baking.
– **Experiment with Flavors:** Feel free to get creative with the mix-ins! Swap out the candy pieces for caramel chunks, use milk chocolate chips instead of semi-sweet, or add coconut flakes for an extra tropical twist.
