- 1 cup (258 g) creamy peanut butter

- 1 jar (7 ounces) marshmallow fluff
- Mini M&M candies for topping (optional)
Ingredient Notes:
- Butter: Make sure your butter is at room temperature for easy mixing.

Step-by-Step Instructions
Ready to bring these cookies to life? Here’s a detailed breakdown of the steps:
1. Preheat and Prep
Preheat your oven to 350 degrees F (175 degrees C). Line your baking sheets with parchment paper—this helps with easy removal and cleanup.
2. Cream the Butter and Peanut Butter
In a mixing bowl, beat 1 cup (2 sticks / 227 g) room-temperature butter until it’s smooth and creamy. Then add 1 cup (258 g) creamy peanut butter, mixing it until well combined and velvety.
Chef’s Tip: Ensure your butter isn’t too soft or melted; you want it soft enough to cream but not soupy!
3. Incorporate the Sugars
Add 1 ½ cups (300 g) packed light brown sugar and mix until the mixture appears fluffy and light—about 2-3 minutes.
4. Add Eggs
One at a time, incorporate 2 large eggs. Make sure to mix each egg thoroughly before adding the next. This ensures a uniformly batter.
5. Mix Dry Ingredients
In a separate bowl, whisk together 2 cups (250 g) all-purpose flour, 1 cup (90 g) old-fashioned oats, 1 teaspoon baking soda, and ½ teaspoon kosher salt until combined. Gradually incorporate this dry mixture into the cookie batter just until combined—don’t overmix!
6. Fold in Candies and Chips
Gently fold 1 ½ cups plain M&M candies and 1 ½ cups (252 g) semi-sweet chocolate chips into the dough. The colorful candies make it more fun!
7. Form the Cookies
Using a medium cookie scoop, portion out 2-tablespoon dough balls onto the lined baking sheets, spacing them about 2 inches apart. Then, flatten each ball slightly.
8. Add the Marshmallow
Scoop 1 tablespoon of marshmallow fluff and place it in the center of each flattened cookie dough ball. Use another portion of dough to cover it, sealing the edges by pinching the dough together.
9. Bake
Bake for 15-16 minutes, or until the edges are golden brown. Don’t be alarmed if they puff up during baking; they will settle as they cool.
10. Cool
Allow to cool on the baking sheets for a few minutes before transferring to wire racks.
Common Mistake to Avoid: Don’t overbake! The cookies will continue to cook a little on the baking sheet even after you’ve removed them from the oven.
Expert Tips & Tricks
Start with Cold Ingredients: For the best rise, have some ingredients, like butter and eggs, slightly cold, especially in warmer weather.
Storage Recommendations: Store any leftover cookies in an airtight container at room temperature for up to a week. For longer storage, freeze them for up to three months.
Make-Ahead: You can prepare the dough ahead of time. Just cover it and store in the fridge for up to three days or freeze for even longer.
Troubleshooting: If your cookies spread too much while baking, it could be due to too-soft butter or excess liquid. Conversely, if they’re too dry, you might have added too much flour.
Crispier Edges: Want a crunchier cookie? Try chilling the dough for about 30 minutes before baking to firm it up.
Fun Additions: Consider folding in crushed pretzels or potato chips for an extra crunch and unique flavor profile!
Serving Suggestions
These Marshmallow Monster Cookies aren’t just delicious on their own. Pair them with a tall glass of cold milk or a scoop of rich vanilla ice cream for dessert perfection.
