How to Make Peanut Butter Marshmallow Cookies

  1. Preheat: Set your oven to 350°F (175°C). This is crucial for achieving that perfect cookie texture when you bake your Peanut Butter Marshmallow Cookies.

  2. Cream: In a large bowl, mix together the unsalted butter, creamy peanut butter, brown sugar, and granulated sugar until smooth and fluffy. It should look creamy and well-combined.

  3. Beat: Add in the egg and vanilla extract. Beat this mixture until everything is well incorporated, providing a rich flavor to your batter.

  4. Whisk: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This will ensure your dry ingredients are evenly distributed.

  5. Combine: Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Be careful not to overmix; you want your dough to remain tender.

  6. Fold: Gently fold in the mini chocolate chips and mini marshmallows, making sure they’re evenly spread throughout the dough for that delightful surprise in every bite.

  7. Drop: Using a tablespoon, scoop out balls of dough and place them on a baking sheet lined with parchment paper, spacing them 2 inches apart to allow for spreading.

  8. Bake: Pop them in the oven and bake for 10-12 minutes or until the edges turn lightly golden brown. The cookies should still look soft in the center.

  9. Cool: Allow the cookies to rest on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. This helps them set perfectly.

Optional: Sprinkle a pinch of sea salt on top for an extra flavor boost!

Make Ahead Options

These Peanut Butter Marshmallow Cookies are perfect for busy weeknights or gatherings! You can prepare the cookie dough up to 24 hours in advance. Simply follow all steps until dropping the dough onto the baking sheet, then cover and refrigerate. This helps the flavors meld beautifully and prevents the dough from spreading too much while baking. When you’re ready to bake, just let the dough sit at room temperature for about 10-15 minutes to soften slightly before placing it in the oven. The cookies will still be just as delicious and chewy, allowing you to enjoy fresh, warm treats with minimal effort!

Helpful Tricks for Peanut Butter Marshmallow Cookies

  • Room Temperature Ingredients: Make sure your butter and egg are at room temperature. This helps create a smooth batter and contributes to a delightful texture.

  • Avoid Overmixing: When combining dry and wet ingredients, mix until just combined. This prevents tough cookies and keeps them chewy, just the way we love our Peanut Butter Marshmallow Cookies.

  • Space Them Out: When dropping dough onto the baking sheet, stick to 2 inches apart. This gives your cookies room to spread and bake evenly.

  • Check for Doneness: Look for lightly golden edges, and remember they’ll continue to cook a bit on the baking sheet. Don’t wait until they’re fully set in the oven!

  • Customize Flavor: Feel free to swap in your favorite mix-ins, like chopped nuts or different chocolate varieties. This lets you create a batch tailored just for your taste.

  • Store Properly: To maintain freshness, store your cookies in an airtight container. Add a slice of bread to keep them soft and delicious for days!

Peanut Butter Marshmallow Cookies Recipe FAQs

How do I choose the right peanut butter for my Peanut Butter Marshmallow Cookies?
Absolutely! Opt for a creamy, natural peanut butter that has no added sugars or oils. It ensures a smooth consistency in your dough. If you prefer a richer texture, feel free to experiment with chunky peanut butter for a delightful crunch!

How should I store leftover cookies?
Store your Peanut Butter Marshmallow Cookies in an airtight container at room temperature for up to 3 days. For extended freshness, placing a slice of bread in the container can help maintain their softness. If you want to keep them longer, refrigerate them for up to a week—just make sure they’re sealed tightly to prevent drying out.

Can I freeze my Peanut Butter Marshmallow Cookies? How?
Yes! Freezing these cookies is a fantastic way to enjoy them later. To freeze, first, let them cool completely. Then, lay them in a single layer on a baking sheet and freeze for about 1-2 hours. Once frozen, transfer them to a freezer-safe bag or container, ensuring to squeeze out any excess air. They can last up to 3 months! When you’re ready to indulge, thaw them at room temperature for 15-20 minutes, and warm them briefly in the microwave for that just-baked experience!

What should I do if my cookie dough is too sticky?
Very often, a sticky dough can be a sign of too much moisture from the peanut butter or eggs. Simply sprinkle in a little more flour, one tablespoon at a time, until the dough reaches a manageable consistency and is easy to handle. Don’t forget to chill the dough for about 30 minutes—this helps reduce stickiness too!

Are Peanut Butter Marshmallow Cookies safe for my pets?
It’s best to keep these cookies away from your furry friends. While peanut butter is generally safe for dogs in moderation, the added sugars and chocolate chips can be harmful to pets. Always check for pet-safe treats if you want to share some sweet moments with your four-legged companions!

How can I make these cookies gluten-free?
To make Peanut Butter Marshmallow Cookies gluten-free, simply substitute the all-purpose flour with a gluten-free all-purpose blend. I often find that brands with xanthan gum work best, as they provide similar texture and structure. Enjoy these delectable cookies without worrying about gluten!
