Reese’s Marshmallow Peanut Butter Chip Cookies Ingredients
For the Cookies
- Butter – Provides richness and moisture; make sure it’s softened for a creamy texture.
- Peanut Butter – Adds flavor and helps bind the ingredients; natural nut butter works but may change the texture.
- Brown Sugar – Contributes sweetness and moisture for that signature chewy texture; always pack it firmly when measuring.
- Milk – Helps combine the dry and wet ingredients; any milk variety can be used, including non-dairy options.
- Vanilla Extract – Enhances flavors; opt for pure vanilla for the best results.
- Large Egg – Binds ingredients and aids in rising; use room-temperature eggs for smoother mixing.
- All-Purpose Flour – Provides structure; gluten-free flour blends can be a great alternative for a gluten-free version.
- Baking Soda – Acts as a leavening agent for added fluffiness; ensure it’s fresh for effective rising.
- Chocolate Chips – Infuses the cookies with delightful chocolatey goodness; dark chocolate chips can provide a richer flavor.
- Reese’s Peanut Butter Cups – Adds surprise bites of flavor and texture; look for regular-sized cups for just the right balance.
- Mini Marshmallows – Bring in the gooeyness; check labels for gluten-free options to cater to all dietary needs.
Step‑by‑Step Instructions for Reese’s Marshmallow Peanut Butter Chip Cookies
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, line a baking sheet with parchment paper or a silpat mat. This will prevent your cookies from sticking, ensuring they bake evenly and release effortlessly when they’re ready.
Step 2: Cream the Butters
In a stand mixer fitted with a paddle attachment, beat together the softened butter and peanut butter on medium speed for about 1 minute. The mixture should become smooth and creamy. This step is crucial for creating a rich base in your Reese’s Marshmallow Peanut Butter Chip Cookies.
Step 3: Add the Sugars
Gradually add the brown sugar into the butter mixture, then continue to beat for about 2 minutes until the mixture is light and fluffy. You should see a noticeable increase in volume and a smooth, velvety texture. This process helps to incorporate air, making your cookies tender.
Step 4: Mix in Wet Ingredients
Next, incorporate the milk, vanilla extract, and large egg into the mixture. Beat everything together until you achieve a smooth consistency, ensuring that the egg is fully combined. This is key to providing moisture and binding the ingredients in your cookies.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and baking soda until well blended. Gradually add this dry mixture into the wet ingredients, mixing just until combined. Be careful not to overmix, as this can lead to tougher cookies instead of the delightful softness you want for your Reese’s Marshmallow Peanut Butter Chip Cookies.
Step 6: Fold in the Goodies
With a spatula, gently fold in the chocolate chips, chopped Reese’s Peanut Butter Cups, and mini marshmallows. Mixing by hand ensures you maintain the fluffy texture while evenly distributing the ingredients, creating pockets of gooey goodness throughout the cookies.
Step 7: Scoop the Dough
Using a cookie scoop or a tablespoon, drop generous amounts of dough onto the prepared baking sheets, spacing them about 2 inches apart. This provides enough room for them to spread. You should start to see lovely dollops of cookie dough, ready to transform into treats in the oven.
Step 8: Bake to Perfection
Place the baking sheet in the preheated oven and bake for about 7 minutes. The cookies should appear slightly golden and puffy but still soft in the center. Be careful not to overbake, as they will continue to set once removed from the oven.
Step 9: Cool and Enjoy
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. This cooling period lets them firm up while maintaining their soft centers. Once they’re at room temperature, store them in an airtight container and savor every delicious bite of your Reese’s Marshmallow Peanut Butter Chip Cookies!

Make Ahead Options
These Reese’s Marshmallow Peanut Butter Chip Cookies are perfect for meal prep, saving you time on busy weeknights! You can prepare the cookie dough up to 24 hours in advance; simply cover the bowl with plastic wrap and refrigerate it. For those looking to save even more time, you can also scoop the dough into balls and freeze them for up to 3 months; just place them on a baking sheet, freeze until solid, then transfer to a zip-top bag. When you’re ready to enjoy, bake the cookies directly from frozen, adding an extra minute to the bake time, ensuring they’re just as delicious as freshly made!
Expert Tips for Reese’s Marshmallow Peanut Butter Chip Cookies
- Use Softened Butter: Make sure your butter is softened to room temperature for a creamy texture; cold butter will make it hard to mix well.

- Parchment Paper or Silpat: Always line your baking sheets with parchment paper or a silpat to prevent sticking and ensure even baking of your cookies.
- Watch the Baking Time: The cookies may look underbaked when you take them out; they’ll continue to cook a bit while cooling, leading to perfectly soft centers.
- Storage Secrets: Store your Reese’s Marshmallow Peanut Butter Chip Cookies in an airtight container to keep them fresh for up to three days; freezing is perfect for longer storage!

Reese’s Marshmallow Peanut Butter Chip Cookies Recipe FAQs
What should I look for when selecting peanut butter for the recipe?
Absolutely! When choosing peanut butter, opt for a creamy variety for a smooth texture. Avoid options that contain added sugars or oils, as they can alter the final outcome. Natural peanut butter is a great choice but keep in mind it may lead to a slightly different consistency.
How should I store leftover cookies?
Store your Reese’s Marshmallow Peanut Butter Chip Cookies in an airtight container at room temperature for up to 3 days to keep them soft and chewy. If you wish to keep them longer, place them in the fridge to extend their freshness, but that may alter the texture slightly.
Can I freeze the cookies for later enjoyment?
Very! To freeze your cookies, first allow them to cool completely. Then, lay them out in a single layer on a baking sheet and freeze for about an hour. Once frozen, transfer them to a freezer-safe bag or airtight container. They can be stored this way for up to 3 months. When you’re ready to enjoy them, let them sit at room temperature or microwave for 10-15 seconds for that fresh-baked taste.
What do I do if the cookies come out too flat?
If your cookies are spreading too much while baking, it could be that your butter was too warm or you didn’t include enough flour. To prevent this, ensure your butter is softened but not melted—room temperature is best! Additionally, you can refrigerate the dough for about 30 minutes before baking to help them maintain their shape.
Are these cookies safe for people with nut allergies?
These cookies contain peanut butter and Reese’s Peanut Butter Cups, which are not safe for individuals with nut allergies. However, if you’re baking for someone with allergies, you can make a nut-free version by substituting peanut butter with sunbutter or another nut-free butter, and ensure that all other ingredients are free from nut traces.
Can I use gluten-free flour in this recipe?
Absolutely! Simply use a gluten-free flour blend instead of all-purpose flour to make this recipe gluten-free. Be sure to check that all other ingredients, especially the chocolate chips and marshmallows, are gluten-free as well to cater to your dietary needs.
