Key Ingredients for the Perfect Cookies
This recipe uses simple, common ingredients to create its signature flavor and texture. Here’s what you’ll need:
For the Cookie Dough:
- All-Purpose Flour: Provides the structure for our cookies.
- Unsweetened Cocoa Powder: Use a high-quality cocoa powder for a rich, deep chocolate flavor.
- Baking Soda: Helps the cookies rise and spread.
- Salt: Balances the sweetness and enhances the flavors.
- Unsalted Butter: Make sure it’s softened to room temperature for proper creaming.
- Creamy Peanut Butter: The star of the show! Standard commercial creamy peanut butter works best.
- Granulated & Brown Sugar: A mix of both sugars provides the perfect balance of sweetness, moisture, and chewiness.
- Eggs: Act as a binder and add richness.
- Vanilla Extract: Enhances all the other flavors in the cookie.
For the Mix-Ins:
- Chocolate Chips: Semi-sweet or dark chocolate chips work beautifully to complement the sweet marshmallows.
- Miniature Marshmallows: These are essential for creating those gooey pockets of sweetness.
Step-by-Step Instructions
Follow these simple steps to create the most delicious Chocolate Peanut Butter Marshmallow Cookies.
- Prep Your Station: Start by preheating your oven to 350°F (175°C). Line two large baking sheets with parchment paper to prevent sticking.
- Combine Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set this aside.
- Cream Butter and Sugars: In a large bowl, use an electric mixer to beat the softened butter, peanut butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 2-3 minutes.
- Add Wet Ingredients: Beat in the eggs one at a time, followed by the vanilla extract. Scrape down the sides of the bowl as needed to ensure everything is well combined.
- Combine Wet and Dry: Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough.
- Fold in the Good Stuff: Gently fold in the chocolate chips. The marshmallows will be added later to prevent them from melting completely during mixing.
- Scoop and Bake: Drop rounded tablespoons of dough onto the prepared baking sheets, about 2 inches apart. Bake for 10 minutes.
- Add the Marshmallows: Carefully remove the baking sheets from the oven. Gently press a few mini marshmallows into the top of each partially baked cookie.
- Finish Baking: Return the cookies to the oven and bake for another 2-3 minutes, or until the marshmallows are puffy and slightly toasted.
- Cool and Enjoy: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. They are incredible while still slightly warm!
Tips for the Best Chocolate Peanut Butter Marshmallow Cookies
Unlock the full potential of this recipe with a few expert tips.
- Don’t Overbake: The key to a chewy cookie is to pull them from the oven when they still look slightly underdone in the center. They will continue to bake on the hot pan.
- Use Room Temperature Ingredients: For a smooth, homogenous dough, ensure your butter and eggs are at room temperature before you begin.
- Press Marshmallows Gently: Be gentle when adding the marshmallows to the hot cookies to avoid deflating them.
- Love Peanut Butter? For an even more intense peanut butter flavor, try swirling a small amount of melted peanut butter on top after they come out of the oven, similar to the topping on our Fluffernutter Brownies.
Variations and Substitutions
Make this recipe your own with these fun and easy variations!
- Add a Crunch: Mix in half a cup of chopped peanuts or pretzels for a salty, crunchy contrast.
- Switch Up the Chips: Try peanut butter chips, white chocolate chips, or even butterscotch chips instead of regular chocolate.
- Make it a Fluffernutter: Use a peanut butter cookie base and fold in marshmallow fluff for a different take on the classic combo. If you love that flavor, you must try our easy peanut butter cheesecake recipe.
How to Store Your Cookies
To keep your cookies fresh and delicious, store them in an airtight container at room temperature for up to 5 days. Placing a slice of bread in the container can help maintain their softness. You can also freeze the baked cookies for up to 3 months. To freeze the dough, scoop it into balls, freeze on a baking sheet, then transfer to a freezer bag. You can bake them directly from frozen, adding a few extra minutes to the baking time.
Yes! You can prepare the cookie dough (without the mix-ins) and refrigerate it for up to 3 days. Let it sit at room temperature for about 30 minutes before scooping and baking. You can also freeze the dough balls for up to 3 months.
You can, but you’ll need to cut them into smaller, dime-sized pieces with kitchen shears. Mini marshmallows are recommended as they distribute more evenly and create better pockets of gooiness.
The key is to add the mini marshmallows in the last 2-3 minutes of baking. Press them gently onto the partially baked cookies and return them to the oven just long enough for them to puff up and get slightly toasted.
Store them in an airtight container at room temperature for up to 5 days. To keep them extra soft, you can add a slice of bread to the container.
For best results, use a standard commercial creamy peanut butter like Jif or Skippy. Natural peanut butters that separate can alter the texture of the cookies and may cause them to spread too much.
