There’s nothing quite like the irresistible combination of creamy peanut butter and fluffy marshmallows to satisfy your sweet tooth! My Favorite Gluten-Free Peanut Butter Marshmallow Cookies are deliciously chewy, delightfully sweet, and packed with protein. Each bite bursts with flavor — chewy, nutty, sweet, and oh-so-satisfying — making them a perfect treat that fits seamlessly into my busy life. I created this recipe on a hectic Sunday afternoon when my family craved something comforting yet wholesome; with just 150 calories each, they prove that treats can be both indulgent and nutritious.
I remember the first time I made these cookies vividly; it was a rainy Saturday afternoon, and my teenagers were stuck at home complaining about boredom. As soon as the warm cookies came out of the oven, the rich aroma filled our kitchen, and I heard my youngest exclaim, “Wow, Mom! These smell amazing!” The secret ingredient that sets these cookies apart is the gooey marshmallow bits mixed in with the peanut butter — it adds a delightful texture that everyone loves. By the end of the day, I had to hide the last few cookies because both kids were clamoring for seconds!
Ingredients for the My Favorite Gluten-Free Peanut Butter Marshmallow Cookies
Each ingredient in this dish plays an essential role in flavor and texture. Here’s what you’ll need:
1 cup peanut butter (creamy or crunchy): Provides rich, nutty flavor and a chewy texture.
1 cup brown sugar (packed): Contributes sweetness and moisture for a soft cookie.
1 large egg (beaten): Acts as a binder for structure and helps create a tender crumb.
1 teaspoon vanilla extract: Enhances the overall flavor with a warm, aromatic note.
1 teaspoon baking soda (gluten-free): Creates lift and helps the cookies spread evenly.
1 cup gluten-free flour (such as almond or coconut flour): Offers the necessary base while keeping the cookies gluten-free.
- 1 cup mini marshmallows: Adds delightful pockets of gooey sweetness throughout.
Step-by-Step Instructions
I recommend starting with preheating your oven to 350°F (175°C) so it’s hot and ready when your cookie dough is prepared, ensuring everything bakes evenly.
Step 1: Preheat your oven to 350°F (175°C). This is an essential first step because you want the cookies to bake perfectly once they’re shaped. While the oven is heating, gather your ingredients, which will make the next steps smoother and quicker.
Step 2: In a mixing bowl, combine 1 cup of peanut butter, 1 cup of packed brown sugar, the beaten egg, vanilla extract, and baking soda. Mix until well combined; I usually use a hand mixer for a smooth consistency—this helps incorporate air into the mixture for that light, chewy texture we love in cookies. Make sure there are no dry pockets of sugar or flour hiding at the bottom!
Step 3: Gradually add in 1 cup of gluten-free flour until a cohesive dough forms. This step is crucial; if you add the flour too quickly, you might end up with clumps that are hard to mix in. I often use almond or coconut flour for this recipe as they provide great flavor and texture while keeping it gluten-free.
Step 4: Scoop tablespoon-sized amounts of dough and roll them into balls. Place them on a baking sheet lined with parchment paper—this not only prevents sticking but also makes clean-up a breeze! I like to space them about 2 inches apart to allow for spreading during baking.
Step 5: Press a few mini marshmallows into the center of each dough ball. Don’t be shy here; I usually go for about three or four per cookie because who doesn’t love that gooey marshmallow center? Just make sure they’re pressing down gently so they stay tucked in while baking.
Step 6: Bake in your preheated oven for 10-12 minutes until the edges are golden brown. Keep an eye on them; they can go from perfect to overdone quickly! The centers might look slightly soft—that’s okay since they’ll firm up as they cool.
Step 7: Remove from the oven and let your cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This cooling time allows them to set properly without falling apart. Trust me; waiting just a bit longer will reward you with cookies that hold their shape beautifully!
What to Serve with My Favorite Gluten-Free Peanut Butter Marshmallow Cookies
This dish is already incredibly filling and balanced, but these sides add extra variety and nutrition to round out your meal perfectly.
Fresh Fruit Salad: A colorful mix of seasonal fruits like berries, bananas, and apples tossed with a squeeze of lime creates a refreshing contrast to the sweet, chewy cookies. The natural sugars from the fruits provide a burst of energy without the heaviness, making this salad a great way to lighten up dessert while adding essential vitamins and fiber. We often make this fruit salad for summer gatherings, as it’s both easy to prepare and always a hit!
Quinoa Salad with Avocado: This protein-packed quinoa salad features diced avocado, cherry tomatoes, and a zesty lime dressing that complements the sweetness of the cookies. With around 8 grams of protein per cup, it boosts your meal’s nutritional profile while providing healthy fats that keep you satisfied longer. It’s a perfect make-ahead option that I whip up on Sundays for quick lunches throughout the week.
Savory Sweet Potato Wedges: Baked sweet potato wedges seasoned with a sprinkle of cinnamon and sea salt create a delicious balance between sweet and savory that pairs beautifully with the peanut butter cookies. They offer complex carbohydrates for sustained energy along with a dose of vitamin A for added health benefits. My kids love helping slice the potatoes and watching them crisp up in the oven!
Chocolate Chia Pudding: Creamy chocolate chia pudding made with almond milk and dark cocoa powder echoes the rich flavors of peanut butter while providing a dose of omega-3 fatty acids and fiber. Each serving contains about 4 grams of protein, making it a nutritious addition alongside your cookies without being overly filling. It’s become our go-to treat for movie nights as it satisfies our sweet tooth with minimal effort!
Storage & Serving Tips
To store your My Favorite Gluten-Free Peanut Butter Marshmallow Cookies, place them in an airtight container at room temperature for up to 5 days. If you want to keep the cookies fresh for a longer duration, consider refrigerating them, where they will last for about a week. Since the cookies contain a chewy marshmallow filling, it’s best to store the — Cookie Base — and the marshmallow filling separately. Keep the cookie base in one container and the mini marshmallows in another to maintain their texture.
When reheating these cookies, preheat your oven to 350°F and warm them for about 5 minutes to restore their chewiness and freshness. Avoid using the microwave as it tends to make the cookies soft and disappointing, compromising their delightful texture. If you’ve stored them separately, you can microwave the marshmallows for about 15 seconds for a melty treat before adding them on top of the warmed cookie base.
Pro tip: To batch cook this recipe for meal prep, consider doubling it on Sundays and portioning them into individual containers for easy grab-and-go snacks throughout the week. Family members can self-assemble their own bowls by adding extra toppings like chocolate chips or nuts for variety. For swaps, try using almond butter instead of peanut butter or adding crushed graham crackers into the — Cookie Base — mixture for a different flavor profile. To keep your marshmallows fresh during meal prep storage, add them just before serving so they maintain their fluffy texture!
