- Butter (1 stick, room temperature): Helps create a soft, tender cookie base with rich flavor.

- Brown sugar (½ cup, packed): Brings moisture and a deep, caramel-like note to the dough.
- Egg (1): Binds the ingredients and contributes to the cookie’s chewy texture.
- Vanilla extract (1 teaspoon): Elevates all the sweet flavors with a warm, inviting aroma.
- Flour (1 ¾ cups): The foundation of your cookie, providing structure without heaviness.
- Baking powder (½ teaspoon): Gives the dough a slight lift for a light, tender bite.

How to Make Rice Krispie Treat Cookies Recipe
Step 1: Prepare Your Oven and Baking Sheet
Begin by preheating your oven to 350°F (175°C). This ensures your oven is at the perfect temperature to bake the cookies evenly. Line a baking sheet with parchment paper to prevent sticking and make cleanup effortless.
Step 2: Cream Butter and Sugars
In a large bowl, cream together the butter, sugar, and brown sugar until the mixture becomes smooth and creamy. This step is key for a tender and sweet cookie base, setting the stage for the rest of the flavors to blend beautifully.
Step 3: Add Egg and Vanilla
Mix in the egg and vanilla extract until everything is well combined. The egg adds richness and structure, while the vanilla boosts the sweet and buttery notes, making your kitchen smell amazing.
Step 4: Incorporate Dry Ingredients
Gradually stir in the flour and baking powder. This slow addition helps develop the dough without overmixing, which keeps the cookies light and soft.
Step 5: Fold in Rice Krispies Cereal
Gently fold the Rice Krispies cereal into the dough, distributing that crispy texture throughout each cookie. The cereal adds a fun crunch that’s totally irresistible.
Step 6: Form Dough Balls with Marshmallows
Use a cookie scoop to portion the dough into balls. Flatten each one slightly, place a marshmallow in the center, then carefully roll the dough around it. For an extra crispy touch, coat the outside of the dough balls with more Rice Krispies cereal.
Step 7: Bake to Golden Perfection
Place the prepared dough balls on your lined baking sheet. Bake for 12 to 14 minutes, or until the edges are golden and the centers remain a bit gooey, signaling that perfect marshmallow melty core.
Step 8: Cool and Enjoy
Allow the cookies to cool slightly on the baking sheet to set but still warm enough so the marshmallow stays luscious. These are best enjoyed fresh but can be stored for later indulgence.
How to Serve Rice Krispie Treat Cookies Recipe

Garnishes
For a delightful presentation, sprinkle a little powdered sugar on top or drizzle melted chocolate over the cookies. You can also add a pinch of rainbow sprinkles for a fun, party-ready look that will make everyone smile before they even take a bite.
Side Dishes
Pair these treats with a cold glass of milk or a creamy hot chocolate to complement the cookie’s sweetness and enhance their nostalgic feel. For a brunch twist, serve alongside fresh fruit or vanilla yogurt to balance the sweetness with something fresh and light.
Creative Ways to Present
Try stacking a few cookies with layers of marshmallow fluff or peanut butter between for a cookie sandwich that’s a showstopper. Alternatively, serve the cookies warm with ice cream on the side for a simple but indulgent dessert that everyone will rave about.
Make Ahead and Storage
Storing Leftovers
Keep your leftover Rice Krispie Treat Cookies in an airtight container at room temperature for up to 3 days. This helps maintain their crisp edges while keeping the marshmallow center soft and approachable.
Freezing
If you’re thinking ahead, these cookies freeze beautifully. Place them in a single layer on a baking sheet to freeze initially, then transfer to a freezer-safe container or bag for up to 2 months. Just thaw at room temperature when ready to enjoy.
Reheating
To bring back that freshly-baked warmth, pop the cookies in the microwave for about 10-15 seconds. The marshmallow center will soften again, giving you that gooey delight freshly made. Avoid overheating to prevent melting the cereal coating.
FAQs
Can I use mini marshmallows instead of regular-sized ones?
Absolutely! Mini marshmallows work well and may even melt a little more evenly inside the cookie, although the surprise center won’t be as large.
Will these cookies be very sweet?
They do have a sweet profile since they combine sugars and marshmallows, but the crunch of Rice Krispies adds balance so the sweetness is enjoyable, not overwhelming.
Can I substitute Rice Krispies with another cereal?
You can try cereals with a similar crisp texture, but Rice Krispies are ideal for that classic snap and lightness. Some alternatives might alter the texture and flavor.
What if I don’t have baking powder?
Baking powder gives a subtle lift to the cookies. Omitting it might result in denser cookies, but they will still taste delicious.
Are these cookies kid-friendly?
Definitely! Kids love the chewy marshmallow surprise inside and the fun crunch from the cereal. They’re great for school parties or a special homemade dessert.
