  • 1 tsp Baking soda
  • 1/2 tsp Salt
Wet Ingredients
  • 1/2 cup Unsalted butter softened
  • 1/2 cup Granulated sugar
  • 1/2 cup Packed light brown sugar
  • 1 cup Creamy peanut butter not natural, stir well if oily
  • 1 Large egg
  • 1 tsp Vanilla extract
Avalanche Mix-ins
  • 1 1/2 cups White chocolate chips
  • 1 1/2 cups Mini marshmallows
  • 1 cup Crisp rice cereal

Equipment

  • Large mixing bowl
  • Electric mixer (stand or hand-held)
  • Rubber Spatula
  • Baking Sheets
  • Parchment Paper
  • Cookie Scoop (1.5-inch / 3 tbsp)
  • Wire Rack

Method
 

Prepare Dry Ingredients
  1. Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper.
  2. In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
Cream Wet Ingredients
  1. In a large mixing bowl, cream together the softened unsalted butter, granulated sugar, and light brown sugar with an electric mixer until light and fluffy, about 2-3 minutes.
  2. Add the creamy peanut butter and beat until well combined and smooth.
  3. Beat in the large egg and vanilla extract until just incorporated.
Combine and Mix-ins
  1. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix.
  2. Gently fold in the white chocolate chips, mini marshmallows, and crisp rice cereal using a rubber spatula until evenly distributed throughout the dough.
Bake the Cookies
  1. Scoop rounded tablespoons (about 1.5 inches or 3 tbsp) of dough onto the prepared baking sheets, leaving about 2 inches between each cookie.
  2. Bake for 9-11 minutes, or until the edges are lightly golden and the centers are just set but still look soft. The cookies will puff up, and the marshmallows will melt and brown slightly.
  3. Remove from the oven and let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. The marshmallows will be very hot and sticky initially.
  4. Serve warm or at room temperature. Enjoy your avalanche cookies!

Notes

For extra gooey centers, you can slightly underbake the cookies. If you like a flatter, chewier cookie, gently press down on the baked cookies with the back of a spoon immediately after taking them out of the oven. Store avalanche cookies in an airtight container at room temperature for up to 3-4 days.

Pro Tips for Making This avalanche cookies

Creating the perfect batch of avalanche cookies is a rewarding experience, and over the years, I’ve picked up a few little secrets to make them truly shine.

When you’re melting the butter, sugars, and peanut butter, make sure it’s smooth and fully combined, but don’t let it boil too long. A gentle simmer is all you need to activate the sugars and create that perfect base.

My Secret Trick: I always lightly grease my hands with a touch of butter or non-stick spray before shaping the cookies. This keeps the mixture from sticking and makes for much neater, happier cookies!

Once you’ve mixed everything, resist the urge to eat it all straight from the bowl (I know, it’s hard!). Letting the mixture cool slightly before adding the white chocolate chips and marshmallows prevents them from melting completely, giving you those wonderful pockets of goodness.

Finally, patience is key! While they’re tempting to devour immediately, allowing your avalanche cookies ample time to set in the refrigerator is crucial for achieving that signature chewy texture and ensuring they hold their shape beautifully.

Fun Variations for avalanche cookies

The beauty of these avalanche cookies is how wonderfully adaptable they are! While the classic recipe is pure perfection, it’s always fun to play with flavors and textures to suit your mood or what you have in the pantry.

For a delightful crunch, try swapping out half the crisp rice cereal for crushed pretzels. My friend, Emily, absolutely loves the salty-sweet combination it brings to these cookies. It adds a wonderful depth!

If you’re a chocolate lover, consider adding a mix of milk or dark chocolate chips alongside the white chocolate. A swirl of melted milk chocolate drizzled over the top once they’ve set is also incredibly decadent.

In the autumn, I sometimes stir in a pinch of pumpkin pie spice with the dry ingredients for a warm, cozy twist. Or, for a burst of color and a different texture, try adding some chopped dried cranberries or even a handful of rainbow sprinkles, especially if you’re making these for a birthday treat! My niece always asks for extra sprinkles!

What to Serve With avalanche cookies

These delightful avalanche cookies are truly a treat on their own, but pairing them with the right accompaniment can elevate the experience even further. Think of it as creating a little dessert moment!

My absolute favorite way to enjoy an avalanche cookie is with a tall, cold glass of milk. It’s a classic pairing that just feels right, bringing me back to snack time after school.

For a more grown-up indulgence, a freshly brewed cup of coffee or a comforting mug of hot cocoa makes a wonderful companion. The warmth perfectly complements the chewy, sweet cookie. My mom always pairs them with hot cocoa in the winter!

If you’re serving them for a special occasion, a scoop of vanilla bean ice cream alongside a warm cookie creates a lovely contrast of temperatures and textures. You could even add a drizzle of caramel or a sprinkle of toasted coconut flakes for an extra touch of flair.

How to Store avalanche cookies

Once you’ve gone to the trouble of making a batch of these glorious avalanche cookies, you’ll want to make sure they stay fresh and delicious for as long as possible! Proper storage is key to preserving that wonderful chewiness.

You can store your leftover avalanche cookies in an airtight container at room temperature for up to 3-4 days. Just make sure they’re completely cooled before packing them away. I like to place a piece of parchment paper between layers if stacking to prevent sticking.

For longer enjoyment, these cookies also freeze beautifully. Place them in a single layer on a baking sheet to freeze solid, then transfer them to a freezer-safe bag or container. They’ll keep well for up to 2-3 months. When you’re ready to enjoy, simply let them thaw at room temperature for about 30 minutes. My personal tip? I sometimes pop a frozen cookie into the microwave for just 10-15 seconds for a warm, gooey treat!

Nutritional Benefits

While these delightful avalanche cookies are certainly a treat, they do offer a few noteworthy components! The peanut butter provides a good source of protein and healthy fats, contributing to a satisfying bite that keeps you feeling fuller. It’s my way of making a sweet indulgence feel a little more wholesome, proving that you can combine deliciousness with simple, nourishing ingredients.

FAQs

What if my mixture is too crumbly?

If your avalanche cookies mixture seems too crumbly, it might need a little more binding liquid. Try adding a tablespoon of melted butter or milk, one at a time, until the mixture comes together and is easier to shape.

Can I make these dairy-free?

Yes, you can! To make these avalanche cookies dairy-free, simply use a dairy-free butter alternative and ensure your white chocolate chips are also dairy-free. The rest of the ingredients are typically dairy-free.

How do I prevent them from sticking?

To prevent your avalanche cookies from sticking to your hands, lightly grease your palms with a little butter or non-stick spray before scooping and shaping. A cookie scoop also helps to create uniform cookies.

Can I use different cereals?

Absolutely! While crisp rice cereal gives these avalanche cookies their classic texture, you can experiment with other cereals. Crushed cornflakes or even a lightly sweetened oat cereal could offer interesting textural variations.

Baking, for me, has always been about more than just ingredients; it’s about creating moments of joy and weaving sweet memories that last a lifetime.
