How to Make Slow Cooker No-Bake Avalanche Cookies (Rocky Mountain Chocolate Factory Style) Recipe
Step 1: Melt the White Chocolate and Peanut Butter
Start by lining a large baking sheet with parchment paper—it’ll be your perfect non-stick surface for setting these goodies. Place the white chocolate chips and creamy peanut butter into the slow cooker bowl. Cover and heat on low for 30 to 40 minutes, making sure to stir every 10 minutes. This gentle cooking method ensures the mixture melts evenly into a smooth, glossy, and irresistible blend that forms the backbone of your cookies.
Step 2: Fold in the Crunch and Sweetness
Once your chocolate and peanut butter mixture is perfectly melted and combined, turn off the slow cooker. Now it’s time to gently fold in the crispy rice cereal, mini marshmallows, and milk chocolate chips. The key is to be gentle here—fold just enough to coat everything evenly without crushing the cereal. This careful mixing keeps your cookies full of delightful texture and that trademark avalanche effect Rocky Mountain Chocolate Factory is famous for.
Step 3: Shape and Set Your Cookies
Working quickly while the mixture is still pliable, drop spoonfuls onto the prepared parchment-lined baking sheet. These generous mounds will set into beautifully textured cookies without any baking necessary. Let them sit at room temperature for 30 to 45 minutes for the perfect set, or pop them in the refrigerator to speed up the process. Once firm, they’re ready to enjoy!
How to Serve Slow Cooker No-Bake Avalanche Cookies (Rocky Mountain Chocolate Factory Style) Recipe
Garnishes
To dress these cookies up a bit, consider sprinkling a pinch of flaky sea salt on top just before setting—this will brighten the sweet flavors with a subtle contrast. A light dusting of cocoa powder or even a drizzle of melted dark chocolate can add a sophisticated touch that’s sure to impress guests.
Side Dishes
These indulgent cookies go fantastic with a cold glass of milk, a hot cup of coffee, or even a creamy vanilla ice cream scoop for a dreamy dessert duo. Whether it’s an afternoon snack or an after-dinner treat, these easy pairings highlight their richness and make them even merrier to enjoy.
Creative Ways to Present
For parties or gift-giving, stack these cookies in a rustic jar tied with a colorful ribbon or serve them on a charming wooden board surrounded by fresh berries or edible flowers. You can even sandwich a dollop of peanut butter or marshmallow fluff between two cookies to elevate the avalanche experience further—pure cookie bliss in every bite!
Make Ahead and Storage
Storing Leftovers
These Slow Cooker No-Bake Avalanche Cookies (Rocky Mountain Chocolate Factory Style) Recipe treats keep wonderfully well. Store them in an airtight container at room temperature to preserve their chewy texture and fresh flavors for up to three days, or refrigerate to extend their life up to a week. Just be sure to allow them to come to room temperature for that perfect bite!
Freezing
If you want to keep these cookies around even longer, they freeze beautifully. Place them in a sealed freezer-safe container with parchment paper layered between to prevent sticking. Thaw overnight in the fridge and then at room temperature before serving, and you’ll have fresh-tasting avalanche cookies on demand.
Reheating
Since these cookies are no-bake, reheating is all about preference. A quick 10-15 second zap in the microwave can make the peanut butter and chocolate even softer, offering a warm, melty treat. Just be cautious not to overheat to avoid making the texture too sticky.

Can I add nuts to these cookies?
