How to Make No-Bake Cornflake Cookies at Home

Step 1: Create Marshmallow Base

In a large pot over medium-low heat, combine butter and peanut butter. Stir continuously until fully melted and blended. Add most of the mini marshmallows, stirring constantly until the mixture becomes completely smooth and glossy.

Step 2: Incorporate Cornflakes

Remove pot from heat. Gently fold cornflakes into the marshmallow mixture, ensuring each flake gets evenly coated. Sprinkle remaining marshmallows and peanut butter chips (if using) into the mixture. Stir carefully to distribute ingredients without crushing the cornflakes.

Step 3: Shape Cookies

Spray a cookie scooper with nonstick spray. Scoop out uniform portions onto a parchment-lined baking sheet. Lightly grease your hands and gently press each cookie to create a rounded shape, about 1 inch thick. Avoid compacting the cookies too tightly to maintain a light texture.

Step 4: Add Decorative Drizzle

Place peanut butter chips and oil in a microwave-safe bowl. Heat in 30-second intervals, stirring between each session until smooth and fully melted. Transfer the melted mixture to a ziplock bag. Cut a tiny corner to create a piping tip. Drizzle the melted mixture over each cookie in a decorative pattern.

Step 5: Let Cookies Set

Allow cookies to rest at room temperature for 20-30 minutes. The marshmallow mixture will firm up, creating a delightful chewy texture. Serve and enjoy!

Tips for Making the Best Peanut Butter Cornflake Cookies

• Choose the Right Butter: Select room temperature, creamy peanut butter for maximum smoothness and easier melting.
• Control Marshmallow Melting: Stir constantly and keep heat low to prevent burning or sticking to the pot's bottom.
• Fold Cornflakes Gently: Mix ingredients carefully to maintain crunch and prevent crushing the cereal while coating.
• Prevent Sticky Hands: Lightly grease your fingers with cooking spray when shaping cookies to reduce messy handling.
• Perfect Drizzle Technique: Use a ziplock bag with a small cut for precise, professional-looking peanut butter chip decoration.

How to Store and Reheat Cornflake Cookies

• Refrigerate: Store cookies in an airtight container, separating layers with parchment paper to prevent sticking. Keep refrigerated for up to 5 days for best texture and freshness.
• Freeze: Wrap individual cookies tightly in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 weeks, maintaining their delicious crunch and flavor.
• Reheat: Let frozen cookies thaw at room temperature for 15-20 minutes. For a warm, gooey treat, microwave briefly (10-15 seconds) until slightly softened but not melted.

Serving Ideas for Crumbl No-Bake Marshmallow Cookies

• Pair with Creamy Chocolate Milk: Rich, velvety chocolate milk balances the crunchy, sweet cornflake texture and complements the peanut butter's nutty flavor perfectly.
• Match with Cold Vanilla Smoothie: A smooth, chilled vanilla smoothie cuts through the cookie's sweetness while enhancing its marshmallow and peanut butter richness.
• Serve alongside Caramel Latte: Warm caramel notes in a latte highlight the cookie's buttery elements and provide a delightful contrast to its crisp texture.
• Enjoy with Banana Milkshake: Creamy banana shake adds a fruity freshness that elevates the cookie's sweet and salty profile, creating a delectable taste experience.

Creative Variations on Cornflake Cookies

• Chocolate Crunch Edition: Swap peanut butter chips with chocolate chips and add cocoa powder to the marshmallow mixture for a rich chocolate flavor. Drizzle melted dark chocolate on top for extra indulgence.
• Nutty Caramel Cluster: Mix in chopped almonds or pecans. Replace part of the peanut butter with caramel sauce. Sprinkle sea salt on top for a sweet and salty combination.
• Coconut Paradise: Fold shredded coconut into the mixture. Use coconut oil instead of regular oil for drizzling. Garnish with toasted coconut flakes for added texture and tropical flair.
• Berry Bliss Remix: Add dried cranberries or chopped strawberries to the cornflake mixture. Use white chocolate chips for drizzling. Incorporate a splash of vanilla extract for a fruity, creamy twist.
