How to Make Crumbl No-Bake Marshmallow Peanut Butter Cookies

• Butter and Marshmallow Fusion

Combine butter and peanut butter in a large pot over medium-low heat. Slowly melt while stirring, then add marshmallows. Continue stirring until the mixture becomes completely smooth and glossy.

• Cornflake Coating

Remove pot from heat and gently fold cornflakes into the warm mixture. Ensure every flake gets a luxurious coating. Sprinkle in extra marshmallows and peanut butter chips for extra texture and richness.

• Shaping the Treats

Use a greased cookie scoop to create uniform balls on a parchment-lined sheet. Softly press each ball to create a gentle, rustic shape. Don’t compress too firmly – we want light and airy cookies.

• Drizzle Finale

Melt additional peanut butter chips with a touch of oil in the microwave. Once smooth, transfer to a small bag and create elegant drizzles across each cookie. Let the treats rest and set at room temperature.

• Serving Moment

Wait 20-30 minutes for cookies to stabilize. These no-bake wonders are ready to delight friends and family with their crunchy, gooey perfection.
