No-Bake Peanut Butter Marshmallow Cornflake Cookies


  • Author: clarawhitmore
  • Yield: ~20 large cookies

Description

These no-bake cookies are chewy, crunchy, and packed with gooey marshmallow and peanut butter flavor—perfect for quick treats or holiday platters. We doubled the batch for sharing and added white chocolate and a pinch of sea salt to take them to the next level.


Ingredients

Scale

8 tbsp salted butter

1½ cups smooth peanut butter

20 oz mini marshmallows (reserve 2 oz for mixing in)

⅔ cup peanut butter chips (plus ¼ cup for drizzle)

14 cups cornflakes

½ tsp flaky sea salt (optional twist)

⅓ cup white chocolate chips (optional twist)

1 tsp vegetable oil (for drizzling)


Instructions

In a large pot over medium heat, melt butter and peanut butter until smooth.

Stir in 18 oz marshmallows and melt completely. Remove from heat.

Mix in cornflakes, stirring to coat evenly.

Gently fold in 2 oz marshmallows, white chocolate chips, and sea salt.

Scoop into mounds on a parchment-lined tray.

Melt remaining peanut butter chips with oil. Drizzle over cookies.

Let set at room temp for 30 mins or chill briefly to speed it up.
