Ingredients You’ll Need
- 1 cup creamy peanut butter: This is the heart and soul of the recipe, lending its luscious flavor and creamy texture. You can substitute with crunchy peanut butter for added texture.
- ½ cup (1 stick) unsalted butter: This adds richness to the cookies. Make sure it’s unsalted to keep your cookies sweet.
- ½ cup honey, or pure maple syrup: Either sweetener works beautifully; honey provides a classic flavor, while maple syrup offers a unique twist.
- 1 tsp pure vanilla extract: This enhances the overall flavor profile. Always choose pure vanilla extract over synthetic for the best taste.
- 5 cups cornflakes cereal: The star ingredient that gives these cookies their crunch. Any unsweetened cornflakes work, but feel free to use gluten-free cereal if you have dietary restrictions.

How to Make 5-Ingredient No-Bake Peanut Butter Cornflake Cookies
- Melt the Mixture: In a medium-sized saucepan, heat 1 cup of creamy peanut butter, ½ cup (1 stick) of unsalted butter, and ½ cup of honey (or pure maple syrup) over medium heat. Stir frequently until everything is melted and combined, ensuring it doesn’t boil.
- Combine the Flavors: Once melted, take the pot off the heat. Stir in 1 tsp of pure vanilla extract. This is your chance to dive into that comforting, warm aroma as you mix.
- Add the Cornflakes: Gently fold in 5 cups of cornflakes cereal, along with the sea salt (if using). Make sure every flake is coated in that amazing peanut butter mixture—it’s key for the best flavors!
- Form the Cookies: Line one (or two) large rimmed baking sheets with parchment paper or wax paper. Spoon mounds of the cornflake mixture onto the sheet, spacing them evenly. Get creative with the cookie sizes!
- Chill to Set: Pop the baking sheet in the freezer for about 1 hour or in the refrigerator for about 1.5 to 2 hours, until the cookies are set perfectly.
- Enjoy Your Treats: Use a spatula to carefully peel the cookies off the parchment paper and indulge in your delightful creation!
Storing & Reheating
Store your No-Bake Peanut Butter Cornflake Cookies in an airtight container at room temperature for up to 5 days. They can also be refrigerated for up to 2 weeks. For longer storage, freeze them for up to 3 months in a freezer-safe container, separating layers with parchment paper. To enjoy them again, let them thaw at room temperature. Keep in mind that while freezing won’t affect flavor, the texture may change slightly. Refresh the crunch by placing them back in the freezer for a few minutes before serving.
Chef’s Helpful Tips
- Watch that the butter and peanut butter don’t overheat; just melt until combined to keep the cookies from being greasy.
- If the mix seems too dry and won’t hold together, add a splash more honey or maple syrup to properly bind everything.
- Experiment with add-ins like mini chocolate chips, shredded coconut, or dried fruits for added flavor and texture.
- For a nut-free version, substitute the peanut butter with sun butter or another nut-free spread.
- Make ahead: This recipe comes together quickly, so it’s great for impromptu gatherings or packing lunches ahead of time.
