Peanut Butter Cornflake Cookies Recipe
Introduction
Peanut Butter Cornflake Cookies are a nostalgic treat that combines crunchy cornflakes with rich, creamy peanut butter and a touch of sweetness. These no-bake cookies come together quickly and are perfect for a simple snack or dessert.

Ingredients
- 5 cups cornflake cereal
- ⅔ cup light corn syrup
- ¼ cup maple syrup
- ¾ cup white granulated sugar
- 1 teaspoon vanilla extract
- 1 cup creamy peanut butter
Instructions
- Step 1: Line a large baking sheet with parchment paper and set it aside.
- Step 2: Pour the cornflake cereal into a large bowl and set it aside.
- Step 3: In a medium saucepan, combine the light corn syrup and maple syrup. Warm over medium-low heat, stirring occasionally, until the mixture is slightly bubbly, about 3-4 minutes.
- Step 4: Turn off the heat and stir in the white sugar and vanilla extract until well combined.
- Step 5: Using a rubber spatula, mix in the peanut butter until the mixture is smooth and very sticky.
- Step 6: Pour the peanut butter mixture over the cornflakes and gently mix until all the cereal is coated.
- Step 7: Working quickly, use a 1½ tablespoon cookie scoop or a tablespoon to drop spoonfuls onto the prepared baking sheet.
- Step 8: Let the cookies set at room temperature for 10-15 minutes before serving.
Tips & Variations
- For extra crunch, toast the cornflakes lightly before mixing. You can also swap the creamy peanut butter for crunchy peanut butter for a nuttier texture.
- Add a handful of chocolate chips or chopped nuts to the mixture for added flavor and texture.
- If you prefer a sweeter cookie, increase the maple syrup slightly but reduce the white sugar accordingly.
Storage
Store the cookies in an airtight container at room temperature for up to 5 days. If your kitchen is warm, refrigerate to keep the cookies firm. To enjoy, bring them back to room temperature before serving. These cookies do not freeze well due to their syrupy texture.

FAQs
Can I use natural peanut butter in this recipe?
Yes, natural peanut butter can be used, but it may result in a slightly oilier and less sticky mixture. Stir the peanut butter well before measuring to ensure even consistency.
Do I need to bake these cookies?
No, these are no-bake cookies. The heat from the syrup mixture softens the peanut butter and sweetens the cereals, allowing the cookies to set at room temperature without baking.
