- 6 cups Cornflakes cereal: Provides the light, crispy crunch that makes these cookies so unique and airy.

- 1 cup Sugar: Adds the perfect amount of sweetness and helps create that satisfying chewiness.
- 1 cup Peanut Butter: Brings a creamy, nutty flavor and binds the cornflakes with sweetness.
- 1 tsp Vanilla Extract: Enhances the overall flavor with a warm, inviting aroma.

How to Make Peanut Butter Cornflake Cookies Recipe
Step 1: Prepare Cornflakes
Start by measuring out your 6 cups of cornflakes into a large mixing bowl. Take care not to crush them too much as those crisp flakes are the star of the show and give the cookies their signature crunch. Set the bowl aside until you’re ready to mix everything together.
Step 2: Make Syrup Mixture
In a medium saucepan set over medium heat, combine the light corn syrup and sugar. Stir this mixture occasionally, patiently waiting until all the sugar has completely dissolved. The goal here is to create a smooth, glossy syrup that will bind the cookie ingredients perfectly without any grittiness.
Step 3: Add Peanut Butter and Vanilla
Remove the pan from the heat once the sugar is dissolved and immediately stir in the peanut butter and vanilla extract. Keep mixing until the peanut butter melts fully into the syrup, creating a luscious, smooth mixture that smells heavenly and tastes even better.
Step 4: Combine with Cornflakes
Pour your warm peanut butter mixture over the cornflakes in the large bowl. Using a rubber spatula or wooden spoon, gently fold the cornflakes into the sticky, flavorful syrup. Make sure each flake is thoroughly coated but be gentle to keep their crunch intact. This step is key to achieving the perfect texture.
Step 5: Shape Cookies
Now, scoop out small portions of the coated cornflake mixture onto a parchment-lined baking sheet. You can use a cookie scoop or simply two spoons. Gently flatten each mound to form cookie shapes. The cookies won’t be baked, so the shaping is important for their final form. Set them aside to cool completely so they can harden into their chewy, crunchy glory.
Step 6: Make Chocolate Drizzle
While your cookies are cooling, mix the semi-sweet chocolate chips with the vegetable oil in a microwave-safe bowl. Warm in 15-second bursts in the microwave, stirring well between each interval until the chocolate is melted and velvety smooth. This simple chocolate drizzle will add a rich contrast to the sweet, peanut buttery cookies.
Step 7: Drizzle and Set
Once the cookies have hardened, generously drizzle the melted chocolate over each one using a spoon. Allow the chocolate to cool and set at room temperature. This finishing touch not only looks beautiful but also adds a decadent hit of chocolate that makes these cookies irresistible.
How to Serve Peanut Butter Cornflake Cookies Recipe

Garnishes
For an extra special touch, try sprinkling a light dusting of sea salt or crushed peanuts over the chocolate drizzle before it sets. This contrast between salty and sweet elevates the cookie experience and complements the rich peanut butter flavor beautifully.
Side Dishes
These Peanut Butter Cornflake Cookies pair wonderfully with a cold glass of milk or a warm cup of coffee or tea. Their crunchiness and sweetness make them perfect bite-sized companions for any cozy gathering or afternoon pick-me-up.
Creative Ways to Present
Serve these cookies on a festive platter surrounded by fresh fruit or a bowl of mixed nuts. Alternatively, stack a few with a scoop of vanilla ice cream in between for a playful twist on a sundae. They’re versatile, delightful bites that suit any occasion.
Make Ahead and Storage
Storing Leftovers
You can store any leftover Peanut Butter Cornflake Cookies in an airtight container at room temperature for up to five days. This keeps them nice and crisp while maintaining that chewy center that’s so addictive.
Freezing
If you want to keep them longer, these cookies freeze exceptionally well. Place them in a single layer on a baking sheet to freeze initially, then transfer to a freezer-safe container or bag. They’ll keep their texture for up to three months.
Reheating
You don’t need much to enjoy these after storage—simply let frozen cookies thaw at room temperature. To refresh their crunch, pop them into a preheated oven at 300°F (150°C) for 5 minutes. Enjoy them warm or cooled, both ways are delicious.
