Instructions
Ready to make these Peanut Butter Cornflake Cookies? Let’s dive in!
Step 1: Prepare Your Pan
Start by lining a baking sheet or tray with wax paper or parchment paper. This is where the cookies will set, so make sure you’ve got a smooth, clean surface for them to cool on.
Step 2: Melt the Butter and Sugar
In a medium saucepan over medium heat, melt the butter and sugar together, stirring constantly. Keep an eye on it as the sugar melts—you want it to come together smoothly without burning.
Step 3: Add the Peanut Butter and Milk
Once the butter and sugar are fully melted and combined, remove the pan from the heat and stir in the peanut butter and milk. Stir until everything is smooth and creamy. The peanut butter will melt into the mixture, creating a deliciously rich base.
Step 4: Stir in the Cornflakes
Add the cornflakes into the peanut butter mixture. Gently fold them in, making sure all of the cornflakes are coated with the peanut butter mixture. Be careful not to crush the cornflakes—keep that crispy texture!
Step 5: Shape the Cookies
Using a spoon or your hands, drop spoonfuls of the mixture onto the prepared baking sheet. Gently shape them into mounds or little cookie shapes, depending on your preference. They don’t need to be perfect—just make sure they’re in roughly the same size for even cooling.
Step 6: Let Them Set
Refrigerate the cookies for at least 1 hour to allow them to set. They’ll firm up as they cool, and you’ll be left with perfect, crunchy peanut butter goodness.
Step 7: Serve and Enjoy!
Once the cookies are set, serve them up! Enjoy that irresistible combination of peanut butter and crunch. Perfect with a glass of milk or just as a snack anytime you’re craving something sweet.
