Ingredients you’ll need

Here’s a list of ingredients you’ll need to make these cookies. You can find my recipe card at the bottom of this post for the complete list with their amounts.

  • chocolate (high quality milk chocolate, dark, or semi-sweet)
  • smooth peanut butter
  • Cornflakes

How to make Chocolate Peanut Butter Cornflake Cookies

To make this incredibly simple recipe, add the chocolate and peanut butter to a microwave-safe bowl, and heat in 30 second intervals, stirring after each one, until melted and smooth.

Stir in the Cornflakes until completely coated in chocolate.

Drop spoonfuls of the Cornflake mixture onto a baking tray lined with parchment paper or a silicone mat. You should get about 18 – 20 decent-sized clusters. Allow to set in the fridge for about 30 minutes to an hour.

The printable recipe card with the FULL list of ingredients and instructions can be found at the bottom of this post.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.

Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

I just made these for the first time and I have a new family favorite! It tastes like a candy bar. I used chunky peanut butter and milk chocolate chips. I'll definitely be making these regularly. I halved the recipe, and still had a large tray full (a dozen ice cream scoop sized). Thank you! :)

What's in them that necessitates them needing to be refrigerated?

It's up to you how you store them, but depending on humidity, they may become soft and melty left at room temperature.
