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, their measurements, 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.

These Chocolate Peanut Butter Cornflake Cookies are:

super quick and easy to throw together
only 3 simple ingredients
incredibly delicious and very moreish
crunchy AND creamy!

Because these no-bake chocolate cookies can melt quite easily, they are best served chilled, and should be kept in the fridge.

They can be stored in an airtight container in the fridge for up to 3 weeks. They also freeze well for up to 2 months! Thaw overnight in the fridge before serving.
