Use Chocolate Chex Cereal to make crispy and chewy marshmallow cereal treats. Then, add a drizzle of melted chocolate and Nutella to make them even more chocolatey.
Grease an extra-large mixing bowl and an 8-inch or 9-inch square non-stick baking pan with butter or baking spray.
Pour the Chocolate Chex Cereal into the mixing bowl and set aside.
Cut the salted butter into small pieces and place in a medium-large saucepan.
Set the pan over LOW heat.
Allow the butter to begin melting.
Pour the marshmallows into the pan and toss with the melted butter.
Let the marshmallows melt, stirring often until 75% have melted. This will take about 6-8 minutes.
Remove the pan from the heat and stir until the marshmallows are smooth and creamy.
Pour the melted butter and marshmallows over the Chocolate Chex Cereal and stir until the cereal is coated in marshmallows.
Gently press the cereal treat mixture into the greased baking pan. Spread into an even layer.
Combine the chocolate chips and Nutella in a small saucepan.
Set the pan over low heat.
Stir constantly for 1-2 minutes until about 75% of the chocolate has melted. Then remove the pan from the heat and stir until completely melted.
Pour the melted chocolate into a small zip-top bag or disposable pastry bag and pipe the chocolate over the pan of cereal treats.
Set the cereal treats aside for 2 hours, then pop them into the freezer for about 10 minutes until the chocolate firms up.
Remove the treats from the pan and cut them into 16 squares.
Notes
Storage
Store your Chocolate Chex Bars in an airtight container for up to 7 days or freeze for up to 3 months. Thaw frozen treats in the container for several hours before opening to keep condensation from forming on the chocolate drizzle.
Tips
Melt the marshmallows and butter on LOW heat and remove them from the heat when about 75% of the marshmallows have melted. This will keep the marshmallows from getting too hot which causes your treats to be too hard.
