Place the milk and dark chocolate, butter and golden syrup in a pot over medium-low heat. Stir consistently until completely melted. Add the cookie butter and mix until fully incorporated.

Remove from the heat and let cool until it is just warm. Add the marshmallows and mix until just combined. Add the cookie crisp cereal, mini chocolate chip cookies and crushed cookies and fold to combine.

Spray two 9”x9” aluminum foil containers with cooking spray and divide the mixture between both containers. Stick more cookies onto the surface. Cover with aluminum foil, then place this in the fridge (or freezer, if you’re in a rush) until set.

Slice the rocky road into bite-sized squares, and you’re done!
