Spray a large bowl with oil to prevent the candy from sticking. Measure 8 cups of puffed wheat into the bowl, set aside.
In a small saucepan combine butter, corn syrup, brown sugar and cocoa powder.
Place on medium heat, stirring occasionally until the butter has melted and everything is combined.
Bring the candy to a roiling boil for 3 minutes. Remove from heat, add vanilla extract. Please note when you add the extract the candy will boil faster for a moment until incorporated.
Spray your spatula with oil and poor the candy over the puffed wheat.
Stir until the puffed wheat is evenly coated. The candy will settle at the bottom of the bowl so make sure you scrape the bottom while stirring. You don't want to leave that candy goodness behind.
Spray a dish of your choice before pouring the mixture in. Using the spatula press the mixture evenly into your dish. Make sure not to press too hard or your square will become dense. If you find it easier to use your hands wet them slightly with water before pressing down to prevent the candy from sticking to your hand. Be careful when you do this as the candy will be hot.
Allow the square to cool completely. Run a butter knife along the edges to loosen then flip the square onto a cutting board into your preferred size. Enjoy!
