Puffed Wheat Cake

This amazing confection comes all the way from Calgary, Alberta. The editor of the newspaper I work at brought back three tin-foil wrapped packages of this stuff to our office yesterday, directly from his trip back home. His mom kindly made Puffed Wheat cake for us and in a matter of minutes, it was gone.
My late mother used to make a similar treat: Rice Krispy squares, but she always added a square of unsweetened chocolate to it. This kind of reminded me of that.

• 1/2 cup butter 
• 1 cup corn syrup
• 1 cup white sugar
• 1/4 cup brown sugar
• 6 heaping tbsp. cocoa powder
• 1 tsp. vanilla
• 10 cups of puffed wheat 

1. Combine butter, corn syrup, sugars and
   cocoa powder in a heavy saucepan.
2. Bring to a boil. (Very important)
3. Remove from heat and add vanilla.
4. Pour over puffed wheat
5. Mix well and press into a greased 9 x 13 pan.
6. Wet hands work better than greased hands to handle the
   stickiness so just moisten them with a bit of water.
7. Chill and cut into squares. Yum!
