Chop cranberries by hand or in a food processor with 1 tablespoon of the sugar.
Mix together all the dry ingredients, including the other three tablespoons of sugar.
Cut butter into dry ingredients.
Slightly beat the egg; whisk in milk and cream. Fold into the dry mixture just until moistened.
Add cranberries. Do not over mix.
Spray a baking sheet with nonstick cooking spray and place batter on top. Pat it down until you have a circle of about 12 inches wide and 3/4 inch thick.
Bake at 400 degrees for 16 minutes or until just slightly golden on top. When you insert a knife it should come out dry.
Let cool for a few minutes before cutting into wedges or squares.
