~Thaw completely if using frozen strawberries.
~If using fresh strawberries be sure to chop them, add a little sugar and set aside before you start the cake. This will give the berries time to melt the sugar to make them juicy.
Bake the cake according to box directions making two 9" layers then cool completely.
Place one cake layer into a large clear glass bowl or triffle bowl. Cover with half of the strawberries, then cover with whipped topping. Repeat with second cake layer finishing with whipped topping.
TIP: If using frozen cool whip* be sure to thaw completely. Add in a teaspoon of vanilla and whisk until well blended. This makes it taste more homemade. I have also made this with yellow layers.
NOTE: Throw a little flour on your face and your friends and family will think you've slaved all day!
