Strawberry Jell-O Cake

I found this on the Kraft website, but I was looking for it because I had this cake years ago at a friend's baby shower and I loved it.  Plus, I had lots of fresh strawberries from our yard to use!  So easy and so delicious!

Ingredients:
1 white cake mix
1 c. boiling water
1 package (3 oz.) Strawberry Jell-O
1/2 c. cold water
1 tub (8 oz.) Cool Whip, thawed

Directions:
Prepare cake as directed in 9x13-inch pan.  Cool cake in pan for 15 minutes.  Pierce cake with large fork at 1/2-inch intervals.  Add boiling water to gelatin mix in small bowl; stir 2 minutes until completely dissolved.  Stir in cold water; pour over cake.  Refrigerate 3 hours.  Frost with Cool Whip.  Refrigerate 1 hour.  Top with fresh strawberries, if desired.

Kraft picture--I forgot.  I topped mine with fresh strawberries, so it was pretty!
