1 White Cake Mix
1 Package of Jello (I used Strawberry, but you can use any other flavor you wish)
1 Container of Cool Whip
Berries (I used Strawberries and Blackberries, because I couldn't find Blueberries!)
Make cake mix according to directions and let cool. While cake is baking, mix Jello with 1 cup of boiling water (don't add the second cup of cold water). Put in fridge or freezer to cool and thicken just a little - you don't want it to solidify at all. Poke holes in cake with a knife or fork all over. Pour the cooled liquid Jello slowly all over the top, letting it soak into the holes. Top cake with the container of Cool Whip and then top with berries. Refrigerate until ready to serve.
When you cut into it, you will have streaks of jello throughout the inside, keeping the cake moist and giving it a great fruity flavor. The Cool Whip "frosting" keeps it light and a perfect summer dessert!
