first make a white cake as the box describes

let cake cool and poke holes in the cake

make jello as package decribes and poor the still liquid jello over the entire cake.

place in refrigerator for at least 2hrs to cool

take and cover the top with cool whip.

cut strawberries into quarters and mix in blueberries and place all over the top of cool whip.

if you want lower calories use light cool whip and sugar free jello. this makes a cool and refreshing cake that is light and delishes. great for summer and to add flare for July 4th do a flag style cake using the red n white berries. all my friends love this cake.
