INGREDIENTS1 strawberry cake mix (we used Betty Crocker but any brand should work. Just substitute the water for guava juice).
1 c. guava juice
3 eggs
1/2 -1/3 c. vegetable oil (check the cake box for specifics on oil.)
Cream Cheese layer:
1 (8 oz.) pkg. cream cheese, softened
1/3 c. granulated sugar
1 tsp. vanilla
1 (8 oz.) container Cool Whip, thawed
Guava topping: (this works great for 9x13 pan. For a 15x10 in. pan I will double this topping next time.)
2 c. guava juice
1/2 c. granulated sugar
1/4 c. corn starch
3 T. water
Prepare cake batter according to instructions on the box. Replace the water for guava juice. Pour batter into a greased 9x13 baking sheet. I also like a 15x10 inch cookie sheet for a thinner cake. Bake cake according to instructions on the package. Let the cake cool completely.
While cake is baking you can prepare the cream cheese layer and guava topping.
For the cream cheese layer: In a medium bowl add cream cheese and beat with a mixer until fluffy. Add sugar and vanilla. Combine well. Fold in cool whip and place in refrigerator until ready to use.
For the guava topping: In a medium saucepan bring the 2 c. of guava juice and 1/2 c. granulated sugar to a boil. Remove from heat. In a small bowl combine cornstarch and water. Add cornstarch mixture to prepared guava juice and whisk until well combined. Return to heat and stir constantly until the mixture returns to a boil. Boil for 1 minute until mixture begins to thicken. Remove from heat and let cool.
Once cake is cooled, spread the cream cheese mixture evenly over the cake. Pour the guava topping on top and spread evenly. Refrigerate until ready to serve.
