The classic Broek Glass Cake is almost too pretty to eat! Made with several different Jell-o flavors, this sweet treat is easy to make and a perfect refreshing bite in the summertime.
Combine lime gelatin and 1-1/2 cups boiling water; stir until gelatin is dissolved. Pour into a lightly greased 8x4-in. pan. Repeat to make the strawberry and orange gelatins in separate pans. Place in fridge for at least an hour until firm.
Combine the crumbs, sugar and butter. Gently press into a greased 13x9-in. dish. Chill in the fridge.
Meanwhile, in a small bowl, soften unflavored gelatin in cold water for 5 minutes. In a small saucepan, bring pineapple juice to a boil. Stir in unflavored gelatin until dissolved. Transfer to a large bowl and let sit to cool down for 20 minutes.
In a large bowl, whisk whipped topping into pineapple juice mixture. When flavored gelatins are firm, carefully cut into 1/2-in. cubes. Gently fold 2/3 of the cubes into whipped topping mixture.
Carefully pour the mixture over the crust. Scatter the remaining gelatin cubes over the top to decorate. Chill in the refrigerator for at least 2 hours.
