I use a 4-quart mixing bowl, but just make sure you use a bowl that is large enough to fit everything in.
Line your bowl with parchment paper.
Cut the angel food cake into cubes.
Drain the pineapple and keep 1 cup of the syrup. If it doesn't have a cup of syrup, add water to make 1 cup.
Dissolve both packets in the four tablespoons of cold water.
Add the lemon juice, pineapple juice, sugar, and boiling water to the gelatin. Mix well and put in the refrigerator until it starts to thicken up. About 20-30 minutes.
Once the mixture has thickened a bit, add in the pineapple and fold in the Cool Whip.
Put a layer of cake into the mixing bowl with parchment paper. Then add a layer of the cool whip mixture. Repeat until all is used.
Refrigerate overnight or for at least 10 hours.
When ready to serve, invert the cake onto a platter and frost it with Cool Whip. Sprinkle with coconut and place maraschino cherries on top.
