And it's delicious, too!
Here's what you do:
BUY: 1 Angel Food Cake bar
1 carton of Cool-Whip
1 bag of frozen berries (I like the mixed berries, but it's really your choice)
When it's time for dessert, pour the frozen berries into a small saucepan. Add a little fruit juice (or fruit-flavored juice, whatever you have on hand will work), a spoonful of sugar, put the pot on the stove and crank the burner up to medium-high. Stir it a little and then let it do its thing. The fruit will break down and start to get all bubbly. Add a little cornstarch, stir it in, drop the heat to medium-low-ish and let it do its thing again. Now, slice the angel food cake bar, putting one slice in each person's bowl. Go back to the fruit sauce. If it's thick enough for you, pour it over the angel food cake. If it's not, add some more cornstarch, stir it in and give it a minute to thicken up. Once you've poured the fruit compote-y-ness over the cake, top with Cool-Whip. Viola! You're done!
I made this up about a year and a half ago and everyone I've served it to just oohs and ahhs over it. (I'm sure plenty of other people have come up with it before me, but that's when I figured it out.) There's roughly 82,000 variations on this, it takes about ten minutes, and it's delicious. I think I'm in love.
