The filling for this easy pie can be made in about 15 minutes. It's perfect if you're busy and need to use up the rhubarb in your garden. Although homemade pie crust is best, you can use a frozen or refrigerated one to save even more time.
If you don't have any candy bars leftover from Halloween, you will definitely want to buy some to use in this decadent pie. It's easy, there's no crust to roll out, and it ends up with three delicious layers.
