This is my favorite "go to" recipe when I have to make a dessert on the fly. It takes pantry & staple ingredients, prep time is under 5 minutes and start to finish is well under an hour.
You could definitely get more fancy: adding lime zest and fresh squeezed key lime juice would be delicious. Making the graham cracker crust from scratch would be even more delicious. But this is the QUICK & EASY version and still homemade in my opinion.
