No clue where my sister found this recipe, but it's really good, and quick. I like fast and easy.
Layer into a 9x13 greased pan, in order:
Peaches - 1 large and 1 small can, with juice
Butter pecan cake mix (just the mix, not the extra ingredients)
1 stick of melted butter
Coconut - however much you like
Pecans or walnuts - however much you like
Bake at 350 for about 40 minutes. (My oven is wishy-washy, so check it at 30.) ;-)
Toss a little flour at your nose so you look industrious.
