5 layer brownies

I found this delicious recipe at a year of slow cooking. It s so decadent and delicious! I made it for the class, my DH took some to work the next day for lunch they asked him to bring in a whole pan of it.

--1 16 oz package of brownie mix (I used a brand that had chocolate chips in it for extra yum!)
--1/4 cup melted butter
--1 egg
--1/4 cup water
--1 can sweetened condensed milk
--1/4 cup walnuts
--1/4 cup coconut
--1/4 cup oats

--melt butter (you can do this in the crockpot)
--add 1/4 cup of water, the egg, and the brownie mix
-stir until none of the powder is left dry; batter will be quite thick
--pour can of sweetened condensed milk over the top.
--cover milk with a layer of oats, then coconut, then walnuts.
--close up crockpot and cook on high, if using a little crock, low if using a bigger one. Test with a knife after two hours, if it comes out clean, cook for another 20-30 minutes with the lid off to get rid of the collected condensation and to help solidify the condensed milk. You will know this is done when the edges pull away from your stone.
