Mix together 1 box chocolate cake mix with ingredients needed to make cake; eggs, oil and water and bake according to directions on the back of the box (using a 9x13-inch baking dish).
While the cake is still warm, gently poke holes in the cake using a fork.
In a bowl, combine 14 ounce can sweetened condensed milk and 7 ounce bag sweetened coconut flakes.
Pour this mixture over the warm cake. Some of the condensed milk should seep a bit into those holes.
In a medium saucepan over medium heat, melt 1/2 cup (1 stick) salted butter along with 12 ounce bag chocolate chips and 1/3 cup milk.
Stir until smooth and completely melted. Do not let this mixture come to a boil.
Take chocolate mixture off of heat and pour on top of cake. Use the back of a spoon or an offset spatula to help spread it out evenly.
Then top with 2 ounce bag sliced or slivered almonds. Slice and enjoy!

Notes
To make this a bit easier to cut into, you can pop the cake in the fridge for about an hour or so to let the chocolate cool and set up a bit.
Some folks may like this with toasted nuts on top. I prefer the raw almonds but feel free to toast them if that is your preference.
