Turtle Brownies

I found a recipe similar to this one when I was blog surfing. Unfortunately, I can't remember the actual blog I printed it from. Sorry.

1 box chocolate cake mix
1/3 cup milk
3/4 cup butter
1 bag chocolate chips
1 jar caramel sauce
2/3 cup chopped pecans

Melt butter in the microwave and add butter and milk to cake mix. Mix well and add chopped nuts. Pour 1/2 of batter into a greased and floured 9x13 pan. It will be pretty think and hard to spread. I spray some Pam onto a piece of plastic wrap, lay it over the batter and use it as a mess-free way to spread the batter flat. Bake the first layer at 375 for 6 minutes. Remove from oven and pour caramel over baked portion and spread evenly (again, this will be hard unless you heat the caramel first or use the plastic wrap). Sprinkle chocolate chips over caramel and cover chips with remaining batter (use your plastic wrap again). Bake at 375 for 18-20 minutes. Cool completely before serving. These are very gooey and serve better the next day, after they've had time to set up.
