Preheat oven to 350º F. In a medium saucepan, combine 3/4 cup Truvia Brown Sugar Blend, water and coconut oil. Heat to boiling. Pour into a 2 quart casserole dish or a 9x13" pan.
In another bowl, mix Bisquick, Truvia and milk. Pour this over the liquid already in the cake pan - do NOT stir together! Just bake for 30 mins (9x13") or a bit longer for the 2 quart pan, about 45 minutes, or until the cake part at the top is cooked through.
(Will have a delicious layer of ooey gooey caramel at the bottom of the pan with a warm cake on the top)
Serve with light vanilla ice cream or fozen yogurt. Enjoy!
