In a large bowl combine Bisquick, buttermilk, and sugar using a fork. Mix just until the mix creates a dough.
In another bowl, combine brown sugar, granulated sugar, cinnamon, and nuts. Add a tablespoon of melted butter. Stir well and set aside.
Put the dough onto a rolling surface and pat with your hand into a rectangular shape.
Make the dough as thin as 1/2 inch thick using a rolling pin.
Pour 1/3 cup melted butter onto the dough. Use a pastry brush to spread the butter entirely.
Sprinkle prepared nut- sugar mixture over butter.
Begin to roll the dough, starting from the long end.
When rolled up, slice it into 1/2 slices.
Grease your baking pan, and arrange all slices there.
Transfer to the preheated oven and bake for 25-30 minutes or until golden. When done, let rest 5 minutes.
Prepare the glaze: combine powdered sugar, milk, and vanilla in a bowl until smooth.
Serve drizzled with vanilla glaze.
Notes
This kind of dough is quite sticky. I would recommend you to flour your rolling surface generously before patting the dough. Flour your hands and rolling pin as well.
