Flour, for pan
1/2 cup sugar
1 teaspoon ground cinnamon
30 buttermilk canned refrigerator biscuits
1 stick butter, plus more for pan
1/2 cup brown sugar
1 cup chopped walnuts

Butter and flour a bundt pan and set aside. Preheat oven to 350 degrees F.
Combine sugar and cinnamon. Cut refrigerator biscuits in half and toss in cinnamon and sugar mixture. Melt the 1 stick of butter in a saucepan and add brown sugar and bring to a boil; then add nuts. Layer the bundt pan with biscuits and butter mixture.
Bake for about 30 minutes. Remove from the pan when it's still hot to avoid sticking.
